A look back at the 2012 lawn care season.

There is little disputing the 2012 growing season was a record breaker in more than one area.  Extreme heat and corresponding drought caused widespread damage to even well cared for lawns.  The effect of these weather phenomena then led to massive explosions of pests like grubs and chinch bugs.  Even with November fast approaching, the pest issues will spill over into the spring of 2013, and if left untreated, will continue to cause turf damage.  There is little that can be done for physical lawn repairs at this point in the growing season like bringing in new loam or trying to establish a lawn through seeding.  However, beneficial turf treatments applied now like potassium, lime, compost tea, sea kelp, and slow release fertilizer can help both a damaged and healthy lawn.  Lawn repairs ranging from small to full renovations should be explored now or at least during the winter months as landscapers and lawn care companies will be overwhelmed this spring by sheer volume of repairs necessary never mind pest treatments.  Timing could not be more critical in terms of seeding and treating for damaging turf and ornamental pests than the spring of 2013.  Even if the weather pattern returns to a more “normal” or stable pattern, the repercussions of this season’s heat and drought will continue into 2013.  Although brown grass in October can be a result of past drought and exposure to dry weather, it can also spell bug troubles in the surrounding lawn as grubs vigorously eat fast growing root systems.

Don't wait until the spring to make your lawn plans

I am seeing grubs in record setting numbers and on lawns which have never had a past issue.  While a curative treatment is only a short term fix, a preventative treatment in 2013 may well be in order for more lawns than previously expected.  I do not normally endorse the use of materials to preventatively protect against grubs, which in a normal year are rarely a huge issue unless past history indicates a problem.  However, I will be firmly endorsing both curative and preventative grub control on a case-by-case basis for 2013 because of the high risk factors recently experienced in New England.  Furthermore, another mild winter would further enhance tick populations in 2013 in addition to hundreds of other outdoor pests.  Make a note on your calendar to explore the potential health issues this winter and make plans, if deemed appropriate after speaking to professionals in the industry, such as Chippers.

On the bright side, the recent rain and cooler weather in combination with fall lawn treatments are helping damaged and weak lawns recover to the maximum degree possible before winter.  Don’t dismiss potassium, compost tea, and aeration after the harsh growing season we experienced this past year.  All of these treatments can be done well into November in most of New England so long as the ground does not freeze.

White grubs are eating your lawn without you knowing it!

In closing, don’t forget the millions of crabgrass seeds which were deposited in record numbers along driveways, patios, and walkways because of drought or insect damaged lawns.  Although a thick, healthy lawn is your best defense against crabgrass, some areas will not be up to the task without additional help of a preventative crabgrass barrier in the spring of 2013.  Timing will be key and a lot of good can be done in an eight week period next spring, so don’t file your lawn contract when it arrives this winter, review it carefully and setup a proactive plan to both protect and perhaps restore your home lawn for the investment it truly is!

 

Broadleaf weed problems?

 

As Labor Day approaches, you are likely forced to think about school resuming and the sad state of affairs with your lawn.  If you have an average lawn in New Hampshire or Vermont, you are likely going to find fat broadleaf weeds like plantain, dandelions, and clover among a host of other weedy villains.  Let us not forget to give tribute to the massive crop of crabgrass which has now grown into your driveway, patio, and walkway cracks!  You my friend have lawn problems!  What to do?  There must be something that can be done!

If you attempted to treat for weeds this summer, your efforts were most likely in vain due to high temperatures and dry conditions.  Broadleaf weeds are best reduced when they are actively growing which usually occurs with cool fall or spring weather when soil moisture is adequate.  Any summer spraying usually just causes the surrounding turf to brown under the stress and the weed itself might look a worse for wear but does not die.  This year brought such unusually hot and dry weather, attempting to keep a lawn free of weeds and especially crabgrass seemed like spraying a house on fire with a garden house.  While proper mowing does help, irrigation became vital if your well supported the flow or your town did not put a watering ban in effect.  Brown grass caused the soil to heat up quickly where dormant crabgrass and annual weed seeds popped up and grew overnight, basking in the hot noon sun.  That is the past and explains why your lawn may look the way it does today, even with professional care.

Moving forward, you have two main options, renovate and repair damaged lawn areas to regain lost lawn or go after the weeds once we get cooler, wetter weather.  My advice to most folks is to aerate and seed in the fall and repair any lawn damage without the pressure of crabgrass and annual weeds, that are now dying (something about them dying in the fall).  With reduced competition, fall becomes the best time to overseed and aerate a lawn after a brutal New England growing season.  Go after the weeds next spring when seeding is less effective and crabgrass lurks, just waiting to over run your best efforts in lawn repair.  There is little time now to spray for weeds and seed, given most weed control products have a one month waiting period before seeding is recommended. My advice for the average home owner is to get as much grass back now and then deal with the weeds next spring.  Try improving the soil quality by adding sea kelp or compost tea to get an edge next spring.  The next few months are critical and should be taken full advantage of if you really want to make a difference in your home lawn; not only this fall but to set the stage for the entire growing season of 2013!

Your brown lawn may have more than a color problem

High heat and lack of rainfall has NH & VT lawns turning brown

 

The summer of 2012 is shaping up to be one of record heat, sun, warmth, and drought in many areas across the USA.  While this is fabulous vacation weather for the beach and outdoor activities, your lawn may have gone brown months ago depending upon your location.  In New England, we are experiencing dry weather not felt since the 1950’s.  I don’t imagine Elvis would be pleased to have a brown lawn upon his return home from touring.

At any rate, severe lack of moisture can create other problems beside the straw colored grass you see below your feet.  Extended dry periods cause the soil temperature to dramatically rise, which in turn causes crabgrass and other noxious annual weeds to germinate in earnest.  While your cool weather-loving turf is asleep trying to just survive, weeds can pop up and seemingly grow inches a day.  This is especially true of crabgrass, even with a preventative treatment applied in the spring since the product’s life span only lasts into late July or early August in NH or VT.  Super heated soil creates an ideal growing environment for crabgrass, even in the best cared for lawns.  A light touch is the best course of action until September arrives and restoration efforts can begin.

A more serious side to drought is the fact it attracts all kinds of heat- loving insects like Japanese beetles, chinch bugs and sod webworm to name just a few.  Damage can be occurring right under your feet without a hint of the battle raging in the soil or on the hot brown surface of your beloved lawn.  Left unchecked, fall rainfall comes and your lawn never recovers, which might be attributed to small grubs feeding from late summer right into fall.

Even those grassy areas lucky enough to have irrigation or some shade are not immune to the heat and humidity.  I have seen plenty of brown patch disease rising up overnight due to humidity and wet grass, with the resulting damage visible the next morning.  Mowing grass already in drought conditions or during the heat of the day is like pushing a friend over a cliff with the flu, just plain mean.  The best advice in a hot summer with a significant lack of rainfall is to stay off the lawn if possible, watch and treat for insects as necessary based upon population levels, and irrigate if possible in the morning – even if only for a short period of time.  Even a little water is better than nothing when it comes to keeping the dormant growing point of your grass alive.  Like an IV in a sick patient in the hospital, any moisture applied is better than none in an absence of rainfall.

Any fertilizer used should be at a low rate, slow release, and generally granular in nature.  With autumn only a month away, we are at the top of the roller coaster and things should slowly begin to improve as August fades into September.  If your lawn has taken a hit like many have, plan now to have restoration services lined up in order to take advantage of the best growing time of year for grass – fall!  Services like core aeration, overseeding, lime, compost tea, and organic or natural fertilizers can bring a lawn back to life in preparation for 2013.

Enjoy the heat now because your lawn sure hates it, at least in New England.

Crabgrass in your lawn is more than just a weed problem

Crabgrass solutions

Crabgrass is more than a crabgrass problem!

Enjoy your lawn this year without crabgrass

If you are considering crabgrass control this spring, consider solving the real problem as an alternative spring time lawn project.  If you have a crabgrass problem, you have more than just a crabgrass problem.  The root of the issue is likely unhealthy soil, compaction, and low organic matter; all of which contribute to an inferior lawn.  Most folks will focus on the symptoms of a poor looking lawn such as dead patches or crabgrass and not the underlying issues.  Most lawn issues can be directly attributed to bad soil.  Can there be bad soil?  Well, in a manner of speaking yes, there can be bad soil or at least soil that cannot successfully support good turf growth.  Healthy turf does not occur by accident; it takes a healthy soil to support a green, lush lawn.  Let’s take a closer look at why good soil is so important and why bad soil really can only support crabgrass or nothing at all.

Soil is supposed to be filled with micro-organisms in various percentages, nature’s way of supporting plant life through root systems.  A healthy soil will contain soil particles of various sizes (clay through sand), air spaces, and water.  An ideal soil will also contact organic matter and many micro-organisms such as bacteria, fungi, and protozoa, like in high school biology class (wicked cool).  Turf really appreciates a soil which has a higher bacterial count.  Now you know why grass is always so green over the septic system, an ideal environment for lots of bacteria, organic matter, and moisture.

Poor soil will have a low population of these micro-organisms; in fact, it may not have much, if any at all.  Low organic matter is another issue which takes away from a healthy lawn.  Compacted soils don’t have the air spaces necessary for roots to grow successfully because roots need air to survive.  Add a low soil pH and now you have locked up vital nutrients necessary to support healthy turf growth.

The bottom line is that a good lawn must be rooted in healthy soil.  Without moving forward with proper techniques to improve your soil, your lawn is destined to be a field of crabgrass and blowing dust each and every year. Growing a lawn is just like growing corn or any other crop – it has basic needs.  Crabgrass is much less fussy and will gladly move in without an invitation and stay all summer long, thriving in high heat with minimal rainfall.  Crabgrass is not the enemy; crabgrass is just an opportunist which seizes its ideal growing environment.  The real villain is bad soil that is devoid of air, organic matter, and micro-organisms.

Your real hope lies in compost teas rich in bacteria, fungi, and other “good guys” who helps improve a sterile and almost lifeless pile of dirt.  Sea kelp adds lots of organic matter plus a host of nutrients, proteins, and minerals.  Core aeration breaks up compacted soil, providing air pockets and the opportunity for rain to penetrate a hard surface area.  Organic fertilizers provide more organic matter and a plentiful helping of nutrients, not only the grass, but the living community below!  While crabgrass suppression can be helpful, the real cure lies in improving your lawn’s soil as a basic rule towards creating an outdoor living space that can be enjoyed instead of being cursed.

Do it yourself versus the turf care professional. Reason #3: Results

Bottom line, lawn results count.

 

We understand why folks dabble with their own lawn, from the enjoyment of working outside, to perceived monetary savings.  However, when you boil everything down, isn’t the bottom line results; how good does your lawn look!  Results are the end product of effort, time, and money spent to achieve what most think is a predictable return for the investment.  While this general statement is true, achieving quality results is not such a straight line when we throw in weather, mowing practices, and other variables.

Results are generally backed by past research and historical best practices, yielding a predictable, expected return for the effort.  For instance, crabgrass germinates in the spring at a very specific soil temperature threshold.  History tells us that by reducing the seed population through preventative pre-emergent applications in the spring, a homeowner can expect less crabgrass for that given season.  This would be accurate based upon past research and lots of historical data to back it up.  However, what this best practice does not tell us is what other treatments exist and what bad things can happen after the spring treatment.  In fact, some outdoor activities can actually promote this undesired grassy weed.  Mowing short, high heat, thin turf density, poor soil structure and a host of other factors can directly influence that one “crabgrass” treatment, causing it to either fail early or fail altogether.  Achieving the results we desire can be more complicated than the instructions on the bag would have us believe.

Continuing with the crabgrass theme: there are rates from low to high as it relates to the “weed pressure” within the lawn.  A shady lawn may not require any pre-emergent control, while an open sunny lawn could receive the highest rate due to the exposure and likelihood of crabgrass seeds germinating.  A thin lawn may also be a candidate for a higher rate of this product given the predisposition to crabgrass infiltration.  Determining how to improve results in any of these scenarios requires additional questioning and investigation.  Why is the lawn thin?  Why do I need a crabgrass barrier every spring?  Can I live without this treatment?  What else can I do to improve my lawn?

Looking deeper into obtaining decent results, we find that there is more to the puzzle than an easy “one size fits all” application sold at the local hardware store.  While there is certainly merit in the use of pre-emergent crabgrass control under specific conditions, using it on all lawns year after year may not be the best solution or practice.  Who said that?  I did.

If your lawn is thin and weak, it needs more help than just a crabgrass barrier in the spring.  Without additional assistance, not much else will change and the results will likely stay the same year after year after year.  Like a song on repeat, I can guess what this lawn will look like four years from now without additional interventions like overseeding, improving the soil with lime, more organic matter, topdressing, aeration; I can go on and on.  Results can also be affected by hot or dry weather.  A weak lawn is predisposed to crabgrass and if the weather is hot and dry; you might as well watch the crabgrass germinate like a vine growing in the tropics of Brazil – fast!  Add a short mowing height, and the soil superheats, causing even more crabgrass seeds to germinate in addition to other broadleaf weeds.  Achieving good results on a lawn is more than just a weekend treatment or an occasional cut.  Quality results can only be achieved by looking at the lawn from the soil up and then addressing the issues at hand, one at a time.  The more experienced your lawn care company, the more likely you are to succeed and achieve the lawn of your dreams, no matter where it currently is on the spectrum of green loveliness.  Get results, take your lawn and move it to the next level this season with a different approach.  In doing so, you will achieve results that will save you time, money, and best of all- make you smile when you pull up to your driveway after a hard day of work.

Do It Yourself versus The Turf Care Professional Reason #2: Time and Money

Your free time is worth a lot!

There is an old saying “time is money” which refers to how valuable time is to everyone.  One might say that weekend time, or time away from work might be considered the most valuable, as it relates to family, friends, and recreation.  Time is a premium commodity and is both highly prized and savored by Americans after an exhausting work week.

This exact philosophy applies to caring for your home lawn, regardless of its size.  Many people hire a company to mow their lawn because it saves them hours per week that they can spend doing more enjoyable activities.  The same correlation can be made to applying lawns treatments to keep your lawn healthy and green.  Applying a lawn treatment might seem easy on the surface.  However, doing the treatments right and using the correct products can pose a serious dilemma to the average home owner.  Let’s consider the real cost of time and money involved with these types of activities.

First, you need to have a spray rig or a dry spreader to apply lawn materials.  Most spreaders available at the hardware store are sweet little things, not really setup for ease of use.  Consider hard plastic tires versus air inflated commercial grade tires while walking an acre, no comparison!  Now you have invested in a $60 throw away lawn spreader with no real serviceable parts.  Now comes the hard part, what are you going to put down on your lawn?

A toy spreader for home use, very sweet

You now have to shop for the actual goodies, the fertilizer or lime; perhaps even blended with some other items to knock back weeds, bugs, or minimize crabgrass growth.  There are lots of commercial formulations made by large companies trying to simplify this difficult task by labeling the times of year as “Steps” for instance.  This is where Step One would be in the spring and Four or Five would be in the fall.  While the essence of this seems logical, what is or is not going on in your lawn certainly may not reflect your real lawn care needs at a given time during the growing season.  What’s the big deal you might say?

Well, if you are treating for chinch bugs but really have a grub problem that is a real problem.  You have now applied a pesticide unnecessarily and have not solved the issue at hand.  Don’t forget, these products are not cheap; you can lay down a quick $100 to treat a quarter of an acre without even looking at the receipt.  Don’t forget about the damage still being done or the cost of a lawn renovation.  Diseases and insects are real threats and are not easy to diagnosis without some field experience and education. 

Back to the time element; the time involved shopping, carrying the bags back home, and actual application can easily turn into half a day barring any confusion, weather issues, or other time consuming delays.  Most lawn care products also have rates and ranges, but that assumes you know what you’re treating. The TV ads make treating your own lawn seem easy, like grilling up a burger on a Saturday night, but this is oversimplified.

Best case scenario, you bought everything you need – and used up most of your prized Saturday morning and into early afternoon putting down a weed and feed plus lime, plus crabgrass inhibitor.  Let’s assume you did the job right.  How does this really break down in terms of time and money spent?  Most products you find at the hardware store are either setup for a 5,000 or 15,000 sq.ft. yard. A recent online search brought up the following data to fertilize a lawn and treat it for both broadleaf weeds and crabgrass:

I will use a common lawn size of 8,000 sq.ft. Which means you will need two bags of the aforementioned product @$65 each, now you have to store a partial bag for use next spring.  Hmmm, wonder if it will be useable next year?  $130

1hr shopping for fertilizer and bringing it home   $25

1hr for application/cleanup                                $25

Approximate total cost of $180, excluding your spreader.  Remember, I said the job was done correctly, what if it was not?  Oh my.

A professionally licensed and insured applicator in VT or NH could do the same treatment in 15-20 minutes and charge you between $60 and $95 depending upon your location and actual materials/rates used, which do vary.  The old saying, “you get what you pay for” surely does have a legitimate basis.

If you want the job done right, would like more free time, and still want to enjoy your landscape, perhaps this is the year to explore alternatives to doing the work yourself.  The math sure looks good, what about your lawn?!

July & August can bring out the worst in a home lawn

Classic mid summer crabgrass outbreak

Midsummer weather can put even a great looking lawn into a slow dive of despair without careful attention.  As the heat kicks into high gear, soil temperatures reach their smoking point and crabgrass seeds begin germinating in earnest, popping like corn in a microwave.  Limey green crabgrass plants appear virtually overnight exposing vulnerable areas along driveways, patios, walkways, mailboxes among others.  Where did they come from?  How can they grow so fast?  Ah, the games have just begun!

If you have not watered and your lawn is cut short, now is when your thin lawn becomes choked out with crabgrass plants the size of small cars.  During hot, humid weather, cool season grasses will stop growing, sitting idle while crabgrass seemingly grows an inch an hour, basking in the searing July heat.  A weak or thin lawn, or those lacking a pre-emergent crabgrass barrier, are now at high risk for a crabgrass invasion that will only cease when school reopens.  While post-emergent sprays do exist, spraying at this stage is like using a garden hose on a house fire: it’s best just to let nature take its course.  Measures should be taken in the fall such as aeration, overseeding, lime, and turf thickening fertilizers to help prepare the lawn for the following spring.  A healthy lawn resists this invasion, and although areas may see some crabgrass, it will not be to the point where one could harvest the greenery for salads.

Damaged lawn

A casual glance toward the interior of your lawn may reveal disturbing patches and blotches of varying sizes and colors ranging from brown to white.  How can this be?  What went wrong?  Like a good CSI episode, it is time for the facts to speak and rule out the guessing.  These issues generally fall under environmental stress such as heat, sun scald, or some other non-pathogenic source.  Ruling out diseases can be very tricky depending upon the weather, timing, and location of injury.  This summer has seen a significant upswing in disease-related damage ranging from pits and scars, to unusual patches.  Preventative measures can be taken to help clean up your lawn with either traditional or organic treatments.  Insects are perhaps the easiest to detect given their predicable nature and timing during the season.  Now is a perfect time to treat for grubs, sod webworm, and chinch bugs using either organic or traditional materials.

Doing some simple things properly for your lawn during the next 6 weeks can reduce unsettling issues arising from disease, insects, and environmental stress.  Summer is generally not the best time to spray for difficult to control broadleaf weeds like ground ivy and violets since high heat and low soil moisture content reduce product effectiveness.    If you think you have an invasion at your house, get it checked out and maybe there is a solution to either stop the problem or slow the damage.  Don’t let your lawn scare the neighborhood children – plan ahead and keep it clean and green!

July lawn tips, what to do when you take a vacation

A few easy steps can save your lawn during summer vacation

July is a month where your home lawn can be easily neglected due to many New Englanders seeking out the beach or mountain lakes on summer vacation.  There is a short checklist that can prevent some issues and provide peace of mind while you are away enjoying those early morning beach walks.

Before you depart, make sure your lawn is cut the day before you leave if possible.  If you have a mowing service, the task of mowing is not really an issue.  If you mow yourself, a cut the day before will normally give you a solid 7 to 10 day time frame in which to return without the lawn having grown too long.  In fact, during a hot July period, it is better to go 2 weeks without mowing if the air temperature is in the 80’s and rainfall is absent.  If you return and your grass is really tall, such as over 6”, removal of your clippings is recommended or be sure to rake up the rows of cut grass.

Have your lawn inspected for insect activity; left unchecked, under ideal weather conditions you can lose a lawn in days without curative action.  I have seen a number of lawns with sod webworm damage with the characteristic tan moth taking flight as you walk near.  These small patches are fist size in nature and can coalesce into larger stripes or patches if not treated during the summer months.

Although this season has been on the humid and warm side, promoting diseases over insect activity, a professional lawn evaluation is worth the peace of mind.  If your lawn has confirmed disease issues, it may well be worth a fungicide application to “clean things up” during the July/August period where serious injury can occur.  Summer diseases can easily appear to be drought or insect activity.  Hot weather and warm nights can bring on blotches and spots in mere hours without you realizing the culprit.  You may awake and look out the kitchen window only to ask “Those patches were not there yesterday, were they?”  Thatchy lawns are particularly prone to summer patch diseases, manifesting as scars and pits when placed under stress.

Irrigation or lawn watering is helpful during dry periods but is not necessary during a standard summer vacation.  If you have a sprinkler system or a friend to water, be sure to water in the am or day versus late afternoon, thus minimizing disease issues.  As always, infrequent deep watering is preferred over frequent light watering to promote deeper root systems and minimize disease.  A 1hr watering every other day is generally preferred over a daily 15 minute watering.  Don’t let your lawn stop you from enjoying a great July summer vacation.

Spring Lawn Checklist 2011

Goodbye winter, hello green!

The snow is mostly gone, you may even have a few lingering snow banks that refuse to leave, but for the most part, your lawn is begging for some attention.  Here is a handy spring checklist for your home lawn as you prepare for spring.

1. Plow damage.  It’s been a snowy, rough winter and if you had your driveway plowed, you are likely going to have plow damage.  Chunks of sod and lawn likely got plowed up along the edges and pushed further back onto your lawn.  These pieces of turf chunks may be close to their original location which is now just a scar in the dirt.  If possible, try to put the lawn puzzle back together and place the grass pieces back onto bare soil.  It may well be weeks before anything else can be done and during that time frame, those pieces of grass will start to break dormancy and grow.  Having them at least touching soil is better than mulching your unharmed lawn where they currently reside.  You can always move these grassy sections later and seed as needed into surrounding bare areas.

2. Debris. You may well find gravel, junks of asphalt, branches, leaves, and other debris that simply don’t belong on a grassy surface.  The sooner you can rake and remove this debris, the better.  If the debris is left in its current location, you may not see it during your first mow.  Nothing is more painful than hitting sticks, rocks, and gravel with your mower having been placed onto your lawn by a plow truck.  Leaves left in piles or allowed to matt, especially in shade, will simply mulch any existing grass depending upon its health and density.  The less debris the better.

3. Raking. There are two ways to rake a lawn, one is intentionally damaging- power raking/dethatching, the other is just plain hand raking or using a pull behind tractor implement.  I do not recommend power raking/dethatching unless the lawn has a severe, and by severe I mean a thatch problem- over 1” thick.  Most lawns do not have this kind of depth when it comes to thatch.  As a result, if the average lawn is power raked, it is actually damaged by the process of tearing and cutting.  Since the grass is dormant, and likely stressed by winter ice/snow/cold damage, power raking tears up roots and actually thins a lawn which in most cases is not a desired outcome.  If seeing piles of dead grass blades makes you feel warm inside, you might want to look at a coffee or hot cocoa instead, it certainly will do less damage to your lawn.  I have seen perfectly healthy lawns nearly destroyed by well intended landscapers, only to be called in to repair the damage by overseeding and other processes.  Stick with a hand rake and fluff the lawn up to help it warm and start to grow, or hire someone to do a spring cleanup which includes light raking.  If your lawn has a thatch issue, consider core aeration later in the spring or fall after it has recovered from winter damage.

4. Fertilizer/Crabgrass control. If you are going to use either fertilizer and crabgrass control blended together- don’t put it down too early.  A crabgrass barrier/inhibitor has a limited life span and can easily thin out turf already in a weakened state from winter.  Your best bet is to apply a plain balanced fertilizer to enhance recovery in April, than follow it up with a crabgrass inhibitor in May for maximum results.  This order will accomplish the best of both treatments while not subjecting your lawn to further stress, thinning, or damage.
