Fall lawn tips

Generally speaking, the summer of 2014 on average was a little cooler and wetter than the past few years. The few hot and humid periods did cause a spike in disease issues like red thread but overall our lawns’ were fortunate not to have to endure extended drought. What does this mean for the average lawn as fall is a mere few weeks away?

Back to school time is fix up your lawn time

First, actively growing lawns means faster recovery and a more robust turf plant going into the winter, especially if you take advantage of the weather. Aerating, over seeding, lime, a few fertilizer applications, and perhaps potassium will put your lawn in top condition for next spring. My advice is not to squander this unique scenario and time period but seize its advantages.
A bit of caution, healthy growing grass can easily mask grubs eating your lawns roots. The classic brown patchiness may not be visible until the invaders are much larger and difficult to control this fall or next spring. If you have not had a preventative grub treatment earlier this year, take a brisk walk around your lawn, especially in the sunny areas, and pull up on the grass to see if it is weakly rooted. If so, you may well see small white grubs within the first few inches of loam below the grass. Treat them now, don’t wait!
Over seeding with such warm, moist soil is a dream come true for lawns and can yield fantastic results to help thicken up your existing lawn. Bare patches should be top-dressed and then seeded after aeration. September and early October are the best time periods to seed a lawn, no question about it. Seed your lawn now, don’t wait until spring!
Healthy grass will grow aggressively and save extra energy down below in the root system. Providing a generous supply of nutrients during the fall allows for a healthy growing lawn that can save extra energy for winter and next spring’s green-up. Don’t forget to fertilizer a few times and be sure to lime. If you forgot to lime this year, it’s never too late as liming any time is just fine.
A final word on year-end lawn mowing. Keep your cut high at 3” for now but you can begin to lower it in October by about ½” per week. The slow decline in height will help harden your lawn off and not expose it to a harsh scalping on one massive slicing. Most lawns will grow well into late November so your final cut should end up at around 1” to 1.5” in November. Mowing short in height is ideal for helping minimize snow mold and winter damage caused by long grass.
This fall could be the best in years, don’t let your lawn miss out on a great growing opportunity.

Double trouble: the Japanese beetle

Published by mrgrass on July 25th, 2013 - in Lawn Pests, Bugs & Insects

The Japanese beetle posses a double threat, both as a ravenous adult beetle chewing on ornamental trees and flowers as well as its juvenile stage as a white grub damaging lawns.  Given the unpopular disposition of this outdoor pest, it may come as no surprise that many homeowners look to reduce its damage both above and below ground.  How can a regular citizen stop sand cherries, crab apples, and roses from being defoliated by this hungry pest?  If you listen at night, in the quiet you can almost hear the crunching as the adult Japanese beetle feasts on its favorite plants in your landscape.  I almost forgot about the lawn!  White Japanese beetle grubs enjoy chewing the roots off your lawn, especially in the spring and fall.  A grub population will sever grass roots turning grass brown and attracting skunks and crows that do even more damage.  The Japanese beetle is truly double trouble above and below ground to any home owner with a sunny lawn and some plantings.

Effective control measures target the grubs in the ground, reducing them while still small in size with a variety of treatment options from standard to organic in composition.  Controlling the larvae or young version of the beetle is not only the most effective means of reducing damage to your lawn and landscape, it is also the least expensive.  Treating the adult beetle is difficult because they are strong fliers and enjoy going out to eat.  Spraying your plants after the adults emerge with successive treatments will reduce population levels and damage to your foliage.  An added benefit of treating your lawn for Japanese beetle grubs is also controlling other pests who can also inflict harm, such as rose chafers.  Even the best looking lawn is no match from the younger form of the Japanese beetle and other white grubs.

Double trouble, the Japanese beetle.

A quick word on pheromone traps, the classic “bag a bug” solution.  These things work well, real well, so well in fact that they call in adults from miles around . . . all to your property.  Like a good BBQ, they will come, eat some shrubs, mate, lay eggs in your lawn, and then fall into the trap.  If you are determined to use one of these pheromone traps, at least put it in the woods or far away from your lawn and landscape as possible.  A better solution is to consider treating your lawn or doing a few spot sprays on susceptible plants as necessary to keep them healthy and with some leaves before fall arrives.

Grubs in your lawn

White grubs in your lawn in June are very difficult to reduce successfully because they are large.  Most grubs are best controlled when they are very small, which generally means a preventative treatment from June to September in NH or VT.  Treating existing grubs which are large are very difficult to control in June.  There are about six or seven types of grubs which are immature beetles and cause turf damage.  While milky spore has some effectiveness in warmer climates, it only controls one grub type and does not do well in colder New England soils; therefore it is not recommended as a useful tool in grub management.

June grub damage in a NH lawn

Grubs at this time of year are very easy to see because they are close to the surface and are as big as they will ever be before turning into beetles.  If your lawn is green and you see patchy yellowing, such as the picture above, grab a handful of grass and gently pull upward.  If you have grubs, you may see one on the first pull as I did in the picture below on a lawn evaluation call for help.  In some cases, extensive ongoing damage may require a swift and aggressive curative treatment to prevent hundreds or thousands of dollars in renovations.  With smaller patches, it may do just to let them be and then treat the next generation during the summer or early fall. This will provide a much more cost effective control and a high degree of satisfaction.

Grub in a NH lawn

Sunny lawns are predisposed to insect infestation because heat attracts pests such as white grubs.  Grubs are one of the most damaging lawn pests and are probably the most well known in gardening circles.  If you suspect grub activity, get a professional to take a look and by no means waste time and money applying milky spore.  Remember, turf management is all about proper pest identification, considering the options, and making a decision to treat or not to treat at the appropriate time.  Don’t let your lawn get eaten underneath your feet!
