Grub damage in your perfectly manicured lawn can be one of the most frustrating problems an avid gardener faces. But don’t despair yet! These easy tips will help you get those pesky pests under control and your beautiful lawn back to its former glory in no time.
How do I know if my problem is grub-related?
The heat of summer leaves lawns dry and parched, and it is natural that a few brown patches will develop. By early autumn, however, you should be seeing an overall improvement and recovery in your lawn. If you find you have a patch that’s refusing to perk up, it’s worth giving it an inspection to be sure these common pests aren’t behind it.
Start off with a gentle tug on the blades of grass in the suspect area. Normal lawn should give you resistance, even if it’s a bit dry. If you find the grass mat is pulling up easily under your hands, you can suspect grub activity and that you have a problem!
What are grubs?
‘Grub’ is a catch-all term for the larval stage of a variety of beetles- Japanese beetles are a classic example, but the specific type will vary from area to area. The grub stage is the third developmental stage from egg to grown insect, and the eggs that are resulting in your current infestation would have been laid down during the summer. By the grub stage, they’re causing noticeable damage. A grub eats everything- and we do mean everything in its path; soil, roots, everything, and the roots of your lawn are a delicious, tasty snack in that voracious diet. The result for your carefully cared-for lawn is that loose feeling and those ugly dying patches.
How do I fix it?
Your first instinct may be to rip up the damaged grass in search of the grubs. Don’t! Your best and most effective route is to treat the lawn- the whole lawn- with a suitable pesticide and water in well. With a good watering, the missing roots will re-grow and the grass will once again take root, and you will be spared the heart- and backbreaking work of replanting whole swathes of your lawn.
There’s one more problem, though. Racoons, possums, skunks and other insect-eating mammals see the grubs as tasty and nutritious snacks. You want to make sure you get your lawn treated before they have an opportunity to do damage digging through your lawn also.
Your heart may sink at the sight of those ugly, rusty lawn patches, but a simple application of a suitable pesticide and some long term TLC and your lawn will be back to perfect in no time.
