Grub Worms A Prob;em
We Will not use chemicals unless the problem is becoming a threat to our crop. In this case out crop we are raising is our lawn. If your lawn is healthy and is getting plenty of sunshine but continues to not get thick you may have a grub worm problem.
I am going to cover the life cycle of the grub worm. In late June what is called a Japanese beetle, these are also called June bugs, they are living in the soil. They will lie in the soil until late June and then fly away. In the month of July they will fly around and mate with each other, and as a result lay eggs in your lawn and become grub worms in your yard. These will then grow up to look kinda like a shrimp that lives underground that is living off of your root system of your grass in your lawn. This is how they survive. In September or October you will begin to see brown spots in your yard, that is aa indication of grubs. Whhen we get get our first freeze, they will then go down in the soil and spend the winter there.
At the beginning of March, they will then begin to migrate to the top surface. They will then do a little bit of feeding at this time, but the yard is growing at such a tremendous pace it will not effect the yard at this time. Do not treat for grub worms at this time. Just wait until later when it is more effective.
To treat for grubs in late May or early June. You will want to put out a preventive. It must be watered into the soil to get into the root system of the plants. When the worm then eats the roots it causes the worm to then always feel fool even when it should be hungry and as a result passing whatever is labeled to kill away.
I you miss this window of time, and start seeing damage from grubs in September. You can then apply a curative. Or whatever is labeled to kill grubs immediately. This will not fix any damage the grub has caused. You may have to do some seeding in the spring to fix the damage they have caused to your lawn.
