Hi,

According to the seller you have to carefully time the application of
beneficial nematodes. The
soil temps must reach 55F, they must be applied late in the day, and they
must be watered in.

The nematodes are not very active below 55F, the UV rays of the sun kill
them, and the "watering
in" gets them in contact with the soil. The difficult part is getting the
nematodes into the
moist soil, where they live, before the UV rays of the sun kill them or dry
them out.

Luckily, my soild temps are right, and it was raining when I applied them. I
will hope for the
best.

Japanese beetle grubs is one of the target insects for beneficial nematodes.

Later,
Tom
