Q.
How do I keep grubs out of my rose bushes soil? I have used Bayer advanced
complete insect killer for soil and turf. Active ingredients are Imidacloprid
0.15% B-Cyfluthrin 0.05% and other ingredients 99.80%. I don’t like using poisons as there
are plenty of birds here. However, my roses end up with no roots and miniature
leaves and blossoms as they try to survive. I ran out of wood mulch and have
been using pinecones from the golf course as a temporary mulch. Could this be
the problem? I don’t want to pull up the roses and toss them. They have been
beautiful in the springs and falls of past. Every pinecone I turned over had 2
or 3 grubs under it, on top. Imagine what is down in the soil. Last year just
one rosebush had them. I dug out all the soil and replaced it. I have used this
product twice this year and still have a zillion gross grubs. Please help!!!

at the first comment by a reader regarding grub control. I knew about these beneficial nematodes but
this person is reporting a significant reduction in them over time.
