How to Identify and Get Rid of Cabbage Root Maggots
It looks like I have maggots on the roots of my rose bushes howling them out and killing them so they can anybody help me
It is difficult to say what kind of larvae are boring into your rose roots. To get rid of them: Prune the rose canes to be 5 to 6 inches high, then gently dig up the shrub, hose off the roots (over a barrel or bucket full of warm soapy water) until all of the larvae are gone from the roots, remove the affected soil and replace it with new soil and compost, and replant. If the rose is too badly damaged, consider replanting with a new rose. Be sure the larvae are dead before discarding them. If done in the fall, your rose should bounce right back in the spring.
I pulled my cabbage and sprouts that has CRF, rinsed the soil of them, and the maggots. Planted them back with some ash from the fire/BBQ and they recovered. Then thr bloody butterflies got them!!
