Treated Poison Ivy With Brushh Killer Bioadvanced And It Killed Cherry Laurel Bushes Too. Has Thus Now Affected The Soil Too

Question

Treated shrubs with super thrive but it had no affect.

Answer 1

There must have been some drift onto the cherry laurel leaves. The product is systemic and moves through the plant leaves and stems down to the root. The product breaks down quickly in soils.

The best thing to do when you think you inadvertently sprayed a nearby desirable plant with herbicide is to quickly hose it off and continue to flush the plant. If just a few leaves are affected, you can quickly prune them off. Once the product dries on the leaves, there is little you can do to save the plant. If only a small amount drifted, the plants could recover slowly.
