Q: I have a large hosta bed and I’m ready to put the semi-annual layer of compost on it. It seems like it would be better to work it in a few inches with my hand cultivator, but I’m afraid of damaging the roots.

A: Working the compost into the soil does make sense. You can use a spading fork to do the job. Apply compost then jab the tines of the fork into the soil multiple times around your plants. You’ll minimize harm to the hostas but give them a root environment they can thrive in.
