Q. Some years our potatoes and beets have a pitting or scabbing on the surface. It makes them very unappealing to want to eat them. I think they are OK on the inside. What causes this? A.

Q. I have been collecting red and orange Canna seeds this year from plants produced by bulbs at least 3 years old. Can these seeds be propagated? If so, what steps should I take? A.

They can be propagated by seed, but keep in mind that […]

I call them “suckers.” I have cut them off right to the tree base, but they keep coming back. Some of my trees have what looks like a bush surrounding it. This happens with old trees and young trees. What causes this and how […]

Q. My husband pulled out a weed in the garden that made his hands burn for quite a while. It had sharply serrated leaves that were opposite. The stem looks almost square and ropey, with fine hairs along the whole length. Do you have any idea what it is? A.
