Gardening editor Doug Oster gets asked a lot of questions. A lot. And he doesn’t mind offering gardening advice. But rather than just limiting those answers to the person who asked, we thought it might be a good idea to share that wealth of knowledge with everybody.
There are three ways to send in your questions:
(The questions may be lightly edited for grammar/clarity/etc.)
Donna: This is my orange azalea bush. I asked you once about the straight branches of wood growing and kept them trimmed as you suggested. Now I looked closer before I was going to cut them and they have buds on them. Do I still cut them or leave them? Also is this a fungus and what do I put on it?
Doug: You’ll want to leave the plant alone. Those buds will open to your flowers. The only time to prune the plant will be right after it blooms, before it puts buds on. If you miss the window, you’ll be removing the buds when you prune and hence the flowers. Those are lichens on the plant, which are not a problem. They are actually a good thing and nothing to worry about.
Marti: You were very helpful when I was concerned about my tulip tree about two years ago. Now I am very concerned about my big old oak tree. It seems to be thinning out and parts of the leaves last summer seemed to be dying as well as some of the branches. I have googled tree doctors, but everything that comes up seems to deal with tree and stump removal. If there is anything that I can do to save it? Do you have any recommendations?
Doug: You need to have an International Society of Arboriculture-certified arborist look at the tree. They will come out for free and assess it. It’s important especially with an oak these days. Oaks must be pruned at the right time of the season as a disease called oak wilt can affect a tree that’s pruned while in active growth.
I’ve used Davey Tree for decades, but full disclosure, the company has been a sponsor of my radio show for the last several years. I used the company 30 years ago when I lived in Ohio and have called on them many times since, here in Pittsburgh.
Gretchen: I have a few questions:
Doug: Here you go:
