PORTSMOUTH, Va. (WAVY) — Dabney Morgan stopped by the WAVY studios Saturday, May 16, 2015 to answer your gardening questions, submitted via Facebook and on air phone calls.
Question from Barbara on Facebook: “I have a rose-bush with holes in the leaves. I tried Bayer Advanced 3 in 1 Rose & Flower, but it hasn’t helped. Is there anything else I can do?”
Answer from Dabney: “The holes are from worms. Try Liquid 7, which is a chemical. If you want to try something organic, use Spinosad. Spray once or twice and that should help.”
Question from Greg in Portsmouth: “I have some camellias, they look kind of scraggly, the leaves are discolored and it didn’t flower much. Someone suggested it might have been from the winter we had. Is there something else I should be looking for or is it from the weather?”
Answer from Dabney: “The weather could have been a variable. If they’re the spring-blooming variety of camellias, make sure they are getting a lot of shade. They do not like the hot afternoon sun. It might be a good time to transplant them if they are getting too much sun. If your flowers have finished blooming, this would be a great time to prune and fertilize to fill them back in.
Question from Charles in Chesapeake: “I’m starting my flower bed, but I’m not exactly sure how to start the flower bed or how to lay the fertilizer in there.”
Answer from Dabney: “Per 100 square feet, I like to mix in 100 lbs. of compost . As far as fertilizer, you only want to fertilize where you plant, there’s no need to fertilize the whole bed. When you’re planting plants or flowers, make sure you plant with the root bulb sticking up a bit above the soil level.”
Question from Susan in Virginia Beach: “You suggested I cut down my oleanders because they sustained some damage from the winter. When I cut them down, it looked like there was a lot of disease inside the areas I cut. Is there something I should put on them?”
Answer from Dabney: “No, not at all. Oleanders don’t really get diseases, it’s just the winter damage. Cut them back and fertilize them and it should come back.”
