Q. My rhubarb has some type of bug. It’s planted at the edge of my garden. It’s not as hearty as it was in the past, and now it has brown spots. – Phyllis Clark A. Crown rot can cause brown, sunken, water-soaked spots on the base of the leaf stalks. Leaves yellow, and stalks collapse and die. The disease thrives in waterlogged, heavy soils and attacks the crown and base of the stems. In […]
Q. I am wondering what happened to my tomato plants this past year. Early in the season, they started getting yellow leaves at the base of the plant. Then, the leaves dried up; the complete plant almost turned that way. I have them caged, and they grew way above the cages. The tomatoes seemed to be good, but the plants were terrible. Hope you have an answer. – Mrs. Otis Rupright A. Fusarium and Verticillium […]
It seems Indiana gardeners were spending their time preparing for the holidays rather than reflecting on recent garden woes. That means I get a month off! Here are some often-asked questions that I have run before. Q. I didn’t get my spring bulbs planted this fall. Is it too late? A. Your best bet is to plant them as soon as possible. If the soil is not frozen, plant them immediately. When the ground freezes, mulch the […]
Q. How do you start and grow rhubarb? &emdash; Gerald Wicoff, Danville, Ill. A. Rhubarb can be planted in the spring as soon as the ground can be worked. Choose crowns of a known cultivar with at least two large buds. Valentine, Canada Red, McDonald and Ruby are recommended red cultivars. Victoria is a recommended green-stalked cultivar. Valentine tends to produce fewer unwanted seed stalks. Valentine and McDonald require less sugar in food preparation than many […]
Q: I have several hills of rhubarb. For the past three years, the rhubarb has had skinny stalks despite fertilizer, etc. Knowing this probably means I need to divide and re-plant the roots, I need to know when is the best time to do this. Also, I have red seedless grapes that are young and have only been harvested for two years. The grapes are sweet, but extremely small. How does one produce larger fruit? […]
Q: I have hardy kiwi vines that have been planted for six or seven years. Last year they bloomed, but the blooms dropped off. This year they bloomed, and it looked as if little fruit set on. Then those fell off. What could the problem be? I was supposed to have both male and female plants. — Aldona Short, Valparaiso, Ind. A: Several cultural factors can contribute to premature fruit drop. Unseasonable spring frosts often […]
Q. I have this smoketree that is about 10 years old. It will get to the seedy stage, but then it won’t completely bloom out. There might be two or three that will completely bloom out. Do I need more than one tree? Is there such a thing as a male and a female? Please help me get that tree to bloom. — Shirley Sitek, Knox, Ind. A. Smokebush has a rather ineffective flower, but […]
Q. I’ve planted tulips for many years. Last fall, I put about a dozen in a raised bed on the west side of my house. Only two bloomed. The rest had only leaves. What did I do wrong? At the same time, I planted another dozen in front of my house (northwest corner) on regular ground. Every one of them bloomed. The two that bloomed in the bed were the closest to the outside of the […]
