Q. I have two dwarf apple trees that are four to five years old but have never produced any fruit. I fertilize them every fall. Are there other things I should be doing? – Duane Nagel, Rensselaer, Ind. A. Are your trees blooming? It’s not unusual for dwarf trees to need up to five years before becoming mature enough to bloom. Overfertilizing with nitrogen, a lack of sun or improper pruning may cause a lack […]
Q. Three years ago, I transplanted a couple of peony bushes, which were nice and green, from a neighbor’s yard. Last year, they were green in the spring but the leaves started turning dark brown, some black, with no blooms. This year was the same, except they had a few blooms before turning brown and black. Why is this happening, and what can I do to save them? – Jane Clary, Rockport, Ind. A. Peonies […]
Q. I have two gooseberry bushes that never bloom so, therefore, never produce fruit. They are 8-10 years old and in full sun. Do you have to have male and female bushes to produce fruit? If not, what could be wrong? – Judy Bates, Bloomington, Ind. A. Gooseberries are generally self-fruitful. You are facing another problem since your plants don’t bloom at all. Try pruning out all branches that are more than 3 years old […]
Q: I would like to plant a red rose bush this year, but I don’t know where to start. There is lots of red clay at my house, yet I figure a few bags of topsoil will take care of that problem. When should I plant them? — Ray Padgett, via e-mail. A: Bare-root roses must be planted in the spring, but container-grown roses can be planted any time during the growing season. Dig the […]
Q. I’ve been out in the backyard giving myself a backache chopping down ornamental grasses. We love them 363 days a year; every day except for the two that we spend chopping them down and getting rid of the debris! Any thoughts? – Amy Raley, West Lafayette, Ind. A. We buzz down our ornamental grasses with electric hedge shears and a chain saw. The task goes by quickly! We leave the dried grasses in place […]
Q. Although I am aware of the need to cut back or pinch mums until about the Fourth of July, I need your advice about other flowers, namely daisies, black-eyed Susans, impatiens and petunias. Should all of these be pinched, too, and if so, when? For some time now, I have noticed so many daisies and black-eyed Susans in beautiful clumps standing so stately. As soon as mine are blooming nicely, they begin to droop […]
Q: This spring I would like to plant some blueberry bushes. The soil in this area is mostly clay, with a heavy limestone content. I have dug several holes about 2 feet deep, 3 feet in diameter, and 5 feet apart. The soil from the holes has been mixed with a generous amount of decayed organic matter and replaced. I would like to add an amendment to the mixture to acidify it. However, I have […]
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? […]
B. Rosie Lerner, Consumer Horticulture Extension Specialist Peanuts have long been a popular backyard garden crop in the southern United States, much to the envy of northern gardeners. But since some garden seed catalogs make peanuts available all over the county, peanuts &emdash; also known as goober peas &emdash; are making their way north. Peanuts do require a long, warm growing season of about 120 days. Bright yellow flowers begin to form about seven weeks […]
