Q. I purchased some tulip and iris bulbs on clearance in late November and never got to plant them in the fall. They were in an unheated barn over the winter, and I planted them March 1. Do you think any growth will appear this year or, if not, next year, or are the bulbs dead? – Linda M. Laud A. When we gardeners get to the garden center, we become eternal optimists. We’re just […]
Q. I bought five new rose bushes last spring and planted them in front of my front porch. The area had been well mulched, and the usual clay soil was greatly broken up several years ago when junipers were planted there. The junipers became diseased and died in many places, so we took them out. We thought we shouldn’t plant anything there right away, so we left the area undisturbed for a year. I planted […]
Q. My ornamental grasses are still in place in my yard. They looked nice all winter. When and how do I cut them back? When do I divide them? –Fleet Walker, Nashville, Ind. A. Ornamental grasses can be cut back any time from fall to spring, but I like to leave them in place over the winter. They bring motion and texture to the garden when they’re desperately needed! By late winter, heavy snows and […]
The conflict between trees and utility lines is fresh on my mind, having just experienced the power company removing a significant number of limbs from two lovely old pine trees in the right-of-way behind my property. And I’m in good company with many homeowners who have experienced either the loss of a tree or a significant portion of a tree due to the need to keep the limbs from taking out power to the neighborhood. […]
Q. I had a severe problem with black spot on my roses last season. What can I do, and what can I use to prevent it this year? –Ruth A. Beer, Syracuse, Ind. A. Black spot is a serious problem on roses in Indiana. Black, circular spots with fringed or uneven margins form on upper leaf surfaces in the spring and summer. Spots may also develop on canes and leaf petioles when the infection is […]
There’s no better time of year to browse the new gardening catalogs than during these winter doldrums. A quick glance at the first few pages of most catalogs will clue you in as to what’s new for this gardening season. With all the talk about “nutraceuticals” (foods that promote good health or even prevent disease), there are some new cultivars that offer enhanced nutritional value. Carrot ‘Nutri-Red,’ a red carrot high in lycopene (an anti-oxidant), […]
Q. This spring I got two hibiscus trees and discovered they had spider mites on them. I took them outside and fought them all summer. When I brought them inside, the mites were still there. One day, I sprayed with a spray that I was told to use. They lost all their leaves. Now they are starting to get new leaves. How do I keep the mites off them? How do I care for a […]
Q. I have one ‘domestic’ walnut tree. Every year, just before I think they are ready to be harvested, I come to the tree to find it has been stripped bare. I assume the culprits are squirrels. How can I tell when they are ready so I can get to them first next year? – Irvin Goldstein A. Collecting the nuts before they are truly ripe would lower the quality of the crop. You’re better […]
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 […]
Most gardeners don’t think about burying their roses, but that’s essentially what they should do to protect them from winter’s extremes. Similar to hibernation in animals, roses and other woody plants go through a dormant (rest) period in the winter. The first step to winterizing roses is to keep them healthy through the growing season. Gardeners should protect roses from insect and disease damage and maintain adequate fertility and moisture. After several killing freezes in […]
