Q. I have been told that applying lime around pecan trees will increase nut size. Is this true? If so, how much and how often should it be applied, or what should the pH be? Are the pH requirements the same for other nut trees? Do English walnut trees leave toxins in the soil as black walnuts do? Can an old English walnut be replaced with a young one at the same site? I have some…Read more about January 1996[Read More]
For gardeners who are itching to get their green thumbs dirty, repotting houseplants can be a good wintertime activity. But not all plants will need, or even benefit from, repotting. Fortunately, there are several indications to look for to determine if your plant needs new living quarters. The main reason for repotting is to give the roots more room to grow. Perhaps one of the most obvious signs is when the plant is physically too…Read more about Repotting Houseplants Good Winter Activity[Read More]
While the poinsettia remains the most popular of the holiday plants, a healthy Christmas cactus in full bloom is a great gift idea for that special gardener. But along with that bounty of blooms, send these tips for keeping the plant looking its best. Most blooming plants will keep their blossoms longer in cooler temperatures. Keep the plant in a well-lit location away from drafts from heat vents, fireplaces or other sources of hot air….Read more about Care of Christmas Cactus Important After Holidays[Read More]
Q: I have been trying to raise tomatoes on trellises for several years with not too much success. I tried shorter trellises, several different fertilizers and ground-up eggshells for copper and calcium. My plants grew tall vines, went above the trellis by about 3 feet and fell over, ruining my pepper plants next to them. Also, I had brown spots on the tomatoes. I tried different varieties, so variety isn’t a factor. Could you enlighten me,…Read more about December 1995[Read More]
Q. How do I get rid of these small, round, red-orange bugs that look like ladybugs? They are swarming on our screens, doors and porches trying to get in the house, and many of them succeed. Nothing seems to discourage them. If you happen to smash them, there is a terrible odor. I don’t know if they damage anything, but they sure are annoying. Thanks for all your useful answers. – Ellen Roe, Crawfordsville, Ind. A. I…Read more about November 1995[Read More]

Much of Indiana found rainfall scarce throughout the summer, and even into the fall, so gardeners need to make sure their landscape plants have an adequate supply of moisture before winter arrives. Most plants could benefit by a deep watering every couple of weeks or so, right up until the ground freezes. But some plants will need even closer attention. Newly planted trees and shrubs may have limited root systems and may need a weekly…Read more about Keep Plants Watered for Drought Recovery[Read More]
(Released: 05 October 1995) By B. Rosie Lerner Extension Consumer Horticulture Specialist Although most people think of spring as the time to fertilize, fall feeding can give trees and shrubs a boost. Not all landscape plants need fertilizer, but young plants and those that are recovering from stress can benefit. Timing fall fertilizer application is important because feeding too early can promote late fall growth. Young tissue will not have a chance to harden off…Read more about Fertilize Woody Plants This Fall[Read More]

Q: I have a couple of very large tulip beds (700 to 1,000 bulbs), and I usually keep them weeded by hand after the tulips have died down in the spring. Would it be all right to spray the grass and weeds that come up in the beds with Roundup in July or August? It would be a lot easier than hand-weeding the beds all summer. But would this harm the tulip bulbs in the ground?…Read more about October 1995[Read More]
