Fertilize Woody Plants This Fall

(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]

Keep Plants Watered for Drought Recovery

(Released: 19 October 1995) By B. Rosie Lerner Extension Consumer Horticulture Specialist 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…Read more about Keep Plants Watered for Drought Recovery[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]

Q. We have six flowering dogwood trees in our yard that are approximately 3 years old. (They have not flowered, yet.) Our yard is adjacent to a cornfield. Our problem is Japanese beetles. They especially like our dogwoods. According to publication E-75 from the Purdue University Cooperative Extension Service on Japanese beetles, flowering dogwoods are “relatively free of feeding by adult Japanese beetles.” Our dogwoods are not “relatively free.” Why are the Japanese beetles feeding on…Read more about September 1995[Read More]

Bring in Flowers for Drying

It may be too hot for outdoor chores, but you can still quench your thirst for gardening by bringing in your flowers for drying. Dried plant materials can last almost forever when properly harvested and preserved. Some plants are naturally dry, while others must be processed to remove moisture. Those that are naturally dry, such as grasses, pine cones, cattails and dried seed pods, will need little processing before arranging. Harvest grass plumes after they…Read more about Bring in Flowers for Drying[Read More]

August 1995

Q. For three consecutive years I’ve grown tomato plants and lost at least half of my harvest because the tomatoes rot on the vine. I’ve purchased several gardening books, and none seem to explain the problem. The rotting area starts from the bottom and spreads through until the whole fruit is rotten. I’ve even changed varieties, but with no luck. Is this a disease, or could I be doing something wrong? – Greg Faucett, Tell City,…Read more about August 1995[Read More]
