Remove Faded Flowers? Yes and No!

Taking time to remove spent blossoms from your shrubs and garden flowers can pay off with more attractive, healthier plantings. The removal of dead flowers is often referred to as “deadheading.” Though it often seems like a big bother, pinching or pruning off dead flowers helps keep plants looking cleaner and prevents them from producing fruit and seed. This allows the plants to put more of their resources into root and foliage growth and development…Read more about Remove Faded Flowers? Yes and No![Read More]

June 1997

Q. I’m having trouble with my tall phlox plants. They are covered with white powder each summer and are smaller than they used to be. The flowers are fewer and smaller, too. Should I spray them with something? &emdash; Jane Small, Fort Wayne, Ind. A. Several factors contribute to vigorous blooming of old-fashioned phlox (Phlox paniculata). The white powder is powdery mildew, and phlox and lilacs are especially susceptible to this fungus. Appropriate fungicides will…Read more about June 1997[Read More]

Q. It looks like moss. It is killing out the grass and taking over my lawn. It started in the shade but keeps spreading. Can you tell me what it is, and what to do about it? – Janice Alward, Kingman, Ind. A. “It” is probably moss, but you could take a sample to your county Extension office to be sure. Moss takes over when conditions aren’t suitable for turf. Infestations are associated with low…Read more about May 1997[Read More]

Q. I enjoy your gardening Q&A and would like to get your opinion about growing okra. Our okra grew OK, but after it bloomed, most of the blooms rotted and fell off. The wife and I like okra, and we’ll appreciate any help you can give us. – Charlie Campbell, Griffin, Ind. A. Okra is a real southern belle, requiring hot temperatures to perform well. Last summer was cool and gray in the early months…Read more about April 1997[Read More]

Q: For the last two years, in the fall, we have had an invasion of ladybugs. They covered the south and west sides of our house. It’s now winter, and we still have ladybugs flying around inside our home. I don’t want to use insecticides, as ladybugs are beneficial, but when there are so many they become a nuisance. Any suggestions or ideas to help us would be greatly appreciated. – Susan Healton, Kokomo, Ind….Read more about March 1997[Read More]

Perennials Offer Ever-changing Garden Views

One of the most exciting and challenging things about a perennial flower display is that the star of the show is always changing. Because most perennial flower species tend to have a limited season of bloom, it takes a little extra effort to be sure there is always something of interest throughout the season. Many gardeners find it useful to plan their garden on paper first, then amend the plan over time. You might start…Read more about Perennials Offer Ever-changing Garden Views[Read More]

Wisteria A Mystery for Most Gardeners

Nothing rivals the beauty of a wisteria arbor in full bloom, but, unfortunately, successfully growing these lovely vines eludes many Midwestern gardeners. Two types of wisteria are most commonly planted in our area: Japanese wisteria ( Wisteria floribunda ) and Chinese wisteria ( Wisteria sinensis). Japanese wisteria is known for its fragrant violet blossoms, which are borne in 8- to 20-inch-long clusters. The individual flowers of a cluster open gradually, beginning at the base. Chinese…Read more about Wisteria A Mystery for Most Gardeners[Read More]

February 1997

Q: I have roughly three acres of land that apparently were cow pasture before our house was built in 1985. I have been trying to reforest this property since 1988. Most of the trees and the grass have been very healthy, including a white oak that must be 150-plus years old. The varieties of trees are diverse on the property. We are only losing wild cherry, maple, ash and willow. My concern is for some…Read more about February 1997[Read More]

Didn’t get your bulbs planted?

If you didn’t get your spring-flowering bulbs planted, you’re not alone. Many gardeners found that autumn rains delayed their bulb planting, only to find a cold snap as the rains let up. The reason for planting bulbs in the fall is twofold. Bulbs require a period of chilling to initiate flowers. For most spring-flowering bulbs, 10 to 13 weeks of temperatures below 40 degrees Fahrenheit are needed. Bulbs also need to put down good root…Read more about Didn’t get your bulbs planted?[Read More]

January 1997

Q: In digging sweet potatoes last week, I, too, found the sweet potatoes hulled out or eaten. There had been a mole run along the sweet potato ridge, and every so far, I would see a round hole made in the mole hill. I dug out shrews, and the potatoes had been freshly eaten on. So, I think the shrews use the mole hill to travel in, and they eat the sweet potatoes and Irish…Read more about January 1997[Read More]
