Storing Leftover Garden Seed

If you didn’t use up all of the garden seed you bought this year, much of it can be stored for use in next year’s garden, depending on the plant species. Seeds of some plants, such as corn, parsley, onion, viola (pansies), verbena, phlox and salvia, are not very long lived, lasting only 1 or 2 years at best. Other seeds, including beans, carrots lettuce, peas, radishes, snapdragon, cosmos, sweet William and zinnia will remain […]

Question and Answer

Q. I moved to the country 15 years ago, and started planting oak trees then. I have a problem with my white oaks, but not the reds. The leaves are severely curled up and wilted; new growth comes on and looks good for a short while, then it curls also. The tips are especially affected. The trees are growing, but slowly and look awful. Any idea what to do? A. This sounds like a case […]

All-American Selections New Flowers and Vegetables for 2010

Four exciting new flowers have been chosen as All-America Selections (AAS) 2010, based on superior performance in test gardens throughout the country.

Question and Answer

Q. The last approximately six years have been disastrous for my two cherry trees. The first year, I thinned out the fruit and harvested a light crop. The second year, I had an abundance of fruit but, after a few weeks, all the leaves fell off. The fruit stayed, and I harvested a good crop. The next year, the trees lived a short time and then died. This same thing happened three years before — […]

Blossom-End Rot of Tomatoes Likely This Season

Eager tomato-growers having lovingly nurtured seed to fruit have anxiously awaiting their first ripe gem. But, alas, a black leathery spot appears at the base of the fruit. Blossom-end rot is thankfully not an infectious disease but a frustrating disorder of the fruit. The black scar tissue thought to be caused by a deficiency of calcium in the developing fruit is usually brought on by extreme fluctuations in soil moisture. This year we sure had […]

Q. One of my neighbors recently peeled away a band of bark from his hickory, and I’m wondering if this is a preventative measure against insects or something? Should I be doing this to my hickories? A. Let me preface my reply with the recommendation that most of you should NOT try this at home!

Rose-of-Sharon is a large shrub, reaching up to 12 feet in height and nearly that in spread. The […]

Question and Answer

Q. I enjoy reading your column every month in our Daviess-Martin County REMC Electric/Consumer Magazine. I have learned so much about flower gardening and share several articles with friends. My Amish friends in the Montgomery community have mentioned a “Busy Lizzy” plant that sounds similar to a pink begonia, since it was planted in shade and then taken in for the cold weather. They are no longer able to find any seeds or plants. It […]

Gardening Can Be Hail

Many gardeners, myself included, have had their lovely flowers flattened by hail in recent weeks. Trees and shrubs have had many leaves ripped from the stem, leaving a carpet of drying foliage on the yard and in the house gutters. And it seems that we’re not out of the woods yet, as more storms are predicted in coming days. So what can you do to help plants recover from such damage? The answer depends on […]
