The botanical name for daylilies is Hemerocallis. It comes from two Greek words: Hemera is day, and kallos is beauty. The beauty of a daylily flower does last only one day. Thankfully, a mature plant may have over a hundred flowers. Daylilies come in a variety of sizes, colors and shapes.
The smallest daylilies are under a foot tall, and the ...Read more
Are you a plant-watcher? It may sound boring, but it can be interesting -- especially when something begins to harm your plants. If you pay attention to how your plants are growing on a regular basis, you will notice plant problems as they begin to develop. You will also have a better idea of how the plant is supposed to look when it is healthy ...Read more
Q: I've got two trees in my yard that were pruned years ago -- before I bought -- by someone who had no idea what they were doing. The result is large branches that look like "clubs." All new growth comes from the end of the clubs. Imagine your forearm as the branch and your fist as the end, with a branch or two growing in every direction. What ...Read more
Q: Our landscape has been invaded by ants. Actually, the ants aren't out in the landscape but instead are in all the flowerpots on the patio, in between the patio bricks, in the shed, on the tree trunk next to the patio and, unfortunately, coming in the kitchen. We don't see any out in the garden or lawn. Bait traps seem to be starting to work, ...Read more
Many areas have continued to experience heavy rains recently, and a number of places are still flooded from previous storms. This will lead to the next natural phenomenon: mosquitoes. Of course, mosquitoes occur every summer, but there are some things you can do about them.
There are about 200 species of mosquitoes in North America. The biggest...Read more
I was gone for most of Memorial Day. When I got home, something strange was happening in my pond. Many of the goldfish and some of the koi were behaving abnormally. They were lethargic, and some were staying directly under the waterfalls in an apparent attempt to get more oxygen. Before the next morning, a 21-inch-long koi, a foot-long koi and ...Read more
Q: I have a plum tree with little holes in the leaves. This happened last summer and again this spring. Can you tell me again what the cause could be and how to treat it?
A: Plums, apricots and peaches all get a bacterial disease called "bacterial leaf spot." It is also commonly called "shot hole disease," because it looks like someone stood ...Read more
Q: In last week's article, you commented that one of the factors of plant deaths over the winter is the timing of fall pruning. I thought we were supposed to prune our trees and shrubs in the fall: Can you go into more detail on when we are to prune trees and shrubs?
A: Since we are still in spring, let's start there. We prefer to prune spring-...Read more
Q: Apparently the polar vortex last winter killed several of my trees and shrubs. I had carefully selected the plants based on the hardiness zone maps in plant catalogs and on plant tags. I know it was cold, but shouldn't the plants have done better? Some of the trees were planted five to 10 years ago, but some of the shrubs were planted last ...Read more
Q: I need to replace a pear tree. The first one was planted in the fall; last spring, it didn't bloom, which is normal for a newly planted pear. However, what wasn't normal was that the tree started dying from the top down. It was exhibiting the symptoms of fire blight, which, as you know, is a quick-acting and deadly disease in pears. Fire ...Read more
Q: I have several apple and pear trees that I have treated with the fungicide Captan for several years to try to prevent fungal disease problems. It doesn't seem to work. Last year, I specifically didn't treat some branches of the trees to see if I could tell the difference. There was no difference. What can I do to protect my fruit trees?
A: ...Read more
Q: I would like some suggestions for what to do with all the pine cones that fall in my yard from the pine trees (other than just burning them, which so far, I have never done). I don't want them to make more trees. Have you got any suggestions? These are not the really attractive cones that can be used decoratively. They are just ordinary, ...Read more
