When Lightning Strikes, Is The Tree Out?

When lightning strikes a tree, it will most certainly leave a calling card, but it can be difficult to predict whether that injury is “strike one, two or three.” There are many variables to consider, including the species, moisture content, and relative health of the tree at the time of the strike and the intensity of the strike. Lightning can strike just about anything tall, but trees do seem to be a frequent target. And…Read more about When Lightning Strikes, Is The Tree Out?[Read More]

Question and Answer

Q. Three years ago I planted several white pine trees about 6-feet tall. They were doing very well. Then, a short time after a disagreement with one of my neighbors, my pine trees started to die. I planted six trees and every OTHER ONE died. Now I have another maple tree that is dead. I strongly suspect that someone has sprayed some of these trees with Roundup or some other kind of poison. Is there…Read more about Question and Answer[Read More]

Breezing Through Yard and Garden Damage

Recent high winds will no doubt have left their calling card on our yards and gardens. Considering sustained winds of 20-30 mph and gusts up to 40 mph, it’s really quite astonishing that there wasn’t more widespread severe damage. In most windstorms, the trees hardest hit are weak-wooded species, such as silver maples, Siberian elms, river birch and willows. Some trees may have had previously unknown internal decay that resulted in large sections of the…Read more about Breezing Through Yard and Garden Damage[Read More]

Question and Answer

Q. I’ve been interested in purchasing a reel push mower, the kind with no power engine, especially every time I see the price of a barrel of oil rise and every time I try to start my older, smoky power mower. I also like the idea of not polluting the air with noise or exhaust. We have a typical suburban front lawn and a very small backyard (under a lot of trees). Our lawn isn’t…Read more about Question and Answer[Read More]

The most important considerations for getting off on the right foot include site selection, soil preparation and vigorous, disease-free plants.

Question and Answer

Q. My question is about fruit trees. About 8 years ago, I planted 13 semi-dwarf fruit trees: seven apple trees, two apricot, two cherry and two plum. They are now about 15 or so feet tall. There have only been about six apples total. For some reason, that’s about all of the flowers on them. Please tell me, if you can, why the trees do not produce better than they do. A. Achieving a successful…Read more about Question and Answer[Read More]

Temporary Shelter for Bare-Root Landscape Plants

New landscape plants are best planted as soon as possible after they arrive, but gardeners often need to delay planting due to early shipping, weather delays or simply lack of time in busy schedules. So gardeners may need temporary shelter for holding the plants until proper planting can be arranged. When plants first arrive, open the packing material to check on plant condition. Dormant plants are typically shipped bare-root (without soil) this time of year….Read more about Temporary Shelter for Bare-Root Landscape Plants[Read More]
