Question: I have a few older trees and I am concerned that they may not be safe. What should I do?
Answer: Winter is a good time for safety inspections of older trees. Trees with decay or other obvious problems and those in potentially dangerous locations should be inspected by a professional arborist. You can find arborists in your area who are certified by the International Society of Arboriculture and clicking on Find an Arborist.
If you do you own visual inspection start at the top or bottom of the tree and work carefully to the other end.
Look for signs of trouble such as:
Cavities
Broken Branches
Branch Stubs
Limbs that Cross and Rub
Gouges or Unnaturally Loose or Peeling Bark
Bare branches at this time of year make it easier to spot problems. Winter is also an excellent time to contact a tree care company to do any corrective pruning that will make your tree safer. Most companies are less busy at this time of year, and in colder climates the frozen soil will help prevent soil compaction by workers or vehicles. Then, too, insects and diseases are less likely to be attracted to branch cuts during dormancy.

I have a couple of questions for you accompanied by a few photographs about a yellow poplar and a maple in my yard.
Q: The first question is about a yellow poplar that was here when we moved in about three years ago. It was in need of a trimming, so I did so that
winter, especially to remove a lower branch that was out of place. I know certain varieties of the species tend to grow straight up and produce a pyramidal crown later, but this tree seems pretty mature to have not done that yet. I’m wondering, is there any special pruning or anything I can do to help it spread out and start producing shade? The tree is about 20-25 feet and about 6-7 inches in diameter at the trunk. Read More

Q: How much space do I need for a backyard orchard?
Well, this depends on your purpose. A single, self-pollinating peach tree may satisfy a peach lover. Or you may be like Stuart Kennedy of Cincinnati who just planted 10 dwarf apple trees because his wife makes great pies and they want to watch their budget in these tough economic times. Stuart has also added a 2,200 sq. ft. garden, a grape vine and a pear tree as the family tries to move toward growing its own food.

Q: I’ve noticed that sometimes trees drop their twigs and leaves in the summer. Is this normal for certain species or is this an indication of a problem?
The terms for what you are seeing are “summer dormancy,” “summer leaf drop,” and “cladoptosis,” the latter meaning “a branch” and “falling.” By whatever name, what you see is a reaction to stress. Read More

Q: What trees attract honeybees?
This is a good question, especially in light of the struggle our industrious little friends are having just to exist in our ever-urbanizing world.

Q: I’ve planted some drought-tolerant species that later died during the hot summer months.
If they are listed as drought-tolerant, shouldn’t this be a guarantee against mortality in the dry period?
Trees listed as drought-tolerant are those that have genetically adapted to sites in their native habitat that regularly experience prolonged dry spells. However, all newly-planted trees can use some help from us.
