Q: I’ve attached pictures of the only tree we have on our property. Because it is our only tree, I am deeply concerned with the possibilities of irreparable damage to it. As you can see, one of the branches broke off during a November windstorm. Unfortunately, that left a bare gap on the trunk. Please let me know how to treat this damaged area so no further damage is done to it and tell me […]
Topping a tree is an all-too-common practice among homeowners, particularly when their trees become too tall and pose a possible threat to the house or overhead power lines. Some have the trees topped because they believe, or are led to believe, that topping is a good pruning practice. Some situations obviously require the removal of large limbs for the sake of safety. But topping is a drastic step that ultimately endangers the tree’s life. Removing […]
Q. Can you tell me what kind of tree this is? They were planted near our community lake 25 years ago. K.M., Indianapolis A. This is a honey locust tree, known botanically as Gleditsia triacanthos. The species is native to the eastern US. It has large seed pods and trunks that are armed with wicked thorns. Fortunately, most plants sold for landscape specimens are cultivars that are both seedless and thornless. But even these improved […]
Q: We have 5.5 acres with several hundred white pines, 7 blue spruce, and 2 red pines. Several of the blue spruce are dying. Several years ago, two started dying from the bottom up. We put evergreen spikes around them, and after a year or so they came back to normal. Presently some of the large ones are now dying from the bottom to the top. We put spikes around two large and one small, […]
Q. I saw these holes in my tree and am wondering what they are from. This tree is the only one I have seen them on. – M.S., Chesterton Some species of woodpeckers cause large holes in tree trunks. A. The holes are likely from woodpecker injury, but the tree may have some other issues. Has the tree been in a state of decline for a while? Perhaps branch dieback, leaf drop or other symptoms? […]
Q. I am wondering what you might know about the small “red cedar trees” that seem to be invading fencerows and highways, especially U.S. 31 north of Kokomo. I think a column from you would be worthwhile, since I can`t seem to get my neighbors to control the “pretty little trees,” which are much like Canadian thistle and kudzu. — E.W., Kokomo A. The eastern red cedar is a juniper, rather than a true cedar. Known […]
Q. I have a yucca tree that is 5-6 years old. What was a small plant has become a mature tree. I transplanted my yucca to a larger pot last summer. There was a significant explosion in growth. If you look at the picture you can see the growth. Unfortunately, it suffered through this past winter indoors. Much of the new growth witnessed last year is gone. Please see the attached photo — I think it […]
If you’ve ever had to work on a tree leaf collection, no doubt you included a leaf from Indiana’s state tree. Also known as tulip poplar and yellow poplar, the tuliptree is actually not a poplar at all. It is a member of the magnolia family known botanically as Liriodendron tulipifera. The tuliptree is native to most of the eastern half of the United States and prefers rich, moist, well-drained, loamy soil. It is found throughout […]
Q. I have a maple tree (it is either an ‘October Glory’ or ‘Autumn Blaze’) that has (what I assume to be) a rather large sucker at the bottom. The diameter of the sucker is about 2 inches, and the tree trunk is 7 inches in diameter. I have attached pictures of it from different angles. I would like to know if it is OK to remove it? I’ve read quite a bit about these […]
Q. I have some leaves from a tree I would like to identify. It is roughly 8 to 12 inches in diameter and fairly tall. The leaves are alternating with lengths of 1.5 to 2 inches long. The leaf stalks are all really short compared to the leaf length. Can you identify? – M.R., Brookville, Indiana A. This appears to be Ulmus parvifolia – common name Chinese elm or lacebark elm. This species is quite […]
