Q: We have had three English walnut trees for at least 20 years. In those years, we have had about 4 bushels of nuts from them, except for the last four years. Now, we have not had even one nut. I don’t know why. We also have pecan trees. In the last four years, they have had lots of nuts, but the nuts are dried out and no good. What is wrong with them? – […]
B. Rosie Lerner Purdue Extension Consumer Horticulture Specialist The recent Arctic blast that visited our area made for a rather dramatic leaf fall in many neighborhoods. With large quantities of leaves blowing around their yards, some people may be tempted to resort to the old-fashioned and effective method of burning. However, in addition to being illegal in many areas, leaf burning leads to air pollution and is a health and fire hazard. The smoke from […]
Q: HELP!! The bagworms are killing my trees. How can I stop them? What importance are bagworms to the environment? Do they do any good? If stripping the tree of all its nutrients is their only purpose, I’m for trying to get rid of them! Besides killing my trees, they form a strong web that allows them to cling to the side of my house, my lawn furniture, the outside grill, etc. Hope you can […]
Q. I have this smoketree that is about 10 years old. It will get to the seedy stage, but then it won’t completely bloom out. There might be two or three that will completely bloom out. Do I need more than one tree? Is there such a thing as a male and a female? Please help me get that tree to bloom. — Shirley Sitek, Knox, Ind. A. Smokebush has a rather ineffective flower, but […]
Q: I have roughly three acres of land that apparently were cow pasture before our house was built in 1985. I have been trying to reforest this property since 1988. Most of the trees and the grass have been very healthy, including a white oak that must be 150-plus years old. The varieties of trees are diverse on the property. We are only losing wild cherry, maple, ash and willow. My concern is for some […]
If you’ve ever had to work on a tree leaf collection, you no doubt included a leaf from the Indiana state tree among your samples. Also known as tulip poplar and yellow poplar, the tuliptree is actually not a poplar at all, but a member of the magnolia family known botanically as Liriodendron tulipifera. Native to most of the eastern half of the United States, the tuliptree prefers rich, moist, well-drained, loamy soil. It is found […]

Q: I hear about taking cuttings from different plants, but it has not worked for me. Please give us amateurs some pointers on when to take them and what type of soil or other medium to use. Do we keep them indoors or outdoors? – W.J. Harber, Ossian, Ind. A: This is a great time of year to take cuttings of tender plants so you can enjoy them again next growing season without having to purchase them […]

Q. We would like to establish tiger lilies along a 50-foot portion of a bank on a farm pond where grass and weeds now grow. We have lilies growing wild along our field. My questions are: Is transplanting from these wild lilies a good bet, or should we buy bulbs? When is the best time to do that? Thanks. – Steven A. Cain, Brookston, Ind. A. I think you may mean daylilies instead of tiger lilies, since […]
