Q. I have four large trees in my backyard, causing quite a bit of shade. There is a pine, an oak, ash an and a maple. The lawn is too dark for grass, and the quantity of leaves is overwhelming in the fall. I’d like to take down one tree but can’t decide which one. I don’t feel particularly attached to any, although the pine screens the neighbor’s yard somewhat. All seem to be roughly […]
Q. I have a problem weed. It is rubbery with teardrop-shaped leaves. I’ve noticed it will reroot itself when thrown on the ground. It is very hard to kill. In fact, I think it thrives on Round-Up. Can you help? — Teresa Allman, United REMC A. The green, rubbery leaves of purslane are one-half to 1.5 inches long on thick, reddish-green stems. It sometimes bears yellow flowers, and the seeds are borne in a small […]
Q. How deep should mulch be at the base of a tree? I usually put a light coating around the trunk, in a circle, but I see some professional landscapers making big mounds. Does that keep more moisture in? — Shirley North, South Bend, Ind. A. Generally, a layer of mulch should be 3-6 inches deep, not a volcanic pile like you see around some trees! Even at this reduced depth, it should be pulled […]
Q. My iris were beautiful with lots of flower buds this year, but just about the time they were in full bloom, the heavy rains came and knocked all the tall, blooming stems to the ground. Is there any way to prevent this? — Wendy Lacrosse, Fort Wayne, Ind. A. Many plants can be pinched early in the season to increase branching and reduce lodging, which is the fancy word for crashing to the ground. […]
Q. I have 6-year-old flowering dogwood trees that have never bloomed. The foliage looks healthy each year. What do you suggest? — Carrie Ehresman, West Lafayette, Ind. A. It does take a dogwood a few years to become established, and we don’t make the job any easier for them. Drive through Southern Indiana and notice where the dogwoods are growing. They’re nestled into the edge of the woods where they receive shade and protection from […]
Q. I have a small greenhouse that I use to winter over plants and to start new ones from seed in the spring. Each year I get whiteflies. I have bought commercial sprays from lawn and garden departments, but even with repeated applications, the whiteflies seem to persist. What is the best method to rid my greenhouse of these pests? Is there a prevention I should implement? Are there certain plants that attract whiteflies? — […]
Q. My honeysuckle is pretty wild looking. Dare I cut it down this time of year, or should I just grin and bear it? — Jean Phillips, Lafayette, Ind. A. You won’t kill it if you prune it now, but the cuts are areas that could dry out during winter. It’s best to wait until spring, just before it leafs out, if you’re going to do drastic pruning. If you just want to tip it back a […]
Q. I am a resident of Orange County, just outside of Paoli. I recently noticed that my red horse chestnut tree, which had previously lost all of its leaves due to drought, has sprouted several red flowers. Some leaves are coming out and MANY buds are swelling. Many buds are not swelling, and I hope they stay that way. The drought tricked the tree into early dormancy, and now the recent rains have awakened the tree […]
Q. We need your expert help concerning our Stanley plum tree. We planted the tree four years ago. The catalog said it is self-pollinating. One year we had two plums. Another year we had none. This year, I found 10 on the ground. All were green and small. What is wrong? The closest other tree is an old persimmon, and it is always loaded with fruit. Do we need fertilizer? If yes, what kind? Did we […]
