Q. Some years our potatoes and beets have a pitting or scabbing on the surface. It makes them very unappealing to want to eat them. I think they are OK on the inside. What causes this? A. While it is difficult to diagnose with certainty without seeing samples, there is a disease commonly called potato scab that affects both potatoes and beets. Other root crops, such as radish, rutabaga, turnip, carrot and parsnips, are also […]
Q. I enjoy reading your column every month in our Daviess-Martin County REMC Electric/Consumer Magazine. I have learned so much about flower gardening and share several articles with friends. My Amish friends in the Montgomery community have mentioned a “Busy Lizzy” plant that sounds similar to a pink begonia, since it was planted in shade and then taken in for the cold weather. They are no longer able to find any seeds or plants. It […]
Q. Could you tell me what kind of weed is creeping through my lawn and flowerbeds? It has scalloped edges on the leaves and pretty blue flowers. The leaves have a strong smell. I have tried all kinds of weed killer on it; I think it makes it grow! A. You and most every gardener in Indiana are doing battle with the common perennial weed called ground ivy, aka creeping Charlie, a member of the […]
Q. I have been collecting red and orange Canna seeds this year from plants produced by bulbs at least 3 years old. Can these seeds be propagated? If so, what steps should I take? A. Canna is more typically propagated by dividing the rhizomes (thick, underground stems) so that each new section has at least one healthy bud that will become the new shoot. They can be propagated by seed, but keep in mind that […]
We continue to receive numerous inquiries about bagworms on landscape plants, especially evergreens. Since we’ve addressed this issue several times over the last few years, I won’t take the time to repeat the information here, but you can find the answers to most of your questions from the Purdue Extension entomology specialists online at http://www.ppdl.purdue.edu/PPDL/weeklypics/7-29-02-1.html and http://extension.entm.purdue.edu/publications/E-27.pdf. Q. I have learned about this dreadful stuff called artillery or shotgun fungus the hard way — namely by having it […]
Q. We discovered fire blight on one of our apple trees this summer. We cut all the branches with symptoms (withered leaves and the crook at the end) and burned them. We have seen no sign of any further damage. Do we still need to spray next spring as directed by the product we bought from our local nursery? A. Fireblight is a bacterial disease that affects over 70 members of the Rose Family (Rosaceae), […]
Q. I have a 2-acre yard that is filled with Ash trees. For years, I have had the problem of small trees or limbs growing from the base of the tree. I call them “suckers.” I have cut them off right to the tree base, but they keep coming back. Some of my trees have what looks like a bush surrounding it. This happens with old trees and young trees. What causes this and how […]
Q. I wrote you last year about my apricot tree having no fruit for two years. You wrote that it’s not unusual. Now, a third year had lots of blossoms but no fruit again. What can I do to get fruit? A. Lack of fruiting is to be expected for apricots in our area of the Midwest most years, and this year is no exception. Apricots are about the earliest to bloom of the fruit […]
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 […]
Q. I am wondering what causes a layer of stiff, hard white tissue under the skin of some of my tomatoes. It only affects a few. The inside of the tomato is fine after this is peeled off. Is there something in the soil? We have a lot of clay soil here in Clay County, Ind. I use Fast Start when setting them but no fertilizer after that. A. Sounds like you’re describing a common disorder […]
