Cyclamen (Cyclamen persicum) This species of cyclamen is a popular plant with florists, and often is called the “Florist’s cyclamen.” The plant is a tuberous perennial with heart-shaped leaves, 1 to 5-1/2 inches long, deep green in color. The leaves often have a silver-marbled tint on top of the leaf and pale or purplish green on the bottom of the leaf. It produces sweet-scented pink, red, or white flowers, 1/2 to 3/4 inches or more […]
Amaryllis (Hippeastrum hybrids) The Hippeastrum hybrids produce clusters of huge red, pink, salmon, white and bicolor trumpet-shaped flowers atop tall slender stalks. The leaves and flowers arise from a large bulb, often resulting in 8-12 flowers per bulb. Amaryllis can be used as a potted plant for holiday decorating. They also make lovely cut flowers for arrangements. When selecting bulbs make sure the bulb feels firm and full. If growth has started, check to see […]
Q. After many years of growing pumpkins successfully (I do rotate the growing site), the past four years have been disastrous. Just before the buds begin to truly form, the plants collapse. There seems to be no sign of a squash borer. I would appreciate your advice. — Nancy M. A. It is difficult to say for sure without more specific symptoms, such as leaf or fruit spots, discoloration, etc. Squash vine borer is a […]

I’ve been answering Indiana gardening questions since 1984, when I joined the Purdue University Cooperative Extension Service. I grew up in Chicago, Ill., and was an urban gardener for most of my life but now live on five partly wooded acres heavily populated with critters and insects. I’ve never seen such a diverse array of wildlife all in […]
Q. I have several peonies that are 80-plus years old located in an old farmstead. I would like to transplant them to a more suitable area. What would be the best way to transplant them? What do I need to do as far as fertilizer and water needs after the plants are moved. — Rich Unger, Terre Haute, Ind. A. Peonies are incredibly tough plants! Select a location for the transplants where they’ll have good […]
Q. I have some questions about a ‘Rose of Sharon’ bush I have, which was damaged in the ice storm that we had last winter. I was wondering when would be a good time to trim it, how far back should it be trimmed and how often. Thank you ever so much. — Barbara Huse A. Since plants bloom on new growth, shaping or pruning can be done at any time. Pruning in late winter […]
Q. I have a rhododendron bush that looks like it is getting rust on the leaves. I think perhaps something is eating on it. What should I use to control this? Thank you. — Joan Wininger A. It’s important to determine if the rust is a problem or a natural occurrence. Many rhododendrons have a natural, rusty-brown, scaly appearance, particularly on the underside of the leaf. Rhododendrons may also be showing leaf scorch at this […]
