Q A couple of years ago I bought a Bougainvillea in bloom. It was very nice and at the end of season I brought it into my garage. The first thing it did was lose all leaves and I thought it was dying. However, I would scratch the surface of branches and always found living green. I almost gave up but pruned it to about 6 inches high and took it back outside in the sunshine when weather permitted. The result was great — it grew to about 6 feet in diameter and had many blooms.

A If you don't have space indoors or have access to a greenhouse, the key to overwintering tropical blooming plants is to prevent them from freezing. They usually defoliate or die back in the process of surviving with little to no light and low temperatures in a garage, but they can survive. Pruning them back to live wood and moving them out is by far the best thing you can do in the spring. Even plants that don't die back need to be pruned since bougainvillea blooms on the new growth. If you leave older woody stems, they won't grow much and then you will see fewer blooms. Repotting can help with some tropical plants. Do keep in mind that bougainvillea does tend to bloom best if it is slightly pot-bound, but if it is too root-bound then it makes it difficult to keep watered during the summer.

Q I planted zinnias at my home garden in west Little Rock and they did fine. I also planted them at my garden space at Pulaski County Garden Center at Two Rivers Park. These, however, developed large black spots on the leaves and the flowers did not fare well. Any solution for next year?

A My guess is that your zinnias at the park suffered from alternaria blight which causes brown blotches on the leaves. Unfortunately the fungus can persist in the soil as well as the seeds, so don't use any saved seeds from that location in your home garden. I would also recommend planting some other annual for the next couple of years at the park.

Q I have two dogwood trees which are probably about 30 years old. Last spring I noticed there were not many blooms on them. This fall I didn't see any red berries. I've attached 2 pictures of one of them, close-up and distant [reader sent photos]. Is it just old? I don't recall seeing dogwood trees without red berries.

A Berries will only occur if there were flowers, so if the blooms were sparse last spring, you won't see many berries this fall. From the close-up picture it looks like your tree is loaded with flower buds for this spring, so that is good news. For the distant picture, your tree is really quite small -- in height and stature, if it is 30 years old. A mature dogwood tree can be 15-20 feet tall with a 20-30 foot spread. Your trunk is narrow with very few branches. Has it always been this way or was it pruned?

Q Please identify the grass-like plant in this photo [reader sent photo]. It was seen in Paragould. I understand you have retired and I wish you the best in your retirement. I do hope you will continue to write articles for the Arkansas Democrat-Gazette.

A The grass in the picture is purple muhly grass -- one of the most popular ornamental grasses on the market now. The most common color for the airy blooms is a pinkish purple but they now have a white flowered form as well. It is a more compact ornamental grass and quite attractive. And thank you for your well wishes. I retired from the UA Extension Service on Jan. 2, but I will keep writing for the Democrat-Gazette.
