Crape Myrtle Bark Scale’s Enemy

Parking at a local restaurant today, I noticed the blackened trunks of some topped crape myrtles – the tell-tale sign they were infested with crape myrtle bark scale. This relatively new pest to the U.S. has been rapidly spreading across the south. A horticulture friend commented he saw infested crape myrtles at the new mall on the south side of town. I checked them out, and while the trunks were blackened, there was no sign of living scale. These scales are bright white, and when squished, they ooze… Read More →

Avoid Introducing Nematodes to Potted Plants

While planting pansies and some other cool season annuals in pots, planters and in flower beds recently, I was reminded about nematodes. If you are unfamiliar with nematodes, they are microscopic roundworms that live in the soil. Some nematodes are beneficial, and several are plant pests. The bad types feed on roots and other plant tissues, disrupting normal plant functions. One of the worst ones is called root-knot nematode. I first realized I had nematodes several years ago when I planted tomatoes in what I thought would be… Read More →

Put Your Garden to Bed and Get Ready for Spring

This is the time of year to put your flower and vegetable garden to bed, and start getting ready for your spring garden. Now that we’ve had some hard freezes, annual flowers and warm-season vegetables are finished and can be removed from the garden. Cut back browned tops of herbaceous perennials like salvias, phlox, lantana, cuphea, cannas, and others. Chop them up and throw them in the compost pile. I like to leave until spring the dried coneflower seedheads for finches to feed upon. Ornamental grasses can be… Read More →
