The Q&A Archives: Plants Resistant to Texas Root Rot

Question: Is there any way to eliminate Cotton Root Rot from a flower bed? (from Arlington, Texas)

Answer: The nemesis of Texas gardeners and farmers. No other disease attacks more kinds of plants that Texas Root Rot. And few diseases are harder to control. The best approach is to stick with resistant plants such as sweet alyssum, basil, bee-balm, collinsia, calla lily, California poppy, candytuft, canna, cucumber, cyclamen, daffodil, deutzia, dill, fennel, ferns, foxglove, gypsophila, hackberry, hyacinth, iris, lily, mints, mimulus, muskmelon, mustard, nasturtium, oak, osage-orange, oxalis, palms, pansy,petunia, phlox, pinks, pomegranate, poppy, portulaca, primorse, pumpkin, sage, verbena, violet, wallflower, watermelon, yucca, and zinnia. Note that most annuals are winter growers (when the fungus is at its weakest). Other annuals can be tried duringthe cool months as well. When planting large beds, it's a good idea to mix susceptible plants with the above resistant plants. Also develop a crop-rotation scheme for vegetable gardens.
