Cynthia Beacom, Hunt County Master Gardener, says gardening is an excellent activity for people who are forced to stay home because of the coronavirus. Gardening can burn up to 300 calories an hour. On another topic, Cynthia says crepe myrtle bark scale is becoming a problem. It is not fatal to the trees, but reduces their blooms and covers the trunks with a dark scaly substance. She explains the treatment for the disease.
