ABOUT COLLIN COUNTY
OUR CRAZY WEATHER
It gets really hot in Collin County, but is also gets cold. Many people lose plants in the winter when temperatures dip below freezing. Some plants don't mind this, but all plants have a temperate at which they just cannot survive. According to the USDA Plant Hardiness Map, are in Zone 8a (or just 8 is ok) in Collin County, so check those plant tags to be sure the plant you are buying can handle a low temp of 10° F.
Similarly, become familiar with the "microclimates" that exist within your landscape. These are small pockets where climate conditions vary dramatically from surrounding areas. Gardeners often use these microclimates to their advantage in growing plants normally considered to be out of their local hardiness zone. For example, some gardeners have success overwintering Zone 9 tropical plants outdoors in North Texas by locating them against a protected, South-facing brick wall.
