Located just to the south of the Houston Metroplex, Brazoria County is nestled next to the shores of the warm Gulf of Mexico. This region enjoys a mild temperate climate, with hints of a subtropical one. You can grow many palms, camellias, azaleas and Texas native plants as well as an array of roses, summer bulbs, tasty vegetable crops, flowering annuals and perennials across the calendar year.
What Gardening Zones Am I Located Within?
Brazoria County sits in U.S. Department of Agriculture winter hardiness zone 9, where winter low temperatures, on average, range between 20 and 30 degrees Fahrenheit. Some publications place the county in zone 9a, which is the chiller half of the zone, where winter lows typically range between 20 and 25 degrees Fahrenheit. The American Horticultural Society places Brazoria County in heat zone 9--between 120 and 150 days of temperatures above 86 degrees Fahrenheit in summer. Nearer the Gulf Coast or lower Galveston Bay, there are slightly fewer hot days. Finally, the county is also placed into Sunset climate zone 28. This zone is dubbed "Northern Florida and the Gulf Coast."
What Lawn is Best?
The humid, hot summers with rainfall and mild winters allow you to choose primarily from two turf grass species. St. Augustine grass is a sound choice if you have an irrigation system or rainfall is reliable, whereas in drier soil or unirrigated landscapes, Bermuda grass may be a better option.
What is the Growing Season?
Brazoria County enjoys a long growing season of about 300 days, even longer if winter frost is delayed. Occasionally, perhaps once or twice a decade, an unusually cold air mass from the Arctic makes it all the way to the Gulf Coast, dropping temps briefly into the low teens, which can severely damage or kill subtropical plants. With the long growing season and brutally hot summer, the growing season for vegetables or annual flowers is divided into two time-frames: February to June and September to December (or first frost). Cool- and warm-season plants are sown or planted accordingly, often permitting two crop cycles each year.
Where Can I Go for More Gardening Help?
Horticultural professionals as well as Master Gardeners can be contacted at the country extension office, a governmental entity that provides research-based information from Texas A&M University. Located in Angleton, you can speak with agents, pick up print literature or visit the demonstration gardens. There are also gardens displaying tropical plants, vegetables and a trial rose bed.
