How Do I Take Care of a Heather Plant in Texas?


Mexican heather plants thrive in the hot Texas climate and are appreciated by many gardeners for their relative low maintenance. Their leaves have a soft, fine texture and create dense foliage in a shrub-like formation. Mexican heather plants reach 3 feet in diameter and about 2 feet tall. Its small, purple flowers attract butterflies and bloom throughout spring and summer. Mexican heather cannot survive freezing temperatures but occasionally makes it through the mild, Texas winters.

Step 1

Plant Mexican heather in an area with partial shade for protection from high heat. Though Mexican heather can tolerate full sun, its leaves will almost certainly fade to a light shade of green in the hot Texas summer. Select an area with fertile, well-draining soil.

Step 2

Space each plant at least 2 feet apart. This will provide enough room for growth and air circulation without leaving any noticeable gaps between your plants.

Step 3

Water Mexican heather on a daily basis, especially during the dry Texas summers where temperatures regularly top 90 degrees F. Reduce watering to once every 1 to 2 weeks in the winter.

Step 4

Fertilize your plant with a slow-release formula in late winter, spring and summer. Follow the package directions so as not to damage your plant.

Step 5

Trim two-thirds of the foliage off your plant in late fall. Mexican heather cannot survive freezing temperatures, but may come back in spring after a mild Texas winter.
