Gardening Tips, Hints and Hacks July 2023

If you’ve been gardening for any amount of time, you have probably discovered practical gardening practices that work for you here in Central Texas.  We’d love for you to share them with us!  In coming newsletters, we’ll select and share one or two submissions.  Please help us make this new monthly feature a success by sending your submissions to sanantonio@npsot.org.  Be sure to include your name, fully describe the gardening tip, and possibly include an illustrative photo.

Time To Prune Your Native Perennials

Early summer is the time to prune! So many plants are growing VERY well right now from all our rain this spring. And as much as I don’t mind things growing a bit wild, even I’m like WOWSERS. It’s time to get pruning! 

Plants benefit from being trimmed, even if they have flowers. They’re just going to give you more flowers and be more bushy, healthier, and prettier. 

Some plants that are fall bloomers (like Frostweed) should get a heavy prune so they aren’t too tall and become top heavy with their blooms. Here’s a list of things you should be pruning now.

  • Frostweed: cut by a least 1/2 of whatever its height is currently is. (I cut mine back to 8”)
  • Tall Goldenrod: Cut 1/2 way its current height.
  • Turk’s Cap : Cut 1/4-1/2 its current height. (I cut back to 8”)
  • Maximilian Sunflowers: Cut by 1/2.
  • Autumn Sage: 1/4 trim all around
  • Texas Fall Aster: Cut back 1/4 and long and leggy stems.
  • Mistflowers: 1/2 their current height.
  • Flame Acanthus: anything leggy (or to your desired height/width)
  • ALL NON-NATIVE MILKWEED: This mimics our native milkweed going dormant for summer and will grow back with OE clean leaves/flowers for Fall migration.

About the Region

2026 Fall Symposium Logo

This low-elevations region of Texas extends inland from the barrier islands, about 60 or so miles, and stretches from Brownsville to Louisiana. In total, it covers about 9.5 million acres, with a high point of 150 feet in elevation. More than 1000 species of plants can be found in this region. On the southern end, species more common in Mexico (such as Sabal mexicana) and Central America occur.

The barrier islands provide us with dune systems, and clay flats to the inland side, which have species found in these areas alone. Many plants here, such as Ipomoea pes-caprae (beach morning glory), can be found throughout tropical regions of the globe. I’ve encountered the same species on the beaches of Guam.

Once inland, vast marshes and wet prairies occur. Occasionally, oak (Quercus fusiformis) groves can be found. Common grasses include species of Bothriochloa, Paspalum, and Sporobolus; eastern gamagrass (Tripsacum dactyloides); and switchgrass (Panicum species). Many rivers and creeks cut through the Gulf Prairies, and along these riparian areas various species of trees, Sabal minor, and other plants adapted to clay soils can be found. Due to overgrazing, farming, and fire suppression, woody species such as mesquite (Prosopis glandulosa) and huisache (Acacia farnesiana), and invasive species such as chinaberry (Melia azedarach), Brazilian pepper (Schinus terebinthifolius), and Chinese tallow (Sapium sebiferum) have increased and displaced our native flora.
