Gardening Tips, Hints and Hacks June 2025

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 npsot.sa.news@gmail.com.  Be sure to include your name, fully describe the gardening tip, and possibly include an illustrative photo.

Try These Garden Hacks!

In the past year I’ve discovered the following gardening hacks:

Bobby Pin and RulerHairpins – While I’ve never mastered the art of using hairpins in an updo, I have discovered that they are handy items in the garden! I use them to encourage rooting at plant nodes for groundcovers and layering other perennials:

  • Frogfruit often has long runners that lay on top of the ground without rooting. Use a hairpin to pin the stem to the soil at a node where roots can develop. 
  • I am also experimenting with using hairpins on other fairly lightweight stems that I’d like to root through layering such as Pigeonberry and Texas Betony. I use the hairpin to pin the stem to the ground (soil, not mulch) at a promising leaf node.
  • Make sure you buy old-fashioned hairpins, not bobby pins! They come in different lengths. Found a pack of 200 (2 ¼ inch) for about $4 online (made in China). 


Box Tip for GardeningCardboard shipping boxes – 
Cardboard isn’t just for smothering Bermuda grass! It makes a great temporary “cage” for new plants (see image below). Cages help protect your new plant from the critters that frequent your yard. Since new plants get extra watering for awhile, the moist soil attracts insects, which attracts digging critters looking for insects to eat. 

  • Select a box that can easily slip over your plant with some room to spare to keep the critters from digging too close!
  • Adjust the height of the box by tucking in some or all of the flaps.
  • The box supplies some shade, but you can also use the top flaps to provide extra shade at first. 
  • Place the box over your plant, and secure it with sticks at several points so it doesn’t move around. 
  • The boxes dry out fairly quickly after a rain and are surprisingly durable. The boxes in this photo have endured 6.5 inches of rain over the past 5 days! When you’re done with caging, or need a new box, just pitch the old one into your green can! 


Salad bags –
 Did you know your bagged salad greens come in a highly engineered bag to keep those greens fresh? If you occasionally take cuttings and don’t have access to a greenhouse and misting table, I’ve found that simply popping an empty salad bag over the 4” pot between mistings helps maintain the humidity level around the cutting, while allowing the plant to breathe, which greatly increased my success rate! Of course, cuttings should not be placed in direct sun while roots are establishing.

About the Region

Fall Symposium 2025 Logo - Teach for the Future

Salado, the location of our Fall 2025 Symposium, lies at the intersection of two ecoregions: the Edwards Plateau (Limestone Cut Plain) and Blackland Prairie (Northern Blackland Prairie).

The Edwards Plateau area is also called the Hill Country; however, this general term covers a much larger area extending farther north. Spring-fed creeks are found throughout the region; deep limestone canyons, rivers, and lakes (reservoirs) are common. Ashe juniper is perhaps the most common woody species found throughout the region. Additional woody species include various species of oak, with live oak (Quercus fusiformis) being the most common. Sycamores (Platanus occidentalis) and bald cypress (Taxodium distichum) border waterways. This area is well known for its spring wildflower displays, though they may be viewed in spring, late summer, and fall, as well. According to Texas Parks and Wildlife, average annual rainfall in the Edwards Plateau ranges from 15 to 34 inches.

The Blackland Prairie extends from the Red River south to San Antonio, bordered on the west by the Edwards Plateau and the Cross Timbers, and on the east by the Post Oak Savannah. Annual rainfall averages 30 to 40 inches, with higher averages to the east. This region is dominated by prairie species. The most common grass species include little bluestem (Schizachyrium scoparium) and Indian grass (Sorghastrum nutans) in the uplands and switchgrass (Panicum virgatum) in the riparian areas and drainages. Common herbaceous flowering plants include salvias, penstemons, and silphiums. This area has suffered greatly from overgrazing and agricultural use. Few intact areas remain, though many of the plants can be found along county roadsides throughout the region.

Our four host chapters (New Braunfels, Lindheimer, Guadalupe, and the Hill Country chapters) are located in one or both of the ecoregions above. However, the eastern portion of Guadalupe County also falls within the Post Oak Savanna ecoregion. Annual rainfall averages 35 to 45 inches, with higher averages to the east. A wide variety of hardwood trees are found, including several species of oaks, elms, and in the Bastrop area, loblolly pine (Pinus taeda). Grasses and forbs dominate in the open savannas, with most common grass being little bluestem. Ranching, agriculture, and fire suppression have allowed woody species to encroach on the once-open savannas.
