Author, speaker and creative gardener Shawna Coronado turns blank fences, balconies, and patios into vertical gardens for food, beauty, spiritual comfort, and pollinators. At the American Botanical Council’s gorgeous gardens against an historic house, discover easy-to-grow plants with medicinal benefits to promote good health or to heal what ails you. Spice up your drought-defiant garden with the culinary and healing evergreen oregano. And in backyard basics, we learn to make our own hypertufa containers.

Question of the Week

Do sotols die after blooming?

In late spring, our various succulents send up fantastic blooms!  It’s easy to confuse all of the various beautiful desert plants that are making their way into our Central Texas landscapes these days.  Yuccas, agaves, sotols, nolinas, and others all have similarities.

And one of those similarities is a skyward-shooting bloom stalk.  One of those groups of desert plants, the agaves, DO die after blooming in many cases, depending on species.

Other desert species, including Dasylirion, which are the sotols, don’t.  All of these desert plants may take many weeks, or even months, to form their glorious bloom stalk, which start to emerge in early spring and may not be fully spent until late summer or early fall.

Cutting out the bloom stalk, after it’s seen its better days, can be challenging.  You’ll need some heavy duty gloves to protect your hands from the sharply toothed margins of the sotol’s leaves.  And you’ll need a small hand saw, like you might use to cut small tree branches.  It would be very challenging to get a pair of pruning shears down into the space where you’d need to make the cut, and you’d also be surprised at how hard and thick that bloom stalk may be.

As with pruning tree limbs, I recommend you cut the top off first, to remove the weight.  Then you won’t have to worry about the potential of cutting halfway through the bloom stalk and then it toppling over and causing damage.

Plant of the Week



Oregano comes in all different types, varieties and cultivars. All are very drought tough and all require good drainage. Oregano’s so easy to grow, even in a container, that you’ll never need to purchase it in the produce section ever again! Or buy dried out oregano! On top of that, it makes a great groundcover and in fact, without an intervention, oregano will creep steadily across any garden bed that you plant it in. much the same as many of its other minty relatives. There’s no reason to isolate it in an official herb bed; include it as a groundcover to border walkways or accent beds. Oregano spreads by rhizomes, and so it’s very easy to dig up a hunk of it and transplant it to another area of your garden, or to give to friends. Some cultivars get much taller than others, so be sure to get the right one for your space. Full sun is great, but a little shade is fine too. Oregano will do fine on once a week irrigation and performs best with a little organic matter in the soil. In warmer winters it may remain evergreen but will still need to be sheared back all the way to the ground to encourage new growth in early spring. Some cultivars flower easily, while others rarely do. But this plant is grown for its leaves, so you really don’t want it to flower anyway. After vigorous spring growth, it’s a good idea to shear oregano back quite a bit, otherwise it tends to get leggy and flop over, which doesn’t hurt anything, it just doesn’t look too attractive.

Backyard Basics

Making Hypertufa Containers

In Backyard Basics this week, Trisha and Collen Dieter show how to make creative pots for plants using hypertufa, a lightweight composite material bound with cement. Additional tips from the two can be found here.
