Style up, color up and eat up with companionable edibles and ornamentals. Adelante Landscape designer Cheryl Beesley and author of Landscaping with Edible Plants in Texas mingles good taste with tasteful design. Trisha Shirey grows tasty and nutritious microgreens—mini-gardens that the kids will love. Daphne throws cheery annual calendula into the pretty, delicious winter garden mix and explains why we really can’t alter our alkaline soil pH.  On tour, Linda Peterson matched a contemporary, energy-efficient house and serene courtyard with equally resourceful plants.

On Tour

Contemporary Water-Wise Garden

Linda and Carl Peterson wanted an intrinsic house and garden bond when they built their energy efficient home, serene outdoor living courtyard, and patio gardens.  To conserve water in their new landscape, Linda paired drought-tough structural evergreens with softer perennials that attract pollinators. With plants and clever design, she engaged privacy from close-up neighbors.

Question of the Week

Can we change our soil pH from alkaline to more acidic?

What is alkaline soil vs. acidic soil and how does it matter to what we grow? AND, can we really alter our pH enough to make a difference?

The bottom line when it comes to soil is, like my grandmother used to say, “Dance with the one who brung ya.” Or, “love the one you’re with,” or any number of other adages.

Yes, there are ways to change the pH of your soil, but those methods don’t last, creating a constant battle of the wills that not only you will not win, but you’ll also waste a lot of time, money and effort along the way.

Our soil in Central Texas is on the alkaline side, and lowering the pH of alkaline soil is more challenging than raising the pH of acidic soil. Gardeners in the eastern half of the U.S., who have acidic soil, often use lime to increase the pH, but we don’t have a similar tool for easily lowering the pH.

Although amending with sulfur can acidify soil, the effects are very short-lived, and so, aren’t the best use of time or resources. If you have acid-loving plants such as hydrangeas, it would be best to keep them in a container, where you can manage and alter the soil and its pH more easily.

The fact that our soil is alkaline here in Central Texas is why we can’t successfully grow many of the plants that we might like to, like camellias, many types of pine trees, and even blueberries.

So the best answer to soil pH is to plant species that can grow in our native soil without any problems. Plants that are native to our region, of course, would be most appropriate, but also, plants that are adaptable to our soil type. There are certain plant nutrients, such as iron, that are much less available at higher pH, and many plants struggle with those lower levels of elements that are essential to their growth and development. Other species, those that have evolved in a certain region along with the soil, are much better at coping.

Plant of the Week

Calendula Flower and DIY Salve

Calendula Flower and DIY Salve

Although this edible flower is an annual and will need to be replanted each year, it's well worth the time and effort. We rarely focus as much attention on our winter gardens as we do in the summer, but this little easy-care plant brings spring cheer to dreary winter days. The vibrant yellow or orange flowers are attractive to bees and hummingbirds when they start to arrive with warmer weather, when flowers on other spring blooming plants may not yet be developed. Bee on calendula winter annual Central Texas Gardener Plant calendula in full sun in well-drained soil, and don't overwater. It easily spreads from seed, so be sure to deadhead if you want to contain it to one spot. Those dried seed heads can be saved until next winter, when you can easily sow them in the garden. Yellow calendula A small plant, getting only about 18 inches tall and less than a foot wide, calendula makes a lovely addition to beds along borders and walkways, where its cheery disposition may be best enjoyed. Harvest the petals to add to salads, make soothing teas, and dry for potpourri. dried calendula flowers Learn more with Carla Crownover and to make a calendula salve and potpourri.
