Texas Milkweed

Year-round

Texas milkweed is a low, tidy perennial that likes it lean and dry. Once it settles in around Dallas it needs almost no fuss. The biggest mistake is being too kind with the hose.

• Give it fast draining soil and full sun to a little afternoon shade. Heavy clay that stays wet is the main thing that kills it, so plant on a slope or a raised bed and mix in gravel or decomposed granite if your Blackland Prairie soil holds water.
• Water regularly the first season to get roots down, then back way off. Once established it wants deep, infrequent soaks and can rot if the crown stays soggy.
• Keep a thin gravel or leaf mulch a couple inches back from the stems, not piled against them, so the base stays dry.
• Leave the seed pods if you want more plants. It self sows lightly, and you can pull any volunteers you do not want in spring.

Fall

In fall the plant winds down and pods ripen. You mostly leave it alone. If a front yard needs to look kept, a light tidy of flopped stems reads as intentional.

• Let the seed pods mature and split so seed can drop or be collected. This is the natural way it makes more plants.
• Ease off watering as nights cool. The plant is heading toward dormancy and does not want wet feet going into winter.
• If a stem has flopped over a walkway or into the lawn, trim just that one back rather than cutting the whole plant.

Reads as intentional and helps avoid a violation letter: in a front yard, snipping the few stems that have flopped onto a path or lawn keeps the planting looking cared for while the rest ripens seed.

Winter

This is a native perennial that dies back on its own over Dallas winters. You can leave the dry stems standing or cut them for a cleaner front-yard look.

• The top growth browns out and goes dormant after the first hard freezes. The roots are fine and will resprout in spring.
• Leaving a few standing stems gives cover for overwintering insects, but this is optional.
• Give it no supplemental water in winter unless there is a long warm dry spell. A dormant, dry crown resists rot best.

Reads as intentional and helps avoid a violation letter: if bare brown stems look messy from the curb, cutting the dead top growth down to a few inches now gives a clean, deliberate winter silhouette until spring growth returns.

Spring

Spring is the reset. Cut last year's dead stems to the ground as new growth appears at the base, and let new plants get going with a little water.

• Once you see fresh basal shoots, usually March in the Dallas area, cut the old brown stems down to a few inches with clean pruners.
• If you set out a new plant this spring, water it every few days until it roots, then start stretching the gaps between waterings.
• Thin or move any self sown seedlings now while they are small and easy to lift.

Summer

This is bloom time, June through August. Dallas summers are hot and dry, which suits it fine. Water deeply but rarely and let it flower.

• Water a deep soak only when the soil is dry several inches down. In a normal Dallas summer that is every week or two at most for an established plant.
• Expect white flower clusters through the heat. You can leave them for pollinators or snip a few spent heads if you want a neater look.
• Do not fertilize or overwater to force growth. Lean and dry is what keeps this plant healthy and standing upright.
