Turk’s cap (Malvaviscus arboreus) is easy to propagate in North Texas. Stem cuttings are the fastest and most reliable method.
Stem cuttings—best method
Best timing: April through September. Late summer cuttings also work if you protect the young plants during winter.
- Cut a healthy, nonflowering stem about 4–6 inches long.
- Make the cut just below a leaf node.
- Remove flowers, buds, and the leaves from the lower half.
- Leave two or three leaves at the top. Cut large leaves in half to reduce water loss.
- Optional but helpful: dip the bottom in rooting hormone containing approximately 0.1%–0.3% IBA.
- Insert 1½–2 inches into a moist mixture of:
- 50% perlite
- 50% peat moss or coco coir
- Water thoroughly and let excess water drain.
- Cover loosely with a clear plastic bag or humidity dome. Keep the plastic from touching the leaves.
- Place in bright shade—never hot afternoon sun.
- Keep the mixture slightly moist, but not soggy.
Roots usually begin forming in three to six weeks. Gently tug the cutting; resistance usually means roots have formed. Gradually remove the humidity cover over several days, then transplant into regular potting soil.
Rooting directly in water
Turk’s cap often roots in water, although soil-grown roots generally transplant more successfully.
- Place a 4–6-inch cutting in water with the lower leaves removed.
- Keep one or two nodes underwater.
- Change the water every few days.
- Pot it when the roots are approximately 1–2 inches long.
Division or digging suckers
Established plants frequently produce shoots around their base.
- Dig around a young shoot in early spring or fall.
- Locate and cut the connecting underground root.
- Lift the shoot with as many roots as possible.
- Replant immediately and keep it watered for several weeks.
This is usually the quickest way to produce a substantial new plant.
Growing from seed
Collect the red fruits after they mature and soften. Remove and clean the seeds. Seeds germinate more reliably if you lightly scratch the seed coat with sandpaper and soak them in warm water overnight. Plant about ¼ inch deep, keep warm—roughly 70–80°F—and allow several weeks for germination.
For Garland’s climate, I would take several cuttings between now and early September, overwinter them in pots somewhere protected from hard freezes, and plant them outside next spring.
