Growing Redbud and Crape Myrtle from Seed and Cuttings

Eastern redbud (Cercis canadensis) and crape myrtle (Lagerstroemia) are beautiful, adaptable trees that can be propagated at home. Here's how to succeed with each.

Eastern Redbud (Cercis canadensis)

Seed Propagation

Redbud is a legume—its seeds have hard coats requiring scarification and stratification.

1. Collect pods when brown and dry in fall.
2. Remove seeds; nick each with a file or sandpaper (scarification).
3. Place in moist paper towel, seal in plastic bag, refrigerate 5–8 weeks (stratification).
4. Sow in pots; keep warm (70°F) and moist. Germination in 2–4 weeks, often sporadic.

Cutting Propagation

Difficult; softwood cuttings in early summer with rooting hormone and mist have low success. Seed is preferred.

Crape Myrtle (Lagerstroemia indica)

Seed Propagation

Easy and fast. No stratification needed.

1. Collect dry seed capsules in fall; crush to release seeds.
2. Sow on surface of moist mix; press lightly.
3. Keep at 75°F. Germination in 2–4 weeks.

Cutting Propagation

Softwood cuttings (4–6 inches) in May–June root well in 6–8 weeks with hormone and humidity. Hardwood cuttings in winter also work.

DIY Rooting Hormone (Willow Water)

Soak chopped willow stems in water for 24–48 hours. Use the liquid to dip cuttings—it contains natural rooting compounds (IBA).

Overwintering Young Plants

In Zone 5b (Maryland), keep potted seedlings in an unheated garage or sheltered spot. Water occasionally. Plant out in spring after frost.

Both trees reward the effort with years of blooms and beauty.
