How to grow it

PLANTING: Open your Seeds In A Cup kit. Fill your container with the provided growing medium. Sprinkle seeds on the surface and press lightly — barely cover with medium. Mist thoroughly. Place in a warm, bright location (70-80°F) or under a grow light for 14-16 hours/day. No stratification needed.

GERMINATION CARE: Keep soil moist. Germination occurs in 14-21 days. Crepe Myrtle seeds are tiny — seedlings will be small at first. Provide maximum light.

SEEDLING CARE: When seedlings have 3-4 true leaves, transplant to individual larger pots. Provide full sun. Plant outdoors in USDA Zones 7-9 in spring after all frost danger has passed. Crepe Myrtles bloom on new wood — no pruning required for flowering, but light shaping is fine.

Frequently Asked Questions

What are the germination requirements for Crape Myrtle (Lagerstroemia) seeds?
Crape Myrtle seeds do not require stratification but germinate best when exposed to warm temperatures and bright light. Sowing the seeds on the surface of the Seeds In A Cup® medium and pressing them gently ensures they receive the light necessary to trigger germination.
What is the optimal temperature for Crape Myrtle seed germination?
Crape Myrtle seeds sprout best at warm room temperatures between 21 and 26 degrees Celsius (70 to 79 degrees Fahrenheit), typically germinating in 14 to 21 days.
How deep should Crape Myrtle seeds be planted?
Press the seeds gently onto the surface of the provided Premium Nutrient-Rich Potting Soil. Do not cover them with soil, as they require light to germinate.
What USDA Hardiness Zones are suitable for Crape Myrtle trees outdoors?
Crape Myrtles are hardy in USDA Zones 7 through 9. In colder northern zones, they can be grown in containers and moved indoors for the winter.
Can I grow a Crape Myrtle tree indoors permanently?
While they can be started indoors and kept in containers on sunny patios, Crape Myrtles require full sun and outdoor seasonal changes to flower and thrive long-term.
Why does this kit use Premium Nutrient-Rich Potting Soil instead of coco coir discs?
Small seeds like Crape Myrtle can easily get lost or buried too deep in the coarse fibers of expanding coir discs. Our Premium Nutrient-Rich Potting Soil provides a stable, uniform surface for surface-sown seeds.
