Sowing guide
- Soak the hard seeds in room-temperature water before sowing.
- If a seed does not swell, lightly abrade one small area of the coat without reaching the embryo.
- Sow in a warm, free-draining mix and cover to about one seed thickness.
- Keep evenly moist with good ventilation; do not leave the pot standing in water.
Hard-coated legume seeds can emerge irregularly. Record which seeds were soaked or lightly scarified and allow enough time before disturbing the pot. Warmth and oxygen are as important as moisture.
Seedling care
Move established seedlings into stronger light gradually. Use deep pots and transplant before roots become crowded. Protect young growth from cold and reduce watering during cool, slow-growing periods.
This is a woody ornamental tree rather than a quick seasonal crop. Choose a sunny, well-drained position with room for its spreading or drooping branches. Seedlings can vary in form and flowering characteristics.
Seed note: Seeds are living material. Germination speed and percentage vary with seed age, storage, temperature, moisture and local conditions. Label the sowing date and treatment, keep the medium clean, and allow a reasonable period before judging the batch.
