If it feels dry, water it until it drains out of the bottom. Reduce watering in winter when the plant is dormant.
Fertilization of Tephrosia hildebrandtii Vatke
Tephrosia hildebrandtii Vatke benefits from fertilizer applications to boost growth and flowering. Use a balanced NPK (Nitrogen, Potassium, and Phosphorous) fertilizer of 10-10-10 or 20-20-20 at a rate of 1 tablespoon per gallon of water. Apply the fertilizer every two weeks during the growing season, starting from spring and ending in fall. Avoid overfeeding the plant as it may develop excessive foliage at the expense of flowers.
Pruning of Tephrosia hildebrandtii Vatke
Prune Tephrosia hildebrandtii Vatke plant in early spring before new growth appears to remove dead, damaged, and diseased parts. Also, remove any crossing or crowded branches to promote airflow and light penetration. Trim the plant to shape it if necessary, but do not cut more than a third of the plant's total length. Deadhead the spent flowers to encourage more blooming. Regular pruning helps to maintain the plant's size and appearance, as well as preventing pest and disease problems.
Propagation of Tephrosia hildebrandtii Vatke
Tephrosia hildebrandtii Vatke can be propagated through two primary methods:
Seed Propagation
Seeds of Tephrosia hildebrandtii Vatke can be sown directly into the ground or in pots. It is recommended to soak the seeds in cold water for about 24 hours before sowing. The soil should be well-draining and rich in organic matter. The seedlings will usually appear after 2-3 weeks of sowing. It is important to keep the soil moist during germination.
Vegetative Propagation
Tephrosia hildebrandtii Vatke can also be propagated through stem cuttings. Select a healthy stem and cut it into 15-20 cm long pieces. Remove the leaves from the lower half of the stem and dip the cut end into rooting hormone powder to encourage root growth. Plant the treated stem in a pot filled with well-draining soil. Keep the soil moist and the pot in a warm and bright location. After a few weeks, the stem will develop roots and can be transplanted into a larger pot or into the ground.
Disease and Pest Management for Tephrosia hildebrandtii Vatke
