Soil Requirements
The ideal soil for Tephrosia bracteolata var. bracteolata is well-draining, with a pH level of around 6.0-8.0. It can tolerate slightly acidic to slightly alkaline soil conditions. It prefers sandy or loamy soil with good fertility, but it can also grow in poor soils and on rocky terrain.
Cultivation of Tephrosia bracteolata Guill. & Perr. var. bracteolata
Tephrosia bracteolata is a hardy plant that can grow in various soil types. However, it thrives best in well-drained soils with a pH ranging between 6.5 and 7.5. The plant can be propagated through seeds or cuttings.
If you are starting from seeds, prepare a seedbed by loosening the soil and adding organic matter. Sow the seeds 1 cm deep and cover them with soil. Keep the soil moist to facilitate germination. Germination may take around two to three weeks.
If you are propagating through cuttings, choose healthy stem cuttings from a mature plant. Remove the leaves from the lower part of the stem, leaving two or three leaves on the upper part. Dip the cuttings in rooting hormone powder and plant them in a pot or the ground. Avoid direct sunlight until the cuttings have established roots.
Watering Needs
