Propagation of Sesbania hirtistyla J.B.Gillett var. hirtistyla
Sesbania hirtistyla J.B.Gillett var. hirtistyla can be propagated by both seeds and cuttings.
Propagating through seeds
The ideal time to collect seeds is during the dry season when the pods start to mature and turn brown. These seeds should be collected and kept in a cool, dry place for storage.
To propagate through seeds, prepare a well-draining potting soil mix and sow the seeds around 2 to 3 cm deep in the soil. The seeds should be watered regularly and kept in a warm and sunny location. Germination typically takes around 7 to 14 days.
Propagating through cuttings
Another method for propagating Sesbania hirtistyla J.B.Gillett var. hirtistyla is through cuttings. Softwood cuttings are ideal for propagation and should be taken from healthy plants during the active growing season.
Before planting the cuttings, it is essential to remove all the lower leaves and ensure that the remaining leaves are adequately hydrated. Using a rooting hormone can also increase the success rate of propagation. The cuttings can be planted in potting soil mix and kept in a warm and bright location. With proper care and attention, they will develop roots in a few weeks.
Disease and Pest Management for Sesbania hirtistyla
