Soil Requirements
Indigofera kelleri Baker f. can grow in various types of soils ranging from sandy to loamy. However, it thrives best in well-draining soil with a pH value ranging between 6.5 to 7.5. The soil should be rich in nutrients and organic matter, and it should retain moisture without being waterlogged.
Cultivation Methods
Indigofera kelleri Baker f. is a perennial plant native to Africa. It thrives well in warm conditions and is a drought-tolerant plant. It can be grown in a variety of soil types, ranging from sandy or loamy to clay soils. The plant enjoys full sun and grows well in areas that receive between 500mm to 1200mm of rainfall per year.
The plant can be propagated through seeds or cuttings. The seeds should be soaked in warm water for 24 hours before being sown in a well-drained mixture. Cuttings should be taken during the growing season and planted in warm soil.
Watering Needs
Indigofera kelleri Baker f. is a drought-tolerant plant but requires regular watering during the growing season. Water should be applied to the soil and not on the leaves. The plant prefers moist soil but can withstand drought conditions for short periods.
Fertilization
Indigofera kelleri Baker f. does not require frequent fertilization as it can fix nitrogen naturally from the air. However, if the plant is grown in poor soil, it can benefit from an application of a balanced fertilizer. Ensure to use organic fertilizer as it enhances soil structure and fertility.
Pruning
Pruning of Indigofera kelleri Baker f. is not necessary, but it can help to maintain its shape and size. The plant can be pruned during the dormant season to remove dead or damaged branches. Pinching back the tips of the plant can also encourage new growth and bushier growth.
Propagation of Indigofera kelleri Baker f.
Indigofera kelleri Baker f. is propagated mainly through seeds and stem cuttings.
Propagation through seeds
The seeds of Indigofera kelleri Baker f. can be collected from mature pods that have turned brown. The seeds can be soaked overnight before sowing them. Seeds can be propagated in soil or seed-starting mix. They will germinate in 7 to 21 days if kept in a warm and moist environment.
Propagation through stem cuttings
The stem cuttings of Indigofera kelleri Baker f. are taken during the early summer from mature plants. Cuttings that have 2 to 3 nodes are used for propagation. The leaves from the lower half of the stem should be removed. The cuttings can be dipped in rooting hormone before planting them in soil or rooting mix. The cuttings should be kept in a humid environment, and they will root in 2 to 3 weeks. Transplant the rooted cuttings to the desired location once they have sufficient root development.
