Cultivation methods
The plant Agathosma variabilis Sond., also known as the Sutherlandia, is a perennial shrub that grows in dry, arid regions. It is indigenous to South Africa and is typically grown as an ornamental plant. To cultivate this plant, you will need well-draining soil and a sunny, sheltered spot in your garden. Avoid areas with excessive moisture or poor drainage as they can lead to root rot, which is harmful to the plant.
Before planting, prepare the soil by mixing compost and sand to improve drainage. Plant the Sutherlandia in the spring or early summer, ensuring that the hole is deep enough to accommodate the root ball of the plant. Add a layer of mulch around the base to help retain moisture and keep the roots cool.
Watering needs
The Sutherlandia is a drought-resistant plant that can survive on minimal watering. It thrives in arid regions and can withstand prolonged periods of dryness. However, ensure that your plant gets sufficient water during the first few weeks of planting to help establish the roots. Afterward, water the plant only when the soil is dry to the touch. Avoid overwatering the plant, as this can lead to root rot.
Fertilization
Agathosma variabilis Sond. does not require a lot of fertilizer to grow. In fact, too much fertilizer can lead to leggy growth and fewer blooms. It is recommended to fertilize the plant once a year in the spring with a balanced, slow-release fertilizer. Alternatively, you can use organic fertilizers such as compost or well-rotted manure to supplement the nutrients in the soil.
Pruning
Pruning is essential to keep the Sutherlandia plant healthy and to encourage bushier growth. Prune the plant in late winter or early spring before the growing season starts. Remove any dead or damaged branches, and cut back overgrown stems to promote new growth. You can also prune the plant after it has finished blooming to remove spent flowers and encourage new blooms.
