Temperature Requirements
Agathosma recurvifolia Sond. is well adapted to hot and dry conditions and can tolerate a wide range of temperatures. It can grow in warm temperatures ranging between 20°C and 30°C, but it can also tolerate occasional fluctuations below 0°C. Although the plant is adapted to hot and dry conditions, it can still grow well in humid areas, provided temperature conditions are met.
Soil Requirements
The plant prefers a well-draining soil that is slightly sandy with a pH range between 6.5 and 7.5. It can tolerate soils with low fertility, but it grows best in soils enriched with organic matter. It prefers soils that have a slightly acidic to neutral pH, and soils that are too alkaline or too acidic can adversely affect the plant's growth. Agathosma recurvifolia Sond. is adapted to grow in rocky and sandy soils, and it can also grow well in pots with well-draining potting soil mixes.
Cultivation Methods
Agathosma recurvifolia Sond. plant is a native of South Africa and is adapted to hot and arid conditions. The plant grows well in well-draining sandy soils with a pH between 5 and 7. It needs good sunlight exposure and can tolerate extreme heat and cold conditions. The ideal zone for its cultivation is USDA hardiness zone 9-11, and it can be grown both indoors and outdoors as long as it gets enough exposure to direct sunlight.
Watering Needs
The Agathosma recurvifolia Sond. plant needs moderate watering during the summer season and less water during the winter season. Watering should be done only when the top one inch of soil is dry. Overwatering can cause root rot and other related problems. So, it is essential to maintain a well-draining soil medium to avoid waterlogging. Also, excessive watering can lead to stress on the plant.
Fertilization
The Agathosma recurvifolia Sond. plant can benefit from a slow-release fertilizer applied during the growing season. Apply the fertilizer once every six months or follow the instructions on the package. Nitrogen-based fertilizers, such as 20-20-20, are good for the growth of the plant. Avoid excessive fertilizer application, as it can lead to salt buildup and damage the roots.
Pruning
The Agathosma recurvifolia Sond. plant requires pruning once every year to maintain its shape and size. Pruning should be done after the blooming period. Using a sharp pair of scissors, remove dead or diseased branches as well as any branches that are out of shape. It is also advisable to remove older branches to allow new growth. Pinching the tips of the branches can also help to promote bushier growth.

The soil should be kept moist but not too wet until germination which may take up to 4 weeks. The seedlings should be transplanted into individual pots once they have developed a few true leaves. Young plants should be kept in a bright location away from direct sunlight and should be watered sparingly.
Cuttings Propagation
Agathosma recurvifolia Sond. can be propagated through softwood cuttings taken in spring or semi-ripe cuttings in summer. Cuttings should be taken from healthy plants and dipped in rooting hormone before being planted in well-draining soil mix. The cuttings should be kept in a bright and warm location away from direct sunlight and should be watered sparingly. Roots should develop in 3-4 weeks, at which point the young plants can be transplanted into individual pots.
Division of plants
Agathosma recurvifolia Sond. can also be divided during early spring or late summer. The root-ball should be carefully lifted from the ground and divided into smaller sections with a sharp, clean knife. Each division should have some healthy roots and shoots. The divisions should be planted in well-draining soil mix and watered sparingly until new growth appears.
Disease and Pest Management for Agathosma recurvifolia Sond.
Agathosma recurvifolia Sond. is a plant species belonging to the family Rutaceae and is native to Southern and Eastern Africa.

Here are some common diseases and pests that affect the plant and ways to manage them:
Diseases
Cercospora Leaf Spot: This is a fungal disease that leads to the development of dark brown spots on the leaves of the plant. Infected leaves may fall off early, leading to defoliation of the plant. The disease can be controlled by removing infected leaves and applying fungicides that contain copper.
Phytophthora Root Rot: This is a soil-borne disease that affects the roots of the plant. Symptoms include yellowing and wilting of the leaves. The disease can be managed by avoiding waterlogged soil, improving drainage, and using fungicides that contain metalaxyl.
Verticillium Wilt: This is a soil-borne disease that affects the vascular system of the plant, leading to wilting and death. There is no cure for the disease, and infected plants should be removed and destroyed to prevent the spread of the disease.
Pests
Spider Mites: These are tiny pests that suck sap from the leaves of the plant, leading to yellowing and drying of the leaves. The pests can be managed by using insecticidal soap or neem oil. It is also important to maintain high humidity levels to prevent the pests from thriving.
Scale Insects: These are small pests that attach themselves to the leaves and stems of the plant, sucking sap and causing yellowing and distortion of the leaves. They can be managed by removing infected leaves and stems or using insecticidal soap or neem oil.
Caterpillars: These are the larvae of moths and butterflies that feed on the leaves of the plant, leading to defoliation. They can be managed by picking them off by hand or using biological controls such as Bacillus thuringiensis (Bt).
By being proactive and monitoring for these pests and diseases, Agathosma recurvifolia Sond. can thrive and provide its medicinal benefits.
