Guide to Growing Carissa Carandas
Carissa Carandas Benefits
Carissa carandas, a resilient and multi-purpose shrub, offers numerous benefits to gardeners and consumers alike. The evergreen leaves and fragrant star-shaped blooms make this a desirable plant for outdoor spaces. The fruits, known for their high antioxidant content and unique taste, are often used in culinary creations such as pickles, chutneys, jams, and jellies.
Moreover, the plant has been utilised in traditional medicine, particularly in Ayurveda, to treat various ailments, including digestive disorders, fever, inflammation, and skin conditions. Because of its durability, resilience to pests, and ability to thrive in a variety of settings, Carissa carandas is an excellent option for gardeners of all skill levels.
Choosing and Preparing the Site
- Selecting the right location: Select a spot that gets at least 6-8 hours of sunlight every day, since Carissa carandas does best in full sun to moderate shade. The plant is adaptable so long as it’s planted in well-drained soil. Additions of organic matter can assist heavy clay soils in draining better.
- Soil preparation: To improve soil quality, mix in aged compost or well-rotted manure to provide nutrients and improve soil structure. Ensure the soil has a pH between 6.0 and 7.5, as Carissa carandas prefers slightly acidic to neutral soil.
- Space allocation: Plants need to have enough room to grow and thrive, so leave at least 8 feet between each one.
Planting and Propagation
Propagation methods: Seeds, cuttings, and even layering may all be used to spread the Carissa caranda. Plant seeds in a seed compost-filled tray or pot, then cover them with a light coating of compost or vermiculite. Keeping the soil wet and the temperature around 75 degrees is important.
Usually, seeds need three to four weeks to germinate. Semi-hardwood stem portions are best for cutting cuttings in the early summer, whereas hardwood cuttings are best in winter. To layer, bend a branch that is already somewhat low to the ground and secure it with a peg or weight until roots emerge.
Transplanting: Transplant the seedlings into separate pots after they have established a couple of sets of genuine leaves. Allow them to grow in a sheltered spot until they reach about 12 inches in height, and then plant them in their final positions in the garden.

Caring for Carissa Carandas
- Watering: Carissa carandas is drought-tolerant but requires regular watering during the first year to establish a strong root system. Provide deep watering every 7-10 days during dry periods, and reduce the frequency as the plant matures.
- Fertilizing: Apply a balanced, slow-release fertilizer in spring and again in mid-summer to support growth and fruit production. Take care not to over-fertilize since doing so might promote leaf growth at the cost of fruit development.
- Mulching: Mulch the soil around the plant’s roots with organic material like straw, wood chips, or shredded leaves to keep the soil wet, prevent weed growth, and maintain a consistent temperature.
- Pest and disease control: Carissa carandas is not very susceptible to infestations of insects, but you should still keep an eye out for mealybugs and aphids on occasion. Neem oil or insecticidal soap are two effective ways to eliminate these unwanted guests. In order to ward against fungal diseases, ensure that adequate air circulation and cleanliness are maintained.
Pruning and Training
- Pruning: Prune Carissa carandas during the dormant season to maintain an open canopy and encourage fruit production. Remove dead, damaged, or crossing branches, and thin out crowded areas to improve air circulation. Prune to maintain the desired shape and size, but avoid excessive pruning, as it can reduce fruit production.
- Training: Carissa carandas can be trained in various forms, such as hedges, small trees, or espaliers. Select a strong central leader for a tree form and remove competing branches. Trim the top and sides regularly for a hedge to maintain the desired height and width. Attach horizontal branches to a trellis or wall for espalier and regularly prune to encourage a flat, two-dimensional growth pattern.
Harvesting and Storage
- Harvesting: Carissa carandas fruits typically ripen between July and September. When ripe, the fruits change from green to deep red or black. Harvest the fruits by gently twisting and pulling them from the plant, taking care not to damage the fruit or branches.
- Storage: Freshly harvested fruits can be stored at room temperature for up to a week. Refrigerate the fruits in a plastic bag or airtight container for longer storage. You can also dry, freeze, or make the fruits into preserves or chutneys to preserve the fruits.
Landscaping and Ornamental Uses
- Landscaping: Carissa carandas is an attractive and versatile plant that can be used as a focal point, border, or ground cover in tropical and subtropical landscapes. Its dense, evergreen foliage provides year-round interest, while its fragrant, star-shaped flowers and colourful fruits add seasonal beauty.
- Ornamental uses: The plant’s thorny branches can create a living fence or barrier. In addition, its tolerance for various environmental conditions makes it suitable for coastal and urban gardens, erosion control and wildlife habitats.
