Hewittia malabarica (L.) Suresh thrives in bright, indirect sunlight. It is essential to place the plant near a window that receives a lot of natural light. However, it must not be exposed to direct sunlight as it can damage the leaves and stunt growth. If the plant does not receive enough light, it may become leggy and lose its vibrant green color. Supplemental fluorescent or LED grow lights can be used if natural light is limited.
Temperature Requirements
Hewittia malabarica (L.) Suresh grows well in warm temperatures ranging from 20-30°C (68-86°F). The plant is native to tropical regions, so it is well-adapted to high humidity levels. It is essential to maintain a consistent temperature throughout the day and try to avoid extreme temperature fluctuations. If the plant is placed in an area with too much heat or cold, it may become stressed and eventually die.
Soil Requirements
Hewittia malabarica (L.) Suresh requires well-draining soil that retains some moisture. A mixture of peat moss, vermiculite, and perlite is ideal for the plant. The pH level of the soil should be slightly acidic, around 6.0-6.5. The plant is sensitive to overwatering, so it is important to let the soil dry out slightly before watering again. It is also recommended to fertilize the plant every few weeks during the growing season with a balanced liquid fertilizer.
Cultivation Methods
Hewittia malabarica (L.) Suresh is a perennial plant that requires well-drained soil and partial shade to full sun exposure for optimal growth. The plant can be propagated by seeds or cuttings, and the optimal time for planting is during spring or rainy seasons. For optimal growth, the plant should be grown in a slightly acidic soil with a pH range of 5.5 to 6.5.
Watering Needs
The Hewittia malabarica (L.) Suresh plant requires adequate water supply to maintain its foliage and flower production. The plant should be watered deeply twice a week during the growing season and once a week during the dormant season. However, overwatering should be avoided, as it can lead to root rot and other plant diseases.
Fertilization
Fertilization is essential for the optimal growth and development of Hewittia malabarica (L.) Suresh. The plant should be fertilized twice a year, during the growing season, with a balanced fertilizer with an NPK ratio of 10-10-10. Fertilization should be done at least two weeks after planting and two weeks before the first frost.
Pruning
Pruning helps to maintain the shape and size of Hewittia malabarica (L.) Suresh plant. Pruning should be done in early spring before the start of the growing season. During pruning, dead or damaged stems, leaves, and flowers should be removed. Also, remove any suckers or water sprouts growing from the root or the base of the stem. Pruning helps to encourage new growth and ensure optimal flowering.
Propagation of Hewittia malabarica
Hewittia malabarica is a perennial herb that can be propagated through different methods that include seed propagation, stem cutting, and division.
Seed propagation
The propagation of Hewittia malabarica through seeds is possible, but it requires specific conditions to ensure success. The seeds must be collected from the ripe fruit and promptly planted in a well-prepared bed. The soil must be moist, and the bed must be protected from direct sun exposure. The seeds take time to germinate, and they may take up to six months to sprout. Once they have germinated, the seedlings should be transplanted to their containers or directly to their desired planting site.
Stem cutting propagation
Hewittia malabarica can also be propagated through stem cuttings. The stem cuttings should be taken from mature plants with healthy stems and leaves. The cuttings must be dipped in a rooting hormone, then planted in a well-draining propagation mix. The pots should be placed in a shaded area and kept humid. In about four to six weeks, the cuttings should have rooted, and they can be transplanted to their permanent location.
Division propagation
Division propagation is another method of propagating Hewittia malabarica. It involves dividing the mature plant's root system into smaller segments, each with crowns and roots. The divided plant segments should be planted in a well-draining soil mix, pre-moistened, and kept humid in a shaded spot. Over time, they establish themselves and then can be transplanted to their permanent site.
Disease and Pest Management for Hewittia malabarica (L.) Suresh
Hewittia malabarica (L.) Suresh, commonly known as Malabar dewdrop or Chirakadambu, is a tropical tree native to India, with attractive white flowers and shiny green leaves. While this plant is generally disease-resistant and hardy, it is not entirely immune to diseases and pests. Here are some common diseases and pests that might affect the plant, along with suggestions on how to manage them.
Diseases
Leaf spot disease: Leaf spots are a common symptom of fungal or bacterial infection in plants, and Hewittia malabarica is no exception. The spots will be yellow or brown with a dark outline. If left unmanaged, the affected leaves will turn yellow, then brown, and finally fall off. To manage leaf spot disease, remove the affected leaves as soon as you notice them and dispose of them away from the plant. Avoid wetting the leaves while watering the plant and ensure proper drainage to discourage the growth of fungi.
Anthracnose: Hewittia malabarica is susceptible to anthracnose, a fungal disease that causes brown or black spots on leaves and stems. The disease typically appears after a spell of high humidity or damp weather. To manage anthracnose, prune affected branches and stems as soon as possible. Avoid watering the plant from above to reduce the humidity level around the plant. Applying copper-based fungicides can also be helpful.
Pests
Aphids: Aphids are small, soft-bodied insects that suck sap from plants, stunting their growth and causing leaves to curl and yellow. To control aphids, spray the plant with a strong jet of water to dislodge them or apply insecticidal soap according to label instructions. You can also encourage the presence of natural predators like ladybugs and lacewings to keep aphids in check.
Mealybugs: Mealybugs look like tiny balls of cotton and typically congregate on the undersides of leaves and along the stems. They can cause stunted growth, yellowing, and leaf drop in Hewittia malabarica. To manage mealybugs, dab the affected areas with a cotton swab dipped in rubbing alcohol or apply insecticidal soap according to label instructions. Repeat the treatment every 7-10 days until the problem is resolved.
Hewittia malabarica is a beautiful tropical tree that adds a touch of exoticism to any garden. With the right care and attention, you can keep it healthy and free from diseases and pests.
