Light Requirements
Crateva capparoides Andrews requires full sun exposure to thrive. Placing them in a spot that receives full sun for at least six hours a day will promote healthy growth.
Temperature Requirements
This plant species is native to tropical and subtropical regions, so it requires warm temperatures to grow. The ideal temperature range for Crateva capparoides Andrews is between 20-30°C (68-86°F). It can tolerate temperatures as low as 10°C (50°F) but may stop growing or die if exposed to frost.
Soil Requirements
Crateva capparoides Andrews thrives in well-draining soil with moderate fertility. The pH range should be slightly acidic to neutral, between 6.0-7.5. Adding compost or organic matter will improve soil quality and retain moisture. It is important to ensure that the soil is not waterlogged, as this can lead to root rot.
Cultivation Methods
Crateva capparoides Andrews commonly known as "spider tree" is a beautiful, deciduous, and drought-resistant flowering plant that originated from tropical regions of Africa, Asia, and Australia. It can grow to a height of 10-20 meters and a spread of about 4-6 meters.
The spider tree is a highly adaptable plant that can grow in different soil types such as sandy loam, clay loam, and well-drained fertile soil. It thrives in an environment with full sunlight exposure, with temperatures ranging from 20-30°C.
One can also propagate the spider tree from stem cuttings or seeds, whereby stem cuttings are the most recommended method. To propagate from stem cuttings, select a stem of about 15-20cm long with a two-node cutting. Place the cuttings in a container filled with sand or moist soil and keep them under shade to prevent dehydration. After three to four weeks, new growth will emerge.
Watering Needs
The spider tree requires moderate watering intervals. Water the plant regularly, especially when the soil is dry to the touch. Avoid overwatering, as it can lead to waterlogging and root rot.
During the dry season, water more frequently, especially on windy and hot days. However, during the rainy season, you can let the rain supply enough moisture for the plant. Proper drainage is essential to prevent waterlogging.
Fertilization
Spider trees require feeding with a balanced fertilizer regularly during the growing season. The best time to fertilize is during the months of June to September. Use organic fertilizers or inorganic fertilizers such as 10:10:10 N.P.K. in the proportion of 50-60 grams per plant.
Take care not to over-fertilize, as it can cause leaf burn or damage the plant. To avoid this, always follow the manufacturer's instructions for the correct application rate.
Pruning
Crateva capparoides Andrews requires regular pruning to maintain its desired shape and size and promote healthy growth. The best time to prune is after flowering, usually during the later months of September to November.
Use sterilized pruning shears to prevent the spread of diseases. Remove damaged, weak, and diseased branches that can affect the plant's growth. Prune the tips of the remaining branches and remove any dead flowers or fruits.
Regular pruning also promotes air circulation, sunlight penetration, and encourages the growth of new foliage and flowers.
Propagation of Crateva capparoides Andrews
Crateva capparoides Andrews, commonly known as the variegated or small-leaved crateva, is a deciduous tree native to Southeast Asia. This plant grows up to 10 meters tall and produces fragrant white flowers and edible fruits that resemble small cucumbers. Here are the propagation methods for this plant:
Seed propagation
Seed propagation is the most common method used to propagate Crateva capparoides. The seeds should be collected when ripe and sown immediately in a well-draining potting mix. The seeds should be sown at a depth of 1cm and kept moist at a temperature of 25-30°C. Germination should occur within 1-2 weeks, and the seedlings can be transplanted to individual pots once they have produced their second set of true leaves.
Cuttings propagation
Although seed propagation is the most common method, cutting propagation can also be successful for Crateva capparoides. Cuttings should be taken in the spring or summer from new growth. The cuttings should be approximately 10-15cm long and dipped in rooting hormone before being planted in potting mix. The cuttings should be kept moist, warm, and in a shaded area until rooting occurs in 4-6 weeks. Once rooted, they can be transplanted to individual pots.
Air layering propagation
Air layering is a propagation method where a portion of a stem is encouraged to root while still attached to the parent plant. This propagation method can be particularly useful for plants that are difficult to propagate from cuttings. For Crateva capparoides, air layering should be done during the growing season. Select a stem that is not woody, and remove a 2-5cm section of bark near a node. Apply rooting hormone to the exposed area and wrap it in moist sphagnum moss. Cover the moss with plastic wrap and secure it with rubber bands or tape. Roots should appear in 4-6 weeks, and the new plant can then be cut from its parent and planted in potting mix.
