It thrives in well-draining soil that has been enriched with organic matter, such as compost or well-rotted manure. This plant prefers a location that gets partial to full shade, with protection from harsh winds. Ensure that the site is not waterlogged to avoid root rot.
Watering needs
The watering needs of Ilysanthes pulchella Skan subsp. rhodesiana Norl. depend on the prevailing environmental conditions. The plant requires moist but not waterlogged soil. During the growing season, water the plant deeply once a week, or when the top 2-3 inches of soil feel dry. In the dormant season, reduce watering to every two weeks to avoid overwatering.
Fertilization
Ilysanthes pulchella Skan subsp. rhodesiana Norl. requires regular fertilization to promote healthy growth and blooms. Apply a balanced fertilizer, such as 10-10-10, every three months during the growing season, following the instructions on the package.
Pruning
Pruning Ilysanthes pulchella Skan subsp. rhodesiana Norl. is essential to promote bushy growth and maintain the plant's shape. The best time to prune is after flowering when the plant is still actively growing. Using clean, sharp pruning shears, remove any dead, diseased or damaged stems, cutting back to healthy tissue. Pinch back the tips of the remaining stems to promote branching and denser foliage.
Propagation of Ilysanthes pulchella Skan subsp. rhodesiana Norl.
Propagation of Ilysanthes pulchella Skan subsp. rhodesiana Norl. can be done through various methods which include:
Seed propagation
Seeds of Ilysanthes pulchella Skan subsp. rhodesiana Norl. can be sown in a well-draining soil mix and kept moist until germination, which usually occurs within 1-2 weeks. The seedlings can then be transplanted 6-8 weeks after germination.
Division
The plant can also be propagated through division. This is done by carefully dividing the root ball into sections and replanting each section into a new pot or location. It is important to ensure that each section has enough roots and foliage to support its growth.
Cuttings
Another propagation method is through stem cuttings. Cut a healthy stem just below a node and remove the lower leaves. Place the cutting in a well-draining soil mix and keep it moist until it has developed roots, usually within 2-4 weeks. The cutting can then be transplanted into a new pot or location.
It is important to note that Ilysanthes pulchella Skan subsp. rhodesiana Norl. prefers warm temperatures and light shade. Healthy plants will usually produce new growth each year and can be propagated through the above methods to create new plants.
