Ixora arborea prefers well-draining soil that is rich in organic matter. The soil pH should be slightly acidic, between 5.5 and 6.5. A mixture of peat moss, perlite, and sand is an excellent choice for growing this plant. Make sure the soil is consistently moist but not waterlogged, as over-watering can cause root rot.

Cultivation

Ixora arborea Sm. is a tropical plant that prefers warm and humid climates. It grows best in well-draining soil with a pH range of 6.0 to 7.5. The plant thrives in full sun, but it can tolerate some shade. It can be propagated by seeds or cuttings.

Watering Needs

The plant requires regular watering to keep the soil moist, especially during the growing season. However, it is important not to overwater the plant as it can lead to root rot. Allow the soil to dry slightly before watering again. During the winter months, reduce watering but do not let the soil completely dry out.

Fertilization

Ixora arborea Sm. benefits from regular fertilization during the growing season, typically from spring to fall. Use a balanced fertilizer, such as a 10-10-10 or 20-20-20 blend, every four to six weeks. Be careful not to overfeed the plant as it can cause leaf burn and damage.

Pruning

The plant responds well to pruning and can be shaped into a desired form. Prune in the spring after blooming to promote new growth and encourage branching. Remove any diseased or damaged branches, as well as any that are crossing or rubbing against each other. Cut back up to one-third of the plant’s size to control its growth and appearance.

5. Water the cutting and place it in a shaded area.
6. Rooting usually takes 2 to 4 weeks.
7. Transplant the cutting to an individual pot when it has grown roots and at least two pairs of true leaves.

Propagation by Layering

Propagation by layering is a convenient method for those who don't want to damage the parent plant. This method also produces a mature plant in a short period. Here are the steps for propagating Ixora arborea Sm. via layering:

1. Choose a low-growing branch from the parent plant.
2. Remove the leaves and scratch the bark of the branch from where the stem touches the soil.
3. Apply rooting hormone to the scraped area.
4. Bury the scraped area in moist soil and keep it in place with stakes.
5. Water the soil regularly and keep it moist.
6. New root growth usually takes place in 6 to 8 weeks.
7. Cut the new plant from the parent plant and transplant it to an individual pot.

Propagation of Ixora arborea Sm. through seeds, cuttings, and layering can be achieved successfully with proper care and attention. Choose a method that suits your needs and start propagating your own Dwarf Ixora plant today.
