Soil Requirements
Ixora phellopus prefers well-draining soil that is rich in organic matter. The soil must be kept moist but not waterlogged, as too much water can cause root rot. A soil pH of 5.5 to 6.5 is optimal for the plant's growth. The addition of compost or humus can improve the soil quality and promote healthier growth.
Cultivation Methods
Ixora phellopus K.Schum., popularly known as Jungle Geranium, grows well in warm, tropical climates. It thrives in well-drained soil with pH levels between 5.5-7. Keeping the soil moist is essential for the plant’s growth. While it can tolerate partial shade, it flourishes in full sun for at least four hours every day.
You can grow the plant using seeds or stem cuttings. For stem cuttings, select healthy stems and cut at least 7cm long, remove the lower leaves, and plant in well-drained soil. Ensure that the soil is slightly moist at all times until the plant establishes a root system.
Watering Needs
Ixora phellopus K.Schum. requires a consistent amount of water to grow well. The soil should be moist, but not waterlogged. Overwatering can cause root rot and under-watering can result in stunted growth. Water the plant when the upper layer of soil feels dry to the touch, and avoid sprinkling water on its leaves.
Fertilization
Regular fertilization is essential for healthy growth and blooming of Ixora phellopus K.Schum. During the growing season, from spring to fall, apply a balanced, water-soluble fertilizer every two weeks. During winter and when the plant is not actively growing, reduce the fertilization to once a month.
Pruning
Pruning Ixora phellopus K.Schum. is necessary to promote bushier growth and maintain its shape. You can prune in the spring before new growth or after blooming. Cut back the stems by a third to half their size, and remove any dead or diseased branches. Also, trim the plant’s lower branches to keep it looking tidy and prevent pests and diseases.
Propagation of Ixora phellopus K.Schum.
Ixora phellopus K.Schum. can be propagated through various methods, including stem cuttings, air layering, and seeds.
Stem Cuttings
Stem cuttings are the most common method of propagation for Ixora phellopus K.Schum. This method involves taking a 6-8 inch cutting from a healthy plant and removing all but a few leaves at the top. The bottom of the cutting is then dipped in rooting hormone and planted in a well-draining potting mix. The cutting should be watered regularly and kept in a warm, humid environment until roots form, which can take several weeks.
Air Layering
Air layering is another method of propagation for Ixora phellopus K.Schum. This method involves making an incision in the stem of a healthy plant and wrapping it in damp sphagnum moss or peat moss. The moss is then covered with plastic wrap and tied with string to keep the moisture in. Once roots have formed, the stem can be cut below the root ball and potted in a well-draining potting mix.
Seeds
Propagation from seeds is possible, but it is not common. Seeds should be planted in a well-draining potting mix and kept moist in a warm, humid environment. Germination can take several weeks to several months, and the resulting plants may not be true to the parent plant.
Disease Management for Ixora Phellopus K.Schum.
Preventing diseases should be the primary focus of gardeners, as it is easier to prevent it than to cure it. Adequate soil preparation, balanced fertilization, and proper irrigation practices will help in preventing diseases. Additionally, using disease-free seeds, sterilized soil, and clean gardening tools will prevent the transfer of diseases in the first place.
Some of the common diseases that affect Ixora phellopus are fungal infections including leaf spot, stem rot, and powdery mildew. Incorporating a fungicide spray or treatment can help reduce the damage caused by fungi.
