Rogeonella chevalieri is a perennial plant that requires specific cultivation methods for optimal growth and health. It thrives in well-draining soils, preferably sandy or loamy, with a neutral pH range of 6.0-7.5. The plant prefers full sun exposure but can tolerate some shade during hot afternoons.
Propagation of Rogeonella chevalieri can be done using seeds or stem cuttings. Sow the seeds in trays in early spring, indoors or in a greenhouse, and transplant the seedlings outdoors when they reach a manageable size. Root the stem cuttings in water or a well-draining rooting medium before transplantation.
Watering Needs
Rogeonella chevalieri requires moderate watering, with the soil kept slightly moist but not waterlogged. Water thoroughly once a week, adjusting the frequency depending on the soil moisture and weather conditions. In the hot summer months, increase watering to maintain adequate soil moisture levels to prevent wilting and damage.
Fertilization
Fertilize Rogeonella chevalieri twice a year, in spring and fall, using a balanced fertilizer with equal proportions of nitrogen, phosphorus, and potassium. Apply the fertilizer at the base of the plant and water well to ensure absorption. Avoid overfertilization as it can cause damage and reduce overall plant health.
Pruning
Prune Rogeonella chevalieri in late winter or early spring before new growth starts. Remove any dead, damaged, or diseased parts, cutting them back to healthy tissue.
