Care
Watering
Water regularly during the growing and flowering periods, keeping the soil moist but well-drained. Reduce watering in autumn and winter, especially in regions where the plant loses its foliage. Avoid standing water which promotes root rot.
Exposure and light
Place this shrub in a sunny location for abundant flowering. It tolerates partial shade but will flower less generously. Protect it from strong and violent winds that could damage its structure.
Pruning and structure
Perform light formative pruning in spring to maintain a balanced shape and encourage branching. Remove dead or damaged branches. Moderate pruning after flowering helps rejuvenate the shrub and stimulate the next flowering.
Soil preparation and type
Choose soil rich in organic matter, well-drained and slightly acidic to neutral. Incorporate compost or potting soil at planting. A mulch at the base helps maintain moisture and moderate temperature fluctuations.
Fertilization
Apply balanced fertilizer in spring to support growth. During flowering, a monthly application of potassium-rich fertilizer extends and intensifies flower production. Reduce fertilization in autumn and winter.
Pests and diseases
Watch for spider mites and whiteflies, especially in hot, dry climates. Excess humidity can promote leaf fungi: ensure good air circulation and avoid wetting the foliage. Good hygiene and regular inspection prevent most problems.
Did you know?
Malvaviscus arboreus is called "Apple of Mexico" in English, referring to its fruits that resemble small pink-red apples. Its tubular flowers and fleshy fruits make it a highly prized ornamental plant in tropical and subtropical gardens, where it also attracts hummingbirds and pollinating butterflies.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
