Seasonal Care Spring: Fertilize and divide if needed. Summer: Water regularly, deadhead spent flowers. Fall: Cut back stems after flowering. Winter: Mulch to protect roots in colder climates.

Pride of India

Repotting Not applicable for outdoor trees. Indoor attempts would require annual repotting into larger containers until size becomes unmanageable.
Pruning Prune in late winter or early spring to remove dead or crossing branches and shape the tree. Avoid 'crape murder' (severe topping), which can damage the tree and promote weak growth.
Fertilizing Balanced fertilizer (10-10-10) in spring and early summer, diluted to half strength. Avoid fertilizing in late summer to allow the plant to harden off for winter.
Seasonal Care In winter, provide protection from frost in colder climates. Prune in late winter or early spring to remove dead or crossing branches. In summer, ensure adequate watering during hot, dry periods.

Pride of India

What are the light requirements for Pride of India?

Pride of India requires bright, indirect light to thrive indoors. Insufficient light can lead to leggy growth, reduced flowering, and pale foliage. Place your plant near an east- or west-facing window where it can receive ample light without direct sun exposure. If you have a south-facing window, use sheer curtains to filter the sunlight. Rotate the plant regularly to ensure all sides receive adequate light. If natural light is limited, consider using a grow light to supplement its needs. A fluorescent or LED grow light positioned 12-18 inches above the plant can provide the necessary light for healthy growth and flowering.
