💧 Care & Maintenance Guide

Light:
Performs best in full sun. Some hybrids tolerate partial shade, and afternoon protection can help in intensely hot locations. Insufficient light may reduce flowering.

Watering:
Allow the soil to dry between thorough waterings. Avoid standing water and prolonged saturation. Some large-leaved hybrids need more frequent watering than smaller forms.

Soil:
Prefers a fast-draining planting mix. A cactus or succulent mix works well in containers with drainage holes.

Temperature:
Thrives in warm weather. Protect from frost, freezing temperatures, and cold, wet conditions.

Fertilization:
Feed lightly during spring and summer with a balanced fertilizer, following label directions. Excess fertilizer can encourage leafy growth at the expense of flowers.

Pruning:
Prune selectively to maintain shape and remove weak or damaged branches. Wear protective gloves and eye protection, avoiding contact with the milky sap.

Spacing:
Allow approximately 2–3 ft between plants, adjusting for the cultivar’s mature spread. Keep thorny branches clear of pedestrian areas.

🌺 Flowering Tip

The colorful display comes mainly from long-lasting bracts surrounding tiny flowers. Provide adequate sunlight and avoid excessive feeding to support consistent flowering.

Common Issues

Overwatering can cause root and stem rot. Plants may shed leaves during stress or seasonal rest. Monitor for mealybugs, scale, and spider mites.
