Care
Watering
Water regularly during the growing season to keep the soil moist but well-drained. During heat waves, watering every 2 to 3 days may be necessary. Avoid letting water pool at the base, as this promotes root rot.
Exposure
Place your cleome in a sunny location (at least 6 hours of direct sunlight daily) for abundant blooms. It tolerates partial shade but produces fewer flowers. Protect it from strong winds that could damage its delicate stems.
Soil
Rich, well-drained soil enriched with organic matter promotes growth. Cleome adapts to neutral to slightly alkaline pH levels. Loosen the soil before planting and work in compost.
Fertilizer
Apply a balanced fertilizer every 15 to 20 days during the flowering period to support flower production. A fertilizer low in excess nitrogen will promote flowering more than foliage growth.
Pruning and maintenance
Pinch the tips of young plants to encourage a bushier, more branched habit. Remove spent flowers regularly to extend blooming. As an annual, the plant naturally completes its cycle at season's end.
Diseases and pests
Watch for whiteflies and spider mites in hot, dry conditions. Excess moisture can promote fungal diseases. Ensure good air circulation and avoid overhead watering.
Did you know?
Sticky cleome gets its name from the characteristic viscosity of its stems and leaves, covered with a fine glandular layer. Its unusual flowers with very long, prominent stamens resemble graceful spiders, earning it the popular nickname of 'spider flower.' Once used in traditional herbal medicine in South America, it has become a highly prized ornamental plant for modern gardeners seeking exotic charm.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
