Care Guide
How to Water
Water every 7 days, keeping soil moist but well-drained. Once established, the plant tolerates brief dry spells. Avoid waterlogging as it can cause root rot.
Lighting
Grow in full sun (minimum 6 hours of direct light daily). The more sun it receives, the more it blooms. Tolerates light shade but with significantly reduced flowering.
Ideal Soil
Prefers sandy or calcareous soils with pH between 6.0 and 8.0 and good drainage. Add organic matter to enrich the substrate. Avoid heavy clay soils that retain water.
Recommended Pot
Ceramic or terracotta pots with drainage holes. For climbing, use larger containers (12+ inches) with trellis or support. In gardens, plant directly in the ground near fences or support structures.

How to Propagate
Stem Cutting
Use clean, sharp tools to prevent disease. Change water every 3-4 days if propagating in water. Rooting is faster in warm climates.
- 1 Cut a healthy stem of 4-6 inches just below a node
- 2 Remove lower leaves, keeping 2-3 leaves at the top
- 3 Apply rooting hormone powder to the cut end
- 4 Plant in moist sandy substrate or place in water until rooted
- 5 Keep in indirect light until roots develop
Materials needed:
Seed Sowing
Scarification improves germination rates. Keep substrate moist but not waterlogged during germination.
- 1 Lightly scarify seeds with fine sandpaper
- 2 Soak seeds in warm water for 12-24 hours
- 3 Sow in moist, well-drained substrate 0.2 inches deep
- 4 Keep in a warm location (77-86°F) with indirect light
- 5 Transplant when seedlings reach 4 inches tall

Common Problems
Spider Mites
Spider mites are tiny arachnids (less than 1/20 inch long) related to spiders and ticks that feed on plant sap. They thrive in hot, dry conditions and can cause significant damage to ornamental and vegetable plants. During severe infestations, crop losses can reach 14% or higher as these pests disrupt vital plant processes including photosynthesis, carbon dioxide absorption, and transpiration.
Whiteflies
Whiteflies are small, soft-bodied, winged insects closely related to aphids and mealybugs. They are moth-like in appearance, about 1/16 inch long, triangular in shape, and gray-white in color. These sap-sucking pests feed on plant tissue, causing yellowing, stunted growth, and wilting. They also excrete honeydew, which attracts ants and promotes sooty mold growth. Whiteflies can transmit serious plant viruses.
Root Rot
Root rot is a serious fungal disease that affects the root system of plants, causing them to decay and die. It is primarily caused by overwatering, poor drainage, or soil-borne fungi such as Pythium, Phytophthora, Rhizoctonia, and Fusarium. The disease thrives in waterlogged conditions where roots are deprived of oxygen, making them susceptible to fungal infection.
Powdery Mildew
Powdery mildew is a common fungal disease caused by various fungi species including Erysiphe, Podosphaera, Oïdium, and Leveillula. It affects over 10,000 plant species worldwide. The disease thrives in warm, dry climates with high humidity and appears as a distinctive white powdery coating on plant surfaces.
