- 4 Keep in a warm location (25-30°C) with indirect light
- 5 Expect irregular germination over 4-8 weeks
Materials needed:
Stem Cutting
Keep substrate slightly moist but never waterlogged. Rooting can be slow — be patient.
- 1 Take semi-hardwood cuttings of 10-15 cm from current year growth
- 2 Remove lower leaves, keeping 2-3 at the tip
- 3 Dip base in rooting hormone powder
- 4 Plant in sandy, well-drained substrate

What Diseases Commonly Affect Caper Bush?
TLDR: Caper Bush is susceptible to 6 known diseases. Monitor regularly for early detection.
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.
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.
Aphids
Aphids are small, soft-bodied, pear-shaped insects (1/16 to 1/8 inch long) that feed by sucking nutrient-rich sap from plants. They reproduce rapidly and can quickly weaken plants, causing distorted growth and transmitting plant viruses. Aphids come in various colors including green, black, red, yellow, brown, and gray. They secrete honeydew, a sticky substance that attracts ants and encourages sooty mold growth.
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.
Meaning & Symbolism
Symbol of resilience and tenacity in harsh conditions. In Mediterranean culture, it represents the persistence of life in the most inhospitable environments.
