How to keep Ximenia Caffra.
Light
The smooth-twigged sourplum thrives when it receives abundant sunlight each day, although it will also tolerate a spot with less light. Its native habitat is exposed to a high level of light, and this plant is adapted to those conditions. Too much or too little light can impede its healthy development and growth.
Water
The smooth-twigged sourplum thrives in semi-arid environments and is highly drought-tolerant. It requires watering only every 2 to 3 weeks. It also adapts to seasonal rainfall patterns, needing less water during dormancy and more as temperatures rise.
Temperature
Smooth-twigged sourplum comes from tropical areas, where the climate is generally warm and humid. Consequently, it is adapted to high temperatures and humidity. It does not tolerate sudden temperature changes and prefers a stable temperature environment, so it is important to avoid indoor temperature fluctuations. It usually cannot withstand cold and requires higher temperatures for growth. If the ambient temperature drops too low, the plant may stop growing or even die.
Fertilizer
Prefer organic fertilizers (e.g., fish emulsion, compost) instead of chemical ones for Smooth-twigged sourplum. Apply higher amounts of nitrogen and phosphorus to young plants in spring. Mix compost or fertilizer in before or after planting. For mature plants, supplement in spring with a balanced fertilizer or one targeted to specific deficiencies. Nutrient deficiency leads to small leaves, short branches, yellow/bronze foliage, acidic fruits, premature fruit drop, and splitting.
