Harrisonia requires a balance of sunlight and shade, thriving in bright, indirect light. Consistent moisture is essential, yet the soil must drain well to prevent root rot. Preferably, the temperature should be warm without drastic fluctuations, and a well-aerated, fertile soil promotes healthy growth. Gardeners often face challenges like pest invasions, particularly from aphids and spider mites, as well as potential fungal diseases. Seasonally, harrisonia may need protection from intense summer sun and winter cold, with adjustments in watering and positioning to maintain a stable growing environment.
