Care
Watering
Keep the soil regularly moist during the active growing season, especially in hot and dry periods. Reduce watering in winter but never let the substrate dry out completely. Avoid waterlogging which promotes root rot.
Light exposure
Place your genipa in full sun or partial shade for optimal growth. In tropical or subtropical climates, some afternoon shade can be beneficial during periods of intense heat.
Soil and planting
Choose fertile substrate rich in organic matter and well-drained. Adding mature compost at planting time promotes rooting. Ensure good drainage to prevent root suffocation.
Fertilizing
Apply balanced fertilizer in spring and summer during the growth phase. You can use slow-release organic fertilizer or diluted liquid fertilizer every 2 to 4 weeks. Reduce fertilization in fall and winter.
Pruning and structure
Perform light shaping and balancing pruning after flowering to maintain nice branching. Remove dead or diseased branches as soon as they appear. No drastic pruning is necessary on a well-formed tree.
Health and pests
Watch for scales or whiteflies, particularly indoors or in greenhouses. Overly moist soil promotes fungal diseases; ensure good air circulation. Treat quickly with a gentle soapy water spray if needed.
Did you know?
The genipa is famous for its large fruit which produces a natural blue-black dye used traditionally by indigenous Amazonian peoples for body paintings and ritual patterns. This pigment, called genipin, was highly sought after during the colonial era. Today, the sweet and flavorful fruit remains appreciated throughout Latin America for making juices, jams, and desserts.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
