🌱 How to Care for Kola nut to Prevent Anthracnose?

💧 How to Water

Keep the soil consistently moist but avoid a waterlogged, suffocating root zone: water when the top 2-3 centimeters of soil have dried out. Mature specimens can tolerate short periods of drought, but young plants require regular, balanced watering.

☀️ Lighting

It prefers bright, filtered (indirect) light; direct sunlight can scorch its leaves. In its natural habitat, it grows in the lower canopy of the rainforest, but it develops a denser crown and produces more fruit in open, sunnier locations.

🪴 Ideal Soil

It requires deep, humus-rich, well-aerated soil: a mixture of peat, perlite, and mature compost is ideal. It poorly tolerates high pH, calcareous soils; a slightly acidic range between 5.5 and 6.5 is most suitable.
