During the vegetative period, provide some fertilizer for green plants, every 15-20 days, mixed with the water of the watering.
For the planting of this type of plant, use balanced, rich and soft universal soil, possibly mixed with pumice stone or perlite, to increase drainage; another useful element for drainage is the sand, which can be mixed with peat and mould to obtain a compound with good properties.

Corinocarp – Corynocarpus laevigata: Parasites and diseases
Poor ventilation and low humidity conditions can favour the attack of cochineal and mites. Excessive humidity, on the other hand, can lead to the onset of radical rottenness that can cause the death of the plant itself; for this reason, it is advisable to carefully check that the soil is sufficiently drained to avoid the formation of waterlogging.
