Step-by-Step Growing Guide
Guava (Psidium guajava) is one of the most productive and low-maintenance tropical fruit trees. It thrives in a wide range of well-draining soils with a pH of 4.5–7.0, tolerating poor soils better than most fruit trees. Amend at planting with compost and a balanced slow-release fertiliser. Space trees 5–8 metres apart, or train to multi-stem bushes 3 metres apart for intensive production. Water deeply twice weekly during dry periods; established trees are moderately drought-tolerant. Feed every 3 months with a balanced fertiliser (6-6-6-2 with micronutrients) during the growing season; increase potassium and reduce nitrogen once the tree begins regular fruiting. Prune after each harvest cycle to remove dead wood, maintain an open canopy, and stimulate new fruiting wood — guavas fruit on new growth. In subtropical or marginal tropical climates, protect from temperatures below 5°C with fleece or a sheltered wall position.
