Complete Growing & Harvesting Guide

Follow our detailed scientific agricultural cultivation guide to keep your Guava thriving and high-yielding.

Water deeply once a week. Guavas are drought-tolerant but require consistent watering during flowering and fruit development.

Prune annually in late winter. Focus on thinning the inner branches to improve light penetration and keeping the tree compact.

Feed every 2-3 months with balanced organic fruit fertilizer rich in nitrogen, phosphorus, and potassium.

Requires full sun, demanding 6 to 8 hours of direct light daily. Shaded branches result in leggy canopy and low fruit yields.

Extremely adaptable to a wide range of soils. Prefers fertile sandy loam rich in organic compost (pH 5.0-7.0).

Plant in spring in a warm, sheltered location. Mulch highly to retain soil moisture, keeping mulch away from trunk bark.

Thrives in subtropical climates. Mature trees survive brief frost to -1°C, while young trees need protection.

Space trees 10-12 feet apart. Excellent for growing in large containers on warm, sunny patios.

Prone to fruit flies, scale, and whitefly. Spray young leaves with organic horticultural neem oil or wrap developing fruits.

Susceptible to Anthracnose and Guava Wilt. Avoid overhead sprinklers to keep leaves dry.

Harvest when fruits turn from light green to pale yellow, soften slightly to touch, and emit a highly sweet fragrance.

Common Diseases & Treatment

Guava Anthracnose (Fungal)

Symptoms: Circular, dark brown spots appear on leaves and fruit skins, expanding rapidly and causing fruit to rot and drop early.

Action: Prune for internal air circulation, avoid overhead watering, and spray organic copper fungicide proactively in spring.

Guava Wilt (Fungal)

Symptoms: Leaves turn yellow, curl upward, and drop prematurely. Branches die back, and the entire tree wilts rapidly within weeks.

Action: No cure exists. Purchase only certified wilt-free grafted stock. Maintain neutral soil pH and isolate infected trees.
