Psidium guajava, commonly known as guava, is a fast-growing, evergreen to semi-deciduous small tree or large shrub native to tropical Mesoamerica. It forms a low, spreading canopy with smooth, mottled bark and opposite, aromatic leaves that release a resinous scent when crushed. Fragrant white flowers with prominent stamens give way to round or pear-shaped fruits whose thin rind encloses sweet to tart, musky flesh in shades from white to deep pink, rich in vitamin C and edible seeds. Guava is adaptable, tolerating varied soils and periodic drought, and begins bearing heavily within 2–4 years. It thrives in warm, frost-free climates but can be container-grown and pruned to size in subtropical zones. Beyond fresh eating, the fruit is prized for juices, jams, and confections, while young leaves are used in traditional herbal infusions. Its resilience, productivity, and culinary versatility make guava a rewarding fruit tree for home gardens and small orchards.

How to care for Guava
Water
Keep soil evenly moist while establishing (first 6–12 months), watering deeply once or twice weekly depending on heat, wind, and drainage. Mature guavas tolerate short dry spells but yield best with consistent moisture, especially from flowering through fruit enlargement. In containers, water when the top 2–3 cm are dry; let excess drain and never leave pots in saucers. Mulch to reduce evaporation, and avoid chronic waterlogging, which encourages root rot and nutrient lockout.
Light
Provide full sun for 6–8+ hours daily to maximize flowering and fruit sweetness. Guava tolerates light, open shade, but dense shade sharply reduces bloom and yield. Choose a warm, wind-sheltered site; reflective heat near walls aids ripening in marginal climates. Indoors or in greenhouses, use high-output grow lights to deliver bright, day-long light, keeping fixtures 30–60 cm above the canopy and adjusting as plants elongate.
Nutrients
Feed during active growth (spring through late summer) with a balanced fruit-tree fertilizer emphasizing moderate nitrogen and ample potassium (e.g., around 8-3-9). Incorporate compost or well-rotted manure annually to boost organic matter and supply micronutrients (Fe, Zn, Mn, B). For containers, use slow-release granules every 10–12 weeks or supplement biweekly with half-strength liquid feed. Reduce nitrogen as flowering begins to favor fruit set. Overfertilizing promotes leafy growth and bland fruit.
Temperature
Best performance is between 23–30°C. Trees are frost-sensitive; young growth is injured near 0–2°C and defoliation can occur below −2°C. In hot climates they tolerate 35–40°C if well irrigated and mulched. Grow outdoors in USDA zones 9b–12; elsewhere, overwinter containers in bright, cool (10–15°C), frost-free quarters. Warm days with mild nights favor flowering and fruit quality. Protect from cold snaps with covers and trunk wraps.
