Seedling/Young Plant
4-8 weeks (or 6-12 months to reach transplant size)Small delicate plant with thin stems and emerging leaves; vulnerable to pests and environmental stress
Maintain consistent moisture without waterlogging. Provide shelter from strong winds. Use light fertilizer or diluted liquid feed every 2-3 weeks. Protect from temperatures below 50°F.
Vegetative Growth
6-18 monthsRapid stem and leaf development; plant establishes main framework and branches proliferate
Apply balanced fertilizer monthly (N-P-K ratio 10-10-10 or similar). Prune to encourage bushy form and strong branching. Maintain consistent watering. Remove any weak or crossing branches. Watch for early pest issues.
Pre-Flowering & Flowering
3-6 weeksSmall white or pale pink flowers emerge along branches and at stem tips; flowers are delicate with prominent stamens
Shift to higher phosphorus fertilizer (e.g., 5-15-10) to support flowering. Maintain regular watering without overwatering; inconsistent moisture can cause bud drop. Avoid heavy pruning during flowering. Ensure good air circulation to reduce fungal issues.
Fruit Development & Maturation
8-12 weeksSmall green fruits develop and swell; skin gradually transitions to pale yellow-green with pink blush, then deepening as ripeness approaches
Provide consistent water and balanced fertilizer. Thin fruits if extremely crowded to improve size and quality. Protect from strong winds to prevent fruit drop. Monitor for fruit flies and other pests. Support heavy branches if needed.
Ripening & Harvest
1-3 weeksFruits fully color up with distinctive pink interior visible under thin skin; flesh becomes softer and extremely fragrant
Stop heavy pruning to allow fruit ripening. Maintain moderate watering. Harvest ripe fruits to encourage additional flowering cycles. Overripe fruits attract pests; remove fallen fruit promptly. Prepare for post-harvest handling.

Harvest Tips
Harvest fruits when they yield slightly to gentle pressure and have a strong, sweet fragrance. For Thai Pink guava, wait until the skin develops a distinct pink-yellow hue and flesh shows pink coloring beneath the skin. Pick by gently twisting and lifting, or cut with pruning shears to avoid branch damage. Fruits do not ripen further after picking, so harvest only when fully ripe. Peak harvest typically occurs in summer and fall, though tropical regions may have multiple flushes annually.
Fun Facts

- 🌱 A single mature Thai Pink guava tree can produce hundreds of fruits per year under optimal conditions, making it one of the most productive tropical fruit trees.
- 🌱 Guavas have been cultivated for over 2,000 years and originated in Central and South America, though Thai Pink is a modern cultivar developed in Southeast Asia for superior sweetness and appearance.
