Guava Care

Site & Planting

• Sun: Plant in full sun for best growth and fruit production.
• Soil: Guava tolerates many soils but performs best with good drainage.
• Planting: Set at container depth and keep the trunk flare above surrounding soil.
• Cold: Young guava trees are cold-sensitive; use a protected site and prepare to cover small trees during freezes.

Watering & Mulch

• Establishment: Water at planting, then frequently during the first weeks while the root system establishes.
• Young trees: During prolonged dry weather, young trees may need watering about twice weekly depending on soil drainage.
• Mature trees: Irrigate during extended drought, especially from bloom through fruit development.
• Mulch: Use 2–6 inches of mulch over the root zone but keep it 8–12 inches away from the trunk.

Fertilization & Pruning

• Fertilization: Feed young trees lightly and regularly during active growth; mature trees generally need fewer applications.
• Micronutrients: High-pH soils can cause iron and micronutrient deficiencies; correct based on symptoms and soil conditions.
• Pruning: Guava tolerates pruning well. After harvest, shorten overly vigorous shoots and maintain an open, manageable canopy.
• Fruiting: Because guava flowers on new growth, strategic pruning can stimulate additional flowering flushes.

Fruit Protection

• Fruit fly: Caribbean fruit fly is a major Florida guava pest. Bagging young fruit can greatly reduce infestation.
• Sanitation: Remove fallen and overripe fruit promptly.
• Harvest: Harvest as fruit softens and develops its mature skin color and aroma.

Florida note: Common guava is considered invasive in parts of Florida. Check current local guidance for your county and prevent unwanted spread.
