Vietnam guava (Psidium guajava) is a tropical fruit tree that thrives in Southern California’s mild climate. With proper care, this tree can produce delicious fruit and add beauty to your landscape. Here’s a comprehensive guide to help you care for your Vietnam guava plant in SoCal:

Planting and Soil Requirements

1. Choose a sunny location: Vietnam guava trees prefer full sun to partial shade. Select a spot that receives at least 6 hours of direct sunlight.
2. Well-draining soil: Guava trees prefer well-draining soil with a pH between 5.5 and 7.0. SoCal’s soil can be alkaline, so consider adding organic matter like compost or mulch to improve soil structure.
3. Space correctly: Plant Vietnam guava trees 10-15 feet apart to allow for proper air circulation and growth.

Watering and Fertilization

1. Water regularly: Water your Vietnam guava tree regularly, especially during its first year. Aim for about 1 inch of water per week, either from rainfall or irrigation.
2. Fertilize: Feed your guava tree with a balanced fertilizer (10-10-10 NPK) during the growing season (spring-fall). Follow the manufacturer’s instructions for application rates.

Pruning and Pest Management

1. Prune regularly: Prune your Vietnam guava tree annually to maintain its shape, promote fruiting, and remove dead or diseased branches.
2. Monitor for pests: Keep an eye out for pests like aphids, whiteflies, and mealybugs. Use organic or chemical controls as needed to prevent infestations.

Protection from Frost and Heat

1. Protect from frost: Vietnam guava trees are sensitive to frost. Protect your tree from frost damage by covering it with a sheet or blanket during cold snaps.
2. Provide shade: While guava trees prefer full sun, they can benefit from shade during the hottest summer months. Consider providing shade using a shade cloth or tree shade.

Common Issues and Solutions

• Root rot: Overwatering can lead to root rot. Ensure good drainage and avoid overwatering.
• Pests: Regularly inspect your tree for pests and take action promptly if you notice any issues.
