Narrowleaf Guava (Psidium striatulum)
Regular price $24.95Narrow Leaf Guava is a beautiful small tree in the Myrtle family (Myrtaceae), native to northern South America. It is known for its attractive foliage, deliciously sweet and fragrant fruit, and for its medicinal properties.
This little tree grows to 10' high and wide with slender leaves that emerge red or pink and mature to dark green. White flowers grace the tree in the spring, followed by plentiful 2" to 3" round or oval yellow fruits. The pink pulp is a delightful treat eaten out-of-hand or made into jams, jellies, ice cream sorbets, beverages, or added fresh to salads or cereals. The fruit is also an excellent source of vitamin C, fiber, and antioxidants, and traditional medicines use the leaves to treat diabetes, pain and wound healing, and stomach and intestinal problems.
Narrow Leaf Guava grows in full sun in well-draining soil and does need to be watered frequently until it's established. It is an outstanding addition to a home garden or in a container, but will not tolerate freezing temperatures and will only grow in subtropical and tropical areas.
Our Narrowleaf Guava fruit tree plants are shipped in our Medium 4" biodegradable coconut coir planters that can be planted directly in the soil, promoting strong root growth and ensuring an eco-friendly start.
Climate and Soil Requirements
- Climate: Narrowleaf Guava thrives in warm, tropical, and subtropical climates. It is best suited for USDA hardiness zones 9-11. While it prefers temperatures between 70-85°F, it can tolerate short periods of frost.
- Soil: Prefers well-draining, loamy soil rich in organic matter. A slightly acidic to neutral pH (5.5-7.0) is ideal. The plant can tolerate poor soils but performs best in fertile, well-amended ground.
Planting
- Location: Choose a sunny location with at least 6-8 hours of direct sunlight daily. Ensure the site has good air circulation to prevent fungal diseases.
- Soil Preparation: Amend the soil with compost or well-rotted manure to improve fertility and drainage. Ensure the planting site is free of weeds.
- Planting Time: Plant young trees in the spring after the last frost, or in the fall in milder climates. If growing from seed, start seeds indoors 8-10 weeks before the last frost and transplant when seedlings are sturdy.
- Spacing: Space trees 10-15 feet apart to allow adequate room for growth and air circulation.
Watering
- Establishment Phase: Water regularly to keep the soil moist but not waterlogged during the first year. Consistent moisture is crucial for young plants.
- Mature Plants: Once established, Narrowleaf Guava is somewhat drought-tolerant. Water deeply and less frequently, allowing the top inch of soil to dry out between waterings.
Sunlight
- Full Sun: Ensure the plants receive at least 6-8 hours of direct sunlight daily for optimal growth and fruit production.
Fertilizing
- Growing Season: Apply a balanced, slow-release fertilizer in early spring as new growth begins. Supplement with a high-potassium fertilizer during the fruiting period to enhance fruit development.
- Frequency: Fertilize every 4-6 weeks during the growing season. Reduce feeding in the fall and avoid fertilizing in winter.
Pruning and Maintenance
- Routine Pruning: Prune in late winter or early spring before new growth begins. Remove dead, diseased, or weak branches to maintain the tree's shape and improve air circulation.
- Fruit Production: Light pruning helps encourage new growth and increased fruit production. Avoid heavy pruning, which can reduce yields.
Pest and Disease Management
- Common Pests: Monitor for pests such as aphids, scale, and fruit flies. Use insecticidal soap or neem oil to control infestations. Encouraging beneficial insects can also help manage pests.
- Diseases: Watch for signs of fungal diseases such as anthracnose and powdery mildew. Ensure proper spacing, good air circulation, and avoid overhead watering to reduce disease risk. Apply fungicides if necessary.
Harvesting Fruit
- When to Harvest: Fruits are ready to harvest when they are fully colored and slightly soft to the touch. They should easily detach from the tree.
- Usage: Enjoy fresh, in salads, or use in cooking and baking. Narrowleaf Guava is particularly sweet and aromatic, making it perfect for preserves, jellies, and desserts.
Winter Care
- Outdoor Plants: In regions prone to frost, protect trees with frost cloth or burlap during cold snaps. Mulch around the base to insulate the roots.
- Indoor/Container Plants: Move containers to a sheltered location or indoors during the winter. Maintain a consistent temperature and humidity level.
