Known for its sweet-tart flavor and reddish-pink flesh, the Red Grapefruit tree is a perfect choice for those looking to add a burst of color and flavor to their landscape.

Key Features of Red Grapefruit Trees

1. Fruit: Red Grapefruits are round to slightly oblong with stunning reddish-pink flesh, known for their sweet-tangy taste and high vitamin C content. They are perfect for fresh eating, juicing, and adding to salads and desserts.

2. Blossoms: Spring brings a display of fragrant white blossoms that add an ornamental quality, filling gardens with a pleasant scent.

3. Foliage: With glossy green leaves, Red Grapefruit trees provide visual appeal and shade, enhancing any garden’s aesthetic.

Growing Red Grapefruit Trees in Arizona

1. Variety Selection: Choose heat-tolerant varieties ideal for Arizona’s climate, such as ‘Ruby Red,’ ‘Star Ruby,’ or ‘Rio Red’ for optimal growth and fruit production.

2. Planting Location: Select a sunny location with well-drained soil to ensure healthy roots and abundant fruit. Full sun exposure is key for citrus trees to thrive in Arizona.

3. Soil Preparation: Enrich the soil with organic matter to improve water retention and nutrient levels. Slightly acidic soil is ideal for Red Grapefruit trees.

4. Watering: Arizona’s hot, dry climate requires consistent watering, especially in summer. Use a drip irrigation system to target the root zone directly, being careful to avoid overwatering to prevent root rot.

5. Fertilization: Apply a citrus-specific fertilizer as recommended to promote healthy growth and abundant fruit.

6. Pruning: Regular pruning helps shape the canopy for better sunlight penetration and airflow, as well as removing any dead or diseased branches.

7. Pest and Disease Management: Watch for pests like aphids and citrus leafminer and take timely pest control measures when necessary.

8. Harvesting: Harvest Red Grapefruits when they reach their vibrant reddish-pink color, indicating full ripeness. Enjoy them fresh, juiced, or in your favorite recipes.

• Spacing: Space trees 12-15 feet apart to allow for optimal growth and air circulation
• Planting Depth: Plant at the same depth as the root ball, ensuring the top of the root ball is level with the surrounding soil surface
• Support: Red Grapefruit trees may need light staking during early growth but become self-supporting as they mature

Watering Guide:

Watering After Planting:

• Initial Watering: Water thoroughly immediately after planting to saturate the root ball and surrounding soil
• Frequency: Water every 5-6 days for the first 2-3 weeks to help establish the root system
• Watering Amount: Provide 3-4 inches of water per session for deep watering

When is the Plant Established?

• Timeframe: Red Grapefruit is considered established after 6-8 months when the roots have spread into the surrounding soil

Watering Once Established:

• Summer: Water every 7-10 days during the hotter months. If temperatures exceed 100°F, increase watering to every 5-7 days. Provide 3-4 inches of water per session.
• Winter: Water every 3-4 weeks during the cooler months, depending on rainfall.

Drip Irrigation Setup:

• Placement of Emitters: Place the drip emitters 18-24 inches away from the base of the tree for deep watering of the root zone
• Flow Rate: Use emitters with a flow rate of 2-4 gallons per hour
• Number of Emitters: 2-3 emitters per tree for even watering distribution
• Adjusting Frequency: In summer, increase watering frequency to every 5-7 days. In winter, reduce to every 3-4 weeks
