Mango-Zill M-4 Mango by Zill's M4

Zill M-4 Mango Tree (Mangifera indica 'Zill M-4')

Taste: The Zill M-4 Mango is renowned for its exceptional taste and smooth, fiberless texture. The flesh is rich and creamy, with a vibrant orange color and a sweet, tropical flavor profile. It combines notes of pineapple, citrus, and peach, creating a complex and delightful eating experience. The fruit is juicy and aromatic, making it perfect for fresh consumption as well as for use in smoothies, desserts, and various culinary dishes. The skin is thin and typically yellow with a red blush when ripe.

Best Growing Environment: The Zill M-4 Mango thrives in warm, tropical to subtropical climates. It requires a well-drained soil, ideally a sandy loam, with a slightly acidic to neutral pH (around 5.5 to 7.5). This mango variety prefers regions with dry winters and warm, wet summers. The Zill M-4 Mango is sensitive to frost and cannot tolerate prolonged cold weather, making it best suited for areas where temperatures remain consistently warm. The tree should be planted in a location with good air circulation to reduce the risk of fungal diseases.

Common Names:

• Zill M-4 Mango
• Mangifera indica 'Zill M-4'
• This mango was a 'Keitt' seedling from the breeding program of Gary Zill in Boynton Beach, FL. The 'Gary' mango was its likely pollen parent.

Average Height: The Zill M-4 Mango tree typically reaches a mature height of 15 to 20 feet (4.5 to 6 meters), making it a relatively compact mango variety. This moderate size makes it suitable for home gardens, where it can be easily managed and harvested. With proper pruning, the tree can be kept even smaller, which is ideal for container growing or small spaces.

Growth Rate: The Zill M-4 Mango tree has a moderate growth rate. Under optimal conditions, it can grow 1 to 2 feet (30 to 60 cm) per year. The tree generally begins to produce fruit within 3 to 4 years after planting, depending on the care provided and the local growing conditions.

Sun Requirements: The Zill M-4 Mango tree requires full sun to thrive, needing at least 6 to 8 hours of direct sunlight daily. Adequate sun exposure is crucial for the tree's health, promoting vigorous growth and abundant fruit production. In areas with intense summer heat, some afternoon shade can protect the tree from excessive stress.

Cold Hardiness: The Zill M-4 Mango tree is not very cold-hardy and is sensitive to temperatures below 32°F (0°C). These can be successfully grown in 9b-11 if protected from frost while it is getting established. The tree should be planted in a protected area, such as near a south-facing wall, to provide some shelter from cold winds and frost.

Water Requirements: The Zill M-4 Mango tree requires regular watering, particularly during its first few years to establish a strong root system. The soil should be kept evenly moist but not waterlogged, as mangoes are susceptible to root rot. Once established, the tree can tolerate short periods of drought, but consistent watering during dry spells is essential for optimal fruit production. Mulching around the base of the tree helps retain soil moisture and regulate soil temperature.

Planting Guide:

• Site Selection: Choose a sunny location with well-drained soil. Avoid areas where water tends to accumulate, as mango trees are sensitive to waterlogged conditions.
• Planting Time: The best time to plant a Zill M-4 Mango tree is in the spring, after the last frost has passed. This timing allows the tree to establish during the warmer months.
• Spacing: Space trees about 15 to 20 feet (4.5 to 6 meters) apart to accommodate their mature size and ensure adequate air circulation.
• Planting Depth: Dig a hole twice as wide as the root ball and just as deep. Place the tree in the hole at the same depth it was growing in its nursery container, ensuring that the root flare is above ground level. Backfill with soil and water thoroughly.

Fertilizing:

• Spring: Begin fertilizing in early spring with a balanced, slow-release fertilizer, such as a 6-6-6 or 8-3-9 formula. This helps support new growth and flower development. Young trees should be fertilized every 6 to 8 weeks during the growing season.
• Summer: Continue fertilizing throughout the summer months. As the tree matures, reduce the frequency to 3 to 4 times per year. A fertilizer high in potassium (such as 0-0-50) can help enhance fruit quality and production.
• Fall: Apply a final round of fertilizer in early fall, before the onset of cooler weather. Avoid high-nitrogen fertilizers late in the season, as they can promote new growth that may be damaged by cold.
