Overview of the Keitt Mango Growing
The Keitt mango is a variety that is well-suited for commercial and home production in many areas. Originating in southern Florida in the 1930s, it has become a popular choice for its reliability and flavor.
Description
Keitt mango trees reach a height of 30–40 feet at maturity with an equal or slightly greater spread. Young trees have a compact, upright shape that opens into a vase shape as they age. The bark is green with a pebbly texture.
Fruit
Keitt mangoes are large, averaging 1-2 pounds each. Their skin is yellow with crimson blush when ripe. The flesh is fiberless, deep golden in color and very sweet, with a distinct “mango” taste. Ripening occurs from June to August in Florida.
Popularity
Due to their consistently large crops of excellent-quality fruit, Keitt mangoes are a top commercial variety. They are also a favorite of backyard growers and consumers thanks to their reliability and flavor.
Ideal Growing Climate for Keitt Mangoes
The ideal climate for successful keitt mango growing conditions includes tropical and subtropical temperatures year-round, along with sufficient rainfall and humidity.
Temperature
Keitt mangoes thrive in areas with hot, humid summers and warm winters above 45°F. Frost and freezing temperatures will damage or kill the trees.
Rainfall and Humidity
Keitt mangoes need consistent moisture through most of the year, along with average humidity levels above 60%. The ideal range is 40–75 inches of annual rainfall.
Growing Zones
Zones 9–11 are best suited, depending on specific microclimates. South and Central Florida, Southern Texas, Hawaii and Southern California provide excellent conditions for commercially productive Keitt mango orchards.
Homeowners in similar zones can also expect good results with Keitt mangoes, but should assess their own microclimate factors. Microclimates near large bodies of water moderate temperatures and increase humidity.
Site Selection
When choosing a planting site, consider the following ideal conditions for keitt mango growing:
Soil Type
Keitt mangoes prefer well-drained, sandy soils rich in organic matter. Clay soils should be amended. Avoid poorly-drained areas that stay wet after rains.
Sunlight
Keitt mangoes need full sun exposure, defined as at least 6 hours of direct sun daily. Trees will not bear fruit properly without sufficient sunlight.
Space Needs
Allow at least 30 feet between trees at maturity. Plant at least 20 feet from structures to provide room for the tree to reach its mature 30–40 foot height and width.
Other Factors
Shelter trees from wind when possible. Watch for microclimates prone to frost, as Keitt mangoes are vulnerable when young. Slope the ground away from trunks to avoid moisture issues.
Planting and Caring for Young Keitt Mango Trees
Follow these best practices for keitt mango growing conditions when establishing new trees:
Selecting Nursery Trees
Choose 1-2 year-old trees 8–10 feet tall for the fastest production. Check for signs of good health and ask about the nursery’s growing techniques.
Planting Method and Timing
Plant trees at the beginning of the rainy season while soil is still warm. Dig holes twice as wide as the root ball and only as deep.
Watering
Water new plantings thoroughly, 2-3 times per week for the first year, providing 1-2 inches total. As trees establish, water only as needed to prevent wilting.
Fertilizing
A balanced fertilizer high in nitrogen, phosphorus and potassium should be applied in spring and summer for the first 3 years. Compost is also beneficial.
Training and Pruning
Prune off suckers growing from below graft point. Train trees to an open center using stakes and ties to establish a strong structure.
Protection
Insecticidal soap or neem oil helps repel common pests when applied regularly. Control weeds within the dripline to minimize plant stress.
Maintaining Mature Trees
Follow these tips for ideal keitt mango growing conditions as trees mature:
Watering and Fertilizing
Water 1-2 times per week during hot/dry periods, providing 1 inch total. Fertilize in the spring and summer, cutting back in the fall and winter.
Pruning
Prune for air flow, Sunlight exposure and to maintain an open center. Remove suckers and diseased/damaged limbs. Thin excess new growth.

Pest and Disease Control
Common issues include scales, mites, anthracnose and powdery mildew. Prevent problems by maintaining tree health and hygiene. Spot-treat with approved controls as needed.
Propagation
For larger orchards, graft scions from top-performing trees onto rootstock to preserve traits. Air layering also works but takes longer.
Grafting and Training
Grafting to confer disease resistance or improve traits is an option. Train branches to achieve ideal structure and maximize harvests over time.
Harvesting Keitt Mangoes
Ripe Keitt mangoes indicate ideal keitt mango growing conditions have been met. Follow these harvesting best practices:
Ripening Signs
Watch for skins to turn yellow with red blush. Squeeze gently to ensure it “gives” a bit without feeling hard or unripe.
Handling and Storage
Refrigerate ripe fruit or allow to fully ripen at room temperature before refrigerating. Consume within a week.
Average Yields
Mature, well-cared-for trees may produce 400–600 pounds annually or more under ideal conditions like commercial settings.
Harvesting Tips
Twist mangoes off stems or use pruners. Make clean cuts just above natural seams and promptly refrigerate to prevent bruising.
