Keitt Mango Tree — the One That Saves the Best for Last
We have a soft spot for Keitt. Most mango varieties ripen in a rush through May and June — and then the season quietly ends. Keitt doesn’t do that. It holds its fruit back until late summer, so when every other mango is finished, yours is just getting sweet. There’s something satisfying about walking outside in August and picking a ripe mango while the neighbors’ trees stand bare.
And the fruit is worth the wait. Keitt mangoes run one to four pounds, with skin that stays mostly green even when ripe — so you judge readiness by a gentle squeeze at the stem, not by color. Inside, the flesh is nearly fiber-free. You can scoop it straight out with a spoon, like custard. No stringy bits.
This one has a good story, too. Keitt was found as a seedling on a Homestead, Florida property in 1939 and went on to become the workhorse mango of South Florida’s orchards. It’s also a semi-dwarf with an open, easy canopy — one of the few full-size mangoes that settles honestly into a large pot.
How to Help It Thrive
Keitt is happiest with six or more hours of direct sun and soil that drains freely. Like all mangoes, it dislikes wet feet — water deeply, then let the top few inches of soil dry out before you water again. In Zones 10–11 it’s right at home in the ground, and mature trees can briefly take near 25°F while young trees want to stay above 30°F. North of Zone 10, a 20–25 gallon pot and a sunny indoor spot for winter will keep it happy for years.

What to Expect as It Grows
Your Keitt arrives as a grafted tree about 2–3 ft tall, already past the fragile seedling stage. Grafted trees usually begin bearing in 3–5 years — far sooner than a seedling, which can take a decade or never fruit at all. Once it settles in, Keitt is a heavy bearer.
