Before you plant a mamey sapote seed, you should know this is not the quickest road to harvesting your own fruit. When grown from seed, it can take mamey sapote 10 years to fruit and, even then, it is difficult to predict the fruit's quality. But if fruit is not an immediate concern, a mamey sapote tree can be a beautiful, low-maintenance addition to your lawn. Mamey sapote has few needs. When grown in a subtropical climate, a mamey sapote seed only needs full sun and well-draining soil. And with consistent watering and fertilization, it will soon grow to reach nearly 40 feet high.
Remove a 10-foot diameter circle of grass, being sure to remove the roots as well as the grass.
Dig a hole in the center of the circle that's 4 feet in diameter and 4 feet deep.
Mix half of the soil you excavated from the hole with an equal amount of peat moss and aged compost.
Backfill the hole with your new soil mixture and tamp the soil down with your hands to remove any air pockets.
Plant your mamey sapote seed in the center of the re-filled hole so the tip sticks 1/2 inch out of the soil.
Spread a 4-inch layer of bark mulch inside your grassless circle but do not place any mulch within one foot of the newly planted mamey sapote seed.
Water so the soil is quite moist but not soaked to the point of forming puddles.
Wait two to four weeks for your mamey sapote seed to germinate.
