Mangos are delicious, but mango trees cannot be grown in every yard. Mango trees are native to Southeast Asia, and to thrive and fruit, they must be grown in a similar tropical or subtropical climate. In the United States, that translates to growing zones 10 and 11. Before you plant, contact your local county extension office or garden center expert to discover if your yard is a suitable place for a mango tree. Once you get the green light, invest in a quality, certified, disease-free mango sapling. This is the best way to guarantee tasty, abundant mango crops.
Remove the grass and plant roots around the planting area in a 3- to 10-foot diameter.
Dig a hole that is three times the diameter and depth of the container that the mango is currently growing in.
Mix the excavated soil with compost in a 1-to-3, compost-to-soil ratio.
Remove the mango tree from its container. Loosen the roots by pulling them gently away from the root ball with your hands. Prune any roots that are broken, withered and dead or mushy and diseased.
Plant the mango tree in the hole so that it is at the same level in the ground as it was in the container. Backfill the hole with some of the amended soil first so the mango tree's root crown is an inch or so above the surrounding soil. Then fill the soil in around it and compact it a bit by walking over it. Do not cover the top of the mango tree's roots with more than 1 inch of soil.
Water the planting area until the soil is moist to the depth of the mango's roots. Run a slow hose near the base of the tree. If water puddles at the surface, turn down the water. Use a wooden dowel to measure the moisture depth every half-hour or so. Continue to keep your mango tree consistently moist to this depth until it establishes itself and produces new growth. Check the moisture depth daily (twice daily when the temperatures are high) and water when necessary.
