The Glenn Mango (Mangifera indica 'Glenn') is a fast growing, semi-dwarf tropical tree that produces delicious mangoes without taking up too much space. This full sun loving tropical tree is best suited for USDA growing zones 9-11 but can be successfully container grown for zones 4-11. When grown outside in more tropical areas, the mango can take cold snaps that drop as low as 30 degrees. One of the other advantages of the Glenn is that it is a self-fertile tree which means you can get fruit with just the one but have a more bountiful harvest with two nearby one another.

Location: Direct sunlight and lots of warmth are a mango’s best friend. When choosing a location, whether in a container or in the ground, try to choose a place with the most hours of sunlight possible. If the container will be indoors, place it near a window. When choosing a location in the ground, avoid low areas or areas that tend to flood. Mangoes like to be on higher, drier ground for better drainage.

Planting Directions (in ground):
1) Once you have chosen the best spot for your tree, dig a hole that’s three times as wide as the pot your tree came in, and just as deep. Take a pitchfork or shovel and loosen the soil around the sides of the hole. Remove any debris, like dirt clumps, grass, or rocks.
2) Carefully remove the tree from its plastic container and gently comb through the root ball to free up the roots.
3) Position your tree in the hole, and make sure that it’s level with the surrounding ground, and that it is standing straight up.
4) Back fill the hole and tamp down with your hands as you go to avoid any air pockets from forming.
5) When you have finished, water the planting site generously and then broadcast mulch around the base to conserve soil moisture and combat any competing weeds that try to grow around the tree. Avoid letting the mulch touch the trunk of the tree or fungus and rot may set in.
*Tip: Mangoes prefer loose sandy soil that is on the acidic side. To achieve this, mix a little sand into the hole along with a bag of acidic planting mix. The acidic planting mix will have lots of potassium to make your mangoes taste more flavorful!

Planting Directions (potted):
1) Select a pot that has multiple drainage holes in the bottom and is 2 sizes bigger than what the mango initially arrived in.
2) Fill in the open pot space around the root system with a quality potting mix that has a light acidic side to it.
3) Tamp down the potting soil as you would if the tree was planted in the ground to prevent any air pockets from forming.
4) Water the mango well so the soil has been evenly moistened and allow the soil to settle.
5) Ensure the tree is in a very sunny location as this tree does need full sun to thrive. 6-8+ hours each day is best for the exposure.

Watering: Mangoes are rarely ever thirsty but for their first two weeks of establishing, they MUST be watered every day. The most common mistake that gardeners make with this tree is over watering. For the first 6 weeks after planting, water only once every three days. After that you can back off to once a week and then every two weeks over the winter. During the hot months of summer your tree may need a bit more water than over the spring or fall. Potted mangos will need watering on a daily basis as well at first. After the 1st two weeks, water whenever the top 2 inches of the soil is dry to the touch.

Fertilizer: DO NOT USE CHEMICAL FERTILIZER! Mangoes are easily burnt by fertilizers high in ammonium nitrate. The best fertilizer is a natural, organic one with mycorrhizal fungi and beneficial bacteria. A little gardening secret that Indians used to do that works wonders on mangoes, bury a fish touching the roots of your plant. The fish contains lots of nutrient crucial to a mango in its first years. Potted mangos will benefit from a balanced fertilizer formula such as a 10-10-10 while actively growing. Cut back on feeding the tree nitrogen in flowering period, instead provide a boost of phosphorus and potassium.

Weed Control: Weeds steal vital nutrients from the plants around them. The best way to keep weeds at bay and help your tree grow is with pine bark. Placing a one-inch thick layer three feet around the base of your tree will stop the weeds. Also another bonus is as the pine bark decomposes, it will raise the acidity of your soil naturally!

Pruning: On a mango tree the fruit forms at the ends of the branches. Because pruning causes the tree to put on more lateral branches, pruning will give you more mangoes. Mangoes are very forgiving so don’t be afraid to prune them, but don’t go crazy and scalp the thing. Your goal when pruning should be to form an open crown so that light and air can penetrate to the middle of the tree. This will reduce the risk of fungus and diseases. The best time of year to prune your mango tree is right after the harvest; but in cooler areas you will be better off pruning just before the mango starts to flower. Some light pruning of the potted mango is good. These trees do not typically require a lot of pruning, just be sure to remove dead, damaged or diseased branches to help control the tree’s shape.

Pollination: Mangoes are excellent self-pollinators and will produce fruit by themselves. If you want to double your yield it is recommended to plant a second mango and encourage bees and other pollinators to come to your trees.
