How to Plant a Mango Seed

1. 1
   Check your climate zone. Mangos are native to the hot, humid tropics of Asia and Oceana. Outside of that area, mango trees grow well in USDA hardiness zones 9B or above. In cooler areas, mangos can still be grown in containers and brought indoors during freezing weather. ^[1]

   • The Cogshall mango variety is a popular choice for growing indoors, and can be kept permanently at 8 ft (2.4 m) tall with regular pruning. Even smaller dwarf varieties exist for people with limited space. ^[2]
2. 2
   Find a parent mango tree. The best way to make sure you get a seed that will grow well in your area is to find a parent tree nearby. A nearby tree that produces good fruit will give you a seed that's the right variety for your climate. If you live in a warm climate with mild winters, you can probably find a healthy mango tree in your area. ^[3]

   • If you can't find a mango tree, you can order seeds or buy them in a shop. Make sure to choose a variety that is known to grow well where you live. ^[4]
   • You can also try to plant a seed from a store-bought mango. However, it will be a lot more difficult to make sure the seed stands a chance to survive in your climate, especially if the mango traveled to your grocery store from another state or country. Still, it's worth a try!

   Check the seed to see if it's viable. Cut away the mango's flesh to find the seed husk inside. Carefully cut away the husk to reveal the seeds. A healthy mango seed will look tan and fresh. Sometimes seeds shrivel up and turn grey if they're exposed to cold temperatures, and if this happens, the seeds aren't usable.

   • Slice both cheeks off as close as possible to the seed: Place a cheek in the palm of your hand, carefully scoring the flesh side of the cheek, both ways, approximately 2cm/1 inch each way. Then turn the cheek up, exposing cubes of delicious mango flesh. Eat as is from the skin, or scrape off with a spoon, directly into a bowl.
   • You might want to wear gloves when handling the seed. Mango seeds produce sap that can cause skin irritation.

   Choose a method for preparing the seed. You can use either the drying method, or the soaking method, as noted below. The soaking method reduces germination time by one to two weeks, but increases the risk of mold.

Drying the Seed

1. 1
   Dry the seed thoroughly with a paper towel. Place it in a sunny and airy dry place for around 3 weeks. After this time, with one hand, try to crack open the seed, trying not to let it slip in half; you just need to slightly separate the two halves, and leave for another week.
2. 2
   Place fertile, well drained soil in a container. Dig a small hole approximately 20cm/8 inches deep. With the belly button of the seed face down, push the seed in. ^[5]
3. 3
   Water in well, and keep the water up every day, or every other day, depending on the soil. After around 4 to 6 weeks, you will have a mango tree / seedling about 100mm to 200mm high. Depending on the variety of mango you earlier devoured, it may be a deep purple, almost black, or a bright vibrant green.
4. 4
   Grow the seedling until it has established a good, healthy root system. Many people grow mango trees indoors for one to two years before planting them outside.

Soaking the Seed

This alternative to drying is one to two weeks faster. There is a higher risk of mold, so you may not want to try this if you only have one seed.

1. 1
   Scarify the seed. To "scarify" is to slightly abrade the outside of the seed, making it easier for the seed to germinate. Carefully make a small cut in the mango seed or rub the outside of the seed with sandpaper or steel wool just enough to break through the outer skin of the seed.
2. 2
   Soak the seed. Place the seed in a small jar of water, and place the jar in a warm place such as a cupboard or on a shelf. Soak the seed for 24 hours.
3. 3
   Remove the seed from the jar and wrap it in damp paper towels. Place the wrapped seed inside a plastic bag with one corner cut off. Keep the towels moist and wait for the seed to sprout - it usually takes 1 to 2 weeks. Make sure to keep the seed in a warm, moist place to help it germinate.
4. 4
   Prepare a pot for the seedling. Start your seedling's growth in a pot. Choose one big enough to hold the seed and fill it with a mixture of potting soil and compost. You could plant the seed directly in the ground, but planting it in a pot first allows you to control temperature exposure during the vulnerable early stage of growth.
5. 5
   Sun harden the seedling. Place the pot outside in partial sun; this allows the seedling to get used to the sun, or harden, before being transplanted to its final place in the full sun.
