Those who love exotic species cannot ignore the mango. We explain how to plant a mango seed and grow your own mango tree from it.
Similar to an avocado kernel, a mango kernel is relatively easy to plant in a pot and grow into a pretty little tree. In the tub, the planted kernel of the mango (Mangifera indica) grows into an exotic mango tree in lush green or elegant purple. Although mango trees you have grown yourself do not bear any exotic fruits, as the temperatures in our latitudes are too low for that, the mango tree you have planted yourself is a great highlight for every living room. This is how you grow your own mango tree.
Choose a very ripe organic mango from the fruit trade or seeds from specialist shops. Cut the pulp from the stone and let it dry a little. The seeds are then exposed with a sharp knife. To stimulate it to germinate, it is either dried or soaked. The mango kernel with root and seedling is placed about 20 centimeters deep in a pot with a mixture of soil and sand and compost. Keep the substrate evenly moist.
Which mango is suitable for planting?
Most edible mangoes from the supermarket cannot be used for self-cultivation, as they have often been treated with anti-germ agents. The mangoes are also harvested and cooled very early because of the long transport routes, which is not particularly good for the seeds inside. If you still want to try to plant the pit from a mango, you can look for a suitable fruit in the fruit trade or use an organic mango.
But be careful: In their tropical homeland, mango trees with a height of up to 45 meters and a crown diameter of 30 meters are real giants! Of course, the trees are not that big in our latitudes, but it is still advisable to buy suitable seeds from specialist shops. For planting in pots, we recommend seeds of the American cultivar ‘Cogshall’, for example, because it only grows to a little over two meters. Different dwarf mango species can also be planted well in the tub.
How do you prepare the mango stone?
Cut the flesh of very ripe mango and expose the large, flat stone pod. Let it dry a little so that it is no longer so slippery and you can pick it up easily. If you can now hold on to the core, use a sharp knife to carefully pry it open from the tip over the long side. Attention risk of injury! A kernel appears that looks something like a large, flattened bean. This is the actual mango seed. This should look fresh and whitish-green or brown. If it is gray and shriveled, the core can no longer germinate. Tip: Wear gloves when working with the mango, because the mango peel contains substances that irritate the skin.
How do you stimulate the mango kernel to germinate?
One way to stimulate the kernel to germinate is to dry it out. To do this, the mango kernel is dried thoroughly with a paper towel and then placed in a very warm, sunny place. After about three weeks, it should be possible to push the core open a little. Be careful not to break the core! When open, the mango kernel is allowed to dry for another week until it can be planted.
With the wet method, the mango kernel is slightly damaged at first, that is, it is carefully scratched with a knife or gently rubbed with sandpaper. This so-called “scarification” ensures that the seeds germinate quickly. After that, the mango kernel is placed in a container with water for 24 hours. The core can be removed the next day. Then you wrap it in damp paper towels or a wet kitchen towel and put the whole thing in a freezer bag. After one to two weeks of storage in a warm place, the mango kernel should have developed a root and a sprout. It is now ready to be planted.
Planting mango kernels: this is how it works
Conventional potted plant soil is suitable as potting soil. Fill a not-too-small plant pot with a mixture of soil and sand and some ripe compost. Place the core with the roots down and the seedling up about 20 centimeters deep in the planter. The core is covered with earth, the seedling should protrude a little from the top. Finally, the planted mango kernel is poured on thoroughly. Keep the substrate evenly moist over the next few weeks. After about four to six weeks there will be no mango trees. If the young mango tree has well-rooted the nursery pot, it can be moved to a larger pot.
After about two years of growth, the self-planted mini mango tree can already be seen. In summer you can put it in a sheltered, sunny spot on the terrace. But if the temperatures drop below 15 degrees Celsius, he has to go back into the house. Planting out the heat-loving exotic in the garden is not recommended. Not only because it cannot stand the winter temperatures, but also because the roots of the mango tree quickly dominate the entire bed and displace other plants.
