How To Plant Mango Seed In A Pot. 1 how to grow mango seed in the water? Water your plant with lukewarm water whenever you see the soil is a bit dry.
Then place the seed, rounded side up, in a dish of water. The seed should be fully covered with soil. Leave the mango seed in the water until it starts to sprout.
You can also germinate the mango seed by the paper towel method.
Firm the soil down with your hand and water the tree well. This can take anywhere from 1 to 3 weeks. I like to sow the seed in a pot and then transplant the seedling to a larger pot or into the ground. Because the tree plus the pot and dirt will be heavy and you want to be able to move it around, place the pot atop a plant caster stand.
