2. put the seed between 2 wet napkings in a vase until the root have at least 1 cm, the napkings will protect the seed from fungus, and give the seed enough water without overboarding.
4. plant the seed in a pot and cover it with 0.2cm of dirt or one of the same wet napkings. The pot should stay on a sunny place most of the time and with moist soil.
5. spray with vinegar diluted in water sometimes because mango is really fragile against plagues when its young.
pic related is one of the youngest mangos i have now, i live in a flat so i just plant them on a nearby mountain when they are ready (25cm).
Protect them from extreme weather btw.
