Step 1: Plant the seed into a fertile soil ( best in a flowering pot )
Step 2: Water it every day, every morning. Not too much water as it is still very fragile and does not need so much water. Probably 1 glass volume of water is enough for a seed/seedling.
Step 3: Please check if the soil is not very dry ( probably due to dry season ). If so, water it again with 1 glass volume of water.
Step 4: When you notice the plant has grown a firm stem, loosen the soil and carefully transfer it into your garden or any plot of land to let it grow into a tree. * Do not break its roots
Step 5: Check on it every day, make sure that the new soil is not too dry as well and this time, you can water more and more as it grows. If it grows half as tall as you, you can stop watering and it can independently find its water source in the soil or from the rain.
