Here we will show you step by step how to transplant your sapling into the pot. The same process would apply to transplanting into the ground.
Carefully tear the plastic that the plant is sitting in. Use a blade if needed.
Fill the pot with some compost, so that the sapling when transplanted will reach just below the rim of the pot.
Take away all the plastic carefully, making sure that you don't disturb the soil that holds the roots.
Place the plant with the roots into the pot, and fill the sides with more compost.
Water the plant well. And you're done!
