When do we need to repot plants? Usually my practice will be after bought from nursery, I will let them in their original pots at home for at least a few days before repotting them. Let's them to get use to the new environment first before repotting them to a prettier pot of my choice.
Step 1: choose the pot (you may read how to choose the right pot here).
Step 2: Gently press/squeeze at plastic nursery pot to loosen the soil from the pot.
Step 3: Remove it from its original pot and gently remove the soil as much as I can, please try your best not to damage its roots.
Step 4: Prune some roots if you think needed.
Step 5: Place some of your medium aka soil of your choice depending on the types of plants at the bottom of the pot.
Step 6: I will add some based fertilizer at the bottom of the pot.
Step 7: place the plant in and slowly adding in more medium (soil) and make it even.
Step 8: plant might get shocked after repotting. Watering it after repotting and refrain from too frequent watering even it might look sad or wilted.
Tadaa.. you are set!
