Re-potting is an essential skill for knowing how to take care of your lucky bamboo plant. First, gently and carefully remove the plant, roots included. You may need to dig around with your fingers to dislodge soil and free the plant from the bottom of the container. Prepare a clean container/pot in which to re-pot the plant. Use sterilized and sharp tools to peel back a third of the root mass, keeping only the closest roots intact to the plant. For water-based lucky bamboo, make sure the water is clean and has the correct nutrient content. For pot-based lucky bamboo, make sure the soil is loamy and acidic. Place the plant, firm the soil and water.
