are very easy to grow plants but repotting any plant can cause issues if it is not done correctly. I usually advise leaving plants in the original container but my preference is always for a pot with drainage holes. Without a way for excess water to escape the soil, moisture builds up at root level, causing the roots to suffocate and rot.
If you decide to repot, it's best to use a container the same size as the original pot, or as close to that size as possible, leaning on the idea that a little smaller is better than larger. Gently lift the plant from it's current non-draining pot and place some of the original soil into the bottom of the new pot. Sit the plant down onto the soil, making sure that the plant is at the same level as it was previously planted, filling in around the sides of the plant with additional soil and gently tamping it down to secure the plant in place. Place it in a brightly lit area but do not subject it to full sun. I would wait at least a week before watering, to allow the plant to acclimate to it's new pot.
