The plants should be transferred into larger pots and not kept as you received them. The pots are temporary to support the young plant for safe handling If left as is, the plant will continue to grow and become root bound and not enough soil to nourish the plant will kill it. I would recommend a pot at least 12 inches in diameter and six inches deep or as close as you can get it. It will grow and spread into a much larger plant, so do not concern yourself if you think the pot you select is too large Also give the plant a little dose of Miracle Grow (mixed with water) as per package instructions once in every two weeks..
