Anita, how the heck are you going to get those Centaura seedlings safely out of the container. IF too much growth with loss of roots when you get them out, they won't stand much chance. I would trim them back after you transplanted them. That way those roots left won't have to support so much green growth while getting established and growing new roots. I always do that when transplanting or dividing.

Below is a transplanting hormone solution to help plants get established quicker. It is diluted with water. I use it on everything and it is great. Walmart and Home Depot have it.
