Hello! I bought a burgundy ficus decora recently and I am trying to figure out how to help it grow successfully. Currently the stems are thin, along with the new growths. The new growths are also folding at weird angles. There are also 5 trees in one 4 inch pot. My initial thought was to split the tress into two pots(3 and 2) since they are still small. My question is what should I do with them to make sure they grow successfully? Thank you!
