After potting from a cutting, when is the proper time to put it in the ground
Wait until it shows signs of vigorous new growth and not just a few new leaves. There should be a significant root system, that is, roots are visible when sliding the plant out of its container. Conditions outdoors are very stressful to a plant that has been treated with TLC indoors. Don't forget to harden it off for 1-2 weeks, especially if it is going into full sun.
