my rubber tree was doing fantastic in its original plastic pot but now that i've repotted it (into a terra cotta pot) it has halted growth. i allowed it to dry out since and watered again but no change. i used regular potting soil. is this normal? its been 2 or 3 weeks. i feel like it was able to dry out more in the plastic pot but the terra cotta pot does stay damp for a while after watering. help! its my favorite plant!
