Hi all! I have an incredible pepperomia that I have split a few times and all parts are doing well. However, I had a loose leaf that I tried to propagate. I placed it in water until roots grew and then moved to the soil. A light tug tells me its definitly rooted in the soil, but the look of the leaf has not changed at all. Is that expected, or should this be growing more? Is there anything I can do to help it grow? Thank you!
