what I think I learned about Lantana cuttings
I have a nice Lantana that I'd like to propagate. I heard that was drop-dead easy to make cuttings and get them to root. Did that last spring on new growth, with great success. Then during the summer, it didn't work. Did it this spring on new growth with great success.
I think it means that the stems that root well are the young and new ones. A stem that has been sitting out for months is not very rootable. The lesson is to root Lantana cuttings in the spring, when the new growth is bursting out.
But maybe it just doesn't like to root when it's hot?
