Hello, I have an incredible trumpet vine that has grown leaps and bounds, like I've never seen:
However, I've never been able to propagate it.
Here's my setup. I plant in a mixture of peat moss and perlite and place under plant light next to a window. I cover with plastic wrap but not tightly so there's room for air circulation. I water only when the top inch has dried out:
I get my cuttings but cutting the end of a branch and trim the leaves from the part that goes into the dirt. I wet and tap it in rooting hormone before sticking in a hole and then squeeze the container slightly.
In the photo below, the back row contain cuttings from Snail vine and they are doing fine. The front row are my trumpet cuttings. The ones in the right container already dead and one in the left container - which was from middle of a ticker stem - seems to be on its way dying.
Can you tell me please what I'm doing wrong? Do I need a heating pad? I am guessing temperature not an issue because I see water evaporation on the plastic cover after I water. I also thought perhaps this is just the wrong time of the year to do this, even though I'm in Los Angeles. But the vine doesn't seem asleep and is growing. Any tips would be much appreciated and thank you in advance.
