Does anyone have tips to improve/speed up root formations on leaf pullings from sundews and VFT's? I hear that rooting hormones can be applied. Are there other ways?
Not really. There's no magic to getting a plant to root other than appropriate lighting, moisture, possibly adding some rooting hormone to help it along, and of course time and patience! ;)
I haven't done VFTs yet but Sundews are easy, at least Spatulata and Adelea for me.
I don't use hormones on them, I usually put a clear cover over the pot/container and wait.
