Make sure you give the cuttings high humidity with a plastic bag or something. When my cuttings are in low humidity the leaves quickly droop. I've lost a few cuttings that way. Also make sure you cut the bottom leaves off from your cuttings just leaving the growth shoot and very top leaves.

Then plant put them in small cell pots and don't water them to frequently or the stems will rot. Water them as much as you do a regualr Salvia. Especially watch when misting. Try to treat the bottom with rooting powder also it seems to speed things up quite a bit.

Heres a pic of my latest cuttings. I took them a little over a week ago.
