Potting up salvias and recipe for good planting mixThis information is from GardenWeb Salvia Forum member:
The dark coloration you are experiencing is due to loss of root because the plant roots are being kept just too damp. The miracle gro soil mix is NOT the best for Salvias. Salvias require fast draining highly aerable soil mixes and are probably best in soil mixes that are not enriched by fertilizer additives.
For a mix use either mix for Cactus plants-though avoid any such mix if it has peat moss or sphagnum in it. Your best bet is to mix your own. Try the following:
2 parts river sand
1 part granitic gravel
2 parts acid loving plants soil mix
and 1 part either hard wood leaves such as pin oak or fine grade bark (such as ground cover bark)
What is important is that the plant should be underpotted.
Stuff the roots into a pot that is only a little larger than the existing root ball-but shake off any of the old soil you can but do not disturb the roots physically.
Pour in the new mix dry. water. add more dry as it will settle and water again and repeat until the soil level is at the base of the plant's stem(s)
Put it outside with 50% light and as long an exposure as possible (4 to 6 hours).
Salvisas enjoy the sun and the heat. Do NOT water regularly. but only when the pot feels much lighter even though the plant does not appear to be slightly wilted. Sometimes I wait until the growing stem start to droop a bit before watering.
Currently I grow Salvia apiana in a pot. Can supply an image if you wish to see it.

Propagation of S. greggi by cuttings by dufresnerich dufresne z7 NC (My Page) on Tue, Apr 18, 06 at 20:56
The simplest method is to take cuttings down to green wood, not tip growth with weak stems, or stems with bark forming. I use the "asparagus" method to determine the point to cut the stem. If you grasp the stem below the point where bark forms, then bend the top back, you should see the area where the tip growth stops being supple and stiffens. This is the area where you make the cut.
The bottom third of the cutting will have its leaves stripped off. It is good to have a node or two under the rooting medium, since side shoots will start from these points and allow the plant to form secondary leader stems. If the plant gets sheared at ground level, it will have a much better chance to send out new growth.
The stock plant should be in a rapid growth stage for optimal cuttings. If it is dormant, the cuttings will take forever to root and be weak.
Use a sterile medium like vermiculite or perlite, definitely not water or soil as the rooting medium. Bottom heat at 70 to 80 degrees will speed the rooting. I don't use rooting hormone any more, but fungicide might still be useful, especially if the rooting medium is cold and wet.
It usually takes 2 weeks or more for cuttings to root, and another 2-3 weeks for the plant to develop a good root system.
