Salvia divinorum growing tips: Diviners sage is native to the cloud forst of Sierra Mazateca which is humid and cool
1. KEEP HUMIDITY HIGH- Salvia loves humidity! Staying at or above 80% is ideal and can be accomplished in lower humidity environments with a greenhouse(outdoors) or a growth chamber called a "shotgun terrarium" for indoor plants. A shotgun terrarium is typically used by mushroom cultivators for its humidity holding capabilities as well as allowing fresh air to circulate; but the best thing imo is its low maintenance! The chamber is simply a clear storage bin completely covered in small holes(get it? shotgun) and filled several inches with wet perlite. Tutorials for making a shotgun terrarium can be found with a quick google search. salvia can be grown in lowers humidites, but leaves tend to brown at the tips. If you prefer to go the less humid route the plant will need to be slowly adapted over a few weeks.
2. KEEP TEMPS COOL- Picture a cloud forest....clouds(fog) all the time. If you've ever been in fog you know it tends to be cool. Temps in the 60s-70s f. are ideal. Higher temps are ok but be sure to keep it well watered!
3.KEEP IN FULL SHADE- Salvia grows on the forest floor and is shaded by the canopy. If growing indoors fluorescent lighting does great!
4. GROW IN GOOD SOIL- choose a soil that is slightly acidic(most potting soils are) , high in composted matter, and well draining. I prefer a good potting soil with some added perlite.
5. KEEP SOIL MOIST- water once the soil STARTS to dry out. Never let the soil dry out completely.
6. FERTILIZE REGULARLY- use a mild vegging fertilizer at regular intervals following the labels instructions. Dont use at full strength. Start at 1/4th strength and go from there.
