How to grow salvia divinorum

 Diviners sage grows wild in the cloud forest of Sierra Mazateca which is both humid and cool. Temperatures are on average in the 60s(F) and the humidity hovers in the 60% range. When cultivating any plant it's best to mimic its natural environment the best you can. Although, this is not always practical....or convenient. 



Salvia divinorum plants love humidity! Staying at or above 60% 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 in my opinion is its low maintenance! The chamber is simply a clear storage bin completely covered with 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. Another good option for maintaining high humidity would be placing the plants in an open tote and allowing an ultrasonic fogger/humidifier on a timer to fill the tote periodically. 

      For those who want to skip the hassle of regulating humidity salvia divinorum can be acclimated to lower humidity by slowly introducing it to the open air. Old leaves will distort and become unhealthy, but new growth should be fairly healthy as long as the plant is in good condition. The Bounty botanicals grow room is around 30% humidity to give you an idea of what salvia can adapt to. Growing salvia in low humidity make our plants able to withstand more stress making the transition from our garden to yours that much easier!   


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) seem to be ideal. 


 Intense sunlight or HID lighting may prove too much for your salvia to handle. Salvia grows on the forest floor and is shaded by the tree canopy. If growing indoors then fluorescent lighting works great.


 Choose a soil that is slightly acidic(most potting soils are) , high in composted matter, and well draining. A good potting soil with some added perlite works well. I like to use Ocean Forest mixed with Happy Frog(not a sponsor) at about a 50/50 ratio and add a bit of extra perlite to thi mix.   


Salvia doesn't like for its soil to become too dry, but you shouldn't drown it with water either.

Here are a few general watering tips:

         - When watering, water thoroughly and infrequently as opposed to a little bit all the time. 

         - Give the soil time to deplete at least some of its water before watering again. This gives the soil time to breath, which is very important to both root growth and over all plant health as well as the soils microbiome.

         - How dry you allow the soil to get to before re-watering is dependent on the type of plant you're growing. In this case, salvia doesn't like for its soil to get very dry. 

         - Learn what your plants watering needs are by "listening to your plants". To do this, wait until your plant just barely starts wilting before watering again. Note the dryness of the soil and the weight of the pot if possible. By doing this you'll know what the plants limits are as far as drought tolerance goes .  !!Only do this process after your plant has been acclimated to its new environment!!

         - Do not rely on time to tell you when to water. Many factors such as growth rate, temps and humidity, among other factors directly correlate to how much and how often your plant will need to be watered. Since these conditions are constantly changing, so will the watering needs of your plants. 


 Use a mild vegging fertilizer at regular intervals following the labels instructions. Don't use at full strength. Start at 1/4th strength and go from there. 


That's about it folks!
