Common [Non-Pest] Problems

[Paradoxic]

Here is a list of some of the common problems people have when growing Salvia D. The list also includes ways to cure them.

Yellowing Leaves
If leaves start to yellow and loose their green color your plant may be getting too much water. Over-watering will flush nutrients in the soil resulting in a nutrient deficiency. Reduce watering frequency or perhaps keep it out of the rain. To get the leaves green again get some chelated iron (liquid or powder) and use according to the directions on the product. Stern's Miracid is a good fertilizer that contains chelated iron, but really any fertilizer should work. Yellowing leaves can also be a result of too little light causing reduced production of chlorophyll. Another possibility is your plant is not getting enough water, resulting in dead chlorophyll. However, if this is the case it is likely that your plant will also be droopy and weak-looking.

Slow Growth
If the conditions for your plant seem optimal, but its growth has slowed or it appears weak you may have root-bound. This occurs when the root system is too large for its pot. You should repot into the biggest pot practical as Salvia divinorum needs a lot of root space, more than most plants.

yellowing leaves is also a common sign of too little light. because the plant isnt getting enough sun, it produces less chlorophyll wich is what makes plants green.
