If you are seeing white powder-like substances on your Flapjack (Kalanchoe) plant then you are not alone. We all noticed this. Yes, it is normal to have those white powder-like waxy substances on Flapjack Succulent plants. In this article, I’ll cover the natural white powder found on flapjack succulents, followed by a discussion on the possibility of mildew.
Is it natural to have white powder on Flapjack succulents?
Yes, you can find natural white powder on Flapjack succulents and those are normal. The wax-like substance is known as epicuticular wax. I have heard people calling it Farina as well.
Tip: If you are planning to wash it off, stop thinking about it.
The white coating is absolutely natural and beneficial to Flapjack. If you try to wash it off, it will be difficult for you as the white thing is more like wax.
Benefits of the white substance
That white thing helps our flapjack succulent to prevent water loss in arid conditions. The white powdery coating acts as a sunscreen for the plant. I am telling you this because they can reflect UV rays.
If you place your plant in a brighter place, you can see that the plant will generate more white coating like that.
How to Tell If It's Not Just the Natural Wax (Epicuticular)
If you are witnessing other issues along with the white coating then you should check if that is only the natural epicuticular or if something else is also there on your plant. (For example, powdery mildew as it also causes white coating if it infects our plants)
To check if it is normal or not just try to rub the white powder with your fingers gently, if you find it difficult to rub off then you don't have to worry. Those are natural white coating.
But if you find the white substances are sticking with your fingers then you need to be alert as your flapjack is infected with pests.
Tip: Sulphur helps and can be purchased at the garden center. (If you find fungus mildew)
Note: There is a rare chance that your plant might be infected with mealybugs, but if you see any sign of mealybugs then simply dip a tissue paper in alcohol and gently wipe off your Flapjack succulent with that tissue.
