Anyone know what’s the purpose of putting Epsom Salt in the bottom of a large pot for a citrus (Calamansi) plant?
(I saw that in a couple You Tube vids about potting citrus plants.)
Epsom Salts provide additional Magnesium that citrus plants need. It boosts fruit production, so that makes sense in a potted citrus plant.
You can use it in your garden in many ways, but correct DOSAGE per whatever you’re planting is the key:
