Epsom salt – also known as magnesium sulfate – helps seeds germinate, makes plants grow bushier, produces more flowers, and deters pests, such as slugs and voles. It also provides vital nutrients to supplement your regular fertilizer.
Plants will have visible signs that they are starved for a particular nutrient. If a plant’s leaves turn yellow all over the plant, it can be a sign they need more sulfate. If lower leaves turn yellow between the veins (and the veins stay green), they may need more magnesium.
