This Epsom salt for plants is a 3 kg pack of magnesium sulfate powder, a source of magnesium and sulfur for indoor and outdoor garden plants. Magnesium helps plants make chlorophyll, the green pigment that powers growth, and sulfur supports healthy leaf and root development. The listing says it helps improve nutrient absorption, root development and overall plant vigour. It is ideal for flowering plants, vegetables and garden greens, according to the listing. The fine powder dissolves in water, so it is easy to mix and apply for regular feeding.

Epsom salt works best when your plants actually need magnesium, so it is not a replacement for a complete fertilizer. Yellowing between the veins of older leaves, while the veins stay green, is a classic sign of magnesium shortage. Potted plants in rainy cities like Mumbai can lose magnesium when heavy rain flushes nutrients from the soil. How to use Epsom salt for plants: dissolve it in water as directed on the pack, then apply it to the soil or spray it on the leaves. Foliar sprays are best applied in the early morning or evening, not in strong sun. Do not apply it on dry soil, so water the plant first. [Dose per litre, frequency and whether to use it as a foliar spray or soil drench, from the pack.]

Gardeners often use it on tomatoes, chillies, brinjal, roses and potted palms, which tend to show magnesium shortage. Use it sparingly, because too much can build up salts in the soil and interfere with calcium uptake. If leaves do not improve, check watering, light and other nutrients before adding more. Pair it with vermicompost, a balanced NPK feed or seaweed liquid fertilizer for a complete feeding routine. Keep the pack dry and closed, and keep it away from children and pets. Ugaoo supplies this 3 kg pack. A 3 kg pack lasts a long time, because only a small amount is used at a time. Check the latest price and buy this Epsom salt for plants online in India on Amazon.
