Magnesium sulphate, commonly known as Epsom Salt, is useful in many ways in gardening. It is full of the right nutrients to enrich regular fertilisers and turns your garden into a lush haven in an inexpensive way. Among its essential benefits are improved seed germination, amazing blooms, helping plants grow abundantly, deterring pests, and increasing chlorophyll production.
Epsom Salt Benefits in Gardening
- Epsom Salt will not get accumulated in the soil, which means your plants will be unharmed, and it is effective and safe to use during any stage of a plant's life-cycle.
- This salt can revitalise your garden, give it a refreshed look, or even help your new garden to grow faster.
- Its vital nutrients, when added to your regular fertiliser, work wonders on plants by making them lush and helping seeds to germinate
- It helps improve flower production and deters pests like voles and slugs from ruining your plants.
- You can use Epsom Salt as a saline solution with a sprayer. Add a tablespoon of salt to 4 litres of water while filling your sprayer; spray your garden with it after planting, again after a gap of a month, and when vegetables begin maturing. Avid gardeners find this practice useful to develop a lush and healthy garden.
Note: You can use Epsom Salt with any plant but avoid its use for sage varieties. Your local gardener is the best source to learn more about best practices.
Signs That Your Plants Need a Dose of Epsom Salt
You may have observed that sometimes all the leaves of a plant turn yellow, while at others only the lower leaves become yellow with their veins remaining green. In the former situation, the plant needs more sulphate, and in the latter, it needs more magnesium.
Soil naturally contains both sulphate and magnesium, but these nutrients can become depleted due to various reasons. While commercial fertilisers are retained in the soil, Epsom Salt is not, and therefore you cannot overuse Epsom Salt on your garden. It is recommended to use a mix of water and Epsom Salt to spray plants every fortnight.
