Most people think plants love expensive fertilizer that you buy in bags, spays and time-released pellets, but there may be something else that's more eco friendly, much cheaper and you may already have it in you house.

The chemical formula is MgSO4-7H2O and chances are, you've used it for your own body.  It's hydrated magnesium and we all know it as Epsom salt.  Discovered for the first time in the town of Epsom in England, this product has had medicinal properties and seems to be a beneficial for agriculture.

Epsom salt is said to be especially good for tomato and pepper plants and roses.  Many organic farms have started using Epsom salt instead of mainstream fertilizers.  And even though there is not a lot of research out there to prove that it works, people who use it, swear by it.  Epsom salt contains magnesium and sulfur that most plants need to grow.

You can add it directly to the soil or dissolve it in water.  A tablespoon of Epsom salt per foot of plant height sprinkled on the top of the soil of house plants seems to do the trick.  Do that right before watering.  When mixed with water, use approximately two teaspoons per gallon of water twice a month.  Your plants will love you and you can soak yourself with what's left.
