Help your plants grow with this highly recommended Epsom salt that Amazon reviewers swear by!

Here are four different ways to use Epsom salt to give your plants a boost and one way to keep pests off of your hosta plants.

1: Tomato Plant Booster

Add two Tablespoons of Epsom salt to one gallon of water


Feed your plants every two weeks with this booster for bigger tomatoes.

2: Pepper Plant Booster

Add one Tablespoon of Epsom salt to one gallon of water.

Pour into a spray bottle.

Spray directly onto the plant every two weeks and you'll yield more peppers per plant.

3: Hosta Pest Remover

Combine one cup ammonia and one cup Listerine original mouthwash.

Add one cup Epsom salt and stir until salt is dissolved.

Add one cup lemon Ajax dish soap. DO NOT STIR IN.

Pour mixture into a spray bottle.

Spray hosta, wetting the leaves.

Repeat as often as necessary.

4: Indoor Plant Booster

Add two Tablesoons of Epsom salt to one gallon water

Water your houseplants once a month.

5: Give Transplanted Plants a Boost

Fill the planter pot with potting soil halfway to the rim.

Add a pinch or two of Epsom salt.

Combine salt into the soil. You don't want the plant to directly touch the salt.

Plant the new transplant as you normally would.
