How much Epson salt should you use per gallon of water for leaf curl on tomato plants. Also how should you apply it to tomatoes and peppers?

Team Gardenoid

Hey Robbie,

Here are the answers to your queries:

1. Mix 2 tbs of Epsom salt in a gallon of water and apply directly to the leaves.

2. While planting a new tomato plant, dig a hole and put 1 tbs of Epsom salt at the bottom of the hole and cover it with the thin layer of dirt and then plant the tomato seeds in the hole. You can also use Epsom salt in liquid form. For this, mix 1 tbs of Epsom salt in a gallon of water and use this liquid for watering the plants.

Same thing you can do for peppers.
