I'm 74 yrs old and have grown a garden every year since I was 14. I always put 1 tsp of Epsom Salt in the bottom of a deep hole, mix it into the surrounding soil, cover it with 1" of soil, sprinkle a handful of crushed egg shells inside the hole, then plant a tomato plant as deep as it will go in the hole. I then sprinkle a lot of crushed egg shells on top of the ground around the plant - this keeps all the cutworms/grubworms away from the stem on the plant as they will not crawl over the sharp egg shells. The Epsom Salt gives each plant the amount of Magnesium it needs and the eggshells give it all the calcium it needs throughout the growing season. I have never had any problem with any diseases and since I plant Marigolds among the tomato plants, I have never had any insect/bug problem either.
