Q: Should we put lime in the bottom of the hole when planting our tomato plants? How much?
A: Garden lime supplies calcium that prevents blossom end rot in tomatoes. It also counteracts soil acidity. However, you don’t need much lime to accomplish either of these tasks, perhaps a tablespoonful per hole. Too much lime can be harmful. An alternative is to supply calcium with gypsum. I advise powdering a two inch by two inch piece of gypsum wallboard (Sheetrock, etc) and mixing with the soil to prevent blossom end rot on tomatoes, squash, peppers and melons.
