How To Correct Calcium Problems In My Garden?

Question

The bottom of my tomatoes rot when they start to turn red. I have read this may be a calcium issue? We water with town water so I am worried there is too much calcium. How can I correct this?

Answer 1

Usually, this is a lack of calcium, or an incorrect calcium to magnesium ratio. It can also be due to pH imbalances, so make sure to test your soil. Ultimately, you will find that you may need to spray with a calcium foliar spray, such as Epsom salts.

I recommend keeping dolomitic lime around, and adding it on occasion. It will stay around for awhile, in the soil, and keep the pH balanced while adding calcium and magnesium to the soil.
