Where to buy calcium spray for your garden vegetables?
Question:
Answers:
Calcium chloride is suggested only for tomatoes in order to prevent blossom end rot but calcium nitrate can be used as a spray treatment. Calcium chloride may burn the plant if sprayed during the hotter part of the day. Calcium nitrate is generally safer for the soil and other plants and may be applied in the same way at the same rate.
Spray tomato foliage only with calcium chloride at the rate of 3-4 level tablespoons of calcium chloride per gallon of water but never when plant is stressed or unwatered.

You can get great results using ebsom salts, purchased at your local drug store. I use 1/2 cup to a gallon of cool water. Then water the plants with this solution about once per week. I got this tip from an old timer that lived next door to me for years. I work hard to get tomatoes that are close to what he got. He was the best. :)
You can buy several different calcium supplement formulas for vegetables at most local garden stores but most are more expensive than necessary. The cheapest way to appraoch this problem is to buy a bag of greenhouse grade calcium nitrate and mix it at 2-3tbs/gallon of water and spray onto plants especailly helpful for peppers, tomatoes and cucubits to stop blossom end rot. The reason for buying the greenhouse grade of the calcium nitrate rather than just normal calcium nitrate is simply that it will dissolve in the water far better and want leave small particals in the bottom of sprayer that may nag you by stopping up your nozzle repeatedly.
