Blossom-end Rot Tomatoes

[Woody]

I just went out to pick on my Big Beefsteak tomatoes that was ripe and it has blossom-end rot. It was black, mushy and rotten at the bottom. I pulled two more large greens off the same plant that had black circles on the bottom.

I read that it's from a lack of Calcium and most pages I read only talk about how to prevent it from the beginning.

Does anybody have a solution that I can spray or do now to stop it from spreading?

Following this thread. I'm having the same problem with my tomatoes. I've never had an issue and its happening even before they turn the slightest bit red.

I just found this video. My wife picked up some Miracle Grow shake and feed that contains calcium so I am going to give that a try. It was recommended on a page I read. Read through the comments there are some interesting things like adding crushed egg shells to the soil and even tums to get calcium into the soil.

Was told years ago told that miracle grow is the quickest way to correct a calcium deficiency, otherwise add calcium to the soil in the fall for next year.
Not lack of water is it?

My dad has had the same issue over the last 20 + years. He has discovered if he rotates the tomato crop from one area of the garden to another that seems to help. He also swears by this:

I've had some issues with blossum rot too. I've used bone meal during the season with some success. A friend of mine was here last weekend and she told me to try epsom salts. I hit all the plants with it, plus some bone meal today.

The heat and uneven watering can have a huge impact on Blossom end rots. I've not had an issue this year but I use nitrogen fertilizer sparingly in my garden (many are using too much N fert -- manures etc). I am going to have to add more mulch this fall though as I can see organic matter is declining in areas.

I read that it was from inconsistent watering after having it my first garden year. I started watering every other day for one hour consistently and haven't had it since. Didn't change anything else. I do rotate my crops.

This is very educational. I don't have it with mine but I've planted 25 of the dang things and five are producing heavily so good to know what to do if it happens. I do put my birds' crushed eggshells back into the soil just for recycling purposes but that may be what's preventing it.
