Well.....after you hardboil some egss, let the water cool and water them with it. Crush the shells and mix them into the top layer of the earth and they will release calcium each time you water.

Unfortunantly, there is no magic product on the market to deal with BER (though some claim to do so).

The only thing that effectivly combats BER is:

1. Even watering - Avoid drought/drown as this is the most common culprit

2. Don't over-fertilize - If a plant has too much foliage it will pull the calcium to benefit the plant at the cost of the fruit. A good rule of thumb for fertilizing tomatoes is a well balanced fertilizer applied just after transplant and just before fruit-set.

3. Check the pH balance - Tomatoes love a slightly acidic soil. About pH 6.3-6.8 7.0 is almost the upper range of tolerance. Above 7.2 and you will need to work in some garden sulpher to bring it back down.

4. When you are preparing your containers, be sure you work in plenty of compost (1/3 by volume).

I'm not sure how prone to BER Early Girl is specificly, though you are correct that some varieties are particularly prone to BER, with the Paste varieties being especially notorious. Sometimes you can do everything just perfect and still get BER.

Plants that are under stress will also develop BER but will usually fix it's-self as the plant grows up and becomes better able to handle the stress.

The best possible advise I could give you is to pop over to the Growing Tomatoes Forum and ask Carolyn. She's a microbioligist and true-blue tomato expert, and is the one who's taught me everything I know about BER :D

I am having the same problem with my container tomatoes. Carolyn suggested crushed egg shell tea. I am assuming that you steep the crushed shells in very hot water, cool, and water with it. Don; does the prior cooking make a difference?
Thanks

I don't think steeping the eggshells is going to make much difference since calcium carbonate has a very low solubility in pure water. Once in soil however, the eggshells should begin to dissolve.
I assume your toms are in full sun? Shade and excessive humidity can also induce calcium deficiency.
