We shut down the compost for the winter, but I continued to save eggshells. What I did was crush them into a gallon sized plastic bag in the freezer. It's about half full now.
What's the best way to use these? I plan on starting tomatoes soon, and transplanting into pots once before planting outside. Should I make a "tea" and water the seedlings? Or crush directly into the pots when I transplant?
Last year I lost the first 2 tomatoes to blossom end rot, and I panicked! Luckily that was the last of the loss, but now I am feeling a little paranoid. Are eggshells (even a quarts worth) really enough calcium to prevent this problem?
