My Tomatoes' Journey: Eggshells (Part 6)

While learning about growing tomatoes, I ran across the suggestion of using eggshells to prevent blossom end rot. Last year, my tomatoes got hit hard with this, and I'd like to avoid it if at all possible. 

Blossom End Rot
Blossom end rot generally happens because of too much moisture, which is what happened last year with all the rain. (Apparently this can happen with really dry conditions as well. These tomatoes sure are finicky!) Monitoring moisture levels and introducing enough calcium to the soil will help prevent blossom end rot. Low and behold, eggshells provide a rich source of calcium! So, I will be adding eggshells to my soil this year when planting.

Simply save your eggshells, and let them dry for about a day. I like to rinse mine out before setting them back into the egg carton. 

To crush the eggshells, put 12 shells in a plastic bag and smash them with a rolling pin. I store the shell crumbs in increments of 12 eggshells, because each plant will need about a dozen shells. Then, store in a plastic baggie or container until ready to use. 

Use the eggshell crumbs in a month or so after you plant your tomato plants outdoors. Add approximately 12 crushed eggshells to each hole before planting your tomato plant. This seems like a lot to me, so I'll see how I feel when I actually plant the tomatoes outside. 

So, start saving your eggshells!

  1. That is probably the coolest rolling pin I have ever seen! I want one! The eggshells trick is new to me, but it makes sense since you put eggshells into compost. They must be good for something! I wish I had known that when I had all those chickens. I'll keep it in mind for the next time we raise birds. You know, when we are home for more than an hour a day thanks to all those extracurricular activities. I can't wait until we can plant things! At this rate we'll be lucky if the ground is thawed by memorial weekend.

    1. Isn't it cool? My mom got it for me for Christmas. I think she bought it while she was on a trip somewhere. I hope the snow thaws sometime before June for you all up north!
