Eggs are delicious but also eggshells are very useful in gardens. Did you know that? You can use them as a fertilizer, because they are amazing to beef up soil. It doesn't matter if they are more white or yellow, you can use all of them. There are only 3 kinds of plants that you shouldn't use them with: orchids, ferns and azaleas. If you want to make use of them, you simply need to strew them or bury them. Have you ever used them?

I spun mine in a blender and added to my tomatoes. They also work as slug deterrent if small enough.

all my egg shells go in the compost heap.

Actually, that amounts to about one or more egg shells per day...

Mine all go to compost, just like Frank's.

I used to throw a whole egg in the tomato hole. The proteins and carbs and other mineral are good as well. Now it is just composted manure and fertilizers.

You need to add a whole lot of eggshells to the compost heap to keep blossom end rot at bay, whereas slacked lime is about 20c/lb and one application lasts the whole season.

Wouldn't slacked lime raise the ph?
