To the absolute despair of my hubby, I find it hard to simply throw things into regular trash (hence the upcycling projects). It makes me feel guilty thinking how long things take to disappear into nothingness. Which is why he bought me my first worm farm (which I LOVE) those little guys are fantastic for turning anything from veggie peels to dog poo into good rich soil for the garden. Best thing is that rubbish goes in... and it disappears just like magic. But even my little guys struggle with egg shells. But they are still organic and are great to use in the garden.
Plant Nursery:
You can even mark on the eggs when they were planted and what seeds are in them. And forget about having to squeeze them out of seedling planters you just crack the shell and they are in perfect pod shapes to plant in the garden.
Finally egg shells are great for spreading around the newly planted seedlings to protect them from snails and slugs. The grubs don't like the feeling of crawling over the sharp edges of the shells so they don't start nibbling on the new leaves. Above are my planted tomatoes and zucchini plants happy to be busted out of their eggshell nursery.
