At times in life when you are faced with an obstacle and unsure what to do, you often hear the expression – you’ve got to crack a few eggs to make an omelette. I crack eggs not just to make an omelette, but to try and overcome a gardening obstacle – SLUGS – and also to feed the soil. Some gardeners swear by crushed eggshells as a slug deterrent, whilst others say it is a waste of time. I am off the former. Eggshells act as a natural fertilizer, conserving water and improving soil health. They contain calcium which is good for plants.
I bake in the oven on a low heat for about an hour which enhances the sharpness of the eggshells, plus this method means they last longer once scattered on the soil.
and then lightly water the soil. I keep some back to sow with the seedlings in their final planting hole. I may never deter all the slugs who love my allotment as much as I do, but I am sure I deter quite a few. Another batch from my winter collection will be scattered over the remaining bed next week.
Later in the summer I add crushed eggshells to the compost heap. I discovered a gardening tip late last year – mixing crushed egg shells with dried coffee dregs (a mix of calcium and nitrogen) is good for tomatoes. I shall give it a go this year!
