eggshells

Are you watching the green grow on your windowsill? If so, you may want to dry out your eggshells, crush them and add them to water, then instead of plain watering of your plants, you can use this water after it has set for a couple of days. Save all the water you boil eggs in for the same purpose. When you start seedling next month, you can use the eggshells that you've soaked in water a couple of times and add them to the bottom of your pots that will contain the seeds you start.
