Whether you are sprouting herbs, flowers, or veggies, this easy DIY method gives your seeds a strong start.
It’s a great project to do with kids! See back for instructions.
Ingredients and Directions
Directions
Prepare eggshells: Crack open eggs around the top of the smaller end. Pour egg yolks and whites into a separate bowl, stir until mixed and freeze in smaller containers for later use.
Rinse and let dry: Once dry, poke a small hole in the bottom of the wide end with a toothpick to allow for drainage.
Fill with soil: Add soil to each eggshell, leaving space at the top.
Plant seeds: Plant seeds according to depth instructions on the packet and gently water, ensuring it’s moist but not soggy.
Create humidity: Cover with plastic wrap or a clear dome to retain moisture. (Optional)
Place in a warm spot: Put on a windowsill or in a warm, sunny spot with indirect light.
Monitor growth: Keep the soil moist and ensure the seedlings get enough light. Rotate once a day to ensure all sides receive sunlight.
Transplant: Once seedlings are strong, transplant them outdoors or to larger pots, leaving the eggshells intact to break down and fertilize the soil!
To ensure food safety, eggs should be cooked until both the yolk and the white are firm. Consuming raw or undercooked eggs may increase your risk of foodborne illness, especially for those with certain medical conditions. For recipes that call for eggs that are raw or undercooked when the dish is served, use either pasteurized shell eggs that have been treated to destroy Salmonella, or use pasteurized egg products.
