The next time you have green onions, don't throw away the white ends. Simply submerge them in a glass of water and place them in a sunny window. Your onions will begin to grow almost immediately and can be harvested almost indefinitely. We just use kitchen scissors to cut what we need for meals. I periodically empty out the water, rinse the roots off and give them fresh water.
TIP FOR KEEPING BERRIES FROM GOING MOLDY ~ Dump berries into a mixture of one part apple cider vinegar to ten parts water. Swirl around, drain, rinse if you want and pop in the fridge. The vinegar kills mold spores and other bacteria on the surface of the fruit. Raspberries and strawberries will last longer in the fridge without getting moldy and soft.
