Growing Romaine lettuce from the leftover stumps. Why have I never thought of this? I know you can do this with green onions and avocado pits. To think of all the romaine lettuce stumps I've just tossed away!
Plants have best friends just like people do. Marigolds help tomatoes and roses grow better. Nasturtiums keep bugs away from squash and broccoli. Petunias protect beans from beetles and oregano chases.
