When my children were younger we always celebrated the coming of spring by growing real grass inside assorted baskets recycled from thrift shops. Once the grass came up they each decorated their baskets with little colored bees and butterflies on wires and tucked paper bunnies into the grass.
The baskets stayed in the windowsills for a few weeks. I added goodies into them every now and then, such as little insect chocolates, small books, pack of cards, bubbles, little toys, felt chicks, etc.
Materials needed: baskets or another kind of container, tray etc, ¼ cup of wheat berries per average size basket (wheat berries can be found at any health food store, usually in the bulk foods section). potting soil, a plastic bag. Many baskets come with a plastic liner already inside. A spray bottle works best for watering.
Keep the basket covered with newspaper until the seeds begin to sprout. Then take off the newspaper and move the basket to a sunny windowsill and watch the grass grow. Water it everyday with the spray bottle. You’ll have an inch or so in a few days and then it takes off. Soon you will have a lush little field of tall, and edible, grass.
Decorate! You can download and print these directions and drawings for bunnies, bees and butterflies. Color and cut them out. Attach thin wire to the back of the butterflies and bees and tie onto the basket. Tuck bunnies into the grass.
