I have a bag of old seed packets that we keep on the back porch for emergency garden planting. It happens fairly often. Zoe watches a show where somebody plants something and she immediately has to go outside and try it herself. We dumped a bunch of seeds in the dirt under a tree [lettuce, zucchini, sunflowers, radishes, marigolds...] and Zoe turned it into a mud puddle. An hour later she told me "I've been waiting a long time for those seeds to grow."
Then I saw a squirrel digging it up.
We'll see what happens.
