First, plant some flowers. Watch them grow. Nice, eh! Bees will burrow into the soil and lay their eggs. Nicer yet! Voles will come and root around, as voles will do. By this point, a few years have passed, you’ve done nothing except plant flowers and peer into bee tunnels to see what you can see (darkness). The soil is hollowed out now, and then the deer come and trample all over it with their sharp little feet, and it all collapses like crazy, it’s all manured, and it’s all growing, in early January yet.
And you’re done! Now, how hard was that? Bees and deer: partners for life!
