Is it a sign of my age that I set such store by all the old sayings? Nope ... I learned most of these bits of folk lore at my mother's knee, and they have stood me in good stead over the years wherever I have lived.
So, I always wait to start my greenhouse up until the geese are back .... I never direct seed in the garden until the leaves are on the trees and if the Full Moon is early in the month of May, I wait until the end of the month to transplant my seedlings. ( this year I'll transplant in early may .... likely on the 7th or 8th... because the fourth quarter is a great time to transplant and the Moon is in
Pisces. )
Last summer I built a play yard out front for my dogs. There is so much wildlife around here that is the only reliable way to keep them safe off leash. Now I dearly love my dogs, but some of the herbs in the pond garden out front will have to migrate out back to the new gardens that I'm building out back. The Lady's Mantle, the Comfrey and the lavendar simply wouldn't stand up to the exuberant wrestlemania and games of hide and seek: ))) 
Last year I refurbished the little garden shed .... having finally decided to keep it in place if for no other reason than to serve as a privacy screen for this little back garden. By the time the 34 fence post holes were dug ... in land that is, as the locals say , 'a little ledgey", summer was nearly done and it was almost hunting season before the play yard was finished
If, like me, you are planning on building a pond this year ... be on the watch for underlay that gets put out for spring pickup. Just because you wouldn't use in your house doesn't mean that it won't make great underlay for your pond to protect the liner. If you know anyone who has dismantled an above ground pool, the pool liner makes a dandy pond liner too.
If you live in the Greenwood area, the crushed brick for the path around the round patio came, very reasonably, from Happy Joes.
PS ... don't toss out cracked and broken clay pots as they can add interest (and refuges for toads) in perennial gardens
