when are you sowing your garden this year?

Well since it is garden related, I show what I did from spring to fall.
New to me backyard had a three tier gravel pit weedfest with dead trees and other crap. I pulled landscaping blocks out and moved the rock from the middle to front (had to get a few more to finish it). I pushed all the rock into the front lower section so I expect some settling over the winter.
Top tier is still there but much smaller and will be lined with railroad ties.
The left side I plan to have two 12x4 garden beds and a smaller maybe 2x4 (herbs) bed. Right side (north/shaded) will have flowers and birdbaths stuff like that.
I still need the railroad ties for the garden sections (as well as quality dirt). The old area did have a sprinkler/drip line running around all the dead trees. I'm removing that valve from the sprinkler box by the house and running a direct line to the upper left. I plan on dropping in a new value box that can accommodate 6 valves (but I plan for only four for now). The sprinkler lines will run behind the railroad ties lining the back tier then pop out for each garden bed (different zone for each bed) and have drip lines. The rest will be covered with landscaping paper and gorilla hair with walking pavers eventually.
Any set up advise is appreciated.
