I would say you’ll be fine if you can get hold of plenty of compost soon and perhaps cardboard if your garden is weedy. I’m building my beds at the moment (as fast as I can shovel manure). I’m aiming to get as many done as possible so when I’m ready to plant/sow I can get going.I’d say go for it!
Started my current plot later than this in 2016, it was like this:see picture 1
Covered cardboard and composted with well rotted FYM. Planted out established plants and enjoyed good crops right from the first harvest
