If you can till it up really well, do that, then plant the strawberries. If you rake it after tilling, a lot of the weeds will get pulled off, the rest you will just need to pull as they come back, but with the ground tilled and the weeds not well rooted, they will pull very easily. Dandelions are the very favorite for all my poultry, from chickens to peas.
Planting peppers and tomatoes now is pretty safe. The critical thing for crops is the night temps, now that they are mostly above 50, the plants will really start to grow fast.
Chickens like dandelions? I have a farm growing in my front yard! Will have to try that later today...
