While ground condition are perfect now it is just a little too early to sow any of the game crops and wildflowers yet. You might get away with it but if the weather turns wet and cold in the next 2 weeks the seeds will only perish in the ground. It is very early in the year yet so I would advise waiting until the middle of April and hopefully conditions will be as good then. You should also have warmer nights from then on so the crop will grow faster with the higher temperatures by night. Even if it does go into early May before sowing you will be still in time to have a very good crop.
