To test the ground broken into a fine tilth by my recently purchased Mantis, I have directly sown a few of the following to test direct sowing instead of sowing in pots all the time:
Early Nante carrots
Crimson Forrest red spring onions
Scarlet Globe radish
Paris Silverskin onion
In pots: Parsley, Thyne, Basil
I have also sown 8 varieties of flowers and transplanted Arcadia and Parthenon broccoli to their final position.
