My tomato plants I put in April 29th and it turned out to be the right decision. That was very early and they were barely visable in the straw mulch but my how they have grown.
Super Sugar Snap direct seeded into the ground on March 21. Growing great. I just left it to sprawl were it wants to go.
Pots of Mamoth Melting Snow Peas.
And the Sugar Lace II Snaps also in pots.
