I harvested sweet peas in Feb and March. They went into the ground in January. I live S of Tylertown.

When I read 'sweet peas' I think of flowers. When I read 'harvest' I think of things you eat. Whichever you meant, I think the procedure is similar--you plant in winter and pick in late winter. I haven't done it, but I have gardening friends who have done both, so I know it's possible. Think it's wise to use an inoculant. You could check with the LSU extension office or web-site.
