Has anyone followed this, and if so, found it to be accurate or inaccurate? I was surprised to enter my zip code and be advised to plant things often a month earlier than I have usually done. Perhaps I've just been too cautious in the past? I've never started any warm weather veggies (beans, cukes, etc) before 1st of June, but the calendar says OK to direct sow in mid-April (???) I'm willing to give it a whirl, but wondering how the planting dates might match up with your experiences.
