Uck Uck Uck, bitches
You sound like me...Ha! New Gardeners get so excited ...25 -40 years ago I set out my heirloom starts in mid May that was zone 8a...Now in 8b and for about 18 years-ish I put plants out after hardening off at the end of May or in the first couple weeks of June...There has been a climatic shift...Fall frosrt t dates have exteneded the season.Typically we don't plant outside till mid May, often later. Our hoop house tomatoes go in June 1st or so.
Over the last 3 year's, tomatoes planted early, whether in hoop house or outside have underperformed or barely equaled those planted early. The cool nights seem to put the plants into a stupor, and takes them a while to recover.
These are all heirlooms, so some of the more modern varieties such as those out of OSU may tolerate cold better.
