Warning: I keep seeing people plant their tomatoes way too early

Every spring in my area, the big box stores put out tomato plants in April, and everyone buys them. The ground is still cold, night temps can dip below 50, and those plants just sit there, stunted and purple. I learned this the hard way three years ago when I lost six plants to a late frost after planting on May 1st. Now I wait until the soil is truly warm, at least 60 degrees, and all frost risk is gone, which for me is around Memorial Day. Planting them in cold soil shocks the roots and sets them back weeks. I use a cheap soil thermometer to check. It feels like you're getting a head start, but you're actually losing time. Has anyone else found a good local cue, like a certain tree blooming, to know when it's really safe?

My first year gardening, I was so excited I planted in early April. Those tomatoes looked so sad and purple, like tiny, leafy vampires. I basically paid for a masterclass in plant disappointment. The soil thermometer trick is a game changer, it keeps my optimism in check. My local cue is when the oak leaves are about the size of a squirrel's ear, which sounds made up but it works.

Ha, that squirrel's ear trick is pure gardening gold.
