I discovered my green thumb in the garden last summer, so this season I’m expanding my plant kingdom. On the hunt to find a last freeze date, I naturally found The Old Farmer’s Almanac website and promptly signed up for its Companion Newsletter. It now arrives daily in my inbox, with sunny bits of advice about growing vegetables and herbs, interesting stuff happening in the night skies, weather tidbits and advice for a life well-lived in the outdoors; almanac.com.
