Was out by the garden after dark last week. In the moonlight, I saw that all of my potato plants kinda lift their leaves up, at about a 75 degree angle, and slightly fold/close them after sunset. I’ve checked after dark a few other times and they seem to do this regardless of temperature or humidity.
I assume it’s normal, and it’s actually pretty neat. Has anyone ever noticed this?
Yes!!! I’ve heard of plants pulling nutrients into their roots at night to protect from predation and I wonder if these are trying to protect their buds. I never noticed it until tonight and I’ve been growing potatoes for over a decade, am I that oblivious? or is there something that triggered it? I live in New Mexico and we are two days into our first heat wave of the year (just broke 100 F the last two days).
