Really! They just don’t know when to stop.
After pulling my potatoes for an early harvest (we have a busy September coming up) I chucked the haulms, along with my peas, into a heap on some cleared ground. I would deal with it later, honest.
Well, now is later, and moving the rubbish heap to the compost bins I found that several of the almost-intact potato plants were happily forming new, tiny spudlets.
I’ve never know that to happen – they were in the sun, drying out, and they’re producing a little harvest of new potatoes.
Now that’s productive!
