“In fact, the taproots are edible, and smell like bananas. Just try not to touch the leaves or stems!”
I’ll be telling Beau - as you know, he’ll eat anything that doesn’t eat him first! ;)
I’d suggest marking out an area with lots of first-year plants, then digging in the fall after a good hard freeze and thaw. Scratch and sniff each root as you dig them up, sometimes other plants like to hide amongst the parsnips that have the same shape and color of taproot. There’s no mistaking that banana smell, though.
And wear gloves, just in case some of the leaves are still kicking!
