Last summer, a dahlia I planted where a big bush had been taken out grew into an absolutely enormous plant with big fluffy flowers strong enough to house a snail.
Poked around at the remains a bit ago and found apparently healthy tubers down there. I’d been resigned to mush.
There are sprouts! I’m not holding my breath, but there are sprouts! Considering pruning the old bits closer to the ground in order to put a cover on the new ones.
