Anyone have any idea what causes rhubarb to be excessively sour?

Thanks!


Oxalic acid would make it sour.
The plant needs frost.
Weather and moisture have a great effect on the plants tenderness,
"sweetness", edibility, etc. Hot, dry temps and you can just about forget
it. However, when the temps are agreeable and the rain plentiful, it is
possible to harvest rhubarb long into summer months. I recall once
harvesting it in southern Wisconsin well into July and early August.

Rhubarb pie is a sure sign that spring has arrived.
