Help, all my zucchini are bitter! About the plant: -Grown from store-bought seeds (not a single one was bitter last season), -No ornamental squash nearby, -Watered regularly, -Grown in partial shade None of the reasons (according to Google) apply—are there any other reasons why they might taste bitter? I’ve harvested 4 so far and they’re all bitter—should I throw the plant away? Best, Patricia
