Could someone tell me why my Violas have got this white mildew all over the leaves , they are in my greenhouse at the moment is this too warm for them ?




I would suspect that is the reason and perhaps too humid as well. Could they go outside after hardening off? I think they would do better outdoors.

Powdery mildew can be down to exposure to humidity and poor air circulation.

They should improve now.

Um, I'd spray them, frankly, with a fungicide suitable for mildew. Mine have mildew currently and they are outside... you could also try the 1 part full fat milk to 9 parts water trick and spray with that, but I'd use a fungicide.
