Why do most lupin leaves I have have a mould on them?

Dorset, United Kingdom

Every year my lupin leaves go mouldy...it doesn't seem to impare their flowering but doesn't look great. I've tried different places to plant them, including in pots, as I thought it might be a damp problem from overwatering but it has happened again to all of them.

Lupins are particularly vulnerable to mildew, wherever they're planted. You could spray them at the first signs of its reappearance with a fungicide, preferably a systemic one.

Hi Fluff,

Try to make sure your lupins have room enough. If you can get some air circulation around them that would help with the powdery mildew a bit. You can use a fungicide such as sulfur sprayed onto the foliage. That is what works best for me. Apply it about every 7 to 10 days.
