I have mildew forming on squash plants and aubergines. Can I treat this or will the plants continue to grow despite the mildew. Thank you.
It depends how you are looking after them. Mildew is a response to conditions that favour leaf decay. If its on all the leaves, clearly your plants are dying! However I suspect its on a few lower, older leaves which is closer to normal.
Definitely not worth treating, just check you are giving plants what they need to grow healthily. Aubergines in particular need warmth.
Also some courgette leaves have grey colouring which can be mistaken for mildew.Last year the leaves of my gigantic courgette were covered in what I assumed was powdery mildew. It thrived, and only slowed down producing as the temperature dropped, but still produced up to the frosts. This year my courgette plants look rather pathetic.
My Squash leaves have gone quite silver this year – I think due to the low temperatures as all new leaves are looking good now it is warming up a bit more.
