Good morning everyone, I'm about to plant out black kale and would like to know if the standard curtain lace (plain, no pattern) will keep out the whitefly?
Are whitefly bigger or smaller than thge holes in curtain lace?

Cheers,  Tony.

I've got some black kale to pot-up and plant out later but hadn't thought about any whitefly invasion. Maybe soapy water would help to wash them off, or as my OH does, pick the leaves and wash them so they drown!

They get through scaffolding netting!

Does anyone know the date/time of the imminent invasion? ?

Cheers,   Tony.  (Just playing with settings)!

Flea beetle have got through enviromesh !!

My experience of netting with enviromesh, green debris netting or fleece is that they still find a way in.
While we're on the subject, does anyone have experience using SB Plant Invigorator against brassica whitefly?
