Grow English Marigold beneath the Sprouts. They don't like the smell!

Thanks for that but the sprouts are in the garden now and covered in the darn things.

washing up water

Or spray with soapy water using washing up liquid diluted in a spray bottle.

Yes from me too soapy water works.

I have some white fly on my sprouts, don't spray if you are picking them. The soapy water won't hurt unless it's carbolic. Pick your sprouts and soak in vinegar and water overnight, the flies will float to the top.

Never heard of that one before DrB - I'll remember that, or try to!

Yes, it always works MG, I remember seeing my mother doing this many moons (sorry about the pun), ago. The little devils float around on the top making it easy for preparation. Vinegar is the cure all for almost everything.

yes my mother used to soak the joint in vinegar and water in the days of meat safes, hear we go I forgot to put that on the clock sarger
