The threads a little old but I figured I'll give it a bump as my lupin spires are just forming and the aphids have made an appearance.
My technique has been cupping a hand underneath them and then gently running my other hand up the stalk and spire. Then once a load of the horrible little blighters fall into my cupped hand I give them a hearty round of applause. Squish
A crude method but the numbers have dropped significantly over the last 2-3 days with one thorough application per day of this treatment. Don't forget to wash your hands afterwards though!
I'm gonna get a little squirty bottle when I go the shops later to mix up a concoction or two to try out on the plants - So far I've read that diluted garlic powder, pepper or washing liquid can work. A season of experimentation awaits.
