^ that's a (fine) solution for potted balcony plants.
I used to pick them off by hand & power wash them off every afternoon with the hose,
but I almost fell of the ladder when trying that with the taller apple trees.
Sometimes it would work in the garden if I designated a few 'sacrifice to the aphids, plants.'
Hand pick & hose off the majority & then sit back & watch the ants 'herd & farm' the aphids. Fascinating.
