Re: aphid infestation

Anna,

The emergence of aphids from wherever they hide is one of the sure signs of spring for me, on seedlings and new growth on my greenhouse plants. I squish them carefully, though sometimes I wonder whether my fingers actually do more damage than the the aphids were doing.

I don't notice many aphids in the summer, though today I noticed some on a rosebud as I was watering, so I sprayed them off with the hose.

Could you spray your infested trees with plain water?

I just did a Google search for birds that eat aphids, and several people reported goldfinches cleaning all the aphids off their roses.
