I have several poinsettias, one for quite a while, and has large white bumps on the stems, plus little white specs on the petal/leaves. the latter looks like aphids, which I have found on three other plants that are newer. Also have a angel wing geranium and calla lillies with the same spots. If aphids what is an enviornmentally safe way to save my plants?
