pinch off yellowing leaves or let them fall off ....I would skip insecticides and spray with insecticidal soap (neem oil is more for winter use - it works by smothering insects ..... spray both sides of every leaf, stem and caudex ....all the nooks and crannies ...spray to runoff
in a few hours the insecticidal soap will dry ....when *dry* the insecticidal soap is no longer effective ....rinse the powdery white soap residue off leaves to prevent possible leaf damage on hot days
most insects have *life stages*, some with 4, others with up to 6 .....these life cycles can range anywhere from a few hours to over a week ......assume all life stages are present at any one time..... repeat spray in 10 to 14 days, repeat a 3rd time....and if necessary, a 4th time to ensure the insect invasion is eradicated
