I first encountered lupin aphid years ago and take the precaution now of,spraying just before flower spikes form. Seems to work very well. Lupins are definitely worth growing.....such a unique flower. This year a couple of mine are,now flowering for the THIRD time.
Matt, if your lupins are outside now and are of reasonable size they prob,will survive outside later. It's just that,I,don't like to lose any plant if I can help it so I anticipate what may or may not thrive
