Q.What’s The Best Way To Treat For Aphids On My Elephant’s Ear Plant (at Least I Think They Are Aphids).
They seem to be particularly fond of congregating in the “folds” where the stem of the leaf meets the “trunk,” but also at the base of the plant, and even on the leaves themselves sometimes. For now, I went ahead and “sprayed” many of them off using the “stream“ feature of my water spray bottle.
