Remedy for aphids made a monkey out of me


Summertime 2012

The roses in our backyard have survived more than fifty years of north Idaho winters and bloomed for as many summers. Recently, though, I noticed that a colony of aphids had invaded the new rosebuds on two of the bushes. I dislike aphids and the damage they do, but I don’t like to use pesticides in my garden. A dishwashing -soap-and-water mixture in a spray bottle worked fairly well last summer, but I recently read about another remedy that sounded even simpler.

A Facebook friend posted enthusiastically about her banana-peel cure for aphids. Aphids hate banana peels, she wrote. As soon as she started using them on her rose bushes, the little green beasts surrendered and decamped.

My husband, Lee, eats a banana with his lunch on the weekends. So how hard could this be? Last Saturday, I fished the banana peel out of the kitchen trash bag and draped it across one of the infested rose bushes. I wasn’t sure whether to drape it with the outer peel facing the aphids, or the soft, inner peel nearest to them. Were aphids smart enough to find the right side of the banana peel if I’d guessed wrong? And hanging the peel across the tip of the rose stem, where the aphids gathered, turned out to be tricky. The peel kept dropping down onto the middle of the bush, where no rosebuds grew. Would the aphid army be willing to travel downhill to land on the banana peel?

Finally, with patience and luck, I managed to hang the peel in the best possible spot to trap those aphids. I called Lee away from the side yard, where he was building me another raised garden bed, to admire my latest example of horticultural genius. “Sweetheart, there’s a banana peel hanging from that rose bush,” he said. When I explained my strategy, he made an odd sound that might have been a cough, or a smothered snort.

The next day after church, I led him directly to the backyard to gloat over the aphid graveyard. By then, the banana peel, now brown and withered, had dropped a few feet and was dangling from a lower branch. I picked it up, using two fingertips, because I didn’t want to have to touch all those aphid corpses. But...there were no aphid corpses, on the banana peel or lying in even a small heap at the base of the rosebush. There were, however, dozens of aphids having brunch on the rose buds.

When my Facebook friend wrote about using banana peels ON her rosebushes, I took her words literally. To an impetuous gardener, draping a used banana peel on a plant sounds creative, rather than …eccentric. The banana peel fiasco made a monkey out of me. If only I had done some actual research before I started decking the rosebushes, I would have read the following:

In the roses forum of GardenWeb.com, a reader asked if banana peels will eliminate aphids. The rose expert’s response: “I think about the only way a banana peel would eliminate aphids would be if you placed the aphids on a flat surface and beat them with it.”

Reader’s Digest’s online site, in an article titled “Eight Uses for Bananas,” added further humiliating details: “Are aphids attacking your rosebushes or other plants? Bury dried or cut-up banana peels an inch or two deep around the base of the aphid-prone plants, and soon the little suckers will pack up and leave. Don’t use whole peels or the bananas themselves, though; they tend to be viewed as tasty treats by raccoons, squirrels, gophers, rabbits, and other animals, who will just dig them up.”

Bury pieces of banana peels around the base of the bush. Don’t hang them from your rosebushes. Who knew? I’m going to go find a banana tree to climb now.
