vegetable plutonium

In my more active anti-nuke activist days one of the more com­pelling argu­ments against nuclear power was that some of its byprod­ucts were so long-lived that they would remain lethal for longer than human civ­i­liza­tion has existed. Plutonium-239, for exam­ple, has a half-life of some­thing like 24,000 years, and even a tiny par­ti­cle of it could prove dan­ger­ous to a person.

I was think­ing about that dur­ing my weed­ing exer­cise this week­end, deal­ing with a neglected cor­ner of the gar­den where the neighbor’s Eng­lish ivy had crossed over and under the fence and set up a stand that had spread 20 feet or more into my yard. In the course of its inva­sion, it had con­tributed to a low brick retain­ing wall being pushed over.

I hate to use stuff like Roundup in the yard, but I tried it on the ivy a cou­ple weeks ago. Some of the weeds around it shriv­eled to brown ghosts of them­selves, but at best the ivy showed a lit­tle burn­ing around the edges of the leaves. I’d tried Roundup­ping the ivy before, with sim­i­lar min­i­mal results. Ivy really seems like the thing that wouldn’t die. Some online sites have guide­lines on how to get rid of the stuff, but none of them seem to guar­an­tee easy con­trol. (A cou­ple of the sites I looked at: South­east Exotic Pest Plant Coun­cil Inva­sive Plant Man­ual and the Plant Con­ser­va­tion Alliance’s “Least wanted” pages.)

I wasn’t look­ing for­ward to the alter­na­tive of dig­ging it out by hand, but dig­ging it out by hand was the chore that ate my week­end. And it’s a chore that’ll be occu­py­ing at least a cou­ple more. The job is extra-awful in that even a lit­tle piece of ivy run­ner left in the ground could grow roots and set up a whole new colony. You have to be sure to dig down the foot or so that the run­ners can travel at, and you need to be sure that you’ve rid the patch of all the alien ivy life forms before you move on to the next spade­full. It’s like veg­etable plu­to­nium in that any lit­tle bit left in the ground could prove dan­ger­ous for future gen­er­a­tions. Nasty, evil stuff.

If my mantra of my teen years was “No nukes!” the mantra of my cur­rent gar­den­ing life has to be “No Ivy!” Frank Lloyd Wright was famous for his quote that went some­thing like, “Doctor’s can always bury their mis­takes. Archi­tects can only plant ivy.” Well, friends, doing that would be the great­est mis­take of all.
