Well, Back to DDT...

Maria Cone reports in the Los Angeles Times: "Alarmed that popular insecticides that end up in urban streams are killing tiny aquatic creatures, California's pesticide agency is conducting a review that is likely to lead to restrictions on many products used on lawns and gardens.

"The chemicals, pyrethroids, are man-made versions of natural compounds in chrysanthemum flowers. ...last fall, a UC Berkeley scientist reported that pyrethroids are polluting streams in Northern California suburbs, wiping out crustaceans and insects vital to ecosystems. "

Too much of a good thing, indeed. Pyrethroids have been popular because they are derived from natural sources: "safe enough to eat!" I remember some pitchman or other saying, as he chomped into a just-sprayed apple.

(Never mind that the pitchman now resides in an asylum, under observation for paranoid homicidal episodes brought on by neurological dysfunction. Sheer coincidence.)

Seriously, it's a tricky proposition. We value the beauty and diversity of nonnative species, but we upset the natural ecological balance when we import them. So as these plants prove a little too attractive to whiteflies, thrips , mealybugs and the lot, we turn to chemicals -- hopefully "benign" ones -- to control the bad guys, not considering that everything in nature has some connection to everything else. (Natural or not, chrysanthemum toxins were never intended to enter waterways en masse.)

To further complicate matters, pyrethroids have also been a useful weapon in a more noble fight, the protection of European honeybee colonies from the predatory varroa mites that are decimating populations of these pollinators. (Plus -- how 'bout a big shout-out to evolution?! -- the mites are developing resistance to the pyrethroids.)

In this case, the state expects to regulate or even abolish the use of pyrethroids. But our addiction to nonnative species isn't going to end -- municipalities aren't going to rip out their stands of Loropetalum and Magnolia to replace them with native plant communities. And you can be sure that the companies that make pyrethroid pesticides aren't going to roll over quietly; as the Times reported, "a spokesman for CropLife America, representing pesticide manufacturers, said Thursday that the companies were unaware of California's intentions but will cooperate with its requests. He said the industry does not agree that there are toxicity problems … 'The valuable contributions that pyrethroids make through agricultural and urban uses are many and these benefits need to be considered'."

My guess is, the chemists will develop so-called "solutions," either cultivars or pesticides, engineered to be as "safe" as everyone's new favorite artificial sweetener. Of course these will open an entirely new can of worms -- assuming the worms haven't already been killed off by pesticides, herbicides, and fertilizers -- and we'll be riding this merry-go-round again all too soon.

Ha! Told You So.

Just in time to prove my point about landscaping adding value to a home, Kiplinger's Personal Finance writes that "creating an outdoor retreat can be a worthwhile but costly venture. So make sure your money is well spent on features that add the most value to your property." Top items on the list include a covered patio and an outdoor kitchen; but luxury additions such as an outdoor fireplace, television, and grand water feature may not yield you a return on your investment.

Dressing To The Nines

As I wrote last time, a minimal investment in landscape staging can easily be assured of a 100% return, so there's no reason not to get a little dressed up when you're joining the home-sale dance.

But if you really want to see some results, consider dressing to the nines.

In 2003, Smart Money magazine reported that an investment of 5% of your home's value could return as much as 15%. So let's revisit our old listing : instead of 1%, you decide to bite the bullet and invest a whopping 5% of that $800,000 value -- or $40,000 -- into upgrading your landscape. Now we're talking about more than just a bit of greenery: this kind of money will buy you an arbor, new pathways, a deck, an outdoor kitchen, and/or a water feature... significant upgrades that really stick in the memories of potential buyers, and help them imagine themselves relaxing under the arbor or flipping steaks on the grill. If someone wants to pay a 7.5% premium -- certainly not unheard of in this market -- to call this oasis their own, you've just netted $20,000.

Where to start? Consult a professional landscape designer, who will be able to evaluate your yard's potential and offer suggestions on improving the landscaping as well as overall curb appeal. Whatever rule of thumb you follow, you can be sure that any well-executed landscape design will more than pay for itself.
