Global warming’s impact on your garden
from Slate Magazine by Constance Casey
Lilac bushes in New England have pretty steadily been blooming earlier every year for the past 30 years. One way some gardeners have begun to think about shorter winters is to say, “Hey, great, I live in Ohio [or wherever, north of the Mason-Dixon Line] and now I can grow some camellias, maybe a fig tree.” This is, frankly, nuts. Be careful what you wish for. Kudzu is creeping north, poison ivy is growing more toxic on its diet of extra carbon dioxide, and allergy season lasts longer.
