The USDA has released new climate zone maps which on the whole show a warming trend. The Northeast is half a zone warmer than the previous map, released in 1990, indicated. Henbogle has moved from 5a to 5b according to the new map.
While my oil bill might be smaller for this news, this really only has an impact for gardeners when considering plants that overwinter. The increased temperature may mean a marginally hardy shrub or tree has a better chance of survival. It doesn’t really mean the season will be longer, the frost later in the fall or earlier in the spring. It might mean though that overwintered leeks are more successful. It might also mean that some pests, reliably killed by cold winter temperatures, survive. You takes the good with the bad.
Thanks Manny for the heads up.
