Re: Cult: US Heat Map
From: Sandy Ives <rives@home.com>
The heat map zones should be readily, and easily, available from the America
Horticultural Society. I believe they were instrumental in recognizing that
heat was just as much as problem as cold, then going out and doing something
about it.
I have no address, but any gardening club worth it's salt should be able to
direct you further; there are also the major botanical gardens in Washington
D.C., Brooklyn, and Denver (among others) should be able to go further.
This was taken from the AHS web site at www.ahs.org. I suspect they would not
object to either my copy from the site, nor the spelling correction.
"AHS Members receive The American Gardener and the Directory of Member Benefits
free as a member benefit. Additionally, members can download most GIS Bulletins
and a
small version of the AHS Heat Zone Map from the Members-Only Pages"
and again...
"Use the AHS Plant Heat-Zone Map in the same way that you do the Hardiness Map.
Start by finding your town or city on the map. The larger versions of the map
have county outlines that may help you do this.
The 12 zones of the map indicate the average number of days each year that a
given region experiences "heat days"—temperatures over 86 degrees (30 degrees
Celsius). That is the point at which plants begin suffering physiological
damage from heat. The zones range from Zone 1 (less than one heat day) to Zone
12 (more than 210 heat days).
and...
"For more information on Public Relations email Mary Ann Patterson or call
(703)768-5700 ext. 21. "
The individual membership is 35.00USD per year, but the benefits of membership
seem quite good.
An alternative would be to join your local garden club and agitate to get a copy
of the AHS publications.

whose TB season is drawing to a close a week before the show. Siberians only...
if we're lucky)
