Thanks Gwenn.  I'm still in western 10B.  I am interested to see if other members have any change to their zone.

Thanks for the information.

I see that the map is based on data through 2005. My zone 9b place in Highlands County, Florida has had quite a few nights down to about 20 degrees in the last 3-4 winters.

I've heard that even modest overall climate change can cause extremes of temperature, etc. in some areas.

Still, I'm hoping that this is just a short-term trend. Someday I'd like to eat a loquat.

Where are you having trouble growing loquats? Lake Worth or Highlands County?

I'm in 10a as I always suspected from observing the local yard plantings. There isn't much of a change in the St. Petersburg weather records though.

Never had any problems with loquats fruiting in Gator Country (Gainesville, Florida).

murahilin:   I've had the loquat trouble in Highlands; each year the flowers or fruit are killed by low temps.   So far I've saved the limited yard space in Lake Worth for mangos and such.

Are fruit flies a problem these days for loquats in Florida zone 10?

I had always thought they grew great in central Florida.   Maybe it's a microclimate issue for my yard / neighborhood.

It seems most of California experienced a bump up in zone. Interesting to see that almost all of Los Angeles basin is a solid zone 10b. I believe the Los Angeles basin gets a lot of the warmth at night from the concrete and asphalt density. I can spot many +15 year old Mango and Inga edulis trees planted in the ground through out Los Angeles.
Grow mainly fruits, vegetables, and herbs.

Time to plant out a bunch of Guanabana with a nice bamboo wind break, or better yet, sapodilla!!!

My zone bumped up from 9A to 10B (92646).  Zone 10b = 35-40Deg F - which I consistently observe...

I guess Florida had a warmer climate back then.  :) lol Temps have been the same on the same wave-like pattern.  We've had cold and mild winters before. I guess they change the temp scales for each zone, like what they did to the Tornado strength scale. The F scale vs the EF scale.

Officially, Im now in 7B which is 5-10 degrees but in practice, its more like 8a which is 10-15. I dont recall it getting below 10 degrees, and even 15-20 degrees is rare

New york is pretty warm, it's only 6-8 hours from Montreal and there's a big difference.

thanks! now I need to change my profile! i'm in zone 9b i guess...what's the zone map from 1955 look like??? lol ;)


Here is Bloomberg article on the new zones
USDA ‘Plant Hardiness’ Map Shifts Temperature Zones North http://www.bloomberg.com/news/2012-01-25/usda-plant-hardiness-map-shifts-temperature-zones-north-1-.html Not that I believe it. Lots of this global warming hysteria has been exposed as junk science as far as I'm concerned.  It is beyond laughable to classify CO2 as a pollutant. Water vapor is a stronger factor than CO2 in the greenhouse effect. Solar cycles are very influential.

Aw, I'm still in 9a. :(

 I heard that many years ago it used to be a lot warmer here and they used to grow a lot of citrus commercially. Anyone know what zone Jacksonville was like 20-30 years ago?
