It's official: Gardeners and farmers can count on warmer weather. If that's you, it might be a good time to rethink those flower and vegetable beds for this year's growing season.

That's the word from the U.S. Department of Agriculture, which released a new version of its "Plant Hardiness Zone Map" this week, the first update since 1990. The color-coded zones on this map of the United States are widely used as a guide for what perennial flowers will survive in a particular area, or when to plant your vegetables.

My area has changed a wee bit for the warmer.

I saw a Master Gardener interviewed about this map update this morning. He said the magnolias in Pa. now have a chance to grow bigger and show off those pretty big flowers.

My thought was that in a wicked way for a little while climate change may be seen as a positive. But we should enjoy these days right? The irony of it all.

I guess in our northern areas it could be a little plus for gardeners. Not for those people and crops in the deep south though.

It might not be a good development for some fruit growers. Apples, pears and stone fruits require a certain number of hours of exposure to temperatures at or below 45 degrees.

It's also not a good deal for southern tomato growers. The evening temperature has to get below 90F (or so) for the flowers to fertilize and produce the beginning of tomatoes.

I guess that is why the stupid daffodils are now sprouting in Arkansas in January... (yeah, they're up already)

We desperately need some freezing days here, to kill off all the dang bugs.

There is likely to be both good and bad to this, but one thing we know for sure-- it will certainly be different! I hope we don't lose the last of our wildflowers...

This is old news. In fact, areas nationwide should be about 5 - 10 degrees warmer on average than they are now. Why are they not? Artificial cloud cover reduces solar radiation; being outside all the time I notice things like warming trends lead to 'lingering contrails' which just so happens to induce a cold front. I think upper 50's in January is unseasonably warm, but without this artificial cloud cover temperatures would be spiking into the 70's and is a variable the weather reports do not include and is why they are off on their predictions by 10 degrees.

During the solar flare on tuesday, massive cloud cover was noticed. There was a time this artificial cloud shield was out from the sun and it felt very hot on the skin. The dangers of this are twofold: we are adapting to the changing climate and artificially maintaining the old environment leads to very few people realizing that the climate is dramatically changing.

This is not speculation, this is empirical data. The only speculation is whether it is intentional or not and from the years of watching the skies I believe it is intentional due to the strategic placement of these artificial clouds in relation to the sun and major population areas.

I'm guessing that the blue areas are the areas where growing is still possible. In that case, my home state of Wisconsin is hangin' in there.

No, that is the new projected zone for the bread basket. Good for you, bad for me I guess.

The map may be indicating changes for some, but I am still in pretty much the same zone. Frost, ground temps, water and soil nutrients still determine the growing season and productivity. I can do something about the latter two, but short of stretching a plastic canopy over the garden, there is not much I can do about the former two.

Won't thaw come a bit sooner if the temps are warmer? I recall there was no killing frost here after May 11 this past Spring. We usually wait until the 31st to put tender plants out. I'll chance it early this year. I may have risen only 2 degrees or so on the zone map, but this winter in New York State has been especially mild, little to no snow, and lots of rain instead. I am wondering about the creatures of our wild, and how they will be affected. Even our ponds and lakes have had very little ice this season; no skating so far - :(

On average, the answer would be yes.... and the average day for last spring frost is getting earlier. Still doesn't mean frost won't get you, if you wait til after that average day. Besides, I have tried multiple ways to have tasty ripe tomatoes by July 4th. I have had ripe by that date, but not tasty. If I settle for late July or early August, I get really tasty tomatoes. Same principal for most of what I enjoy getting out of a garden.

Gotta have that sweetening, ripening sun. The squirrels around here seem to know the day before picking time.

Well, it certainly doesn't surprise me. Although I live in a micro-climate (so it's hard to guage how the map applies to me), I am now colder in winter and warmer in summer. More wind, too, probably due to changes in the surrounding climates.

I had the most fantastic peaches after I bought and planted a Red Baron peach tree. It has done extremely well, except we had a late freeze and I lost EVERY BLOOM! I darn near cried!

I am still babying my loquats.

In the past 10 years, it has moved up from the Land Between the Lakes area, south of Paducah, up to the southern edge of Jefferson County, Louisville... So, it's on its way!

We need to hire goats to eat it all up. They love brush. Imagine goats on the payroll!

Goats or sheep, either one! They can both do a good job on kudzu! :-)

According to the new map, I went from zone 3a to zone 3b, but, aside from this winter, every year we see temps that are -40 or lower (which should put us in zone 2b to begin with). Last year our coldest day was -46. So far this year the coldest has been -28. Believe me, Im not complaining about a warmer than average winter, or that the map has changed, however I am not going to take the chance of planting too early. Last year we had frost June 3rd and again on Labor Day. All my tender plants go out on June 1st and I cover them if need be, but even covering doesnt help if temps get down below 28. Its always that first frost in the fall that gets me because by then the plants are too big to cover. Now, if Santa would bring me the greenhouse Ive been asking for, I could start planting in April and life would be good! ;)

Have you tired to extend the season with one or more of these?

Im thinking something like this:http://www.shelter-solution.com/hobbyist-greenhouse-kits/ so that I can just roll up the cover during the summer months and put it back down in the fall.

I did have a cold frame once that was made out of old windows. Ended up using it as a brooder box for pheasant chicks.

When we lived in Ct. I always used coldframes and had a greenhouse window in the kitchen. It was a helpful beginning to the garden - but the deer!!! Always smile when I eat venison.
