Nahunta, Georgia - what USDA hardiness zone?
Comments (5)Yet why USDA does not update its own maps or make them more refined with more detail showing. I was in Bluffton, SC and it has adult old palm trees growing that would not survive in a USDA zone 8B. It must be 9A or even higher. I think it's time for USDA to review its 20 year old hardiness zone maps. Do you think it makes sense if USDA after rejecting Arborday maps review their own maps? The only reason why USDA won't I think is the artificial cloud cover they are creating and thus cooling the climate down and back to the old hardiness zones. Like this winter they created a freak snow storm in southern SC by spraying clouds, an ugly mist in the sky which lower temperatures so much that it started snowing and my palms died that would usually survive in this area. I also spent 50% more on a heating bill last winter. So I think this could be the reason why USDA won;t review their :hardiness map" because they are not sure themselves where the climate will be with all the artificial cloud cover making going on in the sky. And only a very busy person can not notice what's happening up in there. I will go South FL to make sure my palms survive. I hope no snow in SFL next winter.... ;-)...See MoreSome USDA zones for various Northwest locations
Comments (17)Tom, I think the answer is it depends on the airport, but usually, yes airports are colder. The main reason is that airports are invariably on flat land and frequently on valley bottoms which are frost pockets. Some of them (i.e. Sea-Tac) are on plateaus which aren't as cold as valley floors but still have inferior drainage to sides of hills and any kind of sloping land. Some people live on flat land but a lot of people live on slopes and hillsides especially closer to the water (it would be fun to study what percentage of residences are on slopes of, say, 5% or more). But certain airports should be considered as exceptions because there is so much development around them - including Sea-Tac, Boeing, and Paine Field. All of them are in the middle of concrete jungles and thus probably aren't any colder than the surrounding areas. By contrast you have airports like Olympia and Spokane which are relatively undeveloped themselves, not surrounded by a concrete jungle and definitely much colder in winter (verified by locals, temperature readings and indicator plants) than the cities they represent. I have some support for this idea. If you plot a running average of the lowest temperature every winter for Sea-Tac there is an abrupt rise during the 1950's-60's that is much greater than that of other weather stations in the region. This can only be attributable to the amount of development in and around the airport during that period. I provide the raw data for that here (although the article is actually about something else): http://www.desertnorthwest.com/articles/enso_effects.html That's interesting that Port Townsend records at the fire station - it's about 170' up and 1/3 mile inland, on top of the bluff; meaning that downtown itself, and places like Fort Worden, are probably even milder. Is there a list online somewhere that tells you where each weather station records? I'd love to see it. Here's a quick survey of the coldest temperature during the December 2008 freeze in a few Port Townsend Locations: Jefferson Co. Courthouse 19F Madison St. and Foster 17F Port Townsend Paper (right on the water) 22F Woodland Dr. (near airport) 13F Far Reaches Farm, Hastings Ave. 8F (says them)...See Morethe best 'hardy' palm tree for zone 6a
Comments (55)Hi Treeguy. What part of WNY are you in? I'm in Rochester NY (City NW) and am growing Musa Basjoo, Musa Sikkimensis, and Musella Lasiocarpa in-ground. I was told that the Sikki and the Musella would have to be dug up over winter, but I left them in-ground very covered up in mulch and they're doing great. This was their first winter here. MY palms are all in pots and while not in-ground, they ARE in an unheated porch out back. Monitored temps dipped as low as low 20's some nights with usual highs in the upper 30's/low 40's. There was a brief super-cold spell where the lows read in the teens, but daytime highs were 30's. My palms are T. fortunei, T. wagnerianus, T. takil, T. latisectus (everyone expects this one to die, so I'm thinking about mailing it to a cousin south), and two Butia capitata. The pots aren't insulated or anything, so I was lucky.... but they lived. I can't plant in-ground until I buy a home, but I'm definitely planning on it. I have waggies which I germinated from seeds and they spent winter out in that shed too, but I brought them in during the cold spell....See MoreUSDA Zone Debate (What Do You Think?)
Comments (117)I wouldn't go by the lowest temps that have been happening in recent years. I think thats where part of the problem is with the USDA zones. They only used part of their data. Although they do have a reason behind it, I still think that for the areas that do have more data they should have just used them anyway. Thats too small of data to be very accurate in my opnion and do not take into account if they have been recording a warming or cooling trend. And if thats the case are they likely to continue? And what about record cold winters and how often they will play out? Its hard to say. But what I like to do is look at as much info as I can and take the average of all data collected about each years low in an area. I tend to think it is more accurate and gives a better picture of whats going on and what to expect. The USDA is just one tool or a guide to help you out.It may have its erros. But at least it narrows down the list and keeps those that don't know so much about gardening from wasting money on things that will never have a chance.(although that doesn't stop people like me from zone pushing or trying anyway. lol)It was never meant to be set in stone. Each year is different and so is each area. Best ways to truely understand your zone/climate is trial and error. As well as looking around and see what other people are growing long term. But I am down for a better system. Anyone else? lol Unfortunatley I don't think any system will ever truely be accurate. Theres just too much to consider other than temps. Youn have soil, elevation, moisture, health of plant and list goes on. And not to mention each local micro-climate... - US_Marine...See Moresubtropix
