Default Create your growing Zone Breakthrough

Just found article regarding growing bananas in freezing weather. GREAT!

March 14, 2009

One of the banes of gardeners worldwide is cold temperatures. We even have zone designations to tell us if our area is too cold for certain kinds of plants to grow in. But what if you could change your hardiness zone without moving and without a greenhouse? This revolutionary idea is actually a breakthrough on the verge of coming on the market - read on for a BIG surprise . . .

Gardening picture
Science Tackles Zone Envy?

As a scientist, I am always on the lookout for information relating to innovations or breakthroughs that will make plant growing easier. One problem that has seemed insoluble is local weather that is too cold for the kinds of plants a gardener would like to grow. Not only does a colder climate limit plant choices, but it also limits the length of the growing season. So even if you can grow certain plants, you might not be able to grow them to fruiting maturity. If your gardening goal is to grow produce, this is another limitation that cold places on your activity.

Until recently, the only solutions have been to invest in an expensive greenhouse setup or to move to a more favorable growing zone. But science has advanced a third solution, based on the very physiological principles that enable some plants to be hardier than others. Imagine a product that can be sprayed on your plants a few days before frost, and then imagine sleeping soundly the night of the frost, knowing that the sprayed plants are safe. Finally, imagine waking up the next day and finding that your plants look as good after the frost as they did the day you sprayed them.
Imagination Becomes Reality

Recently I learned of some important work that has been co-developed by Dr. David Francko at the University of Alabama. It seems that this good doctor experimented with several compounds now in use either in foods or in food production. He discovered that a unique combination of five of them together, formulated into a water-based spray and applied to plants, improved the cold tolerance of plants from 2.2 to as much as 9.4 degrees Fahrenheit, depending upon the plant species. For those who live in zones where frost or freeze occurs just enough to prevent the growing of truly tropical plants, this means the difference of one or two hardiness zones! In fact, Francko stated that, when discussing banana plants, the effect of the spray was to change your hardiness zone to one 200 miles south of you! His example was that growers in the Mobile, Alabama area who sprayed their plants with this formulation would get the same effect on their plants in a cold event as someone in Orlando, Florida with the same plants, but who did not spray them. In other words, the hardiness zone of Orlando, Florida would apply to Mobile, Alabama when the plants are sprayed!

Two mechanisms affect how hardy plants are to cold; they are a natural cryoprotectant, or freeze inhibitor (lowers the temperature at which freezing occurs), and a means to prevent or minimize cell damage even in cases where ice crystals do form within the cells. This new product enhances each factor by both lowering the temperature at which damage is first visible and lowering the temperature at which a plant would finally die. An example shown is an unsprayed banana plant showing severe damage after 20 minutes of exposure to freezing, while a sprayed plant still looks fine after three hours of exposure to the same temperature!
I'm Sold; Where Can I Get It?

The product, called "FreezePruf", is slated to be marketed by Liquid Fence soon. A date for release has not been set, but my correspondence with Dr. Francko indicates that it should be within a month or so. The product does not promise to enable growers in Ohio to leave true tropical plants outdoors all winter, but it will extend your growing season several weeks at each end and reduce the need for other, more expensive, freeze protection methods. And for those who live in a marginal zone just a bit too cold for tropicals, it might just give you the edge to go truly tropical!

FreezePruf

Thanks SG. Here is another thread on its progress for any interested:


Extra 7 degrees goes a long way

I'm always worried about something that changes how cells naturally work. Personally, I'll stick with dragging my pups at the end of their 1st yr into the shed to Hibernate at 30-32F so that they can be planted out after Night temps are above that.
Truth is, being the child of Survivalists and EOTWAWKI-types, the big point of growing your own is to provide for your family when the Grid goes down. Being dependant on something you get in the mail that is made in a lab is a bit counter to that worldview;>!
Cheers,
Pat

Will this really make a difference for zones 7 and 8 since low temps will kill the foliage even with FreezePruf? Plus, the banana's roots wouldn't grow in the cold, freezing weather that this area experiences, in fact they could rot in the wet southeastern winters? I'm excited about this product, but I don't know how useful it would be for bananas in reality.

I think its mainly to push the first frost date to a later date. It may add a few weeks before they are damaged. You could have a low 28F and next week it could be 80F.

I wonder how much gratuity from the company the author earned for writing the article. It reads like ad copy to me.

LOL! You tell 'em Richard, sheeesh.

I don't know if anyone remembers, but last winter '07-08, I believe BayNews9 did a piece on Lakeland's freezing strawberry problem. In that headline they were discussing the use of Anti-Freeze for cars. They said it wouldn't hurt the plants but probably not safe for consumption! I got pretty cold here a few times hit freezing over night, but I didn't lose a single leaf, and I certainly did not use Anti-freeze.

Anything that is preceded with as much hype as I have seen with this product can only disappoint.

I remember a similar product claim about 20 years ago with the same promised result....I wonder if it is the same guys?

I do not trust it, but I'll allow all of you to prove me wrong.
