Freezepruf's main ingredient Propylene Glycol

[Axel Amsterdam]

After reading all the disappointments around spraying freezepruf on palmfronds, i wonder what would happen if palms would be watered during their growing season with the main ingredient of freeze pruf: propylene glycol. PG is an environmentally friendly form of antifreeze. There are reports that suggest that PG actually enhances planth growth when applied to the roots.

I have no doubt that the inventors of freezepruf thought about this possibility but i have never read any reports on it. Maybe it could add an extra few degrees of hardiness when palms take up PG and distribute it through the cells of the meristem and fronds? Anyone/any scientists around here with ideas?

Sorry but ... Just my opinion.

This disclosure that Freezepruf is propylene glycol is really quite funny! Freezepruf turns out to be a pretty mundane solvent.

I havent seen that product available here. There is one here called Envy, quite expensive to buy, so I read the fine print carefully, only to find that it states (practically in microfysh size need I mention) that it is ineffective at temperatures of under 2 degrees C !! Frost doesnt even form at my place before it reaches minus 3c, so I never bothered trying it. I still say that a few doses of a seaweed liquid fertiliser in autumn is the best protection one can apply to exposed plants.

-3c in Queensland? Really?

[peachy]

Yep...it shocks everyone. The western suburbs of Brisbane, get freezes every winter. Go out to the Granite Belt and it can be minus 12 or more. The Darling Downs frosts badly and nearly every night seeing temps of minus 4 to minus9 !! Charleville and Birdsville...all those places out there are wretchedly cold too. When I lived on the Darling Downs, I used to drive to my friends house at Woolbrook, near Walcha Rd, just to warm up

While my experience with Freeze proof is far from stellar I have to say that if used in ample amounts it does appear to offer some protection. The only Hydriastele that is alive in my garden is the one I drenched with the product. I lost all of my Hydriastele's including the same species that was right next to the only surviving one. However, this palm did not come through unscathed, but it will survive. At $100/gal and an application cost of $33/gal, it can get very expensive to buy an extra degree or two.

Assuming that the palm is in near dormant stage (for some of us in the lower zones), why would you want to stimulate root growth? Not sure what the consequences would be, except that if the plant were in near dormant stages, that it probably wouldn't stimulate the roots. It would be an interesting experiment with some palms in containers though, where you could observe the root growth and didnt care if you might kill or screw up the palm.

This disclosure that Freezepruf is propylene glycol is really quite funny! Freezepruf turns out to be a pretty mundane solvent, less than $10 per gallon! PLEASE! will someone tell us what the vendor charges for it? Some of us would be extremely grateful!

Best Wishes,
