Has anyone tried Freezepruf?

[Sandy Loam]

For the first time ever, I tried spraying Freezepruf on some of my palms/plants that were most tender, but I can't really tell if it worked to spare my plants from damage. It has been a cold January, but not cold enough to really damage anything in a significant way.

Has anyone tried this product and had success? Is it a myth?

OK. Sorry, I wasn't aware that there had been so much discussion about Freezepruf results already. I guess this thread ends here.

Thanks for pointing those links out, Keith.

Never tried freeze pruf, but I did use wilt pruf on my Camellia sinensis this year because they tend to dry out in winter. I also sprayed it on my potted palms; after a low of 5F the chamaedorea radicalis is dead (no surprise) but the leaves remained perfectly green throughout the entire event and beyond, and the large potted needle has spear pull. Interestingly the Camellias look better than they ever have during winter.

Based on my experience with wilt pruf and after reading about what freeze pruf has done to palms, I'd say these products are more effective, if they work at all, on dicots. Palm physiology is different so maybe that is a factor?

No, sorry on my part. Putting them up like that was kind of rude. I was just in the middle of a search for something else when I saw your post. Took me just a minute to pop them up, and then I went back to something else.. Like you and many others I would love to see something that works in these regards.

Sorry, still think its snake oil.

Here is one example from their PDF... So what they did is put the actual numbers with freezepruf, and made artificial temps above that. Phoenix canariensis starts taking damage at 25? LOL

Palm -Canary Island Date - Palm Tree

Hardiness Zones 9-11

Without FreezePruf Damage

1-2 Hrs @ 23-25F

Without FreezePruf Mortality

1-2 Hrs at or below 20-22F

With FreezePruf Damage

1-2 Hrs @ 20-22F

With FreezePruf Mortality

16-18F

Yes, I see your point here Enigma. I actually have a CIDP that I bought as a small plant (probably 1 year old) and stuck it outside in a pot here in Seattle (zone 8a) last summer. I left it out all Winter just to see what would happen (I only paid $6 for it). It has taken months of rain, temps down to 16F, but probably more significant is that we have had now probably 3 weeks worth of temps below freezing at night. It is still alive, albeit not looking great. But no spear pull and it does not appear to be dead. So bottom line is CIDP is way hardier than what Freez Pruf is saying. Nobody is impressed with a mature CIDP being able to handle even several days below 20-25F, so these are not groundbreaking results here. I would guess there are many CIDPs in Nor Cal that have taken years worth of winters with intermittent temps dropping into the low 20s.

Keith still secretly uses it

Freezeproof is useless for frost protection but it's useful as an anti-transpirant in drier climates to help new plants get started and reduce water stress.
