All of those should be fine with 19. The only problem I see with those inclosures is the problem of damp dew going to the spear and causing spear pull. After it is cold, the warmth of the sun causes condesation on the inside of the enclosure which trickles into the spear. Make sure you let it breath EVERY DAY even if the temps are below 19 outside.

wxman,
Everything looks well protected! I'm curious to see how your Sago does, are you using the same set up with it?

Steve

Yes I am using the same setup with it. 🙂

Hope your Sago does well! (and everything else too)
I have a couple planted inside the green house, but still have yet to keep one planted outside, let us know how everything does!

Steve

Here's the two in ground Sago's,

They haven't flushed since planting, but the stems have gained size,

The robusta in the second photo was planted at the same time as the one in the yard,
(it had a enclosure around it for the winters, when the green house was expanded I just built around it 😀

Here's a different angle,
(fronds are tied up for the winter so I can walk around it)

Steve

Great color on those sagos, Steve.
They'll really take off in '09.

That robusta is certainly named correctly!
It'll be interesting to see the growth comparison between your two. 😆

Just an observation on the sago:
I also have one whose caudex has dark coloring (almost like the ones in the wild look after grassfires).
Is that natural? Why do some have it and some don't?

Barb

Barb,

I'm not absolutely sure, but I think the caudex darkens up with age.

Yours is looking good! Is that the same one whose fronds dropped last winter?

Steve

Yup, that's the one, Steve.
But it was summer if I recall.
It wilted in the cheap clay pot (in full sun all day, every day), when the other older one in same conditions was fine.

You'll remember it was Jody who came to the rescue, advising tying up the fronds with string and watering the heck out of it.
Worked like a charm.

Wxman, welcome aboard.
Nice specimens you have.
That trachy will be pushing you off the path in a couple of years... 😉

Barb

A shot of high N fertilizer in mid May will usually get those sagos to flush,I used lawn fertilizer on mine and it stareted a new flush within a week after going two years without.Be carefull not to use to much as it can burn the roots

Whatever it is, it can sure take a lot of abuse!

On a night when it was -7*F/-21C with winds of 20 mph, an animal clawed it's way through the plastic.
(apparently looking for someplace warm, can't really blame it 😀

Have things taped back together,

Not sure how cold it got in there, most of the Aloe melted, even a couple Sabal minors in containers fried.

The Washingtonia is looking a bit trashed, but still pushing a new spear 8)

Steve

And we are like the palm trees are not ukryvaem. This winter is warm. Min was in Zone 9. 😆

hi limoncik.
How nice your winter minimum temperature is a Zone 9. 😀

We in British Columbia have had one of our coldest winters in many years -27 C 🙁

Barb

limoncik,
Good to hear you're having a mild winter 8)
no covers needed this year?

Steve

Here it is, looking a little rough..................
It has bounced back before, I'll keep my fingers crossed 😀

Steve

Steve I hope it makes it. I don`t remember seeing it look so rough from previous years.Is that a seed grown Bismarkia to the right in the picture?
