Yucca rostrata damage from cold? or sun after 3 mos covered?

lucky1 · Post by **lucky1** » Mon Feb 06, 2012 2:33 pm

I'm guessing sun because the Christmas lights kept temps near/above freezing.
They were in total darkness for 3 months.
One of the three has no damage at all...puzzling!

I think you'll be OK. Y. rostrata is pretty tough....not as much when young but they survived -8F here. Some years I don't even protect them and they get buried in snow and they've seen some good cold spells. Here's the leaf damage on my small one after the 08-09 winter. You can see that the center leaves turn yellow but will quickly regrow out in spring. The lower leaves tend to die too. Keep us posted on their progress. They are sun loving plants so keeping them warm in winter with no light may be an issue.

I agree, they don't need much protection. Unless it's from the wet. Keep the roots and the crown dry in the winter and I bet they do good.

That could be sun burn?

Most of the time cold damage comes in the form of spots at the first.

Barb, mine continued to grow after looking like that after -17c last winter. I noticed the damaged occurred on a windy -17c day, versus no damage on earlier occasions that cold with still winds. Mine is against a south wall, gets warmed by the sun through the day. Maybe a combination of warm/ sunburned days, bitter cold windy night (quick drastic changes?). We had only slight snow cover when this occurred (one or two inches).
The positive side, once spring came, I was happy to see multiple new shoots emerged from the base. They grew faster than the recovering main shoot.

Thanks folks, you all make very good points.

Touchy little buggers the first year in the ground obviously.
My little two-headed Y.rostrata that I dug up in the fall because it never really thrived is continuing to slowly die in its pot in the house.

The bonus for the 3 planted ones will obviously be all those leaves will die and presto, a trunk

Plus, yesterday I "found" another potted y.rostrata in the cold building that I had forgotten to plant last Fall.
You know you have too many plants when you find a spare in a corner...

Hi Barb,

you 'found' another Y. rostrata? You got way too many plants!!

I found this plant in my garden the other day.....Opps it's a zone 9b plant!
<img src=http://i30.photobucket.com/albums/c309/ ... G_1411.jpg>

Very much dead.

that comment must be programmed into men at birth

what is/was that plant? could it have been a desert rose (adenium) without the big bulb base?
If so, you're a very bad person for letting it die, Tim.

Are those needle palms in the back ground? And what are ther cactus, all left out all winter?

Hi Barb,

it's been a long time since I purchased that 'dead' plant......I think it was a south african Pelargonium? Got it at a plant convention up near Boston. It 'was' cool. PS, I'm rolling on the floor with the 'too many plants' comments. That's what my wife says!

Hi Aaron,

nice eye. There are some needle palms, sabal minors, sabal palmettos, a large nanital and some Trachycarpus waggie 'korea' plants. The cactus were seed grown from 1992 (real fast huh?).....most are the super hardy stain of Carnegiea gigantea which can survive up here in zone 6b as long as you bring them in your garage every night so you can break your back.

Funny

Cant wait too see everything planted.

Barb - THat happened to my Yucca Filamentosa last spring. We had really warm temps, really fast. The snow melted within a few days, and lots of the leaves fried. There was a difference between sunburnt and frost killed. There were a few parts that were black and mushy..... Definitely frost damage. THe tanned patches are the same thing that I get on my indoor plants when i dont harden them off properly.

Also, you can never have too many plants. IF someone says that to you, its a sign you need MORE!

lucky1 · Post by **lucky1** » Thu Feb 09, 2012 8:27 am

black and mushy

yeah, that's easy to figure out.
Not there yet fortunately.

So it must be sun damage from being in total darkness for 3 months.

you can never have too many plants

Agreed, but when you find one hidden in a corner by other stuff, it's almost like nursery shopping at home.

Tim, OK that comment then is programmed into both genders

You folks are cracking me up.

My wife hauled in a potted Yucca rostrata for me last night without even asking.
Didn't have the heart to tell her we weren't evening getting down to freezing. Thought that counts, right?

TimMAz6 · Post by **TimMAz6** » Thu Feb 09, 2012 7:08 pm

Your wife loves you a lot if she's hauling in a Y. rostrata......that's hardy in your area??

TerdalFarm · Post by **TerdalFarm** » Thu Feb 09, 2012 8:33 pm

Should be, after last winter!
W says the large potted CIDP was the worst to lug in

Barb looks like they will make it. Did the Rostrata needles touch the plastic while covered?

That occurred to me too John.
the plastic appeared to be at least 1 inch away from spear tips.
Unless wind whipped it up and down.

And with no snow or rain, there wasn't anything heavy to drop the plastic.

Dead parts don't seem to be expanding.

They haven't been watered since September ... 4 months bone dry under an overhang.

Okanagan desert-palms · Post by **Okanagan desert-palms** » Thu Feb 09, 2012 10:15 pm

Barb they are probably a little thirsty. I watered everything planted out last week since we have been having a warm spell for a quite a while now. Hope it lasts.

John

probably a little thirsty

I thought the condensed moisture under the leaf bags would be enough...

You watered everything????
Thought they didn't need water when soil's cool/cold.
I haven't even watered the Trachy in the heated palm hut for ... well...maybe I did once. Can't remember now.
Ground was never frozen in there.

Aaaargh!

Barb I water at least a couple of times in the winter. I almost lost a S. minor a couple of years ago due to dying of thirst.
