Cold expected tonight - how low can trees handle?
« on: April 15, 2014, 01:18 PM »
All,

The expected low temp for tonight is 29 degrees. Tomorrow temps will rise to 50. I have an assortment of hardy trees, pines, junipers, maples, elms, etc. and everything has new foliage and buds.

How much protection is needed? Do plants have to go under cover?

Thanks to all.

Augustine

Hi Augustine,

I live in your same zone and I brought all my tropicals in yesterday. I'm leaving out all the pine, maple and azalea. The only one I'm a little worried about is my ginkgo. When its going to be below freezing for a few days I usually bring my maples onto my front porch. I don't know that its necessary though. So far I haven't had any plants freeze to death.  ;)

Hi Augustine,

29 farenheit is -2 celcius, this is kind of cold for new fresh growth...do your trees have shade nets over them? if its open skies they may get frost on them. New buds and foliage on your hardy deciduous trees will die off if they get frost on them, no matter how cold hardy the trees themselves are when they are dormant. I'd protect them from frost and too low temps, maybe onto your porch like izk ?


regards
Herman

Guys,

Thanks for the info.

Isaac - I did in fact place my gingko, which is just leafing out, under the porch. Also the maples and the azaleas which have new buds. (My gingko is a dwarf called 'Chase Manhatten' which I just love.)

Everything out in the open got frosted, temp probably got to around 30. This is a real pain!

Take good care,

Augustine

Snowing here again today as well (-5C or so). I think I am still good as the only thing that I have outside that even looks like it might be coming out of dormancy is my larch, but it should be able to handle a tiny cold snap. All my deciduous are inside now to protect their new growth - have been putting them outside when I know it won't frost.

Here's hoping!

Good Morning all !
Here in northern VT it was 16 degrees F this morning with about 5 inches of fresh snow. Two days ago it was near 80 F.
Most of the rivers and streams are at flood stage and we will be renaming Mud Season to Flood Season!

I moved all the trees that were outside back in. Temps should again be moderate by the weekend!
Hope all are well

Just to be wicked.

Trinidad -
Today's low 74 deg.F high expected in the high 80's and it has with the full moon, rained. Breezy and humidity dropping back down to the low 60's high 50's.

Altogether pleasant and the trees are growing. Beach time for Easter.

Wonderful, for when I return home -  ;D

The fukien teas are dropping all of last year's leaves and re-clothing in high gloss. The Tamarinds have all been defoliated and some flowers may be seen.

Now I ask, why do we end up in these cold climates working for a living. I can't wait to retire in the next year.
Shall still visit the family, but no more living abroad for over 1 month and in Autumn only.

Will remember all of this when the cold room is constructed, and we are growing zone 7 and above trees.
Good Day.
