Unseasonably Warm Fall

[f1pt4]

So. It's Oct. 9 and they're forecasting between 14-26C for the next two weeks. that 57-78F for you.

I'm wondering how this will effect my trees.

I collected some pretty old and some young larch at the end of September. All put in ground. All turned yellow. All my other larches are still green. I'm hoping this warm weather will assist them in growing out some roots before the deep freeze. All planted in protected, semi-shade beds.

My established trees, none are showing fall color, in fact my privet is full of new growth. Dwarf Lilac popped out leaves out of it's buds set for next year. Mugos pushing needles out of next years buds. Same with spruce, dawn redwood and bald cypress. Field maples are a deep green. Korean hornbeams not a single yellow leaf. EWC's all growing strong. And tropicals and succulents still outside!! Ficus' budding back on thick old branches and trunks. lol.

I mean the trops will come inside eventually, but just wondering how this warm weather will effect all the other trees once the cold weather hits.

I wouldn't be surprised if this weather trend continues until at least the end of this month.

I haven't been doing this long enough to have experience with potted trees and warm autumn weather like this. Anything we should worry about here, or am i just panicking unnecessarily.

Nothing really to do other then water as needed and wait for the cold weather to arrive, which it will certainly do. Ideally, your cold hardy trees will be subjected to several frosts and light freezes over the next several months, which will help to harden them off, at which time they should be put away until spring. The only issue I could see for you is this warm weather continuing unabated into November, followed by a severe temperature drop into the teens, which could potentially cause damage if the trees weren't fully hardened off and ready for winter cold... but there's no use worrying about it. Just keep following the weather and see what happens.

My spruce pushed out a few new buds this week... Idk if it's bcause of the weather, or that's normal this time of year for them

We are still having many days in the 80'sF and Nights in the 60F range. We have had a few nights a couple of weeks ago at 38 - 39F. Bottom line is even though it is warm many trees are going dormant due to the days being shorter. They will continue to do so and not only there but here also there will be enough "chill hours" later in the Fall and Winter to keep all of them healthy.

This Amur Maple outside my front door was green on Friday and as there it is T-Shirt weather, it changed to half orange yesterday because of shortness of day, The stick in a pot Pear in front of it is potted and dropped leaf, to the left is a potted Dolgo Russian crab, still green. They all differ but early on length of day determines how they act or react -



Pretty certain as here Winter will show up there as well, but certain it will be long enough when it does

You only worry about things you can control, the rest are lemons and lemonade.

I agree. My main source of worry are the collected Larch from end of September. Granted they were collected from up north. If they survive, they will probably be the best trees in my collection. I've never collected larch in early fall. Although it is recommended by various growers, and bonsai warriors. I've also never collected larch this old. It was one of those opportunities that may not come around for a while so I had to take it. All legally acquired mind you. 3 out of 5 had decent sized root balls, and thankfully 2 of those three were the really old guys. In any case, fingers crossed all will be well with them come spring.

Being in the ground is likely the best place for them when the weather is being unreliable...

My Cedars have all pushed a bit the last several days, not normal but not bad either. We did have a few nights off/on cold a bit back and returned to warm - they are just reacting to that, all will settle.

Here in Illinois, or on the farm in Michigan, we should have had our first frost by now. Won't be for at least a week or two. I have done nothing to get my indoors area ready. Got a lot of work to do. Oh well.

Me either and too!

For what its worth, there are plenty of guys here who put collected larch in greenhouses. So I imagine yours should be ok with the mild Toronto weather.

 

[Giga]

With the humidity just be on the look out for fungus among us.

I'm getting new regrowth on several trees right now, crabs and quinces. But seems like winter is not coming fast (until it is...) Going to be in the 80's over the weekend here.

I am too, had my black pine want to open some buds, Damn this weather the last few years.

I fear it will only get more and more unpredictable going forward.

That had me outside the last 20 minutes to investigate closely

Toyo No Shiki, Chinese, and Contorted Quince all have new foliage.
Cotoneaster that I cut back hard for the Winter looks like a round shrub again! ARGH!
Goji Berry had been cut back as well, lotsa new growth, sigh.
Chinese Elms, Weeping Chinese Elm, and Winged Elm - not certain if they will ever slow down, no hint of color change either.
Chinese Hackberry, actually looks like it may change color soon.
Rhododendron, looks normal for Fall, darker foliage, setting buds.
Satsuki Azalea still back budding, lot of new leaf.
6 out of 7 various potted Fruit trees still think it is Summer BUT one has dropped all but 5 leaf, weird...
Bougainvillea throwing Bracts, but that was forced.
All Junipers still think it is Summer...
All normal Flora looks good except Petunias which have seen a few cooler nights, normal.

Everything else is inside so some trimming is in order, but all normal.

We have this type of Fall often and although we are listed as 6b it is much more like 7. A town less then an hour NORTH of us is described as a "Semi Sub Tropical" climate... Strange region, nothing like anyplace I lived in New York State. Downside is the Central Air is still running 7/24...

Honest, I am certain everything will see the cold it needs to. What really concerns me is when we have a warm Spring followed by a couple of late frosts.

It's fine as long as we don't go from 60 to 30 in a couple of days like Christmas 2 years ago. If the trees get a few frosts they should be fine.

The warm 40 to 50 spring then down to 30 for a few days after the leaves start to open is a bigger problem

Happens here every year.

I was telling Crystal after leaf drop this year I will be moving everything I can that gets a lot of Sun daily to the shaded cooler part of the yard until we see what Spring brings. Hoping it slows down early budding, might put shade cloth to use again, crazy...
