Maples ready for the 2021 oven...

[Mike Corazzi]

As you may know, my climate roasts trees. Especially maples.
This year I am not trimming a damn thing to see if extra foliage and stems will stand the heat better.

Doubt it.







And no, since my one place to take pix broke, I have no decent place to photo them.

Though about a mister and/or filtered shade for the hot months...
I will be going through my first summer with one this year.

That's 2 screens behind them and it is afternoon shade.
Pretty well sheltered from wind.
We shall see.

I want a maple but I'm afraid the climate here in SoCal will be difficult to keep them alive in. It's probably milder where I am than where you are, so if yours make it, I might try. I spent a couple years in Davis, so I know how hot the summers up there are.

This



Turned into




and then turned black and died. Some said virticillium wilt but heat didn't help.

NO MAPLES FOR YOU !!!

 

[Hack Yeah!]

Bummer

You Cali dudes should look into montpellier maple. I don't know much about them myself, but they are mediteranean trees. Chance that they can handle a little more heat and sun. maybe not.. just spitballing

 

[Mike Corazzi]

I had a Campestre that did pretty well. Really big though with long internodes.
gimme an olive.

Shade cloths doesn't help? You must be no where close to Al...since he can grow maple with his eyes closed.

So, I got curious to your plant zone did a search...Trident end at zone 8. Time to just pull yourself up by the boot straps and grow what will thrive in your zone. It's much more pleasant experience finding success.

Five years in...why do you keep trying to stack the deck against you? I don't understand... I honestly don't. By now...have you not considered it? Growing plants zoned for your location...

You've never tried sango kaku? They withstand hot temperatures very well.

I've been paying attention to Hardiness Zones, but this made me wonder about it.

I live in 10a, but to me, it's very mild. It (almost) never gets down to freezing and it rarely gets really hot. That made me wonder how the hardiness zones are calculated, so I looked it up.

Apparently, it's strictly the lowest average temperature for a place. That's it. No mention of how hot or dry it gets. It seems like going strictly off of zones would only be useful for determining how much cold your plant can take. Is this REALLY the best way to determine the right trees we might get??? It just seems like there might be many other important factors that we are ignoring.

Here's an example: I'm in 10a, but Las Vegas is 9a. Vegas gets a bit colder than here, but MUCH hotter and dryer for much longer.

For sure, there are microclimates...I'm in one. But for a few who struggle. With trees frying in their location. There is something that needs addressed...as to what can we do to find success.

You need to look at the AHS heat zone map when it comes to growing things that like it cooler. My town is considered (heat zone) 4 by the oldest maps, and zone 5 on the newer ones but I have been keeping track of the temperature myself for years and it turns out I'm actually in zone 6. Where as some in hardiness zone 8 in Oregon might only be in a heat zone 2 or 3. Hardiness maps are a very small piece of the puzzle. Don't get me started on precipitation and humidity

Such as: look around and see what is growing. I've been to Lincoln. There are trees there.

Yes, the heat zone map says the number of days a year above 86F. https://ucanr.edu/blogs/blogcore/postdetail.cfm?postnum=21544

I'm in heat zone 4, which is 14-30 days per year. Lincoln, CA is in heat zone 8, which is 90-120 days per year! That's assuming it hasn't gotten any warmer since the map was made.

Meanwhile, I'm guessing @Wulfskaar lives along the coast? In which case the ocean greatly moderates the weather and the heat zone is lower.

Edit: Not that they're exactly like tridents or Japanese maples, but there are some species native to the southeast that you could try - the red maple Acer rubrum and two variants on the sugar maple (Acer leucoderme and floridanum). For the red maple, sourcing a tree from the southeast would be important.

There are maples and pines of all types around the neighborhood, as well as a zillion other trees I see around... basically... IGNORE the hardiness zones.

I wonder if I could make some $$$ by creating a new zone map that takes multiple factors into consideration, as hardiness maps are good for only a fraction of required information.

Yes, I'm along the coast. It's very mild for most of the year. The worst we get is generally the hot and dry winds associated with Santa Ana wind events. Otherwise, it's just always room temperature (not really but close).

 

[Paradox]

That heat zone map is pretty cool, but only really useful if trees are labeled as to what heat zone they are able to thrive in as they are labeled for the hardiness zones
I am in zone 4 according to that map

SAGUARO TREES !!!!
