Mine are in their normal spots, I only put sphagnum moss on the soil is the only difference. Maples of course are always in dappled sun, except for the trident, which gets lots of sun. I'm not there to see how they are doing, as I'm working the fair (looooong hours) but I'm sure they're good. It's actually not been too bad for heat this summer, I don't think we've cracked the triple digit at all, and we usually have a couple by now.

Nothings really changed even though we hit triple digits here- I just moss and water accordingly. I have the tree's set where they each get the sun requirements each needs - even in this blasted heat

Depends on the tree. Live oak and western oak in full sun all day. Pots get white cloth covering to shield them from the sun. Others, like cedar elm and bald cypress, get partial shade or shade in the afternoon. Japanese, trident and amur maples get three hours morning sun. Hornbeam get afternoon shade, or full sun (in ground). boxwood six hours of sun until mid-afternoon with shade on their containers..

We've had brutal heat (upper 90's) with stifling humidity (last Wed. or so it was 89 degrees with 80 percent humidity). High heat has broken for the most part, but now we're in for torrential rain...Cooler temps next week (relatively--mid to high 80's)
I'm surprised you shade your cypress, and I'm wondering what issues you've had that have made you take this precaution? The only time I've ever seen a bald cypress suffer from direct sun, it was in the spring a month post re-pot and root reduction, after a few warm, breezy days with low humidity.

Because my backyard is 30 feet by 30 feet not enough room to put everything in full sun all the time. But you know best I guess.

Hmm interesting I would have used this topic to get solutions.

[1] If I use natives would they be harmed by air temperature / sun exposure

[2] Would they be harmed in Bonsai pots

[3] Is this what causes the soil problems, insects, etc. ? Because I am trying to grow
out of zones ?

[4] If I have favourites, should I do more to protect them [ the Canadians winter maples
in refrigerators for example ]

[5] When or Why I will quit Bonsai will all of this pot moving and I just get fed-up

Solutions to be shared [ as some have already done ] and not just complain.
Good Day
Anthony

??? I just asked a question of someone whose been keeping cypresses a lot longer then me, and thought I might learn something from you. Fwiw, I've got limited sun in my yard, so I get it.

Ha Rockm,

I bet your yard is flat and not on the side of a hill, where the lawnmower can flip
over and tumble after you :)
Just being an idiot, but the yard here is very sloping.
Good Day

If that's all there is to it, forgive me.

FWIW, I have had BC start yellowing out in full sun by mid-July. This happened particularly when I kept mine in standing water in full sun. I've also noticed that BC can and do get sunburn, which can become apparent later in the growing season.

I admit it is a bit of extra work but that is why I flush mine daily. I also have found if the break bud early because of a warm Spring they are quick to defoliate when hot with a frost while in the Sun. They rarely produce new foliage the remainder of the season but normally grow proper the following year. Gymnastic plants depending on where one is located and the methods they use for certain. They are tough though and so far over several years I see their only enemy to be Nature itself.

Does the sunburn look like little brown spots on the leaves?

Not spots. It is an overall lightening of leaf color, from yellow to even lighter, especially on leaves that on the areas most exposed to the sun--apex and branch ends. Leaves in shaded section of the tree--interior--don't have it.

These umbrellas are working great to provide shade in the afternoon in Texas with these Japanese maples. Last year without the shade they were crispy. Extra watering also.

30% shade cloth, humidity trays and burlap underneath that I wet down daily. we have had 95F - 103F average for over a month now, it has rained once in that time but all my trees look great even new growth popping out.

I was out of the country when we had the hotter temps. So mine were in morning then dappled sun for precaution. But...typically I move my satsuki to morning sun during the hottest temps. Even with moss on their pots. My book even mentions moving them during the season when it's hottest. Crabapple I no longer offer full afternoon sun anytime. Because in the heat...I seen leaf burn in the past. But, I also don't have moss on the pot. All mine are back out...but seen some locations really had the heat index...and I was hoping none the worse for wear.

Heat? Ha! It's been raining for days now! Not nonstop, but still!
I'm curious which Tuesday summer will be on this year.
I hope you have time between the rain drops to treat for fungus...sounds like a fungus party could show up at your door with weather like that!

Well, I live in Brazil and the weather in the summer can be very hot; I've been worried about the pots getting too hot in the afternoon sun (they get really, really hot) and if this can be harmful for the roots.
You have answered my doubts, I will cover the pots from now on.
Thanks, @moke !

Morning sun is the hottest, just so you know. Here Satsuki do ok in it for a brief period in it - no more then three hours. They stay shaded for the entire rest of the day. Further South it is not uncommon to grow them under benches.
It does not invite fungal problems if there is good air circulation and they are trimmed/cut/groomed properly.
