I know it is too late to repot now, but wouldn't it make sense to make use of their vigor now and repot after flowering?
Or would it be better for the tree to style them first after flowering, let the recover and then repot next spring?
Also because of the bud removal there is a lot of new growth already. Should I trim it back already to free up the flowers?
Or would that be stupid if I do repot in about two months?
I do believe it is better to repot in spring before they flower so they recover better without the summer heat.
Do you think that people who have show level trees and perfect flowers have a protection, like a greenhouse or even open shed to keep the buds dry and out of the wind? Given that I'm in a cold climate, mine basically start to bloom inside a building, and I don't have problems with blossom rot or wind damage.[edit]
Nevermind, I saw this is an old thread and I just typed exactly the same thing as I typed several months ago. My memory is going....
There must be special tricks in getting the flowers to be as pristine as possible. I have all my satsuki just sitting in the garden. And every year, I get some flowers that just don't look perfect because of the weather. Either rain and wind putting tons of dirt and mud on the flowers. Or them having a bad shape. Or not lasting very long because of humidity and high temperatures. Now it has been really dry and now when the first flowers are emerging, it is starting to rain.
I have two Hi No Maru Satsuki. The flowers seem to vary based on overwintering conditions. They’re both potted in pure Kanuma, get the same amount of sun/shade year to year, so the winter/spring conditions are the only variable I can figure out that influences the blooms. Mine lose the red center / throat many springs, which sucks considering I wait all year for that little “rising sun” bloom. I’ve owned them both 6-8 years and I’d say 2/3 years I get a white flower with a pinkish center and the 1/3 years I get a nice red center with a white flower. Hopefully someone can chime in with some insight.For sure, they must have. I don't know what the Japanese that show satsuki at festivals and shows do exactly, but I am sure they have a refined protocol to make sure the flowers come out best. Pretty sure that once a flower opens, you don't want water on the flowers, at all. Especially the large flower azaleas, when rain comes in halfway the flowering season, it knocks off all the spent flowers, and the petals let go, but stick to other parts of the plant and it becomes even more of a mess. Of course, hail is worst.
But just having them all open up roughly at the same time and have them all properly shaped; it already doesn't just happen on it's own. Last two years I haven't been able to take nice flower pictures because of the weather. Having an azalea without any brown spots, or holes in them, or misformed petals, that doesn't just happen by itself. For sure they spray fungicide as well. And of course an azalea has so many flowers, you can just remove the bad ones and still have nice ones left. Especially for white or very light pink variety, a tiny brown spot just ruins a perfect display.
Keeping it inside in a greenhouse and spraying fungicide must go a long way. But I don't know the details.
I've heard before that sports, especially sokojiro, simply don't appear during some years. And then of course weather could be the thing that decides if they do or don't appear. I don't know anyone fully understand the molecular biology reasons for sokojiro, and why they appear some years but not others. It must be complicated, because some cultivar have sokojiro occasionally in some flowers. And there are cultivar that have sokojiro in all flowers consistently.
Since you have two plants that are genetically identical and experience the same conditions, do they both always do the same thing? If they don't, then it must be a very stochastic/noisy biochemical process.
Secrets to nice flowers:
Get your azaleas up off the ground. While the azalea are in bud, put the pots on a bench several feet off the ground. This will get the blooms away from splashing dirt, ground dwelling insects and animals too.
Use a slug bait or molluscicide to eliminate slugs and snails. Keep on top of insect issues especially in spring before blooming.
