    Hi,

    Does anyone have a photograph of late summer/early autumn new growth on Tsuma gaki?

    I picked this tree up yesterday, it needs some real TLC..am pretty sure it’s Tsuma gaki, I saw a Tsuma gaki at a nursery I don’t visit often a year or so ago and am pretty sure it’s the very same tree..but it’s now lost it’s tag..it was a bit of a bargain at £50 given it has a 3+ inch trunk..there is quite a bit of dieback but there are plenty of buds all over so I am hopeful..you will see in the photo some dark brown sections..but they have buds above.it looks more black in the photos but that’s just the poor photo. I’m such a sucker for trees that need TLC! Tsuma gaki loose their leaves early so that’s another indicator I guess

    Few pics of mine way back over various years , you will need to give this one plenty of shade to get the lovely spring leaf colour ,what it's known for

    Yes probably an error of judgement but let’s see how it pans out.

    It looks like bark with smut on it to me.
    Pseudomonas syrangae is a bacterial infection that kills the cambium and it is from this death that the bark appears black(-ish). Further, the bark will be 'oozy' and/or 'punky' for a while and will easily slip until the celluar fluid goes away (where ever it goes, evaporation?).

    If, as it appears, is not oozy/punky/slipping, try scrubbing it with an hydrogen peroxide solution of about 1000 ppm (like 2 tableshoons in a quart of water) and a toothbrush.

    Update on the basket case I saved from the burn pile from the nursery. Now repotted in a large oak barrel. I think its showing good prospects, give it a few years. I wasn’t even 100% sure it was TS when I picked it up!

    One of my favourite, but here I lost a first one, then the second one had what I identified as fungal infection (?) soon after spring.

    I'm still looking for the best mix, the best exposure, etc. to keep it healthy.

    One of the problems is I think that my water is very hard and I think it needs another pH, something slightly lower than 7.

    thanks Alain. One of my favourites too..your TG looks absolutely suberb..i can imagine a small specimen would make a fabulous bonsai. I spotted the tree at a small nursery I don’t often visit about 4 years ago, back then it was in superb condition, it was massive, and vibrant colour but they neglected it and had it in full sun. I will do what I can with this over the coming years. It will live in my potting area which is very sheltered and will only get sun until 11.30am..taking into account what you said I will water with rain water only. My Peaches and cream has come out with very red tips this year like TG..I will post a photo in the cheering us up thread

    As they say R, 'patience is a virtue'. Looking really good now. Well done you.

    And doesn't it look so very happy. You couldn't have it in a better position there Alain. Red fingernails with no browning. Perfect.

    Indeed, it does. So far..."No browning" : that's the problem, each year the leaves look miserable at the end of the season. Fungal attacks ? Hot temperatures ? I don't know but it's hard to keep healthy until the Autumn. It's now in almost 100% shade.

    I wanted to treat with Bordeaux mix (there's one which is colourless) or "Nordox", but it keeps on raining every day. I'll see if there's at least one day next week with 12-24 hours without rain. I will also use some fertilizer with chelated iron, etc. because when I have to water from the hose, the water is sooo hard that it causes chlorosis, which weakens the plants.

    Sequestrene sounds like a great idea, I should try it. Finally gave up on it looking good in a pot, and it's reached that annoying size, so I planted. Gets some mid-day and afternoon shade. But look how yellow.

    Has always looked the dog's dinner (but not that good) by mid-summer. I asked on FB about exposition and got the inevitable "mine's in full sun, grows like a monster!" responses...
