    Here's my little guy.

    How much sun does Mikawa yatsubusa like? I just planted mine and it only gets 2-3 hours of mid-day sun but I think it's already showing signs of leaf burn in May. It has me a little worried because I really like it and thought this was the perfect spot but now I'm debating if I should move it or if it just needs a little more time to get established. Let me know what you think. Thanks!

    I have a MY in a bonsai pot, it's at least 10 years old, and it receives at least 2-3 hours of direct scorching Oregon sunshine each day with lots of filtered light the rest of the time. It's never experienced leaf burn and seems to be a very happy tree. My other MY, however, is about 5' tall, planted in the ground, and is always in bright filtered light with very little direct sun, and it sometimes shows browning on the tips because it's in a breezier area. Might your plant be in an area where wind is a problem?

    I don't think wind should be a problem, it's surounded by wild oak forest. I think it must be either stress from the transplant or too much water. When I planted it I gave it plenty of water and then it rained for 3 days. The soil has a lot of clay so I'm just hoping it's not drowning. It's been a couple weeks since it's rained but if I put my finger down an inch or two, the soil still feels moist. Here is a picture of whats happening to the leaves.

    No, this isn't leaf burn: something else is going on here. I don't like the splotches on the leaves nor the way the leaves are coming off the petiole. Also it appears that the exposed stem is black, and none of this is what you want. Do you have an agricultural extension plant clinic nearby? If not, what I would do in your situation is dig it up, check the roots for health, create a larger space in your clay soil wherein you put really good soil, check the plant thoroughly for insects, replant, and make sure you get good drainage for it. It doesn't look well to me, and I'm sorry for that. But I'm not sure from your photo what the pathogen is.

    The pictures with the greenish red and the orangish red were taken only a few days apart. My MY is always one of the latest to change color.

    My Mikawa Yatsubusa I got from Diana at Topiary Gardens. It's my first potted JM.

    I don't have any worthwhile photos to add- my M.Y. was viciously trimmed by rabbits over the winter and is just now fully leafed out. I just wanted to add that M.Y. has such a lovely, perfect green color. In my collection not many JMs achieve that perfect, true green. No overtones of red, no green-yellows, just green. Every time I see it in the garden I stop and soak it in, then start off with a smile. What a marvelous little tree.

    My second Mikawa Yatsubusa that is quite a bit larger than the one above. I love this cultivar.

    I just had a M.Y. shipped to me this spring. I am loving this little tree. They all have such marvelous form and nice color.

    Here is a picture of Spring seeds. First time our tree had any seeds in my 6 years with this tree. The tree was about ten years old when it was acquired. 2nd photo is the tree with seeds. 3rd photo is a nine year old tree grown as bonsai for the past 6 years.

    My little Acer palmatum ' Mikawa Yatsubusa ' is showing some lovely new growth this year. Only it's second year in the ground.

    27th July 2020 and this is my Mikawa Yatsubusa being trained. They don't become beautiful specimens overnight. It takes many many years to get them into the shape you want for your garden. And sometimes it never happens. But the trying is what gardening is all about.

    This is the 10th August 2020 and still in the heatwave. This is my continuing diary of my maples throughout the Summer as requested.
    Having a difficult time in this heat as can be seen. But as it has been extreme for this part of the world, I'm not too disappointed.

    21st August 2020, two named Summer storms are going to hit later today with winds of 50 mph plus, so I thought it better to take photos early.
    All have picked up this last week due to cooler conditions and long awaited rain. The colours are changing !!!!
    Hasn't made much if any new growth this year, then all of a sudden nearing the end of August off it goes. Such a weired year!!

    25th August 2020, the calm before storm Francis arrives. Thought I would show the other side of my Mikawa Yatsabusa and the spurt of new and strange new growth. Might tag this and remove in the Spring. !!!?

    Well it's the last day of August 2020 and as we have had a lot of rain and cooler weather here in England over the past two weeks, all my maples are doing well for the time of year.
    Yes new growth and it's September tomorrow!!!

    7th September 2020 and in Southern England it is getting warmer once again. So surprised to see my maples with such dry leaves this morning. But this year is so very different for so many reasons!!?
    A week on and the new growth on my Mikawa Yatsabusa has turned green very quickly, my fingers are crossed for no early frosts this Autumn.
