I know you aren't trying to make me jealous but . . . here's my Osakazuki - now being referred to as 'Osakasulky'.
Good morning Margot, don’t worry, I have many in my garden in the same state. It's a slow start here as well.
19th April 2022 and as promised tk @Xi-feng and @stg, a close up of the colours of my Osakazuki leaf a few minutes ago. As can be seen, a different area different colouring.
After a rough start with my Osakazuki, it seems to finally be in the right place for it's 2nd growing season in the ground. I had a lot of branch dieback immediately on getting the tree (fall), drought damage I assume. The 1st season was just getting itself established in the ground and find what bud sites had survived. I'm really hoping this takes off this year and in a few years really starts to shine, it's by far the only maple in my collection that needs to play catch up in branch form and health.
It looks to be in a great spot to grow large. I would worry a little though about the forked trunk. After a mid-April snow here, many trees of all types have lost significant branches.
This is certainly a concern but luckily I'm located on the floor of the Willamette Valley and snow heavy snow is something that doesn't happen here a lot. Are there any preventative measures I could take in the meantime though?
You may find this thread from the UBC Forums 10 years ago helpful. Personally, I'd be reluctant at this stage to cut back or remove one of the 2 branches. If you don't have to worry too much about heavy snow, perhaps you can protect the tree by knocking off snow if and when it becomes a threat. I have to admit that none of trees in my garden that lost branches in the recent heavy snowfall were Japanese maples. Japanese maple: two trunks or one? Hopefully someone more experienced than I am with Japanese maples can weigh in on this.
Regarding two trunks or one, IMO it is mainly personal choice. There is no right or wrong way. But obviously as @Margot suggested, if you do get heavy Winter snow, then you will have remove any from the branches. But this should not be a problem on your decking area Connor.
Thanks for everyones input, really appreciate you all so much! This forum is such a blessing. :) I have decided to stake up one of the main forks on my Osakazuki, making it more of a "upright" as opposed to flopping over the fence. I like the look already! hahaha.
29th April 2022 and my old Osakazuki that was badly damaged a couple of years back is on it's way to a good year.
21st May 2022 and my Osakazuki has transitioned to Summer colours already. It did enjoy the overnight showers.
I know I take a lot of photos of my Osakazuki, but I can't help it. From the changing colours to the leaf shape, I love everything about this tree. It also mingles beautifully with the neighbouring Ornatum, giving this awesome contrast of colours and textures in the same space:
Thought I'd add yesterday's pictures of my little Osakazuki here - lots of early colour-change this year, into some autumn colours already:
