new maple garden -- pics and questions

UBC Maple Forum - 1 hour 2 min ago
So, I decided to rip out a bunch of overgrown euonymous bushes that abutted a fence in my front yard and plant a Japanese maple garden. I had a few questions, and thought I would also post some pictures here.

Background: zone 7b, approximately 50 square feet. medium clay soil, slightly acidic. the garden is in the shadow of a truly gargantuan poplar tree (~100 feet tall!) so the garden is basically in dappled light year round and gets no direct sun. I used bluestone as a flagstone...

Acer not leafing out

UBC Maple Forum - Sun, 16/05/2021 - 20:44
I received this plant from a nursery when I ordered a Calycanthus floridus and I suspect it could be an Acer. (The nursery asked that I wait for it to leaf out before getting back to them).

I repotted it as soon as I brought it home in mid-April. It had small buds that were shriveled and black, probably from frost. It has been a month since repotting and it still hasn't leafed out, and no buds show signs of developing. A scratch test shows the cambium is green.

Is it just very stressed?...

Acer palmatum 'Ukigumo Nishiki' or Olivia

UBC Maple Forum - Sun, 16/05/2021 - 09:48
Hi everyone, does anybody have any experience with Acer palmatum 'Ukigumo Nishiki '
I have Ukigumo and when I saw this advertised in a brocade form, I was very interested.
The trouble is I see no difference in the photos to my Ukigumo.

I have just seen that Ukigumo Nishiki is being re named 'Olivia'. Which is quite strange as there is already an Olivia.

Any thoughts or experience with this one would be greatly appreciated.

Difference between A. palmatum 'Pixie' and 'Alpine Sunrise'?

UBC Maple Forum - Sat, 15/05/2021 - 09:49
Hi, usually I know my maples without need for labels, but not always. A few years ago I bought 'Pixie' and 'Alpine sunrise' (might have been sold as 'Alpine surprise', not sure) as young grafts in the same mail order shipment. They were labelled and potted up in to the same size and type pots. Fast forward to the present day and I have repotted both in the last few weeks and neither has retained a label.

As both are red dwarf types derived from witches brooms I am not sure which witch is...

Maple cultivar by another name OR (Synonym).#27 #458

UBC Maple Forum - Thu, 13/05/2021 - 17:37
I wanted to see what the interest is on the Maples forum with regards to a thread that we can turn to, to see if a Maple cultivar we have seen and liked to add to our collection already exists but in a different name. Now I know the Maple Society has carried out some work on this and the updated Species list, but I felt as this forum is getting a very large amount of interest, then this thread might be of use.
It could also save you a lot of money !! Which is never a bad thing.
So I will...

How moist is too moist for soil? And a couple other newbie questions

UBC Maple Forum - Thu, 13/05/2021 - 07:55
Hi there,

I may have gone a little overboard for someone new to gardening and over the last few weeks purchased five small Japanese maples. They're between 14 and 36 inches tall.

Atropurpureum in a 1 gallon container from a garden center
Sango Kaku in a 1.5 gallon container from a garden center at a home improvement store
Golden Full Moon or Autumn Moon, not sure exactly, in a small container from a local nursery
and Shigarami and Aka Kawa Hime in small containers from acer1987 on eBay...

Pixie problem

UBC Maple Forum - Wed, 12/05/2021 - 19:05
Super growth on this one over the last 3 years.. now about 1.8m... lots of buds bursting but the leaves look sign of aphids and it’s sat between 2 other similar sized trees that are perfectly fine so not a frost issue.. as you can see it’s budding out all over but the leaves look like their curling up..Any ideas ?

White patches on the truck photo is sunlight bursting through

UBC Maple Forum - Wed, 12/05/2021 - 14:13
Hi to all!! I'm new on this forum, and so I'd like to introduce myself and some of my little trees. I'm in Italy, near Milan, and I grow JM the most of all as bonsai trees...more of these are pre-bonsai and have a long way ahead. Actually I have around 70 trees, around 50 are maples in every stage of growing (a big work for pruning and repotting, but this is bonsai!)

Just start with an Acer Phoenix (I've took the pictures today and was cloudy.....)

Tsuma gaki

UBC Maple Forum - Wed, 12/05/2021 - 10:56

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 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 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 will see in the photo...

Fertilizing JM in pots

UBC Maple Forum - Wed, 12/05/2021 - 06:45
I have a couple Japanese Maples most I will up pot soon and two I will root prune in fall. Should I fertilize them? They are doing well and I’ve read some feel it’s not necessary if they are thriving. I have these two fertilizers not sure the best to use, I’m trying to forget everything explained by the nurseries. thanks

Yellow on bark

My red dragon has this yellow like moss? Or growth on it - think it’s ok?

Anyone know what happened to website "Nippon no momiji"?

UBC Maple Forum - Tue, 11/05/2021 - 19:59
Hi, does anybody know what became of the Japanese language maple website I knew as "Nippon no momiji"? It has disappeared from its original url and I can't seem to find it with google. Despite being difficult to navigate as the buttons didn't often translate when converted to English, it was my favourite online JM resource and had great spring/summer/autumn ID shots, interesting descriptions and also culture and propogation info. (Better than Yano's website). It used to be linked in the...

Same or different?

UBC Maple Forum - Tue, 11/05/2021 - 18:42
Good afternoon everyone.

I thought I’d do a little test today regarding similar/same cultivars.

The first group are the Aka/Beni Shigitatsu Sawa’s. As they have developed over the last couple of weeks I have noticed a very subtle green in the leaves of the Aka’s, and a very subtle red in the Beni’s. I don’t know whether the pics really pic up the differences but here they are any way.

The first 4 are Aka, second 4 are Beni.

A few maples from "L'Arboretum des Barres"

UBC Maple Forum - Tue, 11/05/2021 - 18:08
"L'Arboretum des Barres" is said to be one of the "greatest Arboretums in Europe". It is certainly one of the most interseting in France and has a collection of maples.

I went there last Saturday, but I didn't take all the photos I wanted, and because it was so sunny, the contrast between light and shade didn't help, not to mention gusts of wind when trying to take close-ups.

But here are a few specimens :

acer palmatum katsura hime

View attachment 208434 fantastic tree, always changing - 6 years now from a 2" tall starter. first to break bud (with green cascade), last to turn in the fall. This gets 2 hours of sun directly overhead in at peak summer, the rest of the day, and year, it's shaded.

Root pruning made easy?

UBC Maple Forum - Tue, 11/05/2021 - 07:22
Hi everyone, I have a few JM’s to repot and will need to root prune over the years. Wondering if it’s a good idea to use a plastic or metal pot liner (nursery pot) or what I’ve recently seen a “grow bag” to line a decorative pot so that it may be easier to remove the tree from the pot and root prune? Some of my JM have clay decorative pots and the trees stand roughly 5-6’ so pruning can be heavy work considering I’m only 5’2”. Does anyone have any thoughts or experience with the “grow bags”?

Keeping acer small in pot

UBC Maple Forum - Mon, 10/05/2021 - 16:20

I'm dreaming of growing an acer (or two) on my balcony. The balcony is northfacing and shady. I'd like a cultivar with fresh green leaves for that zen forest atmosphere, that has a beautiful upright form, and gets up to 2-2.5m in height (similar width is fine).

After much research, the cultivars I'd most like to try are Seiryu, Koto No Ito, and Kamagata, in that order. Seiryu is almost my dream cultivar, but I worry it will get too big (Baumschule Nielsen says 4-5m for "very old"...

Help with plant I.D please

UBC Maple Forum - Mon, 10/05/2021 - 15:10
Hi all

This was sent to me as an Acer palmatum Elmwood. Obviously it’s not an Elmwood, but it is interesting and I’d love to know what it is. Does anyone recognise the look of it?

The oranges and rusty colours are much much vivid I really life.

Thanks to anyone who can take the time to have a look at this for me.



Help caring for Acer Japonicum Aconitifolium

UBC Maple Forum - Sat, 08/05/2021 - 07:42
Hi there, I am new to maples and am seeking help for one of my trees that has been doing great until recently. I purchased this tree who I have tagged my “rescue tree” Because it screamed at me to take it home from the nursery and I found it to be truly stunning. See details of its coming home.
MAY 2020: The Acer Japonicum came very pot bound, dry and some leaves had died but it had all that when I brought it home, it was still providing new growth and is gorgeous. I believe it is...
