Chitose Yama?

UBC Maple Forum - Thu, 20/05/2021 - 11:48
This is where I’ve landed on identification would you agree? With close examination the serrations are double: deep aeration followed by an intermediate shallow serration, V&G bible describe this as an attribute. Overall leaf form looks consistent.

A Japanese Maple nursery through the year

UBC Maple Forum - Tue, 18/05/2021 - 09:29
I have used Barthelemy Maples for years.
They contributed to the Plantsman diaries YouTube videos last year from episode 14 being featured most weeks and then in the continuation series this year.
Everything is covered from seed sowing to grafting.
Here’s a link to episode 14, they are featured from around 21 minutes

Japanese maple leaf color and shape

UBC Maple Forum - Mon, 17/05/2021 - 23:01
I took a lot of photo's this morning as the weather was just perfect with high clouds after a light rain.
These pics. are all just close up images of what our cultivator leaves look like in our growing area. We are zoned as 8b in the gardening world.

Spring color, missing in action

UBC Maple Forum - Mon, 17/05/2021 - 22:03
Hi Maple lovers!

I have 2 Ap Peaches and Cream and an Ap Cynthia's Crown Jewel that skip their spring finery; they are planted in poor-ish soil, are growing well enough, though somewhat lanky (sun deprivation?) but do not go pink in spring. Is it possible that their shady location causes this?

One of the Peaches gave me good spring color until I had to move it hoping to prevent leaf burn in summer. Now, straight to green and white.
Ideas very appreciated. Deb

new maple garden -- pics and questions

UBC Maple Forum - Mon, 17/05/2021 - 10:12
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 ?

Some of My Maples....

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...

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

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.
