Appropriate Japanese maple cultivars for Zone 5a.

UBC Maple Forum - Thu, 14/06/2018 - 18:50
My friend and fellow Japanese maple enthusiast Elisabeth Witt has been encouraging me to post information about growing them in Zone 5. The following is based on my own experience and is not purported to be scientific fact. My opinion is that the zone information on some cultivars is not entirely accurate. I have a collection of 540 different cultivars and well over 600 trees, most of them thriving, but after years of replacing certain cultivars after winter dieback I’ve come to the...

Hi,

A bonsai friend needs to get rid of some of his trees for lack of space: we tend to buy, sow, or collect almost anything "just to try", but it can become too much.

So he gave me an Acer triflorum, not so good for bonsai, but it will fit in nicely in my jungle of potted maples.

And this one too, but he couldn't tell me what it was. It's not grafted, the leaves are rather small (5-6 cm), the new ones deep red, older ones dark green - the size of the leaves might not be really relevant...

Summer Foliage

UBC Maple Forum - Sun, 10/06/2018 - 18:28
We always have a Spring thread, and again one in fall. How about a thread with pictures of peoples maples, showing the flush of new growth, or the typical summer leaves?

I'll kick it off: new growth on 'Simon Louis Freres', 'Mirte' foliage, Paper Bark Maple in summer, 'Candy Ice'. new growth on 'Nizetii', 'Gold Coin', Henry's Maple, 'Kinran', selected seedling, 'Variegatum'.

Now I know things are never quite perfect in the summer, there's insect or sun damage, they could always look...

Bark time!

UBC Maple Forum - Sat, 09/06/2018 - 05:19
Winter is the time when the bark of maples deserves your attention.
I have thought that putting the pics together will allow a better observation of differences (if there are!).
I’ll start with a selection of snakebarks. When you place the cursor on any picture you will see the name
Enjoy!

Suggestions for container Japanese maples?

UBC Maple Forum - Thu, 07/06/2018 - 23:29
Hi everyone,

Lately for my Japanese maples I have been using only Ocean forest Potting soil, with Scott’s colored mulch on top.

I was hoping for suggestions to further the health of my maples.

I live in California zone 7b, some high winds at times, very dry, and hot during the summer. Cools down at night and mornings can be pretty cool.

In this type of environment what will help hold moisture, but won’t dry up? I seem to do ok watering every 3-4 days currently with no issues as of yet....

Continuing the Maple Society's Open Science Initiative (OSI), we present an overview of expert propagator Dick van der Maat's course in winter grafting, from collector Laura Jones. Complete with instructions and pictures showing the techniques, Laura focuses on the experience from the point of view of a keen gardener rather than a nursery professional.

New Bloodgood

UBC Maple Forum - Sat, 02/06/2018 - 19:32
I planted this Bloodgood this week in Central Texas. It is my first Japanese Maple effort. I am considering removing the branches that are close to the ground in order to have a more "tree like" shape. I would appreciate any thoughts on whether this should be done. Thanks!

Acer disease or not ?

UBC Maple Forum - Thu, 31/05/2018 - 23:21
Hello all advice would be appreciated. I have what I believe to be an Acer "bloodgood" looks quite healthy considering I live in the North East of England. The photo I have pissed concerns me, had my plant some form of disease ??
Thanks

Acer identification

UBC Maple Forum - Wed, 30/05/2018 - 16:53
Hi there, everyone,

I’m new to the forum but just hoping for some help in identifying two acers. The first couple of pictures are of a little pinkish-red acer that my mom has had in her garden for a couple of years with no label. I think it’s either a Beni Maiko, a Beni Kosode or a Shin-deshojo. I’m hoping it’s a Beni Kosode or a Shin-deshojo so I can add it to my collection that I have started in my garden, as I already have a Beni Maiko and with limited space, I don’t want to end up with...

Just had an email from Gardening Express UK.They're advertising what they say is a new maple from the Netherlands'Cascade Gold',a cross between Ryusen&Orange dream.I'd post a link but not sure it's allowed(like a free ad for them)but you can look'em up and make up your own mind.

Two mature Acers 4-5 months after transplant

UBC Maple Forum - Tue, 29/05/2018 - 18:05
Hi, I realise there are some people with incredible knowledge and understanding of Maples here just from a quick hour of reading. I want to say that I am very much NOT very knowledgable about Maples.

I live in Sussex, UK - where the weather is mixed and unpredictable at the best of times. Our soil in this area is clay heavy, but our lawn and beds etc. have had compost worked in over the course of time.

We inherited some mature Acer speciments when we moved into our house about 10 years...

Help ID this Acer Japonicum

UBC Maple Forum - Tue, 29/05/2018 - 03:49
Hi, I bought this tree from a nursery cause I really like the large AJ leaf esp. when it started to turn its color in the falls, so gorgeous. But they missed the tag, the only thing the man in the nursery can tell me it was AJ so I have been looking up and found something closed to this called either Acer Japonicum Meigetsu and AJ Meigetsu Itaya. The leaf is quite large compared with other AJ, its full opening leaf is 5"wide & 6"long (incl. photos). The tree is in the dwarf size, it is in...

Is it A. palmatum 'Atropurpureum' and what about pruning?

UBC Maple Forum - Sun, 27/05/2018 - 20:12
I need your help to identify this attached maple. This I ordered from a nursery and on invoice
it’s identified as acer palmatum Atropurpureum. Grafting is visible 2inch. above ground level.
The nursery sent it after I described that I need a max 2.5m height and wide tree.
I hope it will fit.

On the other hand I think that with later pruning I will able to form the shape.
This tree was probably stored at very tight place, because it has only 3 branches, and even if 60 inches height, the...

I think I can squeeze in a JM

UBC Maple Forum - Thu, 24/05/2018 - 21:26
I know it is difficult to make recommendations via a forum as there are so many variables that only the poster (me) are aware of. But if you will bear with me I would still like to try.

I will very likely need a replacement for a tree standard hibiscus which after a good life is probably dead. (It can be seen at the back corner where the wood panel fence meets the chain link).

Given the tight quarters I need it to be slow growing with a height after say 10 years to be 7 or 8 feet tops. I...

Tiny mask

UBC Maple Forum - Tue, 22/05/2018 - 07:35
I use pesticides as sparingly as possible, so I sometimes have the pleasure of finding unusual insects like this tiny spider, only a few millimeters big, on a shirasawanum seedling. When I looked more closely, I saw a Japanese mask ;°)

I think it's a Diaea dorsata, of the Thomisidae family, a species native to Europe and parts of Japan but absent in the Americas.

Interesting also to see how hairy the stem of this seedling from A. shirasawanum 'Aureum' is:

Gypsy moths

UBC Maple Forum - Tue, 22/05/2018 - 02:33
Hi all!

After what seems like decades, voracious gypsy moth caterpillars have made a dramatic reappearance in my western Massachusetts zone 5b garden.

Two days ago, they confined themselves to the shirasawarums--I handpicked about 50 off just one 2.5 foot Autumn Moon. Now its leaves have gone very lax despite plenty of water.
Could this be the tree's reaction to the attack?

Today, I found the caterpillars on many of my palmatum and also on fothergilla and small leaved rhodies and...

Will the real “Osakazuki” please stand up.Discussion.

UBC Maple Forum - Sun, 20/05/2018 - 20:25
Whe I was in the horticulture trade more than thirty years ago we sold A. p. “Osakazuki” which in the leaf always looked like the photograph on the left. In recent years all I see for sale as “Osakazuki” are plants with leaves that resemble the photograph on the right.
To be fair they are both spectacular in the autumn or fall.
I have heard talk about an imposter from New Zealand but I’m sure there is someone here who can shed some light on something that has puzzled me for a while.
Thanks...

A.p. Kotobuki/Murasaki Shikibu

UBC Maple Forum - Sat, 19/05/2018 - 20:30
Hey all --

I just got a young plant labeled 'Kotobuki'. One Japanese site says that Kotobuki is the same as 'Murasaki Shikibu'.

I am not having any luck finding info on either one of these names. Has anyone here got a clue? This is a beautiful plant, variegation similar to 'Asahi Zuru' or 'Oridono Nishiki'. It's a first-year graft, but it already has heavy variegation on it. I don't have any pics right now, but I can probably get some tomorrow.

Here's a pic from the Japanese site:...
