Hi guys,
I have obtained three separate sango kaku, each from a different local nursery around my place, and intended to plant them in the backyard. I bought these trees in winter so as to be able to clearly see the branch patterns.

They are all beautiful, but one, in particular (Tree1 in pictures) have bright lime green leaves, which me and my wife in particular are very fond of. The bark on Tree1, the "lime green" leaf sango kaku is also much brighter, almost translucent red, which...

Sango Kaku variation normal?

Hi

I have two unidentified maples. One was in the garden when we bought the house. It has a green trunk and light yellow / green leaves throughout Summer which are now turning crimson. It suffered bad leaf scorch this Summer so I am trying to find out what it is to help decide whether to try moving it.

The other is round the corner and has turned a wonderful orange / crimson and I'm hoping to identify to purchase for my garden. Sorry the picture is so poor - can take more if needed....

Japanese Maple ID

Announcing the Official Japanese Maple Cultivar Classification of the Maple Society, by Cor van Gelderen!

The large and ever increasing number of Japanese Maple cultivars can sometimes cause confusion for the consumer, who may not always know what to expect from a given plant. The Japanese Maple Classification helps manage the situation by dividing the maples into seventeen distinct groups. By referencing the group the buyer can quickly form a basic impression of the plant’s...

Official Japanese Maple Classification of the Maple Society

Hi everyone. I don’t post much just lurk, but

I now have a collection of about 20 Japanese maples, with 7 of them planted in the ground, and the rest in pots.

I however don’t own the land, just the mobile it sits on and was thinking about taking the plunge and buying a house.

Is it possible to dig my Japanese maples up and take them with me? Is there a specific time of year (like winter) or way to do this without harm or is there always a risk?

If it’s going to harm them I’m just going...

Digging up Japanese maple?

Hello,

I have a dwarf red Japanese Maple tree that is losing beginning to bare leaves and those that remain have a white powdery substance on them. I've been told it is a type of fungus or mildew. Three questions
- What may have caused this to happen?
- How do I treat it?
- How do I prevent it?

The plant is on the west side of the building in a 36" bed that is covered with pine needles. We have had an incredibly hot summer in NC (2018) and then significant rain (five to eight inches) in a...

Dwarf Japanese Maple fungus

Hi, I am interested in this Japanese Maple but I read some posts that this tree might be difficult to grow. Is this true? I would like to know if anyone is growing this tree successfully? Or would it be better to go with a different Japanese Maple like Kasagi Yama or something similar?

Thanks

I was at a nursery in Toronto and they were offering a discount of 30% on most of their nursery stock.

I picked up a potted "Ryu Sei". (I had a place for a JM as long as it would remain compact).

This specimen is probably about 4.5 feet in height.

I would think this is the definition of root bound?

And here it is now in the ground.

I am curious if others have this variety and the height of your specimen.

Would it benefit from protection this winter (I am a zone 5b Cdn)?

Hello,

'Koto no ito' is one of my favorite trees. I love the softness and texture of its leaves when viewed from my patio. The fall color is outstanding. A great all around tree with a lot of interest during the growing season and fall.

I have always been fascinated with its long leaves that hang down like the strings of a harp. A very fitting name, since 'koto no ito' translates to harp strings. Being American, I always thought of the tall narrow harp that I have come to know...

A better understanding of 'Koto no ito'

I have grown this maple for eight years now. It was sold to me as Songo kaku. It has the bright red stems on young growth as expected, but growth is much less vigorous and in the autumn/fall it turns this pale bright lemon colour unlike other Songo kaku I have seen.
Any ideas?

Hi, I planted this Japanese Maple 2 years ago. I've been making sure it gets water about once a week if it doesn't rain. The tree gets morning sun and afternoon shade. A few weeks ago I noticed curling leaves on a couple branches. Also there was a branch getting new growth which wilted during that time period. What do you think caused this?
Thanks

I wanted a snake-bark maple for a long time, now, thanks to the Maple Society seeds exchange and the respected curator of the now famous "Les Souffrettes" aceratum ;-) I have three!
A. rufinerve, A. davidii, and A. tegmentosum:

3 "snake-bark" maples

I have an Acer Japonicum Acontifolium that some call the dancing peacock.
The tips (the new growth) darkened, shriveled, and now appear to be mostly gone.

Is this just the sensitivity of the new foliage to the sun, or is there something else going on? The other parts of the plant look terrific.

It is in full sun (North Carolina).


Thanks !!

I am having an exceptionally hard time finding an Acer triflorum or seed to purchase. Does anyone know where I might have some luck?

Hey everyone.

So my father has tasked me with deciding on what tree (or two) to plant in his backyard to provide some shade on a wall that tends to get very hot in the summer and thus heat up the house. His only requirements are that it be somewhere in the 15-25' tall range and not be notorious for surface roots that may cause problems when he mows.

The area is zone 6b/7a and gets full sun. I'm looking for some neat suggestions. What Acer would you plant?

I live just east of Asheville, NC (borders 6b & 7a), depending on the map and am having a terrible time choosing a Japanese maple. I have a Mikawa Yatsabusa in my back yard and want two more maples for my front porch and another one for the back yard.

The front porch is mostly shade all day, it's under a cherry and locust tree and I love the bright color of Aureum but 20 ft tall is way too big for my yard, even planted in the yard!

I like the look of a weeping maple but most I've looked...

Choosing which one to buy

After what as been officialy the warmest summer in England since 1910 the trees are certainly begining to shut down now earlier than i have previously seen before , after a never ending few months of constant hot weather and even more watering than usual we are now begining to see some interesting colours starting to appear on numerous cultivars , even one's that are usually plain are showing signs of colouring at this early stage.

The nights are getting shorter and cooler now and the...

Fall Colours 2018

I'm trying something new out. I'm growing a few varieties of Japanese Maple seeds in a grow tent. The two that I will mention in this post are Green Japanese Maple and Sango Kaku. The tent is setup with a nice exhaust system which keeps the air cycled in the tent. A 6" fan inside the tent running on low speed which I keep high in the tent to prevent the breeze for hitting the seedlings directly. I also have an LED Grow Light which I keep at a far distance from the seedlings. The...

The leaf will not do anything else,it’s been like this for a month now.

I notice at the coast near Vancouver in the past few weeks - an increasing silver blue-gray haze on the leaves of the native "Big Leaf Maples" (the really big native ones many of have in our gardens and pastures (or out at UBC forest for example)
