Timing of root pruning

UBC Maple Forum - Fri, 30/11/2018 - 04:31
Hi all, hope everyone is doing well.

I have several maples I summer grafted in July of 2017. The rootstock had very stout root systems, and I’m certain are quite rootbound at this point. What time of year would be best to undertake this task?

Thanks,
Kyle

Acer palmatum 'Yuri-hime' in Europe?

UBC Maple Forum - Thu, 29/11/2018 - 17:02
Santa (who I didn't believe in until five minutes ago!) has offered to bring me an Acer palmatum 'Yuri-hime' for Christmas, but he has told me I have to find one available in Europe. Although there seem to be plenty of suppliers in the US, I'm struggling to find one over here. I've tried my usual sources (Maillot, Esveld, Dick van der Maat), but none of them list it as available. In the UK the RHS only lists it at Packhorse Farm nursery, which is closed for winter, has no email...

Winter Care for JM rootstock/grafting

UBC Maple Forum - Tue, 27/11/2018 - 23:56
Hello, this is my first post. There is a lot of useful information on this forum and I am hoping someone can give me advice on how to store my JM rootstock for the winter. I plan on trying my hand at winter grafting. Currently they are in my hoop house which is 8' x 24' and 6' in height. It is covered with white plastic but not heated. The 300 rootstock plants are on the ground in 3" pots all pushed together. Do I need to bring them into my unheated garage? I am in Northwest Ohio,...

Please ID this maybe Maple whatchamacallit

UBC Maple Forum - Tue, 27/11/2018 - 09:31
This critter is in a graveyard I steal seeds from. It has the general presentation of a Japanese maple, but the leaves are ~6 or 8" square. Leaves are twice the size of Silver Maple, but half the size of Bigleaf. Lobes are a large caricature of Silver Maple. Leaves are presented horizontally in its high under-story location indicating it seeks light, but it grows well enough in low light. The horizontal leaves are strikingly dead flat and horizontal. The photos are from under the tree...

Acer Saccharum Monumentale Availability

UBC Maple Forum - Sat, 24/11/2018 - 06:51
Hello all. I’m looking for Monumentale or Tsukasa Silhouettes and am not sure where I can source them. I know Buchholz has them wholesale but what about for retail? I live in the Seattle area. They are beautiful trees!

Thanks for the help.

JM what is this trunk color?

UBC Maple Forum - Sat, 24/11/2018 - 00:53
Looking at my maples, I was curious to why some of mine have this sort of design, or color difference on the trunk. My younger ones all appear more green while my older ones seem to have this.

UBC Maple Forum - Wed, 21/11/2018 - 19:37
A local nursery has a maple for sale called "Dragon Lady". I love the name, and would like to add it to my collection....but I can find no information on this tree. The tag says "similar to O sakasuki". Have any of you heard of this tree? Thank you for any help.

Red Japanese Maples in Tropical Countries???

UBC Maple Forum - Sun, 18/11/2018 - 02:01
Hi,
Anyone has any experience planting Japanese Red Maples in tropical countries? I live in Malaysia where it is hot & sunny the whole year. We get a good amount of rain too.

I have previously bought a japanese red maple tree. It was around 5' high and red / burgundy at the time of purchase. Soon after planting it, it turned green. I do not know what the species was nor do i think the workers at the nursery. They only sell things at hefty prices but know nothing about them.

I went...

Acer Negundo Flamingo question

UBC Maple Forum - Sat, 17/11/2018 - 20:46
Hi everyone. A while back without doing my research I bought an Acer Negundo flamingo. I read that you can get it way down to keep it more as a shrub is this true?

Also I read that these are considered “weed” or “trash” trees.

Personally I really like the variegated leaves and if I can keep it small that way by pruning I’ll be happy .

However if I should get rid of it please let me know, I don’t want an overly massive tree in the corner it’s in, and it’s about 10 feet from the house,...

Excellent source of JM in the Toronto area

UBC Maple Forum - Tue, 13/11/2018 - 11:29
I was at "Plant World" (which is located in Etobicoke Ontario) this past weekend. I was there to look at their perennials but I was thoroughly impressed with this nursery's collection of Japanese Maples. There seemed to be a great variety of medium to large trees. I spoke with one of the owners and he claims that they stock approximately 90 different varieties. And from what I could see the specimens are of very high quality.

I will be there later this week to pick up a "Ruby Stars" and I...

Acer pentaphyllum

UBC Maple Forum - Thu, 08/11/2018 - 23:58
I was surprised by the Maple Society's tree at Hillier Gardens (q.v.) dropping its leaves so early. It made me think about Acer pentaphyllum - although a rarity I have one in my garden and it seems a late bud breaker but holds on to its leaves longer than many. My tree was a gift from
Furzey Gardens
near Southampton when the Maple Society paid a visit there a decade or more ago - the manager at the time was a Maple...

The Lollipop Tree at Hillier Gardens

The tree was sponsored by me for the Cloud Appreciation Society (of which I am a member) in 2016 when these pictures were taken.

Are hybrids early to drop leaves?

UBC Maple Forum - Wed, 07/11/2018 - 23:15
On my way back from Acer x freemanii (the Maple Society's adopted tree at Hillier Gardens, UK), where I was surprised its leaves had dropped by 6NOV2018, I chanced to see a young Acer x conspicuum 'Phoenix', 2016.0127 A in FD100 (Front Drive), and that too had dropped its leaves.

Budburst! How early Spring is connected to last Summer

UBC Maple Forum - Wed, 07/11/2018 - 18:47
I came across a very short and sweet article: Budburst
by William (Ned) Friedman, Director of the Arnold Arboretum
April 23, 2016

Budburst! » Arnold Arboretum

Not only does the article give us some clarity to discussions on what is bud break by showing pictures of Acer palmatum during budburst while providing a definition. But the article also talks about the storage of energy 7 to 8 months before budburst in mid to late...
