Newbie to Japanese Maples - Murasaki Kiyohime

UBC Maple Forum - Tue, 18/06/2019 - 00:25
Hello all!

Recently I have gotten interest in Japanese maples. I've been watching alot of videos and reading a ton online and finally purchased one. It was a Murasaki Kiyohime from Mendocino Maples. It came in a 1 gallon container, so I immediately moved it into a 3 gallon pot. I chose this specific species is because it's a dwarf and I want to keep it as a container tree.

I purchased a soil mix that had bark and such in there but that was it. I didn't use any fertilizer or any root...

Help with a Japanese Maple

UBC Maple Forum - Tue, 11/06/2019 - 21:05
Hello all! Super new here, first post. I recently picked up a bunch of Japanese Maples (26) and some appear to be in poor condition, many have possible sun scorch - white spots, burns on leaf edge. I am hoping someone can give insight as to how to bring this particular tree back to it’s full beauty. My husband read about Super thrive so we picked that up.

This tree has lots of bald spots, lots of dead and wilted leaves, white spots and burns that appear to be sun scorch but I could be...

New arrivals, advice please

UBC Maple Forum - Wed, 05/06/2019 - 20:16
Hi all

2 new young arrivals turned up at my door today. Very exciting. I got them from eBay at quite reasonable prices. An Ukigumo in a 3 ltr pot which I’m very happy with. I have never even seen one of these before and I wondered whether they have any special needs. I’m guessing/hoping the same kind of conditions as my other Maples will be ideal - morning sun, afternoon dappled shade and free draining soil etc? The other is a tiny tiny Beni Otake that looks like a “newborn”. Looking at how...

Borer in Maple Tree

UBC Maple Forum - Tue, 04/06/2019 - 18:13
Hi,

My wife and I live in Deep Cove, North Saanich and have just had an issue with borers in a young Japanese Emperor Maple tree that we purchased 2 years ago.

The tree was doing great and it started to leaf this year when it was hit with caterpillars that destroyed the initial flush of leaves very quickly and completely. We treated it with BTK and killed the caterpillars and were hoping that the tree would put forth another set of leaves. Unfortunately we then realized a week later that...

A. japonicum 'Oudenbosch'

UBC Maple Forum - Tue, 04/06/2019 - 16:50
Is anyone growing this? It's a nice maple but I can't figure out whether it has a weeping or upright form. Starting to think about sites for planting this fall. Esveld says 3m in 10 yrs which implies upright, but it sure seems like a weeper in the pot!

TIA for any info.

Old Maple

UBC Maple Forum - Mon, 03/06/2019 - 13:19
We have a maple that is 90-100 years old. Every year we get a bunch of maples growing in our gutter from seed. We hate to just clean them out an kill them; any place we can take them in Viginia for maple lovers to have?

Does any one know what happened to Mapletopia?

UBC Maple Forum - Sun, 02/06/2019 - 23:43
Hi every one, I use to buy trees from Mapletopia (Ryan Eggleston) but noticed he no longer sells maples on eBay. I’ve tried messaging him with no response.

Does anyone know if he changed his name or anything? Would love to buy some more from this particular person.

JM Mikawa Yatsubusa 2nd attempt

UBC Maple Forum - Sat, 01/06/2019 - 12:22
Although purchased from a quality company specialising in JMs and potting it in quality soil, my first Mikawa Yatsubusa died from Verticillium wilt in its third year with all typical symptoms : (

I wanted to give this peculiar looking variant a 2nd attempt, purchased a new tree (just eight years old and three feet high) in the second week this April, planted it in a terracotta pot with a slightly acidic well-draining soil-mix, and watered it well since (tree times per week, around 23°C...

Unique Maple???

UBC Maple Forum - Thu, 30/05/2019 - 03:12
Came across this Maple(Sugar???) at the new subdivision I am working at. The tree was obviously there before construction began 3 years ago as its around 15ft tall and in between 2 other larger trees. Is its colour any thing special?(only my 2nd year being interested in trees) Should mention it was this colour all last summer aswell. I like it regardless. Could anyone point me in the direction of good instructions for growing Maples from cuttings? Would like to see if I could grow a couple...

Potting containers and correct soil

UBC Maple Forum - Wed, 29/05/2019 - 21:43
Hi all

I know this will have been covered over the years and across various other threads. 95% of my Japanese Maples are in containers and will most likely spend the rest of their (my) life in these conditions. I believe many of you also grow your trees in containers, so there will be a wealth of knowledge on the subject. This may also result in answers for anyone else out there who may be new to this world.

1) Containers - As Japanese Maples have relatively shallow root systems, with a...

Japanese Maple dying out ?

UBC Maple Forum - Tue, 28/05/2019 - 22:57
Hi,

I currently own two japanese maples, a red one and a green one, bought around 2.5 months ago. They are currently exposed north-west. I also live in the middle of France. There's often wind so I put them behind a wall.

The state of the red one is currently worrying me. It all started with leaves sort of burning (getting grey or dried out). I started watering it a bit more, since it seemed to be either sunburn or because I wasn't giving them enough water. It seemed to alleviate the...

Guess where I went today

UBC Maple Forum - Mon, 27/05/2019 - 18:11
Hello everyone.

A spontaneous trip to Westernbirt Arboretum today. Happy days.

Here are a few of the pics I snapped. They are just taken with my iPhone so nothing special.

Can’t wait to go again in Autumn!

Damage to JM leaves

UBC Maple Forum - Sun, 26/05/2019 - 04:52
Here is a message and 2 photos from a friend who wonders what is damaging some of the leaves on her young Japanese maple. Do you think this is an insect problem or just cultural damage?

"Leaves at the ends of branches look “chewed”. At first I thought they had been battered by the recent high winds, being only the newest leaves at the ends. Now I’m wondering if an insect is involved. Otherwise, there’s new growth coming along."

A.p. 'Firecracker'

Should I buy a Firecracker?

UBC Maple Forum - Sat, 25/05/2019 - 22:51
Hi all

Tomorrow I have the opportunity to buy an A.P Firecracker. Am I right in thinking this is a red upright dissectum? I thought the Seiryu was the only upright dissectum?

It is between 3 and 5 years old I think and 3-4 ft tall. I have a Koto No Ito of a similar size. They should look good together.. Shouldn’t they?

Does anyone have experience of the Firecracker?

Thanks in advance.

Luke

Premature offering of tentatively named palmatum varieties

UBC Maple Forum - Sat, 25/05/2019 - 22:41
If you follow this link and then scroll down the page you will run into a section of summer sale "collectible" plants:

http://www.worldplants.com/specials.htm

The two offered are:

Acer palmatum 'Ed Carman'
Acer japonicum 'Shuriken'

Please don't mistake my creation of this thread as a means to start trouble or speak down about World Plants as that is not the issue. I think they offer suitable plants at very good prices. My issue is that the climate today in maples...
