Cheering ourselves up with Maples

UBC Maple Forum - Tue, 26/05/2020 - 19:00
Hi everybody, during this difficult time for everybody around the world, it would be really nice for people on this and Maple Society forums to post a Spring photo of one or more of their Maples that are starting to leaf out. I know it would cheer me up. I will attach one of mine. Its Katsura, hope you like it.

JM Orangeola Question

UBC Maple Forum - Tue, 26/05/2020 - 18:39
Hello Maple Friends,

This is my first post here, but I figured that this would be the best community to reach out too. I have an beautiful Orangeola JM that has been growing in my yard for the past 8 years. It has a sandy soil mix and in full sun, which it has been very happy since planting it 8 years ago. Last year in the spring I noticed that i was getting a lot of dying off on the top branches. I let it be to see what it would do this year. This year I had no growth at all on the...

JM Orangeola Question

Picked up an 'Aureum' very late in the season

UBC Maple Forum - Tue, 26/05/2020 - 14:26
About a month ago I was smitten with this JM, after seeing on line pictures, many on this site of many beautiful Aureum specimens (I have no JM's of any type in my garden). I had been searching nursery after nursery the past few weeks with not much success. Well I was almost resigned to starting my search again next spring (of course it would be easy at that time of the year) and then I came across one at a nursery about an hour away from my home. I picked it up last night. I...

Am I overwatering or underwatering my potted Japanese Maples?

UBC Maple Forum - Sun, 24/05/2020 - 04:57
Some leaves are falling off 5 of my potted Japanese Maples. The temperature has been in the 60's every day and I've been watering them 1-2 times a week when the potting mix feels dry. Does it sound like I'm watering them too much or not enough? Thanks

Hello.

I'm new around here, and I wanted to introduce myself briefly. My name is Monica, and I am from Mallorca, Spain. I've been growing plants since 2006, but maples since seven years.

The Mediterranean climate is a challenge for maples. Annual temperatures in my area range from 38 degrees Celsius in summer to -1.5 degrees Celsius in the coldest month of the year. In addition, the soil is clayey, so there is no choice but to grow them in pots, with mineral substrates so that the roots...

The power of JM”s to recover from disease

UBC Maple Forum - Sat, 23/05/2020 - 05:57
Die back from pathogen can be rapid and often totally kills a tree. Hopefully it’s spotted before travelling to the main trunk and can be removed or the treee compartmentalises the affected branch.
Sometimes I don’t catch the disease early enough to remove the affected limb and if in the main trunk, will cut the tree down to a stump above the graft.
Here’s some pictures showing a tree just starting to bud back, another a little further along and lastly, one that had this treatment a few...

Japanese maple potential disease identification

UBC Maple Forum - Fri, 22/05/2020 - 22:36
Can anyone help identify this marking on my 10 yr old seiryu?

I recently pruned this branch (pic attached) because it was problematic to growth, but there is another branch still on the tree with similar spotting and still showing new growth.

drooping leaves on bloodgood maple

UBC Maple Forum - Fri, 22/05/2020 - 05:45
I have a young bloodgood maple planted two years ago. It has looked very good for two years and is about 8 ft tall . I have clay soil and think the tree may have received too much water . Instead of splaying out horizontally the leaves are hanging at about a 30 degree angle and a couple of them have curled up. Is there anything I can do for it except hope that it stops raining.
thanks

Favorite places to buy young JM

UBC Maple Forum - Fri, 22/05/2020 - 03:31
Hi all! curious about everyone's favorite places online or B&M to buy young Japanese maples. I love the variety available online but have struggled to find a website that I thought was reasonable with shipping figured into price. Most of my purchases so far have been from local nurseries when they have sales but typically plants are in pretty bad shape when they go on sale (not too many nurseries in Oklahoma USA good with JM) eager to hear everyone's options! Thanks for reading

Grafted unknown young maple

UBC Maple Forum - Wed, 20/05/2020 - 21:56
I bought this little untagged acer palmatum (I think it's acer palmatum) from a neighborhood nursery that sells maples mostly from Buchholz in Oregon. It was on sale at the end of the season in October 2017. Thought maybe it was Osakazuki but the leaves are not the same as that one. The mature leaves are a little distinctive--amoenum and the lobes are kind of club shaped. Was thinking that maybe someone would recognize them. I have only 34 maples and it matches none of them and have...

Blood Maples after hard freeze

UBC Maple Forum - Wed, 20/05/2020 - 03:19
Hello everyone. I’m a new poster but I love reading the forums here. I’m hoping to get some advice on 2 red blood maples that went through a hard freeze here in Ohio about 10 days ago.

One is about 6 feet tall, the other about 8. Both have filled out beautifully over the past few years. The temperature reached around 25/26F overnight and both trees have since had more or less all the leaves die. About half the leaves have fallen now and the rest likely will fall this week due to some heavy...

Browning on some leaves on Esk Sunset

UBC Maple Forum - Tue, 19/05/2020 - 05:28
Hi, some leaves have browning on my Esk Sunset Maple. The tree gets full sun and there has been no frost. It's mainly been in the 60's every day. Only 2 warmer days recently where it was in the mid to upper 70's. This spring I removed some girdling roots near the root flare when it had buds. The tree didn't put on that much new growth this spring. Any ideas? Do you think the tree is stressed from the root loss? The tree was planted in the spring of 2018. Thanks.

I was able to make a cyanotype with more detail using a laser printer. Turns out inkjet provides the best negative for images, but I don't have an inkjet printer.

I am happy to donate any of my prints to Maple Society to use as MS saw fit.

Lollipop trees and dead branches

UBC Maple Forum - Mon, 18/05/2020 - 18:14
I thought I would start this thread after speaking to a friend online, he asked me why he has so many dead branches on his Japanese maple this Spring. He showed me via his camera phone what had happened. But to be tbh I really didn't need to see it.
Last year after a bbq at his house, I said to him that he would have problems with his Japanese maple as he has a dense canopy lollypop tree.
He obviously forgot what I said as people so often do with small talk at a bbq.
So yesterday I saw a...

Dying 14 y.o maple

UBC Maple Forum - Mon, 18/05/2020 - 12:45
Grateful to have found this forum! We have a maple in our front yard that has been on the decline for approximately 4 seasons. It stands about 20 ft. tall, and was very healthy and productive when We moved in 6 1/2 years ago, but this spring there are only buds and new growth on the bottom third with visible dead branches And no signs of life above that—-By comparison, our tree is stunted and is about 1/3 the size of neighborhood trees planted around the same time. No idea what type of maple...

Japanese Maple bark shedding question

UBC Maple Forum - Mon, 18/05/2020 - 05:24
We have a 6 year old JM in the front of our house - south facing - in southern Ontario

it has grown well since we planted it but we have noticed this spring that the bark in the main trunk is shedding a lot - the tree otherwise seems fine. I have attached some pictures to help. Does anyone have suggestions on what to do? I understand that maples do this sometimes but I’m concerned about how much has shed - thanks

Making the cut...how much to prune my sick JM?

UBC Maple Forum - Sun, 17/05/2020 - 16:37
They’re beauties! My first ever JM’s inherited in the landscaping of a home purchased a year ago. However, they’re both sick and I know they need to be pruned back. But how much?

Pictures are included. According to advice from other threads on the forum, I can confirm dead tissue and dieback on the limbs of both. The leaves on the healthy part of each are various colors from green , to dark purple and bright red. Not much is known about the soil (took a picture of that too).

On the...
