Gardeners' Notes:

This tree does well in Louisville KY in zone 6. My tree is about 8 feet tall and was transplanted from a 7 gallon container to the ground about 4 years ago. It survived temperatures last winter which were sub minus 10 degrees. A Bihou Japanese Maple growing near it lost about 1/3 of its twigs. The sango kaku lost none. I just planted another one. There is nothing comparable for fall color and winter interest in a compact deciduous tree in this zone.

I have had my Sango for about 4 years (z 6) and it's about 3.5 feet tall. I got it as a seedling. I love it. It has year round interest due to the red bark. I have been growing it in a container and would love yo transplant it into the ground. Any suggestions on how to do this. .. to encourage growth? Certain soil? Pruning?

Lovely Japanese maple with different season's looks!! I live in zone 6 Toronto, Ontario and over winter in pot outdoor were just fine. Love its coral red stem in winter and foliage color change in different seasons!

A beautiful small vase-shaped tree that does well here in Boston Z6a. The young bark colors up vividly only in winter and early spring.

Spring foliage is a vivid chartreuse (yellow-green), often leaves also have a reddish edge. Leaf color turns more mid-green in summer. Leaf shape is like the species and not deeply dissected.

Fall foliage color is a good gold, but like all Japanese maples it's often hit by frost here before the fall color peaks. (Our average first frost is Oct 31, and Acer palmatum fall color usually peaks in the second week of November if first frost is late.)

At the University of Maine Orono, Z5a, no cultivar or seedling of A. palmatum was found to be hardy. The "regional" details above show only a couple of plants surviving ... read more

I live in central Indiana, zone 5b/6. I purchased one of the coral bark maples to replace a tree lost earlier last year. I was very excited about the bark- and fall-interest of the variety. It was growing quite well and seemed to be doing great. But this spring after all the snow had melted and it finally warmed everything above the snow pack had died. Speaking with a JMaple grower from central Ohio this past spring he told me that the coral barks were not solidly hardy anywhere in the midwest and advised me to not put another one back in. He said he had tried to grow them but could never get the to thrive or survive in his nursery. I dug up the remaining plant, good thing we had so much snow last winter, and have it in a pot so that I can move it to a secure protected spot for the winter,... read more

A really beautiful tree. Mine is planted in an Eastern exposure and receives direct sun until shortly after lunch.

We purchased it at my husband's insistence, even though I tried to tell him it was a terrible specimen-- it looked like someone had just chopped the top off to get it to fit into a truck. He's not a gardener, but he's cute, so he gets his way when deigns to accompany me to the nursery. Regardless, it does really well, except that I am still trying to figure out how to prune it back into shape.

It received a fairly severe haircut this spring, as my goals are to give it a more natural look while avoiding whorls that have five and six branches sprouting, and growth in the bottom 3-4 ft. The tree didn't skip a beat.

My little tree (about 5 ft) has been in my sandy-loam, nutritionally mulched and well-watered soil for 2 years now. It has lovely bark and healthy leaves. Gets morning shade and about 5 hours of warm to hot afternoon sun. My neutral rating is because it hasn't grown one inch in 2 years and neither has my Bloodgood Japanese maple. I understand slow growing but these are the first trees (I've invested in dozens of all varieties of trees) that haven't grown a whit since planting them!!

@ Oaklandguy, I bought a Sango Kaku in a 3 gallon container and it was a beautiful deep red with gorgeous green leaves. Sounds like he was trying to unload some bad trees.

Coral Bark is a beautiful tree, and my absolute favorite J. Maple followed by Osakazuki.


On Apr 15, 2011, OaklandGuy from Oakland, CA wrote:

Purchased a 15 gal one a couple of years ago. Love it. It really brightens up the yard in winter. Just watch out for leaf burn - protect it from hot, dry wind, and leech excess salt from the soil.

One question. I'm thinking of buying more. When I came across some 5 gal plants with poor color (totally grey in the trunk and barely pink at the new twigs), the grower tried to convince me that they need to grow to 15 gal size before the color intensifies. I think it's B.S. as the young twigs should have the brightest color, but I don't have experience growing one from 5 gal. Comments?

I am very happy with my Coral Bark Japanese Maple. It is growing very well. This is my second year having it and I love it!

Planted a small (~4.5 ft tall) one of these 5 years ago in partial shade (afternoon sun only) in recently (and deeply) tilled earth just north of Seattle. It exploded and has more than doubled in size. It has hit its '10 year size' in half the time. Love this tree. The bark is beautiful and the tree is very lush (gets plenty of water).

I just saw a whole lot of these growing in the Getty Museum Gardens in Los Angeles. They were bare of leaves, shrubby vase-shaped and spectacularly colored - red, orange and yellow. The garden is in full sun, but is on a mountaintop and gets ocean breezes, so that probably moderates the heat. I'd like to try them in San Jose. Any input?

Add on: Just realized they were probably not maples but were a variety of dogwoods. Oh well, they were gorgeous. Could they grow in Northern California?

I've had a small (originally 4' tall) Bloodgood Japanese Maple for two years here in Dallas and it has done very well even after a very hard freeze last winter and a very hot summer in the 100's many weeks in the summer. It is on the North of the house in mostly dappled shade during the summer.

I bought this plant from a nursery and they planted the first
in May 2009. It died. They replaced it in May 2010 and now
the leaves are completely dried up and the coral bark is turning dark gray/black. I think the heat is to intense in the summer time in Texas for these plants to survive. Possibly if they were put out in a more shaded area the chances of survival would be better.

We have had good luck with our coral bark in North Carolina. It started out in Winston-Salem, and we moved it with us to Raleigh. It moved well and will soon be in its third year in its new spot. We have good bark color in the winter. We have it planted in a partly shady to shady woodsy area.

This tree has done well since I planted it in full sun but mostly dry soil. It had grown to about 4 1/2 ft tall when a bear passing through my yard (looking for my birdfeeders) he broke it clean off at the base. I saw the tree laying there in the morning and the next day it was completely gone despite a search of my property. Was there something about this particular tree that attracted the bear? I'd like to replace it.

I live in Oklahoma. I planted a coral bark Japanese maple last fall. It was beautiful. It never lost its leaves. This spring its golden leaves were still on it. This summer the leaves started to turn brown and curl up. the existing branches with leaves never grew. The new growth is looking like weeds. I read an article that talked about a disease caused by the bacterium Xylella Fastidiosa, which clogs the plant's water-conducting tissues. It is spread by spittlebugs, leafhoppers and treehoppers. The article said there was no cure for it. I do not want to just chop it down. Please help.

Three years ago the 4 foot Coral Bark Maple caught our eye since everything looks so dead in the winter and the red bark brightened the garden. Here, adjacent to Cape Cod, it is growing magnificantly, sometimes too fast as a vase shaped 8 foot plus shrub with three main trunks and a multitude of arched pendulous branches.We like this tree full and unpruned to shade the A/C. Planted without any stakes in peat moss, cricket manure, loam, sand and super phosphate, with four inches of cedar mulch, in 5 hours of full sun the tree responded well. Winter die back of current season new growth is modest.. Today was the first signs of autumn with the beginning of its yellow leaves.

here in NE NC, mine is only if full sun in the AM, then dappled shade the rest of the day. very acid-y soil from the pines and large maples overhead. i too, trim unruly branches on top and continue to remove all lower branches to 4'. it creates the nice shaped 'canopy top' that makes them so appealing.

Planted mine last spring and the leaves scorched a little in full sun in Powell Ohio in the summer despite lots of watering. The coral bark was beautiful all winter. Now there are only a few leaves at the base of the tree and the bark has turned mottled grey brown. I'm guessing it froze, but maybe some disease?


On Jan 11, 2009, catcollins from West Friendship, MD (Zone 6b) wrote:

This is a really beautiful tree, but the jury is out on whether it is good for this area. We had two. One died in its second year for no apparent reason despite being in a sheltered position with full sun until 2pm. I suspect that it caught some type of blight - died from the bottom up. The other has been doing okay for 3 years now. Some winter dieback but this one is fully exposed to winter winds, full sun. It does tend to shoot out in strange directions and needs to be trimmed to shape. Beautiful bright foliage, excellent winter bark. Other types seem to be much more reliable and just as pretty.

Sango kaku is a very 'twiggy' vase-shaped upright japanese maple which grows quite tall but in the right place and if you were lucky enough to buy one with an outstanding red bark, can be quite a centerpiece. I personally do not like the 'twiggy' look so I remove a lot of the inner twigs and artistically shape my coral bark the way I want it to look. I also have it in a place where pieces of it hang into view in my diningroom window as you sit and eat. I posted a photo of mine so people could see it the way it can look if you personally also don't like the 'twiggy' look. This one seems to be a fast grower and available everywhere--it is not expensive. Buy an inexpensive junior-sized (not infant) one at your local hardware store that is well shaped and had the most RED to its bark.

I find all the coral bark Jm's hard to grow in northern areas my Japanese sunrise didn't make it either ..but I will say and say it LOUD and CLEAR that the Japanese sunrise is so FAR superior in every respect to the sango it is a no brainner ...I cant recomend it for my area cause of my experience but if you live in a more JM friendly area buy it before that stickin stupid insipid Sango!!!

I purchased my Coral Bark from a Japanese nursery in Washington then flew back to Tuscaloosa, Alabama (U.S.) with it and six other plants. It has been growing in Tuscaloosa since 1995. Today as I was having some pine trees removed they dropped a 40 year old pine on my Coral Bark.

There are newer varieties of Coral Bark Japanese Maples, but this is still one of the best. Often available at a good price in local nurseries, the leaves turn clear yellow in fall; cold weather turns the bark and branches bright red. Color is not quite so vivid on older wood as tree ages, but it remains a striking specimen, particularly when backlit. New leaves are a bright clear green with red margins. This is a vigorous, upright tree. Also known as 'Senkaki'.

Like most Japanese Maples, does need a partial shade location. Our hot dry California summer weather tends to crisp the leaf edges; mine has a late afternoon sun exposure and has suffered some damage.
