what a beautiful, graceful acer!
Wow, Beautiful Upload friend. keep it up. Thank you for sharing this to us. Greetings from Korea
thanks for watching!
As ceramic pots are heavy to move, and plastic pots don’t look very appealing, I normally pot up my shrubs in plastic pots for convenience, but place that pot into a larger ceramic pot. So, if I need to repot, it’s just a matter of lifting it out of the heavy ceramic pot, tidying up the tree and placing it back in the ceramic pot. It works for me. Your trees are beautiful. I have three small Acers which I haven’t yet potted up. We get high winds where we live in NZ, so I’ll have to keep them close to the house.
Yes, that is a great way to showcase your tree while keeping it in the plastic pot.
We just traveled to NZ during the month of March. Just stayed on the north island in our small rented campervan. You live in one of the most beautiful countries on the planet. We did notice japanese maples in several of the larger cemeteries that we visited / walked thru. New Plymouth had more japanese maples then most other cities that we visited. Also traveled ' the forgotten highway", incredible views and definitely two hands on the steering wheel at all times!
@@maplesandmusic Thanks for replying. We haven’t travelled to New Plymouth or even some other cities. We live in the Far North, and it’s beautiful here too. Sadly, NZ didn’t have the usual gorgeous summer this year. We got the odd sunny day, but mostly stormy weather and rain. Yes, some highways in NZ are never straight. Too many bends and sheer drops along the way. It’s like being on a roller coaster for most of the journey. I’m glad you enjoyed your stay in NZ.
I started growing JM's from cuttings and now have 12 which survived. My Dad also gave me a Sycamore Maple sapling back in 2000 which we potted up and it has grown well. By 2016 it was about 12 feet tall. This May, I pruned it down to 2 feet leaving a side branch and it has responded very well with 5 new branches and many leaves and is 4 feet tall now in a large pot. I even have it appear in some of my YT videos as it's been around for so long :)
Do you have a guide to selecting the best container for a Japanese Maple based perhaps a trunk diameter or tree height? I have enjoyed watching your videos. Thanks! Also, container size is usually given in diameter but doesn’t suggest recommended depth.
Hi Daniel
I do have a video on my container recommendations:

Hopefully that will help you out
Careful with black pots. Black pots get really hot in direct sun.
Generally a black pot is fine, the regular watering is most important in hot sunny weather.
Hello good sir, I planted my 1 gallon japanese maple tree's into a 7 gallon pouches in hopes of growing them bigger in a relatively short period of time. I have been keeping an eye out on their water levels and sun exposure. I would love to hear your thoughts about this and would you say that there's negatives of not growing them step by step? Thank you so much for making all these informative and honest videos, hope all is well on your end :).
Hello Laertes, The maples will actually not grow faster by putting them into a large 7 gallon pot from a one gallon pot. The root system is very shallow and fibrous and it likes to be in a compact setting. By going into a large pot your tree will develope long, leggy roots which don't really lend themselves well to supporting good nutrition up the root stock. I would suggest that in the fall once the trees are dormant, remove them from the 7 gallon and go into a 2 gallon pot. A 2 gallon pot will give you a couple of years before repotting into a 5 gallon which would then give you 2-3 years additional growth before moving to a 7 gallon.
Japanese maples are SLOW growing trees, let them mature naturally rather then trying to force the growth. I hope this helps you out, Otto
@@maplesandmusic Ahh! Your explanation was just what I was looking for. I'm glad I asked cause I was gonna repot my next maple batch the same way. I greatly appreciate the help!
@@Amaterasu272727 Glad I could help you out
The other danger of 'over potting' maples is that an excess of soil in a container is going to hold loads of moisture when wet, and not drain as well as either open ground or a smaller pot with more roots to take up the water. Maples hate being sat in boggy soil so you're more likely to end up creating health issues for the root system :)
Could possibly be made into a nice bonsai
Hi Otto. Just curious which slow release fertilizer you use on your JM? I’m assuming you fertilize just once a year in Spring? Also would love to see more content. Maybe next time can share which maples love shade vs Sun. TY!
We use an osmocote 16-10-10, six month slow release. One application in early April and that’s it for the year. Approximately 1 tablespoon for smaller containers and 1 1/2 tablespoons for the large ones.
I have just updated an existing video and re-released it showing which cultivators like sun / shade and those that are suitable in both locations.
Hi. I live in Australia. I bought a potted Japanese maple Acer palmatum 'Shaina'. It was so healthy and beautiful. It started to change. It has been stressed for couple of months now, started to loose leaves and now it only has couple of leaves. I don't know what to do to bring it back. Should I transplant it, should I prune it. It's winter time over here. Any advice please?
Hi Katia, Don't forget, your tree will loose all of its leaves in the fall as it is in its dormant period now. That is a natural process. Your new growth will come in early spring. If you want to transplant it? now is the time while it is dormant. Pruning is best to be done in very early spring before the new foilage appears. I don't think you have anything to worry about.
and BTW, the Shaina is a beautiful cultivator, good choice!
@@maplesandmusic thank you for your reply. It is such a beautiful tree, when I saw it I fell in love with it. It is planted in a pot. It has a long trunk, it's shape is so nice and the leaves are dark red. Stunning!
@@katianasr9019 If you get a chance to view our "japanese maples, unusual varieties and colors" video, I have our shaina on display as well. It is approx 25 years old now and under 3' in height. I have done selective pruning on it and it is naturally a dwarf specimen
Where can I find these container? Thanks for sharing
These particular containers (made from recycled tires), I found at our local home depot in Chilliwack BC. So I assume all home depot's thru out Canada should be carrying them, hope that helps you out
Hi I just bought an acer palamatum fire glow Japanese maple and it’s currently in those plastic 2 gallon pots. I have no gardening experience whatsoever. Do I need to do anything to it other than watering it right now ? Should it be repotted into a larger pot or a pot of Same size but different material? It’s only about 2-3 feet tall right now
Hi Joe, At this time of year when it is actively growing keep it in the existing pot right now. Remember, regular watering every morning unless it is exposed to the outdoors and gets the rain when it falls.To test if it is ready to go into a larger pot , it should just lift right out of the pot with all the roots intact. If you do try to lift it and it feels like it is going to break up (soil) then no need to re pot at all. If you want to put it into a nicer looking pot for the summer, just place the whole plastic pot into a slightly larger container and then top dress with bark mulch. make sure your container has good drain holes. Fireglow is a beautiful choice!
@@maplesandmusic thanks for the reply Otto ! Actually it’s only in a 1 gallon pot at the moment. It’s only about 3 feet high. Should it be up potted into a 3 gallon container ? I’m worried I will slow it’s growth by keeping it in such a small container
@@joesimpson4655 Don't try to speed up the growth as that is the worst thing to do. Japanese maples are slow grower, let tehm grow at their own pace. The roots are tight and fibrous so your one gallon pot should be just fine for now. Do your re potting when you can just pull it out as a solid plug. Don't pull at the roots or loosen any of them. Just drop it into your larger pot ( see my re potting video)
@@maplesandmusic hi I noticed that my young Japanese maple has a lot of tiny holes on most of the leaves and that some leaves have yellow spots. What could this be caused from ?
@@joesimpson4655 Hard to say what the cause is without seeing the tree in person. It could be the result of aphids that have eaten the young foilage.
Also when it comes to watering, ONLY water the base of the plant, not the leaves during hot and sunny weather. The sun can burn the leaves when they are magnified by the water drops. And remember, when in a pot, water every morning during hot dry periods
what color does it have in autumn?
In the fall the viridis turns into a golden yellow color. I will be creating a video this fall showing the same trees with their fall colors
What a beautiful tree, how old is that ? Thanks
that is an acer palmatum "viridis" which would now be approx 10 years old. It has been container grown since day one
I live in Canada i have two maple tree that i both them this year and i plant them in containers. Because is my first time planning a tree in a containers i like to know should i live them outside and what protection i can give them thru the winter months should i water them till the snow comes down i know they will go dormant i really worried about them because the winter here is very cold thank you 😊
Hi Lela
We live in Chilliwack BC and we can get some cold weather, upwards of -20C with cold arctic outflow winds for a few weeks in the winter. All of our larger containers stay outside year round. Even our smaller containers do fine. We always top them off with bark mulch, approx 3"-4" just to protect them a little more and that is mostly from the cold winds. Acer palmatum root stock is very hardy and can handle the cold weather. You can also set your container near the south side of a wall to give them that bit of extra protection as well for the winter months. Hope that helps you out!
Otto
