A couple of months ago, I talked about the elements that go into making a Japanese Garden…with the idea that I would be creating one in my yard this summer.

And I have to admit one of the reasons why I want a Japanese garden is that I love Japanese maples! To tell the truth, I have quite a few of them in my garden already…the Japanese Garden will just give me an excuse to get a couple more.

Japanese Maples have a bit of a reputation for being finicky, but they’re actually really easy to grow and care for once you get the hang of it.  There are just a few things you need to know to keep them happy.

Young Japanese Maples Should Not Be Pruned

Pruning young Japanese Maples can lead to poor root development.

Even if you plan to remove some of the lower branches at some point, leave them in place for the first couple of years until the plant is stronger.

There is one exception: If you see suckers growing from the root stalk (they will have different shaped leaves than the rest of the plant), you do want to remove those. Most Japanese Maples are grafted. If you let the suckers grow, they will probably end up taking over the whole plant.

Prune Established Maples In The Summer

When your Japanese Maple gets old enough to need some shaping, it shouldn’t be pruned in the early spring.  Maple sap runs in the winter, so pruning at that time can cause the wound to ooze sap, which weakens the tree.

The best time to prune them is in July and August.

They Like A Lot Of Mulch

Japanese Maples like a lot of mulch | 10 Surprising Things About Growing Beautiful Japanese Maples | If you want to add a Japanese Maple to your landscape (or you already have one growing in your garden) but aren't sure how to care for it, these tips on fertilizing, pruning and growing in containers (among other things) are very helpful!
Japanese Maples like a lot of mulch

Japanese Maples have a shallow root system, so it gets overheated easily.  Too much sun puts the whole plant under stress and weakens it.

A 6″ thick layer of mulch makes sure this doesn’t happen. Just keep it away from the trunk of the tree to prevent it from rotting.

Japanese Maples Don’t Need Too Much Fertilizer

When you first plant a Japanese Maple, resist the urge to add fertilizer.  Too much can actually weaken the plant, cause the stems to die back and invite disease.

Once it has become established, you can add some Japanese Maple fertilizer if you are so inclined.  However, mine do really well without any fertilizer at all…the thick layer of mulch decomposes into the soil and provides enough organic material to keep the plants healthy.

They Like Shade More Than Sun

Japanese maples like shade more than sun

The ideal condition for Japanese Maples is morning sun and afternoon shade. But if you can’t give them that, they will generally do better with more shade than more sun (especially if you have really hot summers like we do in South Carolina).

Too much sun will cause the leaves to burn and can cause the roots to get too hot.

However, The Leaf Color Is Better In Some Sun

Having just said that Japanese Maples prefer the shade, this sounds a bit odd…but if you have a Japanese Maple that has red, purple or variegated leaf colors, you will see more of that color if the tree has a little more sun.

You can see this easily in established trees (like the one in the picture), where the leaves on the top (that are exposed to more sun) are red, while the ones underneath are green.

Japanese Maples Grow Well In Small Containers

  • I was gifted a Japanese maple, which had long been potted and rootbound. I took it home and planted it in my garden.

    Will it ever recover, or will it be a bonsai for the rest of its existence? If it is bonsai’d, I’ll need to move it to a more spectacular location. 🙂

    • Hi Jeremy…The Japanese maple should recover eventually, especially if you loosened up the roots before you put it in the ground. They do grow pretty slowly so it may take a couple of years before you start to see some progress.

      • For some odd reason the top 18” of my Japanese Maple died off. I have pampered the rest with screen-like materials to keep the leaves out of the soil. It is at least 5 years old now and approximately 3 ft tall. The deer were munching on it the first year so I moved it to a safer location. Any advice you may give would be very helpful . Thank you so much fir your wisdom and experience.

        • Hi Dotti…I’m not sure why the top of Japanese Maples dies off sometimes (I’ve had that happen before, too). Unfortunately, when that happens, they don’t get much taller because the main stem never comes back. I moved mine to a location where the small size works and got a new one to use in the original spot.

  • Hi Wanda, great article!! You seem very educated on the subject. Do you have a “green” education, or have you just learned throughout the years? (Here is a personal question– how did you get into blogging and how/do you get paid?) I have a green background as well, and I would like to do what you do. Any help you can provide would be greatly appreciated. Thanks!–Lisa

    • Hi Lisa…I learned my gardening skills from experience, although I have done a lot of reading and going to seminars over the years so I’ve gained a lot of knowledge that way.

      I originally started the blog as a creative outlet, but now it’s my full-time job. I make money from ads and affiliate sales. You can read more about it here: How I Make Money Blogging and How To Grow Blog Traffic. Gardening blogs do very well, especially during the growing season, so I think it’s definitely worth trying!

    • Hi Christine…You should be able to grow them. I live in SC and also have clay soil. I usually mix some potting soil in with the clay when I’m planting Japanese Maples to help with drainage. But after they get going, they seem to do fine.

        • Hi Teresa…I have not run into that problem with Japanese Maples, so I’m not really sure. There are a number of diseases that cause the bark to turn black, but they shouldn’t just appear in the summer. I have seen something like this on Rhododendrons where it was actually aphids causing the problem. They leave behind a sticky substance that can get mold growing on it (which is black). If you can scrape the black stuff off, that may be what it is. If this is the case you just need to get rid of the aphids – insecticidal soap should work.

    • I live in NC and just purchased my 1st red Japanese maple. It will get only early morning sun and late afternoon sun, is that too much sun?

      • Hi Retta…Morning and late afternoon sun should be fine. As long as it is out of the sun during the hot mid-day hours, your Japanese Maple will be quite happy 🙂

  • I have 4 Japanese maples. They are gorgeous and showstoppers. We had a hard winter and as of May 26 we have no leaves. Actually a few around the bottom of 1 tree. 2leaves yo be exact. Greenhouses have told me to still wait cause of the difficult winter. What’s your thoughts. Wisconsin winters😩

    • Hi Loretta…it isn’t sounding too promising for your Japanese Maples, but I would give them a few more weeks just in case they decide to make a comeback. I hope they do! It would be a shame to lose so many of them at one time.

    • Hi Flo…yes, I have moved Japanese Maples before and they seem to do fine. I usually do it in the spring before the leaves start to come out.

  • My rare japanese maple leaves became brown suddenly, noticed shiny small bugs. Used pesticides for it and now there is no one single leave on the branches. Repotted plant from the garden into the container.. is there any chances???

    • Hi Jurgita…I haven’t had that problem before, but it’s not sounding too hopeful. I would keep it well watered in the container and hopefully it will come back.

  • I was forced to cut my red laceleaf maple down this past spring. I did not remove the 2′ stump and lost track of time to clear the stump out. About two weeks ago I noticed red sprouts coming thru the bark around the stump. Will this little fellow come back as a dwarf? I cut it out of my garden due to its large size. It was growing up as a tree would. What should I expect And should I feed it. Should I prune it? The planting area has excellent soil and auto water daily. Zone 7.

    • Hi Bettye…it’s hard to say how it will come up. If the original tree wasn’t grafted, then it should be the same as the original. If it was grafted, it will be whatever the root stock was. It shouldn’t need much fertilizing if it’s growing in good soil, and pruning it might help to keep it smaller.

    • I have a Japanese Maple in my back yard, in the past two years I have had wilting, curling leaves on half the tree. What could be the problem. Thanks Jules

  • I have always wanted a Japanese Maple, but since I live in the frozen tundra of the north I knew that wasn’t possible. Then we relandscaped our front yard and I found a nursery out of Oregon was making Japanese/Korean cross varieties that would grow in my zone and decided to take a chance. A local nursery carried them and I found one I loved. This spring I waited with baited breath hoping it survived our winter. When the leaves budded out I did a happy dance. It’s more beautiful this summer than last. One of the lower branches has put on a lot growth and is now touching the mulch. Should I leave it, or prune it back? I told my husband he is not allowed to touch it for a few years, but I was concerned about that lower branch. Any help you can give me would be greatly appreciated.

    • That’s great that you were able to find a Japanese Maple variety that will survive in your area! It’s really up to you whether you cut the branch back. It won’t hurt the tree to have it touching the mulch (I have quite a few weeping maples that do that). But if you don’t like the look of it, you can prune it back a bit.

  • I have a two year old Japanese Maple in a pot under a patio cover. The problem is the leaves tips are turning brown. Is it to much water or not enough? Fertilizer, to much or wrong kind?
    Fis

    • Hi Fis…most of the time brown edges on Japanese Maple leaves mean it’s getting too much sun or not enough water. If you put enough fertilizer on them to burn the roots, that could probably cause the problem as well (I don’t fertilize my Japanese Maples at all so I don’t have first-hand experience with that). Some varieties are more prone to getting them than others.

  • I purchased a coral bark and Maple in April. I thought I was keeping it watered. I was trying to find the best place for it. I made sure the hole just as the directions read. I planted my tree in a mostly shade area that only gets filtered morning sun. In the top 8-10 inches the leaves turned brown. The leaves are the only part that turned brown. Do you think it will be ok?

    • Hi Charlene…if the branches are still alive, it should recover. Make sure that that the soil is well watered but not soaking wet (the roots will rot if they are too wet) and that it isn’t getting too much fertilizer (if it is planted close to the grass, it could be getting runoff from the lawn fertilizer).

  • I have a mature Japanese Maple which I inherited from the previous owner of the house. She is a Master gardener and has left me with a beautiful perennial garden, however, in my opinion, she has let the foliage of the Japanese maple get too thick.
    You cannot see the trunk or the general shape of the tree at all. I have cut back some of the small lower branches to get them off the ground, but I would like to bring more light into the interior and be able to see the trunk. Having never done this before I feel a bit intimidated. How would you suggest I approach this project.

    • Hi Nancy…You can “limb up” your Japanese Maple by completely removing some of the lower branches. I would also try trimming some of the interior branches to help open it up a bit. When I’m pruning Japanese Maples, I usually go slow and take off little bits at a time to make sure I don’t go too far. The good news is that they are very resilient so pruning won’t hurt it (but they can be a little slow to grow back if you take off too much).

  • Had a tornado May 2019, japanese maple not really injured. It did leaf out next spring, really beautiful, nice red leaves all over. It is in the east side of the house, lots of morning sun, shade after 1:00 p.m. We water it once a week when dry. A heavy cold snap came late spring and hurt our 8 foot tree. Leaves shriveled up, fell.
    some stayed on the tree toward the bottom. It has not really recovered . dried up leaves and half live looking ones here and there on the tree. Healthy leaves toward the bottom of the tree. It is now Sept. 11. Will our darling 15 year old tree recover to its once beauty? Help please. It is so pretty

    • Hi Carolann…It’s hard to tell if it will come back. I would wait until next spring to see what happens. If it doesn’t recover, you will probably need to prune off the dead branches to encourage new ones to grow.
