Bihou Japanese Maple




You’ll Love this Maple for a Different Reason with Every Season!

Bihou brings the WOW Factor to Your Yard in Winter
The Bihou Japanese Maple’s bark glows a soft golden yellow year round. This plant especially stands out and grabs everyone’s attention in winter. When everything else dies and turns gray, your Bihou will remain vibrant and beautiful as the yellow bark and salmon-colored newly forming branches brighten up your space.

Don’t be surprised if drivers put on brakes in front of your house to check out this alluring tree.

Pretty in Every Season
The golden glow is enough for spectators to go gaga over your Bihou maple tree. But the tree always has showy leaves too. Shaped like a hand with outstretched fingers, these leaves change colors with the seasons. In spring and summer, the leaves are chartreuse lined with red edges. In fall, they turn a bright yellow-orange.

100 Years Strong, Outlasts the Test of Time
This golden-bark Japanese maple can withstand the test of time. Maples have been known to live a century and this one’s no different. Take care of this tree and it will continue to be a focal point in your yard for the rest of your life.

Low Maintenance
Luckily, you won’t have to worry about spending a lot of time caring for your Bihou. It just has basic needs: well-drained soil and regular watering.

In the south, you should plant it where it will receive morning sun and afternoon shade. In the north, it can handle full sun because it doesn’t get as hot.

Bihou can withstand shaded areas with ease.  When your older trees grow tall and block sunlight in certain areas of your yard, you can still plant this tree. Add a lot of color to your space that would otherwise be drab or shadowed.

Make a Statement Anywhere You Want It
As a member of the Coral Bark Japanese Maple family, Bihou is a beautiful addition to your garden no matter where it’s placed. You’ll appreciate its versatility.

Keep trim and place it in a planter at the entrance to your home or on your back deck. Let it stand alone in the middle of your yard to shine as a centerpiece for artistic display.

Border the woodlands at the back of your property. Plant with other colorful maples along the sides of your driveway or as a hedge between you and your neighbors.

Spice up landscaped beds by adding this vase-shaped upright tree.

No matter how you flaunt it, this gorgeous Bihou Maple will add a special touch to your yard.

Planting & Care

Seasonal Information

Bihou is a variety of Japanese Maple (palmatum type) with an upright habit.  It’s suggested zones include warmer end of zone 5 up to zone 9.  All Japanese Maples can be sensitive to hot and dry conditions; especially in the southern most regions.


In northern areas, Japanese Maple can be grown in full sun.  As you move south to warmer climates, provide some partial shade (particularly in the afternoon), or choose sites with primarily morning sun.  Bihou is a somewhat slow grower, reaching about 7’ tall and 3’ wide after 10 years.

Soil Preferences

Prefers slightly acidic soil (5.5-6.5).  Provide a well-drained medium, but one that can stay moist, so ensure plenty of organic matter.  Sandy loams work well.  Mulching is recommended to retain soil moisture and keep the roots cool but no deeper than 2” and keep mulches away from the trunk.  Use only mature composts, and avoid fresh animal manures as they will be higher in available nitrogen which is injurious to its fibrous roots.

Planting – General

Loosen the roots around the ball or if they’re bound in the container, before planting.  If necessary, use a knife or shears to loosen.

Whether planting in containers or outdoors, allow room for the root flare to end up slightly above the finished soil level after planting and settling of the soil.

When mulching around the tree, do not apply more than 2” of mulch so as to not smother the surface roots; and keep mulch away from the trunk.

Water your tree every day while waiting to plant it into the garden or into a new container.  Keeping the roots moist is very important at this time.

Always move the plant by the container or the ball and not the trunk so as to prevent root damage.


Planting – Pots/Containers

Select a container that has several holes in the bottom for drainage. If your tree is being planted indoors and your container does not have drain holes you’ll need to make sure to watch the amount of water you use so that your tree does not drown.   Size the container to facilitate the root area once you loosen them from the ball or container and give the roots enough space to establish themselves.  Choose a light potting mix that allows for good flow of water, but enough weight to it to anchor the plant.

Make sure that the root flare is above the soil surface in the pot after planting.  Keep this in mind when selecting container size.

Municipal water supplies, hard water, and water from arid regions tend to be higher in pH.  Using an azalea-type (slightly acidic) potting soil mix is advised to offset the potential for your water source to raise the pH out of the desirable range in containers.

Planting — Garden

The hole you dig should be at least twice the width of the root ball or container, but no deeper.  Dig to a depth so that you have firm, solid ground under the tree, but allow the root flare to end up slightly above the finished soil surface.  Allow for settling if the bottom of the hole is less than solid.   Amend the soil you dig as recommended above.  If the soil is well drained, you can add compost, azalea-type potting soil, or mulch at a ratio of 1 part amendment to 3 parts of the soil you dug out.

If planting into clayey soils, be more conscientious of the need for good drainage.  Make the hole bigger, add some sand to the mix, etc. so your tree will grow into soil that is most desirable.

After the hole has been prepared, place the tree in the planting hole. If the tree arrives as a burlap ball, feel the top of the root ball and be sure the root flare is slightly above ground while ensuring the firm footing below.  As you fill the soil with your mix, water well as you go to remove air space.

Water thoroughly after planting.

It is best to stake your tree to keep it from tipping or blowing over.  Keep staked for a year.   Avoid pulling the plant by its top when planting as it may tear the roots (if in a burlap ball) or create too much air space if in soil.


Be careful not to allow the tree to dry out.  During summer/dry weather, water deeply once or twice a week, slowly soaking the area around the plant to a depth of 4″. Do not over water. If the soil is wet, do not add water.  Avoid waterlogged situations, as Japanese Maples do not like ‘wet feet’.


Japanese Maples are not heavy feeders, so if you manage and maintain your organic matter, they won’t need any additional fertilizer.  If you do fertilize, use a slow release or organic-based source.

If you want to fertilize mature maples because the soil may be depleted, do so in the spring, but never allow chemical fertilizers to come in contact with plant foliage or the young roots near the surface.  Don’t fertilize into summer or in the fall.

Japanese Maples are very sensitive to nitrogen sources from ammonium nitrate.  Urea forms raise the pH which is not desirable either.  Ammonium sulfate is probably best.  Rose food, fish emulsion, and Miracid R are good choices, and ratios of 1-2-1 or 1-2-2 would be advisable.

Weed Control

Weeds shouldn’t be a concern, especially if you keep a mulch layer around the tree.

Pests and Diseases

Japanese Maples don’t have very many serious insect or disease problems; especially if you follow the soil and watering recommendations above.  Aphids, scale, borers, and mites may present a problem in certain years, but Japanese Maples can tolerate these fairly well.  Foliage tends to leaf out early in spring and can be subject to damage from late spring frosts, so don’t confuse this with insect or disease problems.

Pruning, Propogation

Bihou Japanese Maples are fairly low maintenance.  Always prune away dead, broken, or wayward branches; and never prune in the spring or summer or they will bleed.  In general, the Bihou Japapanese Maple won’t need pruning of growth other than the occasional ‘wayward’ branch.

Root pruning in containers:  This Japanese Maple may require some root pruning, particularly mature trees in containers.  If root pruning, roots should be pruned in the early spring prior to the emergence of new leaves.  This is also a good time to repot to larger containers if the roots are binding against the walls or through the drain holes of the pot.  It is important to cut roots that are becoming large and woody.  Root pruning is important to the overall health of older maples that have reached their optimum size and should be done every two to four years. After root pruning you may replace your maple in the same pot.
