The Emperor’s New Growth
If you’re seeking a fast-growing Japanese Maple tree with vivid red color, look no further than the Emperor Japanese Maple.  Known for its strength and vigorous growth, the Emperor is one of the hardiest Japanese Maple varieties available. With its mid-sized height ranging between 12-15 feet at maturity, the Emperor’s convenient stature makes it large enough to plant as a street tree or yard specimen, yet compact enough to suit most planting locations. What’s more, its upright growth is easy to maintain.  And if that’s not enough, spring leaves will arrive a few weeks later than most other Japanese Maples. That means spring frost damage won’t be a concern with the Emperor.
When it comes to Holding Color, all others Bow to the Emperor
If you’re a glutton for bright red Japanese Maple color, the Emperor will satisfy beyond your expectations.  Perhaps that’s why many enthusiast refer to it as the “Red Emperor”.  In the spring, leaves will flood your tree with heavy purple hues, followed by incredible crimson reds in the fall.  The foliage’s thin texture allows light to penetrate, giving the rich, red autumn leaves their brilliant color.  The best part is--unlike other varieties--the Emperor maintains its gorgeous color the whole season long.  

Don’t miss out on this show of color.  Order your Emperor Japanese Maple today.

It's Easy to Plant your Emperor Japanese Maple

Step 1 - Dig Your Hole

Select a site with full to partial sun and moist or well drained soil for your Emperor Japanese Maple.

First, dig each hole so that it is just shallower than the root ball and at least twice the width.

Then loosen the soil in the planting hole so the roots can easily break through.

Use your shovel or try dragging the points of a pitch fork along the sides and bottom of the hole.

Step 2 - Place Your Plant

Next, separate the roots of your Emperor Japanese Maple gently with your fingers and position them downward in the hole.

The top of the root flare, where the roots end and the trunk begins, should be about an inch above the surrounding soil.

Then make sure the plant is exactly vertical in the hole.

To make it just right, use a level.

Step 3 - Backfill Your Hole

As you backfill the hole, apply water to remove air pockets.

Remove debris like stones and grass and completely break up any dirt clumps.

Water your Emperor Japanese Maple again after the transplant is complete.

To help retain some of that moisture, it's recommended that you place mulch around each plant to a depth of 2"-3" up to but not touching the trunk. Organic mulches such as wood chips also help to better soil structure as they decompose.

So far so good!
We ordered our Emperor Japanese Maple this past fall, so I can't really review how the tree is growing since it has only been a few months, and it's winter here in Massachusetts.
But... I can say that ordering this tree through Fast-Growing Trees was simple and quick. We will definitely order more trees/bushes from them if we ever need to purchase more.

Just received and planted a Japanese Empress Red Maple. There is a white moldy substance on most of the leaves -- is this normal? Is there anything I should do for it?

P recently purchased a Emperor Japanese Maple and the leaves appear to have a white mildew on them. Is this normal? If not, how do I treat it?
Donna U on Oct 18, 2014
Best Answer: Hi Donna,
My Emperor Japanese Maple has not produced this mildew, but I have ivy on the side of my garage (ivy came with house) that started growing powder mildew for the first time. I think it has something to do with moisture. If I were you, I would buy a fungicide. I think a couple of treatments should do the trick. Good luck!

I bought a Japanese maple tree and was marked as red japanese maple. WHen I bought the plant, the tree had green leaves. now, some of the leaves have turned to red. Will th whole tree change to red?
Carmel S on Sep 1, 2014
Best Answer: Yes all of the leaves will turn red. Sometimes when the foliage gets too hot on this tree then the leaves can turn green. You should have all red leaves by the early Fall.

Will my Trees and Shrubs Look Like the Photographs?

Most trees and plants on the website are pictured in their mature form. Depending on the product and growth rate, mature development can take years for your plant to resemble the photos.

Picture the last time you took a walk in the woods. The young trees were not miniature bonsai versions of mature trees. Instead they were naturally thin and lanky. Young trees are programmed to race toward the light, before the competing vegetation crowds them out. Once established at 10 feet or more, they start developing a wide canopy and shedding lower limbs.

Bare Root trees are shipped without dirt or any green foliage showing. Some customers who have never planted bare root before, think that they received a "dead stick" with roots. These dormant trees are basically sleeping over the winter as most trees do. Because of their hibernation-like stage, this is a great way to transplant these trees. Since a bare root tree lacks foliage, they need very little moisture.

Most Trees and Shrubs are Pruned Before Shipping... at No Cost to You

Pruning makes plants appear to be less-full than the ones you may have seen at your local big box garden center. A retailer's goal is to have plants look their best while sitting in the store. Our goal is to have them look the best after you plant them.

Pruned trees and shrubs not only travel better, but become established much quicker. So rather than supporting extra foliage, they put their energy into sending out deep roots. Once that happens, your plants become hardier and quickly explode with new top growth. Above the ground, pruning helps your plants develop a more attractive form.
