Of the three Japanese maple leaf types—red, green, or variegated—red Japanese maples are the most common and the most popular. Their colorful foliage makes them a focal point in every landscape. Of the many varieties of Japanese red maples, the compact, slow-growing cultivar ‘Red Dragon’, which was bred in New Zealand, is ideal for small yards, near a patio, or in a rock garden. It is also well suited to being grown in a container.

The Red Dragon Japanese maple is a variety with leaves that are deeply cut, feathery, and fern-like, hence the common name “laceleaf maple”. With its low height, weeping branches, and spreading habit, it looks more like a shrub than a tree.

What makes this Japanese red maple stand out is its continuous red color during the entire growing season. It starts with bright red, cherry-colored leaves in the spring that become darker over the summer and turn scarlet in the fall. After the tree has dropped its leaves, it is still an eye-catcher with its twisted trunk that becomes gnarlier as the tree matures.

Red Dragon Japanese Maple Care

The branches of a fully mature Red Dragon maple cascade to the ground giving it an eyecatching grace and another common name of laceleaf weeping maple. This can take time as most Japanese maples take 8 years or longer to reach full growth. A young Red Dragon is still a beautiful specimen plant in the garden with stunning foliage regardless of the tree’s age.

Red Dragon Japanese maple is a slow grower, so not pruning it and letting nature takes its course is part of the charm.

When planting, the roots need to be spread out to discourage the circular growth habit. Aim the roots outwards so they do not strangle themselves, which is common in many maples.

If you have a black walnut tree in your yard, you can plant a Red Dragon Japanese maple without concerns because Japanese maples are tolerant of black walnuts.

It is best to plant Red Dragon Japanese maple where it gets morning sun and afternoon shade.

A location where it is protected from the midday sun by a fence or a building is a good option. Another option is to plant it as an understory tree, so it grows in the dappled shade of a large deciduous tree with an open canopy.

The leaves of the laceleaf maples are very thin and delicate and too much hot, direct sun will scorch them.


The soil needs to be evenly moist, well-drained, and rich in organic matter. Japanese maple does best in soil that is slightly acidic. If your garden soil is alkaline (measure your pH if you are unsure), add chelated iron to the soil once a year, which you can find at garden centers.


After planting the tree, water it regularly for the first two growing seasons, until it is established.

Red Dragon Japanese maple, like all maples, has shallow roots, so, unlike other trees, their roots won’t reach deep into the soil to get water. It also means that the roots are exposed to the elements and dry out quickly. Therefore it is important to mulch around the tree to retain the moisture, and water the tree during dry spells.

Temperature and Humidity

Red Dragon Japanese maple can withstand moderate humidity, but the tree does not do well in hot weather above 90 degrees F. Hot dry wind can be especially damaging to the tender leaves and scorch them.

Similarly, in windy locations, the tree can suffer winter damage from chilly gusts, so pick a spot that offers protection.

The tree tends to leaf out early, which, in the event of a late frost, can also damage the young leaves. 


When planted in rich soil with plenty of organic matter, Red Dragon Japanese maple does not need a lot of fertilizer. If the soil needs a nutrient boost, in late winter or early spring, apply slow-release or controlled-release fertilizer pellets.

Do not use liquid fertilizer because it will make the tree grow too much foliage too fast, which is counter to its nature, and that can lead to breakage. A fertilizer high in nitrogen is not good for the same reason. 

Growing in Containers

Because Red Dragon Japanese maple is a very compact tree and grows so slowly, you can plant it in a large planter or as a bonsai. When growing it in a container, the caution about too much sun and heat applies even more. Like all container plants, it will need more frequent watering.

Common Pests and Plant Diseases

Red Dragon Japanese maple is susceptible to several diseases, such as stem canker, leaf spots, fusarium wilt, and verticillium wilt, botrytis, anthracnose, and root rot. Common pests are aphids, scales, borers, and root weevils.
