The Crimson Queen Japanese maple tree, a variation of standard Japanese maples, is one of the prettiest of the dwarf trees. It can be a good fall foliage tree, as the maple keeps its bright-red leaves, and the cascading habit offers some winter interest.

Crimson Queen Japanese maple trees are commonly used for landscaping purposes, not only because of the beautiful leaves but also because it's smaller than most maples. The typical tree is about 10 feet tall, compared to other types of maples that can be up to 100 feet. Therefore, the Crimson Queen will fit into tighter spaces than other types of maple trees can. Additionally, Crimson Queen is one of those sought-after plants that will grow under black walnuts.

Light

The Crimson Queen Japanese maple tree is fairly forgiving when it comes to the amount of light it gets. In the northern regions, these maple trees can be grown in full sun; and in southern areas, these trees prefer part afternoon shade. If you live in a hot region, be aware that new foliage may scorch in full sun, so partial shade is a better choice for planting this type of tree.

Soil

As with light, Crimson Queen Japanese maple trees are malleable with soil. The tree grows easily in organically rich, slightly acidic soil that's kept moist but well-drained. Sandy loam soils work just fine, and Japanese maples can tolerate heavy clays. What they can't tolerate, however, are salty soils or highly alkaline soils. Add 3 to 4 inches of shredded bark around the root of the tree as mulch.

Water

Japanese maples are drought-tolerant once they have matured. However, in the beginning, they need heavy watering twice a week. If it's dry, go up to water three to four times a week until it is well-established.

Temperature and Humidity

Japanese maple trees thrive in warm climates, as long as the foliage doesn't risk sun scorch. For gardeners in climates at the northern end of its range of zones 5 to 9, perhaps the biggest problem faced in growing Japanese maple trees is potential damage from a frost or a freeze. However, the roots can withstand temperatures as low as 14 degrees Fahrenheit.

Fertilizer

Give a Japanese maple plenty of compost around the tree, as it feeds quite a bit. Keep adding the compost throughout spring and early summer to provide nutrients and moisture to the roots. If you don't have compost, use an all-purpose fertilizer, per the manufacturer's directions, around the base of the trunk in the springtime.

Types of Japanese Maples

There are several varieties of Japanese Maple trees including:

  • 'Bloodgood' (Acer palmatum atropurpureum 'Bloodgood') grows up to 20 feet tall with reddish-purple leaves.
  • 'Red Dragon' (Acer palmatum dissectum 'Red Dragon') can grow as tall as 8 feet in height and has a reddish-purple foliage that changes into a crimson red. It is a good container or patio tree.
  • 'Autumn Moon' (Acer shirasawanum 'Autumn Moon') grows up to 10 feet tall and has a yellow-orange leaves in the spring time which transforms into a bright reddish-orange in the fall.
  • 'Butterfly' (Acer palmatum 'Butterfly') grows between 7 to 12 feet in height and sports unique foliage that are green with areas of white that change to red or magenta during the fall.

Pruning

Avoid pruning a Crimson Queen Japanese maple tree when possible. If you must prune, do it in the late fall or mid-winter to avoid the bleeding that can happen in the spring and summer months.

Propagating Crimson Queen Japanese Maple Trees

You can propagate Japanese maple trees in the late spring by taking softwood stem cuttings or with semi-hardwood stem cuttings in the midsummer. Here's how:

  1. Cut a 6- to 8-inch new growth section.
  2. Plant the cutting in a rooting soil made up of equal parts peat moss, coarse sand, and perlite.
  3. Moisten with water, but don't oversaturate the soil.
  4. Place the cutting in a location that gets bright, indirect light.

Potting and Repotting

Dwarf varieties of Japanese maple trees, such as the Crimson Queen, which are less than 10 feet tall when mature can be grown in containers. If the tree grows to more than 10 feet, prune it regularly.

To grow the tree in a container: Pick a container that's no more than twice the volume of the roots and has a drainage hole. Fill it with high-quality potting soil that's free from slow-release fertilizer. Only fertilize the container-grown tree with a water-based fertilizer that's been devoted to half-strength when growth begins.

Crimson Queen Japanese maple trees grown in containers require repotting regularly. Repot the tree when the roots hit the sides and bottom of the pot—typically occurs every two years or so. When repotting, prune the large woody roots to encourage small, fibrous roots in their place.

Overwintering

To prepare your Crimson Queen Japanese maple tree for colder weather plan ahead. Do not fertilize the tree after mid-summer, and plan to water heavily in the fall to help the root system of the tree before the cold weather comes along. After soaking, spread a thick four-inch layer of mulch around the tree trunk and root area. If the trees are in their younger years, you should protect them by wrapping them in burlap.

Any trees planted in containers, bring them indoors into a garage, for example, if in areas that will get heavy frost or freezes.

Common Pests and Diseases

The Crimson Queen Japanese maple tree does have some common pests and diseases that it is susceptible to. The most common disease is a type of fungus. Canker, anthracnose, and verticillium wilt are all fungus infections that are common for this tree. Keep it pruned, the area around the tree cleaned up of dead branches and leaves, and treat the tree with a fungicide. Pests that may attack this maple tree are Japanese beetles, aphids, scale, and mites. Treat with a chemical or natural insecticide, such as Neem oil to eliminate these pests.
