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 Crimsone Queen will fit into tighter spaces than other types of maple trees. Additionally, Crimson Queen is one of those sought-after plants that will grow under black walnuts.

Watch Now: How to Grow a Crimson Queen Japanese Maple Tree
Crimson Queen Japanese Maple Tree Care
Crimson Queen Japanese maple trees are easily grown in warm or even slightly cool climates. It doesn't have any serious insect or disease problems, and the tree will showcase its bright red foliage throughout the growing season. It's smaller than other types of Japanese maple trees, growing just to around 12 feet tall with a wide spread of foliage.
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; in southernly areas, they prefer part afternoon shade. If you live in a hot region, be aware that new foliage may scorch in full sun.
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 inches of shredded bark around the root of the tree as mulch.
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.
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.
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.
Potting and Repotting
Crimson Queen Japanese maple trees can be grown in containers, but they need to be repotted regularly. Repot the tree when the roots hit the sides and bottom of the pot, which typically occurs every two years or so. When repotting, prune the large woody roots to encourage small, fibrous roots in its place.
Propagating Crimson Queen Japanese Maple Trees
You can propagate Japanese maple trees in the late spring by taking softwood stem cuttings on the midsummer with semi-hardwood stem cuttings. To do so, cut a 6- to 8-inch new growth section and plant it in a rooting soil made up of equal parts peat moss, coarse sand, and perlite. Moisten with water, but don't oversaturate the soil, and place the cutting in a location that gets bright, indirect light.
Toxicity of Japanese Maple Trees
Although Japanese maple trees are not toxic to humans, cats, or dogs, the trees—particularly wilted leaves—are toxic to horses, according to the ASPCA. Signs of toxicity include anemia, weakness, and difficulty breathing.
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 spring and summer months.
Growing in Containers
Dwarf varieties of Japanese maple trees, such as Crimson Queen, that 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 one 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.
