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.
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. 
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.
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.
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.
This is grafted plant around 3~4 feet height in 2 gallon pot.
