The Royal Crown Amur Maple (Acer ginnala 'Royal Crown') is a stunning deciduous tree that is known for its clump-forming growth habit.
- Size: The Royal Crown Amur Maple typically reaches a mature height of around 15 to 20 feet (4.5 to 6 meters) with a spread of 12 to 15 feet (3.6 to 4.5 meters). Its clump-forming growth habit creates a dense, multi-stemmed canopy.
- Sunlight: This maple tree thrives in full sun to partial shade. It prefers at least 6 hours of direct sunlight daily for optimal growth and foliage coloration.
- Soil: It adapts well to various soil types, including clay, loam, and sandy soils. However, it prefers moist, well-drained soil conditions. Ensure the soil is slightly acidic to neutral in pH.
- Watering: Adequate watering is crucial during the tree's establishment period. Once established, the Royal Crown Amur Maple is moderately drought-tolerant, but regular watering during dry spells is still beneficial.
- Pruning: Pruning is typically minimal for this tree. Remove any dead, damaged, or diseased branches as necessary. Prune selectively to shape the tree and maintain its clump-like form, preferably during the dormant season.
- Fertilization: Apply a balanced, slow-release fertilizer in early spring to promote healthy growth and vibrant foliage. Follow the manufacturer's instructions for dosage and application.
- Mulching: Apply a layer of organic mulch around the base of the tree, keeping it a few inches away from the trunk. Mulching helps retain moisture, suppresses weeds, and insulates the soil.
