Care Instructions
To care for Acer macrophyllum, provide it with plenty of direct sunlight and ensure it receives moderate temperatures. The tree prefers high humidity and should be watered regularly to keep the soil evenly moist. It is well-suited for outdoor growth in temperate climates.Soil
Acer macrophyllum prefers loamy soil that is well-draining yet retains moisture. The soil should be rich in organic matter to support its nutrient needs. Ensure the soil pH is slightly acidic to neutral.Fertilizer
Fertilize Acer macrophyllum with a balanced 10-10-10 fertilizer during the growing season. Apply the fertilizer once in early spring and again in mid-summer to support its growth and development.Repotting
As a large tree, Acer macrophyllum is not typically repotted. Instead, ensure it is planted in a suitable location with ample space for its roots to expand. If grown in a container during its early stages, transplant it to the ground once it outgrows the pot.Propagation
Acer macrophyllum can be propagated through seeds or cuttings. Collect seeds in the fall and sow them in a cold frame. Alternatively, take hardwood cuttings in late autumn or early winter and root them in a well-draining medium.Pruning
Prune Acer macrophyllum during its dormant period in late winter or early spring. Remove any dead, diseased, or crossing branches to maintain its shape and health. Regular pruning helps to promote strong growth and a well-structured canopy.Toxicity
Acer macrophyllum is not known to be toxic to pets or humans. However, as with all plants, it is advisable to prevent pets and children from ingesting any part of the tree.Additional
Acer macrophyllum is valued for its ornamental appeal and its ability to provide shade. It is also known for its sap, which can be used to produce maple syrup, although it is not as commonly tapped as other maple species.REVOLUTIONIZE YOUR PLANT CARE
