Coral Bark Japanese Maple

Sunlight

Your Coral Bark Japanese Maple will thrive in either full sun or part shade. In very hot climates, some afternoon shade can be beneficial to prevent leaf scorch.

Watering

Water regularly, especially during the first few years after planting. Aim to keep the soil consistently moist, but avoid soggy conditions. Established trees are drought tolerant but will appreciate occasional deep watering during dry spells.

Soil

While adaptable, the Coral Bark Japanese Maple prefers well-drained soil. If your soil is heavy clay, consider amending it with compost or other organic matter to improve drainage.

Spacing

Provide enough space for your tree to reach its mature size (15-25 feet) without crowding other plants or structures.

Pruning

While not strictly necessary, light pruning can be done in late winter or early spring to maintain the desired shape and remove any dead or diseased branches.

Monitoring

Keep an eye out for signs of pests or diseases, and address any issues promptly.

Mulching

Apply a 2-3 inch layer of mulch around the base of the tree to retain moisture, suppress weeds, and regulate soil temperature. Keep the mulch away from the trunk to prevent rot.

When It Arrives

Give your newly planted Coral Bark Japanese Maple a deep and thorough watering to soak the root ball and surrounding soil.

During The First Year

Water regularly throughout the first year, especially during hot and dry periods. Aim to keep the soil consistently moist, but avoid leaving the roots sitting in soggy soil. A good rule of thumb is to water deeply when the top few inches of soil feel dry to the touch.

After the First Year

Established Coral Bark Japanese Maples are drought tolerant and can survive on rainfall in most climates. However, occasional deep watering during extended dry spells will be beneficial, especially during the hottest part of summer.

Extra Tips

Water slowly and directly at the base of the tree, allowing the water to penetrate the root zone. Avoid shallow watering that only wets the surface of the soil. For container-grown trees, water until water runs out the drainage holes, then empty any saucer to prevent waterlogging.

When It Arrives

Newly planted Coral Bark Japanese Maples typically have enough nutrients from the nursery to establish themselves. Avoid fertilizing during the first few months after planting.

During The First Year

You may consider a light application of a balanced fertilizer in early spring during the first year after planting. Follow the application instructions on the fertilizer label carefully and avoid over-fertilizing.

After The First Year

Mature Coral Bark Japanese Maples generally don’t require regular fertilization. However, if your tree shows signs of nutrient deficiency (such as pale leaves or stunted growth), a light application of a balanced fertilizer in early spring can be beneficial.

Extra Tips

Less is often more when it comes to fertilizing Japanese Maples. Over-fertilization can lead to excessive foliage growth at the expense of flower and fruit production (not applicable to Coral Bark Japanese Maple) and can weaken the tree’s resistance to pests and diseases. Opt for a slow-release fertilizer specifically formulated for trees and shrubs.

What Tools are Needed

For most pruning tasks, a good pair of sharp bypass pruners will suffice. For thicker branches, lopping shears may be necessary. Always ensure your tools are clean and sharp to avoid damaging the tree.

Pruning Steps

The best time to prune Coral Bark Japanese Maples is in late winter or early spring when the tree is still dormant. Focus on removing any dead, diseased, or damaged branches. You can also prune to maintain the desired shape, removing crossing or crowded branches that rub together. Make clean cuts at a 45-degree angle just above a bud facing outwards.

After Pruning Care

Apply a dab of pruning sealant to larger cuts to help prevent disease and promote healing. Avoid excessive pruning, as Coral Bark Japanese Maples naturally develop a beautiful branching structure.

Extra Tips

It’s best to err on the side of less when pruning Japanese Maples. Major pruning can negatively impact the tree’s health and appearance. If you are unsure about a pruning cut, it’s best to wait until you consult with a professional arborist.
