Coral Bark Japanese Maple (Acer palmatum 'Coral Bark') is a beautiful cultivar known for its vibrant red foliage and compact, upright habit.

USDA zones 5-8. It may tolerate slightly warmer or cooler conditions depending on local microclimates, but it generally prefers these zones.

Sunlight: Japanese maples prefer dappled shade or partial sun. While they can tolerate some direct sunlight, especially in the morning or late afternoon.

Soil: Well-draining, slightly acidic soil is ideal for Japanese maples. They don't like wet feet, so avoid waterlogged or compacted 

soil. Amending the soil with organic matter like compost can help improve drainage and fertility.

Watering: Japanese maples prefer consistently moist soil, especially during their establishment period. Once established, they are somewhat drought-tolerant but will benefit from regular watering during dry spells, particularly in hot weather.

Mulching: Applying a layer of mulch around the base of the tree helps retain soil moisture, regulate soil temperature, and suppress weeds. However, be careful not to pile mulch against the trunk, as this can promote rot and fungal issues.

Pruning: Pruning is generally minimal. Remove any dead, damaged, or crossing branches to maintain the tree's health and shape. It's best to prune in late winter or early spring before new growth emerges.

Fertilizing: Japanese maples generally don't require heavy fertilization. A balanced, slow-release fertilizer applied in spring can provide the necessary nutrients for healthy growth.

Protection from Winter Winds: In colder climates, particularly at the edges of its hardiness zones, providing some protection from harsh winter winds can help prevent desiccation and damage to the foliage.
