Coral Bark Japanese Maple (Acer palmatum ‘Sango Kaku’)

December 22, 2008 · by Chris · in Trees

The Coral Bark Japanese maple is a moderate to slow growing deciduous tree. Planted in sun to partial shade this tree tolerates a wide range of well drained soils. Growing 20-25 feet tall and 15-20′ wide.

Coral red winter bark gives this attractive specimen tree its name. Bark color is more intense when tree is planted in full sun. Deeply lobed light green leaves develop red margins and turn a golden yellow to red orange in the fall. Hardy in zones 5-8, avoid dry and windy site placement.

I have one of these trees.. I absolutely love it. It is going thru its first winter at our house. I hope it makes it thru OK. A windy day today… blew something down and broke of a small but significant branch.. I feel terrible and wonder if there is anything I can do to the broken spot.

When is the best time to prune Acer Sangokaku? Our tree is about to finish blooming. We never dared taste the cherries from it. Even the birds are not eating them either.

I hope to receive your kind response ASAP. Thank you.

  According to the folks at Mendocino Maples:
  
  Fall and winter is a common time to prune and shape deciduous trees and shrubs . Exceptions to this are maples which will bleed or ooze sap unless pruned when in leaf. When maples are pruned in late winter or early spring the wounds flow with sap. If heavy sap flow occurs, pruning should be delayed until midsummer. This flow of sap can lead to disease invasion and weakening of the tree. The preferred time to prune maples is between mid-July and August, a period when sap won’t run from cuts. The one time when trees should not be pruned is during early spring when buds are breaking during leaf expansion. Maples should be given a thorough pruning every three years and minor “touch up” pruning annually. A thorough pruning involves removing dead limbs, crossing branches (or branches that will cross in the future).
  
  Give newly planted trees and shrubs only minimal pruning. Removing too much top affects the production of food energy (carbohydrates) and can result in poor root development. After planting, prune out broken branches and those with weak or narrow crotches. With young trees, leave some of the lower limbs and sprouts even though they will be removed later. These limbs provide the closest source of food energy for root development. I have also found that trees will form a stronger trunk if the lower branches are not trimmed for a few years.
