Japanese Maples

Acer palmatum

 

These beauties have become a popular addition to Tulsa landscapes, and for good reason! Their beautiful foliage and graceful appearance can make a vocal point out of the most drab corner in your landscape. Add a couple of flats of beautiful blooming annuals and you’ve got a gardeners’ oasis right in your own yard. Just keep in mind, a Japanese maple in the Tulsa area requires afternoon shade. They will keep their color with some good morning sun, but the hot Oklahoma afternoons will burn the foliage. Your Japanese maple also needs some protection from harsh winds.

You will find many books and articles that tell you they can withstand full sun…trust us, they cannot! There are many distinct genus-species of Japanese maples: one is called Acer palmatum which has leaves more like the traditional Japanese maple and another is Acer palmatum dissectum which is the lacy leaved variety. Yet another is Acer shirasawanum which has a fatter leaf, but it is not lacey.

Planting:

To plant your Japanese maple dig the hole about twice the size of the root ball. If you are planting it under another tree be careful not to damage the roots of the larger tree.  If you have poor soil, amend it with Back To Nature® to give your tree a good start.  Water slowly and thoroughly while back-filling.  Mulch with a good 2-3" layer avoiding getting the mulch right up next to the trunk of the tree.  If your tree is in balled and burlapped form, completely remove the burlap before placing in the hole.

Care and Maintenance:

  • Japanese maples can be pruned to fit your design and purpose. 
  • Light pruning can be done any time of the year.
  • Heavy pruning may be done early in the spring, or late winter while they are still dormant.  Keep in mind never to take off more that ⅓ at a time.
  • Mulching is a must because of their shallow root systems.
  • Feed once in the spring with a good all-purpose fertilizer.
  • Leaf scorch can occur by the sun and the wind.  This is the reason site protection is important.
