Japanese maples (Acer palmatum and cultivars) are extraordinarily beautiful
garden trees, prized, admired and planted extensively for centuries in ornamental
horticulture.They are definitely worthy of the adoration plant lovers extend
to them. Grow
them for the wonderful foliage color and winter branching structure.
Plant Depot proudly offers both green and red leaf seedlings. Seedling maples
are not grafted. They grow much faster and larger than grafted types.
We receive only one or two shipments per year, so the selection is for a very
limited time. Japanese maples can grow in containers or in the ground.
In warmer inland areas, a sheltered location - such as in a courtyard or on the
north side of the house - is crucial for success. Any combination of strong sunlight,
alkaline or salty soil, and dry winds can result in scorched leaf edges by midsummer.
And that scorching usually ruins the fall color. Otherwise they appreciate a
good amount of direct sun; the red leaf type especially needs it to develop good
color.
There are hundreds and hundreds of cultivars of Japanese maples. Of course,
you won't find all of them here at Plant Depot, but you will find those varieties
that will do well here. Still, you will have many to choose from. So how do you
make your final selection(s)? Consider tree form, foliage shape and color, cultivar
needs and the desired effect or look that you are trying to achieve.
Japanes maples are attractive in groves (like birches) or singly in woodland
plantings including ferns, azaleas, columbine, and hosta. There are upright forms
and weeping forms, coral-colored bark that just 'pops' in winter. All leaf shapes
are palmate or the classic maple shape, like the palm of your hand. Some are
classically cut, others are deeply cut-leaves, giving the tree a lacy look. Spring
color in most varieties is reddish-pink to pink. Summer colors range from burgundy
to green to variegations of green, pink and white or cream. Fall colors can be
yellow to orange to deep red-orange to red; again, depending on variety.
But fall color is only one of the only reasons to plant a Japanese maple.
Few other trees are so well behaved. Their roots are noninvasive; their fallen
leaves break down quickly or blow away in the wind, making autumn cleanup easy;
and even the taller varieties can usually be pruned from a stepladder. The Japanese
maple is an excellent choice for the smaller garden or use as a patio tree.
Japanese maples also deliver four seasons of garden interest. In winter, their
bare branches (they are deciduous) have a rare structural beauty - some highly
colorful, others with graceful weeping silhouettes. The branch pattern can be
strongly upright on trees over 20 feet tall, or weeping and dome-shaped on shrub-like
trees less than 4 feet. Some varieties have green, red, or variegated bark.
Unfortunately, many homeowners purchase a beautiful Japanese maple in spring
only to watch the leaves get burned in summer. We get panicked calls from customers
fearing that they have killed their beautiful young tree. The tree isn't dying
- it's just suffering from heat stress, chemical burn from buildup of salts in
the soil, incorrect watering, or maybe even incorrect placement in the yard.
"So," you ask, "What do we do to minimize the leaf burn?" Start with planting
it properly. Materials needed for planting: peat moss, pumice (if the soil is
clay), cottonseed meal and shredded bark. Maples require acidic soil (peat moss
is acidic). Cottonseed meal not only provides nutrients it also acidifies the
soil. Spreading used coffee grounds (like grandma did) under and around the plants
also acidifies.
White vinegar diluted 3-4 tablespoons
per gallon of water is yet another way to minimize build up of salts in the soil.
And always be sure to top off your soil with mulch to keep the soil cool and
moist. Remember that chemical
fertilizers are made of salts (ammonias, nitrates, etc.) Plus, in Southern California
our water comes from the Colorado River - which has a fair amount of lime in
it (from the Grand Canyon). When the water evaporates the salts remain, so by
reducing the evaporation rate (with 2-3 inches of surface mulch) we reduce
the rate of salt build up.
Also note:
never plant a Japanese maple in a low spot or near an area that may have standing
water, or your new tree will succumb to root rot.
Japanese maples are the spotlight of any garden as they pose with complete
elegance any time of year. These trees will bring beauty to your garden
forever. Welcome one into your garden; you'll see just what we truly mean.
