  1. 'Flamingo Maple' ('Orido Nishiki') - 15 to 18 feet tall with a top that may have a similar spread.
  2. 'Cutleaf' - 8 to 10 feet tall with a similar top spread.
  3. 'Tamukeyama' - 4 to 6 feet tall with a similar spread.

 

5. Bloom Time - N/A.

6. Planting Instructions - See Below.

A. Dig a hole large enough to give the roots plenty of room with a few inches of space beyond the root tips and the sides of the hole. Build a mound of soil in the bottom of the hole and spread the roots in a natural position atop the mound.

B. Position the plant so that the previous soil line will be even with ground level. The stem/trunk will be darker in color below the original planting line and lighter in color above it.

C. Once the plant is positioned at the proper planting depth begin filling the hole with soil. Work the soil around the roots with your hands. When the hole is half filled tamp the soil to remove any air pockets.

D. Fill the planting hole with water and allow it soak in. Straighten the plant in the hole and finish filling with soil.

E. Form a "saucer" of soil around the edges of the planting hole and fill it with water.

F. Stake the tree to assist the roots in getting anchored. Staking will also maintain upper balance so that the trunk will continue to grow straight.

GET THE MOST ENJOYMENT

Japanese Maples do fine in various degrees of shade so if other trees are planted close by they suffer no adverse effects from the crowding.  They perform excellently in urban settings where large buildings deny gardeners much in the way of full sun options. They are rarely attacked by insects and or injured by air pollution. You can even plant them in large pots for the porch or patio or near a house without putting the house at risk.

 

SOIL PREPARATION

Although these plants will perform well in average garden soils of all types, we recommend having your soil tested periodically by the local County Extension Office.  These tests can determine if the soil needs any amendments to enhance your plants' growth and performance.  See below for our recommended practice to improve your soil without any additional testing:

1. Spade or rototill the soil to a depth of 12-18".

2. It is always good to add organic matter to your soil. You can mix in a 2-4" layer of dehydrated manure, garden compost, shredded leaves and/or peat moss.

3. After active growth begins, periodically feed with Cottage Farms' water soluble Carefree Bud-N-Flower Booster.

CONTINUING CARE

Watering - Adequate and consistent watering is essential during the plant's first year in your garden.  Infrequent, long soakings of water that thoroughly saturate the soil surrounding the root zone are more effective than frequent light applications of water that may wet the top of the soil only.  

Due to individual plant needs, geographical and environmental conditions, a specific watering schedule is hard to define; however as a rule of thumb you should not allow the soil to completely dry out.  During periods of drought and extreme summer heat, you may need to water as often as every day.

Overwatering can be as damaging as under watering.  Be sure that the area surrounding your plant does not become a water-holding bog and that there is adequate drainage to move excess water away from the plant.  

Mulching - Apply a 2-4" layer of shredded bark, compost or other organic mulch around your plants to promote moisture retention, maintain even soil temperatures, and to discourage weed growth.

Weeding - Keep the area around your plants free of weeds. Weeds compete with all plants for food, water and light. Walk around the garden periodically and pull weeds, including the roots, as soon as you see them. Mulch also assists in keeping weeds down.

Grooming - Improves the size and quality of the tree and maintains a healthy, happy plant for many years. Remove any branches that become overlapped, damaged, or unsightly.

Feeding - Discontinue feeding after September 1st so your plants can harden off for winter dormancy. Resume fertilizing when new growth appears in Spring and feed once every 2 to 3 weeks.

Winterizing - A thorough watering in late fall will greatly enhance the plant's cold tolerance.

 

The time to protect your plants in the garden is after the ground has frozen. At that time, apply a winter mulch of evergreen boughs, straws or leaves to prevent lifting of the plant's roots during alternating periods of freezing and thawing.

 

For container planting, move plants next to your home's southern foundation for added warmth and protection. They may also be moved into an unheated, protected area such as a garage or cellar.  If moved to a protected area, be sure to check the soil moisture every 2 to 3 weeks and water as needed.

 

In spring, remove the mulch from in-ground plantings.   Also, bring containerized plants back out into the garden sunlight where they will immediately begin to repeat their yearly garden performance. 

CAUTION: Not all plant material is edible. Though most plants are harmless, some contain toxic substances which can cause headaches, nausea, dizziness, or other discomforts. As a general rule, only known food products should be eaten. In case of ingestion, please contact your local poison control center at once and advise them of the plant ingested. Keep out of reach of children.
