Quick Overview

16" Tall Trident Maple Root over Rock Bonsai 12" plastic bonsai pot. If you like thick trunks, the Trident Maple is the tree for you.

This fast growing maple builds thick trunks more easily than just about any other species of bonsai, and trees with

amazingly massive trunks can be constructed. Branches are starting to develop nicely, tree is ready to wire and design.

Trident maple - Acer buergerianum
General information: This deciduous, 30 to 45-foot-high by 25-foot-wide tree in the wild, has beautiful tri-lobed leaves,

glossy green above and paler underneath, which turn various shades of red, orange, and yellow in autumn. Flowers are

bright yellow and showy in the spring. Trident Maple naturally exhibits low spreading growth and multiple stems but can

be trained to a single trunk and pruned to make it branch higher, allowing passage below its broad, oval to rounded

canopy. With its moderate growth rate, attractive orange-brown peeling bark, and easy maintenance, Trident Maple is

popular as a patio or street tree and is also highly valued as a bonsai subject. Crown form is often variable and selection

of a uniformly-shaped, vigorous cultivar is needed. The trident maple is a very popular species for bonsai, due to its

small, three-lobed leaves, a readily-thickening trunk, and thick, gnarly roots which adapt well to root-over-rock style.
Family: Aceraceae
Lighting: USDA states that this tree will grow in full sun, part sun or part shade. Tomlinson, writing from the UK, believes

this maple needs full sun. Simon and Schuster recommends partial shade.
Temperature: Although hardy in zones 4B through 9, the trident maple's roots have a high moisture content, and are

susceptible to frost damage. This is a potentially fatal problem experienced by members of the Internet Bonsai Club and

warned against in almost every book. Tomlinson goes so far as to suggest the substitution of Acer ginnala, the Amur

maple, in colder areas. At the very least, this tree should be carefully winter protected.
Watering: Water moderately in summer, easing off in winter.

Feeding: Tomlinson, as he usually does, suggests an aggressive feeding schedule: once weekly for the first month after

leaves appear, then every two weeks during growth. Simon and Schuster recommends feeding every three weeks during

growth, with an interval in midsummer. I've used the more conservative schedule with my tree and have been happy with

its growth, but find it entirely possible that more frequent feeding would improve the vigor of the tree. More frequent

feeding, however, requires increased vigilance in pinching back. If a liquid fertilizer is used, it should not be sprayed on

the leaves, as this may result in leaf burn.
Pruning and wiring: Pinch back new growth to the first two leaves. The tree may be wired at any time during growth, but

the branches are somewhat brittle and it is also wise to provide some protection for the bark. The tree, given ample pot

space, will grow rapidly, so it is essential to continually check the wire to avoid scarring. Leaf pruning can be carried out

in midsummer to miniaturize foliage. Make certain that the tree is healthy and vigorous before leaf pruning. Total leaf

pruning should not be carried out annually, as the tree needs a year to restore its stores of energy. I've been told that it's

safer to leaf prune gradually, removing only 1/3 to 1/2 of the tree's largest leaves at a time. The trident's leaves reduce

readily, but it is more difficult to get short internodes and finely ramified branches. For the more advanced/courageous

among us, Brent Walston suggests:
For smaller pieces, in one gallon training pots, I let them grow wild for 2 or 3 years until the roots completely fill the pot

and there is a noticeable decline in vigor. The internodes shorten and the leaves get smaller. It is at this point that I do

major pruning shortening them to under a foot. The depleted state of the roots due to the rootbound conditions prevents

them from forming the typical coarse growth that usually results following such a pruning. Performing this operation in

summer will have an even more dramatic effect, since in essence it is a radical (very radical) defoliation. Root pruning

and repotting can take place at the same time. As Michael [Persiano] would say, these are not procedures for

beginners. Once they are potted up and the final branches are selected, several defoliations a season will result in the

short internodes and small leaves so desired.
Propagation: Trident maple can be grown from seed, air-layered, or grown from both hardwood and softwood cuttings.

Tomlinson says that even wrist thick cuttings may take, and one instance of a six-inch (!) cutting being rooted

successfully has been reported. Best results are achieved taking cuttings in late winter-early spring for hardwood and

midsummer for softwood. Seeds require a 24 hour hot water soak, then cold-moist pretreatment for three months. Seeds

need to be stored refrigerated, which will start the cold- treatment process. Seeds kept in dry storage are tough to

activate, resulting in a poor percentage of germination. If you cannot collect your own seed, it seems that purchasing

fresh, properly stored seed from a reputable dealer is essential.
Repotting: In spring, before buds open. Roots grow very quickly, so annual repotting may be necessary for young trees;

older trees tend to need repotting every 2-3 years. If root die-back has occured during the winter, trim off old root matter

to allow room for new growth. Tomlinson recommends a fast-draining soil mix; The USDA states that Trident Maple

should be planted in any well-drained, acid soil and is quite tolerant of salt, air pollution, wind and drought. Like other

maples, some chlorosis can develop in soils with pH over 7 but it is moderately tolerant of soil salt.
Pests and diseases: Generally pest and disease free, but are vulnerable to caterpillar attack.
Species/varieties which make excellent bonsai:
Acer b. formosanum, the Taiwan or Formosan Trident.
"Mino Yatsubusa" and "Miyasama Kaede Yatsubusa", which exhibit various characteristics of being dwarfed.
"Goshika Kaede," a variegated form.
"Nartua Kaede" and "Tancho", two with unusual rolled-edged leaves.
"Evergreen's Rough Bark," valued for its bark appearance.
Closing Remarks: Trident Maple is a good beginner tree. It is not fussy with its soil requirements, and it can be shaped

by pruning, with wiring only necessary for initial shaping of the branches. Since it grows fast, a beginner will not lose

patience with it, and it is easy to create a specimen with a thick trunk in a relatively short period of time.
