Acer buergerianum drill abf-1-9

Trident maple, or Burger maple in bonsai

The bark is very decorative and peels off in patches, revealing light orange areas. Burger maple is extremely vigorous, especially when grown in the ground, and you can get towering trunks with beautiful nebari quickly this way.

It owes its name to the shape of its three-lobed leaves. If you're looking for a bonsai maple that's easy to grow and gives an interesting result quickly, then Burger Maple is for you!

Location: Outdoors all year round, the Buerger maple appreciates a semi-shaded location, especially in periods of high heat. In spring and fall, it will still need sun during the day to promote its branching and develop beautiful colors. In winter, protect it from heavy frosts (below -3°C) by using a winter fleece or glass wool and wrap the pot with it.

Watering: Maple trees need a substrate that is always moist. Water it regularly while allowing the root ball to dry out slightly between waterings to avoid excess water. In spring/summer, watering will be done regularly, when it's hot, it's every day ! On the other hand, in winter, water according to the supervision of the soil. Thanks to the rain and cold, you won't necessarily need to water regularly since the substrate will remain moist.

Important: Don't hesitate to water the entire root ball up to the roots, the water will drain away through the holes under the pot or bathe the bonsai in water (drenching) for a few minutes, to make sure you water it well. We do not recommend putting a cup/container under the pot as the water will stagnate and can cause root rot. (Too much water = asphyxiation).

Substrate and repotting: The trident maple likes cool soils with a good amount of organic matter. In the nursery, we use agricultural soil composed of black peat, blond peat, eco-aged, topsoil, horse manure, pozzolana. During the next repotting, which is done about every 2/3 years at the beginning of spring, you can mix more draining substrate such as: akadama, pumice, kiryu... Just be careful not to disturb the root ball, don't destroy the whole root ball!

Many bonsai react noticeably when repotted at the wrong time or too drastically.

Pruning: Pruning shoots and twigs can be done all year round. When the leaves have fallen, you can do a structure pruning and remove the superfluous branches. > How do you prune a maple tree?

Fertilization: In the nursery, we use blue tomato/flower fertilizer NPK 12 12 17. You can use some and put a handful (small or large depending on the size of the pot) on the substrate from May to October, every 2 months alternating chemical/organic.
