Growing tips:
Location: Outdoors all year round, it is preferable to place the Atropurpureum maple in partial shade, especially during the hot weather, but it needs the sun to promote growth and develop beautiful reddish colours. In summer, we therefore advise you to give it an EST exposure so that it can enjoy the morning sun while protecting it from the scorching sun. In winter, maple is not afraid of frost but to be on the safe side, protect the roots, so use a winter fleece or glass wool for example and wrap the pot with it. So, with this protection, you can leave it outside without any problems.
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: 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.
Waist: Pruning shoots and twigs can be done all year round. Strong branches should be harvested in autumn to avoid excessive sap loss, or in summer.

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.
