Acer Palmatum “Yamamomiji” – Pre Bonsai – Informal Upright
Acer Palmatum: also known as Japanese maple, or Momiji, it is extensively used as a bonsai due to its elegant palmate leaves, finely aging bark and spectacular seasonal color variation. It responds very well to most bonsai techniques and mature specimens combine impressive trunk taper with fine, detailed ramification. Many different cultivars and subspecies have been specifically selected for bonsai cultivation.
Yamamomij: The seed grown subspecies “Yamamomij”, literally meaning “Mountain Maple” (Acer Palmatum subsp. Matsumurae), is the most common Japanese maple bonsai type, combining vigorous growth and ease of care with the grace and elegance of the Acer Palmatum family.
Pre Bonsai: A young plant that has just started his bonsai journey. We have already pruned roots, added movement to the trunk and the right branches have been chosen. From now on, you can keep going just with regular pruning, or you can continue wiring and styling according to your taste.
Informal Upright/Moyogi: Arguably the most common bonsai style due to its essential and natural look. A single, upward-growing trunk with branches raising from the exterior of trunk bends.

Position: Full sun. Protect from extreme afternoon sun during hot summer if the plant has been recently repotted or is not completely established.
Watering: Frequent and regular, particularly in summer. Soil should not completely dry out between waterings. Observe and rely on leaves turgidness to read the plant watering needs.
Feeding: Depending on the desired growth rate, high nitrogen fertilisation after leaves appear in spring can be very effective, though leaf and internode sizes can get disproportionately large. A more balanced, less frequent fertilisation is advisable during the rest of the year until leaf drop.
Repotting: When buds start swelling in spring, roots can be pruned aggressively and old soil can be removed completely. Repot mature specimen every 3-5 years, young ones more frequently.
Soil Ph: Slightly acidic to neutral.
Pruning: Treat the 2 annual flushes of growth differently based on the desired target. Pinch the first 2 leaves as buds open to induce tight ramification and reduce internode size. Let shoots elongate and then partially defoliate them to construct new branches and avoid interior twigs die back. Prune higher branches more aggressively to balance strong apical dominance (though some varieties are naturally more balance or even basal dominant). Hard pruning should be performed during the mid summer dormant period, allowing callous formation and wounds healing.
Wiring: Young branches are very flexible and can be bent easily all year long. Extra care should be used though as branches thicken very quickly and wire-bite marks are very persistent.
Pests and Disease: High humidity level could favour the formation of fungal infections, mildew and verticillum among other. Aphids on spring new growth and mites are also frequent visitors. Excessive sun exposure and drougth can cause leaf scorch during hot summers.
