Plant my japanese maple ‘dissectum garnet’

Plant your Japanese maple in neutral or slightly-acidic, well-drained, cool, and even humid soil. Plant in full sun or partial shade, sheltered from drying winds. Anticipate how much space your tree will end up required based on the cultivar — it may be from 40 cm to 4 m! Dig a planting hole twice the volume of the root ball, loosen the sides of the hole, then sink a support into the bottom, facing prevailing winds. First add some soil to the bottom, then place the root ball so that the neck of the tree is level with the ground, then fill in the hole with soil around the root ball. Attach the trunk to the support with an appropriately flexible connector. Tamp down, form a watering basin, and water copiously. If potted, create a drainage layer with limestone-free gravel or any other rough granule, then plant the root ball in a mixture of good quality soil and decomposed compost. Cover with bark mulch.
