Pine Bark Fines aged and composted from Ontario sawmills is a great base as it retains moisture while not waterlogging (protecting from root rot), provides nutrients and drains very well.
This is undoubtedly the best substrate base for developing young Bonsai. Unlike substrates used for refinement (finishing a bonsai tree in a bonsai pot), Pine Bark fines is the best soil type to thicken trunks, develop branching and all other stages of Bonsai development. Best used in growing pots, this substrate is not Pine Bark Mulch. It has been refined into smaller particles and composted to provide an ideal base to plant your developing trees in.
Our Pine Bark fines come in 1.5L and 3L bags.
1.5 L will be sufficient for a 6" Azalea pot or colander.
3L will be sufficient for a #1 Gallon grower pot.
