Cutting a 20 gallon potted Running Bamboo tree to split and replant.

Question

What type of saw and method works best for splitting large potted Bamboo Tree for propagation.

Answer 1

Wedge a small knife or garden tool between the soil and sides of the pot. Run the tool along the edge to loosen the soil ball from the container.
Tip the pot on its side and carefully pull and twist the bamboo until it comes out of the pot.
Cut the old, clumping roots from the bottom of the root ball with a pruning saw or reciprocating saw. Saw straight through the soil, removing the bottom 1 to 2 inches of the root ball height.
Shake the excess soil from the root ball and rinse with water, if necessary, to reveal the bamboo root system. Inspect the root ball for natural points of division.
Cut the entire root ball with a pruning saw or reciprocating saw into sections. If you cut about halfway through the soil ball, you can usually pull the plant apart with your hands, making it easier to follow the natural points of division.
Repot these sections.
