Splitting a Tree Philodendron (Philodendron selloum): To Divide or Not?

A mature Philodendron selloum with multiple stems in one pot can be divided, but it’s risky. The roots are intertwined; separating them damages both plants.

Better Approach

• Leave them together—they don’t compete and will fill the pot attractively.
• If you must divide, use a sharp knife to slice a smaller stem with roots, root in water until 1″ roots form, then pot in a small container.

Propagation Alternative

Take stem cuttings from taller stems, root in water, and pot up for new plants without disturbing the mother.
