Split-Leaf Philodendron: Two Species, Neither Divisible Unless Multi-Planted

Melanie's 3-yr split-leaf philodendron in largest pot, rootbound. Asks: split? how? when? Summer out/winter in.

Two "Split-Leaf" Species

1. Monstera deliciosa — large vine, perforated leaves.
2. Philodendron selloum (now Thaumatophyllum bipinnatifidum) — tree-like, deeply lobed.

Neither Divisible (Unless Multiple in Pot)

• Monstera = single vine; can't divide.
• Philodendron selloum = single trunk; can't divide.
• Only separable if >1 plant in pot.

No Need to Divide

Both tolerate rootbound for 20+ years. Repot larger only if you want bigger plant. Current pot fine with proper light/water/fertilizer.
