How to propagate by division
Division multiplies Boston fern by splitting the root ball in spring, so each section has its own roots and shoots. The new plants settle in quickly because they already have a mature root system.
- 01
Water the plant thoroughly the day before dividing: well-hydrated roots are more resilient.
- 02
Slide the plant gently out of its pot. If it’s stuck, run a knife around the inside edge.
- 03
Shake off the loose potting mix to expose the root system. For clumping plants, you’ll see distinct crowns or growing points.
- 04
Tease the clumps apart by hand where possible. For tightly bound roots, use a clean sharp knife or pruning shears. Each section needs at least one healthy shoot and a decent portion of roots.
- 05
Pot each division into fresh, well-draining potting mix at the same depth it was growing before.
- 06
Water gently, then keep the divisions out of strong direct sun for 1–2 weeks while they settle. Skip fertilizer for the first month.
- 07
New growth is the sign that the plant has adjusted. After 4–6 weeks, resume normal care.
