How to divide crispum hart's tongue fern
Lift the clump, shake off loose soil, then prise it apart — two forks back to back for a tough clump, hands or a knife for a softer one. Keep the vigorous outer sections and discard the tired centre.
Aftercare
Pot each division into fresh compost at the same depth it was growing before, water it in well, and keep it somewhere bright but out of direct sun for two to three weeks while new roots take hold. Do not feed straight away — damaged roots take up fertiliser poorly and it can scorch them.
The mistake to avoid
Splitting crispum hart's tongue fern into too many small pieces. Each one then spends a season just recovering; three or four solid divisions beat a dozen weak ones.
