Tree Ferns After a Harsh UK Winter: Assessing Survival and Future Protection

You’ve had three Dicksonia antarctica tree ferns for 11 years. After a bad winter, one fermented in the crown and the other two haven’t resprouted. They’re in fertile, moist soil with only evening summer sun in a north-facing garden.

Verdict

If no growth has appeared by now, they’re likely dead—especially the rotting one. Sometimes the main plant dies but “pups” emerge from the sides; check for those.

Future Protection

• Plant in a spot sheltered from north winds.
• Mulch heavily with straw in fall.
• Ensure excellent drainage to prevent root freezing and rot.

Sorry for your loss—these are magnificent plants worth trying again with better winter prep.
