Tree Fern Survival
What's the current thinking on protecting tree ferns over winter ? I've wrapped up the trunks in fleece and blankets but what about the top growth ? At present mine look really good and I don't really want to cut them back. Last year I wrapped them together - again using fleece and pillow-cases (!), stuffed some straw amongst them and they survived quite well. Obviously I eventually needed to cut back the dead growth but I wondered if leaving the fronds on over winter helped to protect the new growing points. Would appreciate any thoughts on this.
