Winter hardiness is the most common cause of concern for tree ferns. The growing point at the top of the trunk is most vulnerable and mustn’t be allowed to freeze. Generally, the hardiness of a tree fern increases as the trunk gets taller and the growing point is higher off the ground. Tree ferns will take a temperature of -10C for a short period; prolonged winter freezing can do irreparable damage. I use a good couple of handfuls of straw plunged into the crown of the tree fern. I then pull up the fronds and tie them together with horticultural fleece. Don’t worry about damaging the fronds as these will be cut off later in the season when winter protection is removed. #treefern #dicksoniaantarctica #treeferncare #gardeningtips #gardeningadvice #mygardentoday #gardening #gardener #wintergarden https://www.instagram.com/p/BsKt4wBFGsj/?utm_source=ig_tumblr_share&igshid=12u57kzy63e2
