Also prune this way…

Tree ferns such as Dicksonia antarctica should also be unwrapped and pruned this month, after the last hard frost. However, rather than cutting part-way down the main stem, just snip off all of last year’s tatty old fronds individually 10-15cm from the point where they arise. Doing this means your tree fern’s trunk will grow taller – cutting the old fronds shorter than 10cm will cause the trunk to narrow as it grows. Your fern will then unfurl a whole new set of beautiful fronds from the crown of the trunk.
