How long do tree ferns live?
The tree fern species in this study can grow to over ten metres in height [15] and have been estimated to live more than 500 years [13], while other species in Australia have been recorded growing in excess of 15m, including the Norfolk Tree Fern, Cyathea brownii, which can grow to 20m [16].
Should I cut the old fronds off my tree fern?
