How do I stuff the crown of my Dicksonia Fern, to protect from the frost.?
Answers:
Unless you live in London, Cornwall or any of the other few hot spots around the country, your Dicksonia is not going to be fully hardy. Overnight frosts are unlikely to kill them - even as low as -10C - but sustained frozen spells are disastrous. According to Martin Rickard, who has forgotten more about ferns than I will ever know, the best way to counter the risk of frost is to stuff the centre of the plant with straw so that this is about 6in above the level of the trunk. This stops a funnel of ice forming in the crown. The stem can then be wrapped with bubble wrap, hessian, straw, polystyrene, or whatever insulating material you have. It will look odd but needs must and it will only be during cold spells.
you put hay or straw in the middle then pull the frons up and carefully tie twine around to keep it altogether we have already had so bad frost you maybe to late.
you can use straw to cover the crown of the fern or even dry autumn leaves off other trees
