I have an Australian Tree Fern (Dicsonia Antarctica) which is about 3 years old. Over the past couple of years the crown has reduced quite significantly. I moved the plant to a more shaded part of the garden but the crown continues to reduce. I feed regularly with a high potash feed and lag the crown and the trunk over winter. Despite our last terrible winter it did survive but I'm wondering will the crown expand to its original size or will it continue to reduce. Also, what can I do to help this plant.



Stop the high potash feed for a start - potash is good for plants which flower prolifically, or are grown for their flowers and fruit, but no good at all for foliage plants. Don't feed at all again this year.
Should be in a shady, dampish, very sheltered position, watered into the crown and sprayed over the trunk regularly. Protect as you mention for this winter.

Thanks for your help - very much appreciated. My Plant is tucked up warmly for the winter now and I will do as you say next year - if it survives.

Many thanks again
