advise me on how to transplant a large king fern. I planted it under
our terrace 20 years ago and it is now far too large for this position.
The fronds hang over two pathways and the top touches the terrace.
ferns transplant quite readily. Probably the best approach is to
cut back all the large fronds to make handling easier. Leave a stump
about 20-30cm long at the base of each frond, which you'll probably
find useful to grab hold of when shifting the plant once it's dug
Use a sharp spade to
cut through the roots, pushing it into the soil as far as you can,
about 30cm or so from the base all around the plant. Lever the fern
up and out, and place on to a tarpaulin, cutting through any remaining
roots with secateurs. Try to keep as much soil around the roots
as possible. Wrap the root ball in the tarpaulin to prevent soil
dropping off and drag or lift it to its new position. Watch your
back - it will be quite a heavy load.
Replant, water well and
mulch, then simply wait for new fronds to grow. Water regularly
if necessary to keep the soil moist and encourage new root growth.
