The North Deck Garden is at our Ontario cottage outside of Toronto (zone 4). Like it sounds, the garden is beneath the deck, so it features shade tolerant ferns as well as daylilies, all harvested from roadside ditches in the area.
As per previous post, the daylilies had to come out because they were not going to fulfill their purpose of hiding where the fence meets the ground; they grow too much towards the lake and its sunlight. On top of that, the further under the deck they are, the less likely they are to bloom.
So I decided to move them to the front and change the garden from a 'fern patch', with ferns randomly filling the space, to a more traditional design with the big ferns at the back and the shorter daylilies in the front.
The daylilies are laying down in this photo after transplant but will come up fresh and vigorous next year, hopefully with enough sun to get at least some blooms.
(Just fyi - at the base of every pillar are two Clematis: one white and one purple.)
The three of five ferns I had to transplant were all massive and extremely heavy, my guess is fifty pounds.
To keep earth from covering the lawn I always place transplants on a nearby tarp. Having them all collected also helps me to get a sense of how much material I have to work with.
Viper's Bugloss, but I do not expect it to come back, it has such a large tap root it is not a good candidate for transplanting.
I will post some progress photos in early July, by which time I expect it to have filled out quite nicely and a previously muddy patch will have been transformed into lush greenery.
