Mechanical spade transplanting results:
Initial tree-spade results look promising. In early April we used a 72" tree spade to move the following plants:
1 Koelreuteria paniculata 4-5"
3 Pinus densiflora 'Umbraculifera' 12/14'
1 Pinus nigra 10/12'
5 Pinus strobus 'Nana' 6/8'
1 Parrotia persica 10/12'
2 Tsuga Canadensis 'Sargenti' 5/8'
9 Picea unknown 12/16'
With minimal manual irrigation, all of the plants survived their first year. The Picea showed more elongated growth and less density of habit.
In late April we moved 10 Sciadopitys verticilata 10/12' with our 42" tree spade. The trees received minimal manual irrigation. All survived, showing minimal signs of stress, discoloration, etc. We spaded 15 additional Sciadopitys verticillata 8/14' in October. Trees received minimal manual irrigation. All appear to be doing well, showing only minor discoloration
72” Mechanical spade results, update:
1 Koelreuteria paniculata 4-5” FAIL—improperly back filled
3 Pinus densiflora ‘Umbraculifera’ 12/14’ SUCCESS
1 Pinus nigra 10/12’ FAIL--needlecast
5 Pinus strobus ‘Nana’ 6/8’ SUCCESS
1 Parrotia persica 10/12’ SUCCESS
2 Tsuga canadensis ‘Sargenti’ 5/8’ SUCCESS
9 Picea unknown 12/16’ SUCCESS
25 Sciadopitys verticilata 8/14’ SUCCESS
Fall Division of Perennials:
During the autumn of 2012, we performed a large-scale perennial divisions to alleviate crowding. Most perennials responded well. However, some plants struggled or did not return:
Anemone tomentosa ‘Robustissima’ did not perform well the following year in the garden, and failed to over-winter in containers above ground.
Chrysanthemum ‘Sheffield’ did not respond well and failed to overwinter in containers above ground. The variety ‘Venus’ did very well in both instances.
The Nipponanthemum nipponicum (Montauk Daisies) responded surprisingly well; overwintering above ground in containers and growing into a nice shrubby shape in the garden.
The Caryopteris also responded surprisingly well in the garden—showing a nice shrubby shape and heavy flowering.
We are investigating how to successfully
transplant trees and shrubs outside the normal season. One example:
