Maintenance
It is difficult to properly prune ground cover Junipers. Most people just cut the ends and after a few years pointed stubbed branches form. Lift up the outside branches cutting the underneath branches and feather back the top branches to a crotch of a branch. This will develop into a much softer outside edge of the shrub. Also they will have branches that just seem to die for no apparent reason and these will need to be cut out using pruning shears
Propagation
cuttings
Cultivar Origin
Native to the Vinalhaven Island off the coast of Maine (USA). Introduced by the South Wilton Nursery in Connecticut (USA) in about 1914.
Misc Facts
