The dark green, Weeping Norway Spruce can be staked and trained into an outstanding upright specimen, or it can be allowed to grow as a ground cover that drapes over slopes and rocks.
Whistling Gardens Darren Heimbecker planted a row of young ‘Pendula’ plants with stakes and wire supports to train them into a narrow, living fence.
As for the culture of Weeping Norway Spruce, they prefer moist but well-drained soil in full sun to light shade. They are hardy from Zones 2-8 . They are generally pest free and once established, are very little trouble at all.
One thing you will have to determine is whether you want an upright tree or a low mounding form. If you opt for the upright version, you’ll have to stake and train an upright leader so that the plant knows you want it to grow up .
If allowed to grow into an upright plant, it will ultimately reach a height of 15′ or so but that will be after many years of growth.
