Shrubs and Trees for Mountain Communities (6,000 ft – 10,000 ft)

Check soil moisture and drainage, and make sure the sun exposure is correct for the plant. Be aware of the frost-free period. Plant shrubs in early spring, fall and summer planting should be avoided. Gradual exposure to more difficult temperatures will help shrubs considerably. Mulches help to delay freezing of the soil in the fall but must be removed in early spring to allow the soil to heat up.

Trees

Trees have the most restrictions for plants at high elevations. Establishment can be very difficult, so:

  • Check soil for adequate drainage and water-holding capacity and add peat or compost.
  • Plant as early in the spring as the soil can be worked, no fall or summer planting.
  • Regrowth of roots is the most important factor of transplanted stock. Extend the growing season for roots by applying a 4-6” mulch of pine needles, wood chips, organic material, etc., on the surface before the ground freezes in the fall, and then remove in early spring. Snow cover is also an excellent mulch, which allows root growth even during the winter.
  • Snow will accumulate best around a tree if a barrier is placed on the opposite side the wind blows from. Wrap non-evergreen tree trunks with Tree
  • Wrap to the 2nd branch for protection, for the first 2 seasons.
