Growth Stages

1

Establishment

First 12 months

Young tree recovering from transplant shock with minimal growth; foliage may appear slightly stressed

Water consistently 2-3 times weekly. Stake if necessary for support. Protect from harsh winds. Avoid fertilizing the first year.

2

Early Development

Years 2-4

Weeping form becomes more pronounced; branches lengthen and develop characteristic drooping habit; foliage deepens in color

Water regularly but allow soil to dry slightly between waterings. Apply 2-3 inch mulch layer. Prune only to remove dead/damaged branches.

3

Vegetative Growth

Years 5-10

Tree establishes its weeping silhouette; slow but steady height and width increase; dense needle coverage achieved

Water during drought periods. Minimal pruning needed; allow natural form to develop. Watch for pest infestations in dense foliage.

4

Mature Form

Year 10 onward

Tree reaches its typical mature height (15-25 feet depending on cultivar); full weeping cascade apparent; cones may appear

Water only during extended dry periods. Prune only dead wood or to maintain shape. Monitor for spider mites and aphids. Mulch annually.

Avoid planting near:

Black walnut trees (juglone toxicity) Salt-heavy areas (avoid road salt spray) Hot, dry desert-adapted plants Highly competitive trees with shallow roots

Common Pests

  • Spray with strong water stream to dislodge; use horticultural oil or miticide if severe. Increase humidity around tree.

  • Spray with insecticidal soap or neem oil; prune infested branches if needed. Encourage natural predators like ladybugs.

  • Apply dormant oil spray in early spring before bud break. Remove heavily infested branches. Monitor closely.

  • Hand-pick bags in late fall/winter. Spray with Bt (Bacillus thuringiensis) in early summer if populations are heavy.

Uses

Harvest Tips

Not harvested for produce. Cones mature in fall (September-October) and can be collected for seed if desired, though this cultivar rarely produces viable seed. Branches can be pruned for fresh greenery arrangements.

Fun Facts

  • 🌱 The concolor fir is native to the western United States and is sometimes called the 'white fir' due to its pale, silvery undersides on the needles, which give it an overall bluish appearance.
  • 🌱 Unlike many weeping conifers that must be trained or grafted onto rootstocks, true dwarf weeping concolor fir cultivars develop their cascading form naturally, making them genetically stable and more vigorous than grafted alternatives.
  • 🌱 Concolor firs have an excellent fragrance—when needles are brushed or crushed, they release an aroma reminiscent of lemon or grapefruit, making them popular for holiday decorations and fresh greenery.
