Plants requiring full, intense sun in hot climates Shallow-rooted competitors that demand excessive moisture Black walnut (Juglans nigra) - produces allelopathic compounds Areas with poor drainage or standing water

Common Pests

  • Spray with water to dislodge; use neem oil or insecticidal soap if infestation is severe; maintain adequate moisture to reduce stress

  • Hand-pick and destroy bags in fall/winter; apply Bt (Bacillus thuringiensis) in early summer when caterpillars are small

  • Prune out infected branches well below visible damage; disinfect tools between cuts; improve air circulation; avoid overhead watering

  • Remove affected foliage; ensure good drainage and air circulation; avoid wetting foliage; apply copper fungicide if severe

  • Ensure excellent drainage; avoid overwatering; improve soil aeration; plant in raised bed if drainage is poor; remove severely affected trees

Fun Facts

  • 🌱 Weeping Alaskan Cedar is not actually a cedar but a false cypress (Chamaecyparis), and despite its name, it is native to coastal British Columbia and southeastern Alaska, not Alaska in general.
  • 🌱 The foliage releases an aromatic, slightly spicy fragrance when brushed or crushed, which comes from volatile oils in the needles and is often described as citrusy or resinous.
  • 🌱 In its native habitat, the species can live over 3,500 years, making it one of the longest-living trees in North America, though the ornamental weeping cultivar typically has a lifespan of 100-200+ years in cultivation.
