Thuja occidentalis ‘Unicorn’ is a distinctive and elegant evergreen conifer valued for its refined, conical form and rich dark green foliage that provides year-round structure and colour. Its naturally graceful shape makes it an excellent focal point in garden beds, while also working beautifully in borders or as a specimen planting. Thriving in full sun to partial shade and well-drained soil, this hardy variety benefits from regular watering during dry periods and some protection from strong winds. Easy to maintain and visually striking, ‘Unicorn’ adds a unique and polished touch to both traditional and modern landscape designs.

Conifers

🌱 Conifer Care Guide Conifers provide year-round structure, colour, and texture to the landscape, making them a reliable foundation in garden design.

For best results, plant in well-draining soil and enrich with compost or peat moss to support strong root development and healthy foliage. Choose varieties suited to your space and light conditions, and water regularly while plants establish. With proper care, conifers maintain their shape and colour, contributing lasting visual interest in the garden.

Spring
  • Plant evergreens once the ground has thawed and planting conditions are workable.
  • If transplanting into a garden bed or changing soil, mix in compost to support root establishment.
  • Water thoroughly after planting to settle soil around the roots.
  • Begin fertilizing with a slow-release or balanced fertilizer as new growth appears.

Summer
  • June–August, water regularly during establishment and extended dry periods.
  • Monitor for signs of stress during heat or drought.
  • Prune lightly if needed to maintain shape or remove damaged growth.
  • Fertilize only if planted in new or amended soil to encourage steady growth.

Fall
  • September–October, continue deep watering until the ground begins to cool.
  • Stop fertilizing to allow plants to harden off before winter.
  • Avoid heavy pruning, removing only dead or broken branches.
  • Mulch the base to help insulate roots and retain moisture.

Winter
  • November–March, evergreens remain dormant but retain foliage.
  • Water during mild periods if soil is dry and unfrozen.
  • Protect from heavy snow or wind damage when necessary.
