‘Leighton Green’ Conifer (X Cupressocyparis leylandii 'Leighton Green' - a cross between Cupressus nootkatensis and Cupressus macrocarpa) is an evergreen, fast-growing, drought and frost tolerant conifer. Ideal for hedges, privacy screens or as a wind break. In left unchecked, can grow up to 10-12 metres high.

How to grow Leighton Green Conifer in a garden

  1. Choose a position in full sun with well drained soil. Leighton Green Conifer are medium to large sized trees, best suited for medium to large sized gardens. Avoid planting near fences, walls and buildings.
  2. Enrich the soil with Yates Thrive Natural Blood & Bone with Seaweed and Yates Natures Way Organic Compost & Soil Improver. If the soil is clay based, add gypsum and fork in well. 
  3. Dig the planting hole twice as wide and to the same depth as the root-ball. Remove the plant from the container and gently tease the roots.
  4. Position in hole and backfill, gently firming down. Form a raised doughnut shaped ring around the plant, creating a well so that water will go where it’s needed most. Water in well. 
  5. Mulch with an organic mulch like woodchip or pea straw, keeping it away from the base of the plant.
  6. Water deeply, once or twice a week, depending on weather conditions.
  7. Feed with Yates Thrive All Purpose Granular Plant Food. TIP: for an added boost apply Yates Thrive Fish Blood & Bone Plant Food Concentrate.

Growing tips

  • ‘Leighton Green’ are remarkably drought tolerant for short periods, but plants will perform at their best if water stress is kept to a minimum.

  • Also available in a golden form X Cupressocyparis leylandii 'Castlewellan Gold'.

  • Pruning them late February or early March will ensure height and width is maintained as desired and avoids unnecessary plant stress.
  • If you do want them to grow to their full potential then they would require space at least 10 metres across for their branches to spread otherwise for a hedge, plant at a distance of 3 metres apart.

  • Avoid physical damage to the tree as this often leads to canker infection resulting in death of the tree.
