Description

Thuja OC Smaragd

The Thuja OC Smaragd (175cm – 200cm), an American or Californian variety of Deodar Cedar, is a well-liked foliage shrub for hedges because it retains its vivid green color throughout the seasons. The superficiality of the plant makes it easy to be grown even in normal, clay, or chalky soils such that once again it is practical. It enjoys full sun to semi-shade with inland or exposed situations well to broaden the valuing of the gardens in various climatic conditions.

This Thuja being an average growing type at a location of average annual growth of 20-40 cm is easily maintained within a range of 1-4 meters which makes it a perfect shrub for pruning as low or tall hedges. The hedge will provide attractive foliage from spring to winter as the alternate plan is made to be more appealing in all seasons. One meter distance is needed to plant 2-3 plants in order to have easy access for the neatly trimmed hedge.

People who want to grow natural privacy, windbreak screens or attractive features without too much maintenance will love this fast growing screen which requires very little maintenance.

How To Plant

Choose the right pot

Pick one 2–3× wider than the rootball with drainage holes. Add a saucer if it’s on a patio, but never let the pot sit in standing water.

Prep your mix (pots)

Use quality peat‑free multi‑purpose compost blended with roughly 20–30% grit or perlite for drainage. You can mix in a small handful of slow‑release fertiliser granules following the label.

Potting steps

Cover the drainage holes with crock or mesh, add a 3–5 cm base layer of compost mix, and gently tease the outer roots. Position the plant so the top of the rootball sits level with the pot rim, backfill and firm lightly to remove air pockets (don’t bury the stem), then water thoroughly until it runs from the base.

Positioning (both)

Choose a bright spot with a few hours of sun and shelter from strong, cold winds. For pots, raise the container on feet or small blocks to keep the base off the ground and prevent waterlogging.

Watering (both)

Keep the root zone evenly moist during the first season. Check moisture 3–5 cm down and water deeply when dry. In heatwaves expect to water every 1–3 days in pots and about two to three times per week in the ground; in winter, water far less but do not allow the rootball to become bone‑dry.

Feeding (both)

In spring, apply a slow‑release fertiliser as directed. From late spring to mid‑summer, an optional liquid feed every three to four weeks helps container plants perform at their best.

Pruning & shaping (both)

Lightly trim after the main flush of new growth to keep the plant dense and tidy. Remove dead, damaged, or crossing stems whenever you see them.

Mulching (both)

Apply a 2–3 cm mulch of compost or fine bark over the root zone to reduce evaporation and suppress weeds, keeping mulch a few centimetres away from the main stem.

Planting in the ground: site & soil

Choose sun to light shade and avoid spots that stay waterlogged. Improve heavy clay with grit and organic matter; for very sandy soil, add plenty of compost to hold moisture.

Planting in the ground: dig, prep, plant

Dig a hole roughly twice as wide as the rootball and only as deep. Roughen the sides and base, and prepare backfill from topsoil and well‑rotted compost at about 70/30 without strong fertiliser at planting. Soak the potted plant for 10–15 minutes, remove it, tease outer roots, and set the top of the rootball level with the surrounding soil. Backfill and firm in layers, form a shallow watering basin, water deeply with a full can or two, and finish with a 2–3 cm mulch that does not touch the stem.

Spacing & staking (ground)

Allow at least 1–1.5 m of space from walls, fences, or other shrubs for airflow and shape. Most shrubs do not need staking; in very windy sites use a short stake set at an angle with a soft tie during the first season only.

Aftercare (first year)

Water deeply once or twice per week in dry spells, aiming at the original rootball area. Top up mulch each spring and give a light shape once vigorous new growth is visible.

Winter care (UK)

For pots, raise on feet and, in severe frost, move near a wall or wrap the container with fleece or bubble wrap. In the ground, mulch before hard frosts and avoid waterlogging.

Quick troubleshooting

Yellowing leaves usually indicate overwatering or poor drainage; improve drainage and reduce watering. Brown, crispy edges suggest underwatering or wind scorch; water more deeply and add shelter. Leggy growth means the plant needs more light; move to a brighter spot and give a light trim after the main growth flush.
