Frequently Asked Questions

How tall does Thuja Orientalis grow?

Thuja Orientalis typically reaches 3-5 metres in height with a spread of 1-2 metres, making it significantly more compact than many other conifers. Growth rate is moderate at around 15-30cm per year. The naturally columnar habit means it maintains a tidy appearance without extensive pruning, perfect for smaller gardens where space is at a premium.

Is Thuja Orientalis suitable for hedging?

Absolutely! Thuja Orientalis makes an excellent formal hedge or screen. Plant specimens 60-90cm apart for a dense hedge. The naturally upright growth habit creates a neat, architectural screen that requires less frequent trimming than traditional hedging plants. Trim once or twice annually in late spring and late summer to maintain shape.

Can I grow Thuja Orientalis in a container?

Yes, Thuja Orientalis is one of the best conifers for container growing due to its compact size and slow growth rate. Use a large pot (minimum 40cm diameter) with excellent drainage, and fill with a quality ericaceous or multi-purpose compost. Container-grown specimens make stunning focal points for patios, balconies, and formal entrances. Water regularly and feed with a slow-release fertilizer in spring.

Where should I plant my Thuja Orientalis?

Choose a location with full sun to partial shade—at least 4-6 hours of sunlight daily produces the best foliage colour. Thuja Orientalis prefers well-drained, slightly acidic to neutral soil (pH 6.0-7.5) but adapts to most soil types. Avoid waterlogged sites and very exposed, windy locations. Shelter from cold, drying winds helps maintain vibrant foliage.

How do I care for a newly planted Thuja Orientalis?

Water thoroughly after planting and keep the soil consistently moist (but not waterlogged) during the first growing season to establish a strong root system. Apply a 5-7cm layer of mulch around the base to retain moisture and suppress weeds. Feed with a balanced slow-release fertilizer in early spring. Once established, Thuja Orientalis is relatively drought-tolerant but benefits from watering during prolonged dry spells.

When is the best time to plant?

The optimal planting times are autumn (September-November) or early spring (March-April). Autumn planting allows roots to establish during the cooler, wetter months before the following growing season. Spring planting gives the tree a full season to settle in before winter. Avoid planting during frozen or waterlogged conditions.

Does Thuja Orientalis need pruning?

Minimal pruning is required due to the naturally neat, columnar habit. Remove any dead, damaged, or wayward branches in late spring. If growing as a hedge or topiary, trim lightly in late spring (May) and again in late summer (August) to maintain shape. Avoid cutting into old, brown wood as conifers don't regenerate well from bare stems.

Is Thuja Orientalis fully hardy in the UK?

Yes, Thuja Orientalis is fully hardy throughout most of the UK (USDA zones 6-9), tolerating temperatures down to -15°C once established. Young plants benefit from protection during their first winter, particularly in exposed locations. In very cold regions, consider planting in a sheltered spot or providing fleece protection during severe frosts.

What size sapling will I receive?

You'll receive a healthy young sapling, typically 30-50cm tall, carefully selected for vigour and quality. The exact size may vary seasonally. All saplings are grown with care to ensure they establish quickly and thrive in your garden.

Will the foliage change colour?

Thuja Orientalis maintains rich green foliage year-round, though some varieties may develop bronze or golden tints during winter, adding seasonal interest. This is a natural response to cold temperatures and the foliage returns to vibrant green in spring. Ensure adequate watering and avoid exposed sites to minimize winter bronzing.

Are there any pests or diseases to watch for?

Thuja Orientalis is generally robust and pest-resistant. Occasionally, aphids or scale insects may appear—treat with horticultural soap if necessary. Ensure good drainage to prevent root rot, and avoid overhead watering to reduce risk of fungal issues. Healthy, well-maintained plants are naturally more resistant to problems.

How far should I plant from fences or buildings?

Plant at least 1-1.5 metres from fences, walls, or buildings to allow adequate air circulation and room for the mature spread. For hedging, space plants 60-90cm apart. Consider the mature size when planning your planting scheme to avoid overcrowding.

Planting Instructions

1. Dig a hole twice the width of the root ball and the same depth
2. Loosen the soil at the bottom and mix in some compost or well-rotted manure
3. Remove the sapling from its pot and gently tease out any circling roots
4. Place the tree in the hole, ensuring the top of the root ball is level with the surrounding soil
5. Backfill with a mixture of native soil and compost, firming gently as you go
6. Water thoroughly to settle the soil and eliminate air pockets
7. Apply a 5-7cm layer of mulch around the base, keeping it clear of the trunk
8. Water regularly during the first growing season
