Thuja Oriental Live Plant

Caring for and growing a Thuja plant (Arborvitae) indoors is definitely possible — especially with dwarf or compact varieties — but it does require a bit of attention since Thuja naturally prefers outdoor conditions.

🌿 1. Choose the Right Variety

For indoor growing, pick a dwarf or compact Thuja, such as:

• Thuja occidentalis ‘Danica’ (small, globe shape)
• Thuja occidentalis ‘Smaragd’ (Emerald Green Arborvitae) – slow-growing and tidy
• Thuja plicata ‘Atrovirens’ – tolerates low light a bit better

These varieties are easier to manage indoors and won’t quickly outgrow your pot.

☀️ 2. Light Requirements

• Needs bright, indirect sunlight. Place it near a south- or west-facing window where it can get at least 6 hours of light daily.
• If natural light is weak, use a full-spectrum grow light for 10–12 hours per day.
• Rotate the pot every week to keep even growth.

💧 3. Watering

• Thuja prefers consistently moist (but not soggy) soil.
• Water when the top 2–3 cm (1 inch) of soil feels dry.
• Make sure your pot has good drainage holes — standing water can lead to root rot.
• In winter, water less often but don’t let it dry out completely.

Tip: Mist the foliage occasionally or place a humidity tray nearby to prevent brown tips in dry indoor air.

🌱 4. Soil

• Use well-draining potting soil — a mix of:
  • 2 parts peat or coco coir
  • 1 part perlite or sand
  • 1 part compost or pine bark
• pH should be slightly acidic to neutral (6.0–7.5).

🌡️ 5. Temperature and Humidity

• Ideal temperature: 15–25°C (59–77°F).
• Avoid placing near heaters, air conditioners, or cold drafts.
• Likes moderate humidity — 40–60%.

🌾 6. Fertilizing

• Feed once a month in spring and summer with a balanced, slow-release fertilizer (e.g., 10-10-10).
• Stop fertilizing during fall and winter when growth slows down.

✂️ 7. Pruning & Maintenance

• Lightly trim to shape in spring or early summer.
• Remove brown or dead tips to encourage new growth.
• Avoid heavy pruning into old wood — Thuja may not regrow from that.

🪴 8. Repotting

• Repot every 2–3 years or when roots start to fill the pot.
• Move to a pot 1 size larger with fresh soil.
• Best time: early spring.
