- Dig a hole about twice the width of the root ball and approximately the same depth.
- Place the arborvitae in the hole so the top of the root ball sits level with the surrounding soil.
- Backfill with soil and gently firm the soil around the roots to remove air pockets.
- Water thoroughly after planting to help the soil settle around the root system.
- Apply 2–3 inches of mulch around the base of the tree to help retain moisture and regulate soil temperature.
Keep the mulch a few inches away from the trunk so the bark can breathe and prevent excess moisture buildup.
- For privacy hedges, plant trees about 5–6 feet apart so they grow together into a full natural screen.
Spacing Options
Spacing can vary depending on the type of hedge you want to create:
- 5–6 ft apart → fast privacy screen (most common)
- 6–8 ft apart → balanced growth with strong individual trees
- 8–10 ft apart → more open spacing, ideal for large landscapes
- Some landscapers also plant trees in a zig-zag pattern for wider screening areas
Choosing the right spacing depends on how quickly you want the hedge to fill in and how much space you have available.
During the first growing season, water regularly so the root system can establish properly.
Once established, Green Giant Arborvitae becomes very resilient, but it will grow fastest and healthiest with consistent moisture.
Simple Watering Rule of Thumb
Check the soil before watering.
- If the soil feels muddy, soggy, or sticky, the plant has enough water — do not water yet
- If the soil feels slightly moist, watering can usually wait another day or two
- If the soil feels dry or firm, it is time to water
Quick Soil Check
Insert a finger, stick, or small tool about 2–3 inches into the soil.
- If it comes out wet with mud, wait before watering
- If it comes out slightly damp, the soil still has moisture
- If it comes out dry, give the plant a good watering
Best Time to Water
The best time to water is early morning, which allows the soil to absorb moisture before the heat of the day.
Watering in the late afternoon or evening is also fine if needed. Avoid watering during the hottest part of the day, when water evaporates quickly.
Soil Considerations
Green Giants are adaptable, but soil conditions can affect watering needs.
- Clay soils hold water longer and may require less frequent watering
- Sandy soils drain quickly and may require more frequent watering
- Soil fertility and drainage vary by location
If your soil is very sandy, clay-heavy, or compacted, it may help to research local planting recommendations or improve soil conditions if needed.
---Seasonal Care Tips---
Summer Care 🌞
During hot summer months, Green Giants may require more frequent watering, especially during dry periods.
- Check soil moisture regularly
- Deep watering is better than frequent shallow watering
- Mulch helps keep roots cool and retain moisture
Green Giants are fast growers, so proper watering during summer helps maximize growth.
Winter Care ❄
Green Giant Arborvitae is highly cold hardy and more resistant to winter stress than many other arborvitae.
- Foliage may slightly darken or bronze during very cold weather
- This is a normal seasonal response and not a cause for concern
Before the ground freezes, it can help to water deeply once more so roots enter winter with adequate moisture.
Young trees may benefit from some protection in very windy or exposed areas during their first winter.
To reduce shipping weight and help plants travel safely, some plants may be shipped without their nursery pot. The root system is still protected with soil and moisture-retaining wrapping so plants arrive in good condition and ready for planting.
Plants are carefully prepared, bundled, and packaged to help maintain moisture during transit. Roots typically arrive moist and healthy. For best results, plants should be planted as soon as possible after delivery.
If you are unable to plant immediately, place the roots in soil and keep them lightly watered until you are ready to plant. This is especially helpful for larger orders that may be planted over the course of a few days or weekends.
Because plants are living products, size, fullness, and moisture level may vary slightly depending on season and stage of growth.
