If you’ve been wondering whether it’s possible to grow arborvitae from seeds, the short answer is yes, it is.
Growing arborvitae from seeds is a rewarding project, though it takes longer than buying established plants.
Many gardeners enjoy the process of growing arborvitae from seeds because it’s cost-effective and deeply satisfying.
In this post, we’ll walk through exactly how to grow arborvitae from seeds, from seed collection to transplanting.
Let’s dig into everything you need to know about growing arborvitae from seeds.
Can You Grow Arborvitae From Seeds Successfully?
Yes, you can absolutely grow arborvitae from seeds successfully.
The key is understanding the natural dormancy of arborvitae seeds and how to break it.
Arborvitae seeds have a hard outer coat that needs cold stratification before they will sprout.
Without that cold treatment, your arborvitae seeds may never germinate.
Still, once you provide the right conditions, growing arborvitae from seeds is very doable.
1. Harvest or Purchase Fresh Arborvitae Seeds
To grow arborvitae from seeds, start with high-quality seeds.
You can collect seeds from mature cones in late summer or early autumn.
Look for cones that are brown and slightly open.
Place the cones in a paper bag to dry for a few days until the seeds fall out.
Alternatively, buy stratified arborvitae seeds from a reputable supplier.
2. Cold Stratification Is Essential for Arborvitae Seeds
Arborvitae seeds must experience a cold, moist period to mimic winter.
This process is called cold stratification and lasts about 30 to 60 days.
Mix arborvitae seeds with damp sand or vermiculite inside a sealed plastic bag.
Store the bag in your refrigerator at 34–41°F (1–5°C).
Check periodically to ensure the medium stays moist but not soggy.

3. Sow Stratified Arborvitae Seeds in Spring
After stratification, your arborvitae seeds are ready to sow.
Fill seed trays with a well-draining potting mix.
Press the arborvitae seeds gently into the soil, barely covering them with a thin layer.
Water lightly and place the tray in a bright location out of direct sun.
Keep the soil consistently moist but not waterlogged.
What Conditions Help Arborvitae Seeds Germinate?
Arborvitae seeds germinate best under specific conditions.
Even if you’re actively growing arborvitae from seeds, poor conditions can stop germination.
1. Consistent Moisture for Arborvitae Seeds
Arborvitae seeds need steady moisture to swell and sprout.
Water the seed tray gently with a spray bottle to avoid displacing seeds.
Cover the tray with a clear plastic dome or plastic wrap to retain humidity.
Remove the cover once seedlings appear to prevent mold.
2. Warmth Speeds Up Germination of Arborvitae Seeds
After cold stratification, arborvitae seeds require warmth.
Aim for soil temperatures between 65–75°F (18–24°C).
Using a propagation heat mat can help maintain steady warmth.
Under these conditions, arborvitae seeds usually germinate in 2 to 4 weeks.
3. Bright, Indirect Light for Arborvitae Seedlings
Once arborvitae seeds sprout, they need plenty of light.
Place the tray near a south-facing window or under grow lights.
Give seedlings 12–16 hours of bright light each day.
Rotate the tray occasionally so all growing arborvitae from seeds stay straight.
How to Care for Young Arborvitae Grown From Seeds
After germination, your arborvitae seedlings need careful attention.
Growing arborvitae from seeds into strong plants takes time and consistency.
1. Transplanting Arborvitae Seedlings to Larger Pots
When arborvitae seedlings have two sets of true leaves, transplant them.
Use small individual pots with drainage holes and quality potting soil.
Handle the fragile arborvitae seedlings by their leaves, not stems.
Water gently after transplanting and keep them out of harsh sun for a few days.
2. Hardening Off Arborvitae Grown From Seeds
Before moving arborvitae seedlings outside, harden them off gradually.
Set them outdoors in a sheltered spot for a few hours each day.
Increase time outside over one to two weeks.
This process helps your arborvitae seeds’ offspring adjust to wind and sun.
3. Planting Outdoors and Long-Term Care
Choose a site with full sun to partial shade and well-drained soil.
Space your arborvitae plants according to the mature size of the variety.
Water deeply during the first year to encourage deep roots.
Mulch around the base to retain moisture and suppress weeds.
