Planting smaller trees in containers solves many problems. If you have sand or clay soil that would not be good for the tree, you can use top notch, well-draining soil in the container. And if your winters are colder than your tree is hardy, potted evergreen trees winter over well if you can cart the container inside for the cold spells.
But potted trees that survive winter don’t necessarily need to be brought inside. In many areas, it’s entirely feasible to overwinter potted trees outside – including both potted evergreen trees and potted deciduous trees – if you take proper precautions. If you are interested in winter tree protection, read on.
Hey fellow gardeners! I’ve been getting tons of questions about keeping potted trees alive during winter The short answer is yes – trees can definitely survive winter in containers if you give them proper care After years of experience growing trees in pots, I’ll share my complete guide to help your container trees thrive through the cold months.
Why Winter is Tough on Potted Trees
Here’s the thing – trees in pots face bigger challenges than those planted in the ground:
- Limited root insulation from cold temperatures
- Soil temperature fluctuates more dramatically
- Roots are more exposed to freezing conditions
- Container material affects how cold roots get
- Less soil volume to retain moisture and warmth
Choosing the Right Trees for Container Growing
The first step to winter success is picking appropriate trees. Here’s what I recommend:
Cold Hardiness Zones
- Select trees rated for 2 zones colder than your area
- Example: If you’re in Zone 6, choose Zone 4 hardy trees
- This gives extra protection against winter damage
Good Container Tree Options
- Evergreens: Arborvitae, juniper, hemlock, pine
- Deciduous: Maple, birch, oak, beech
- Avoid tropical/subtropical trees unless moving indoors
Best Containers for Winter Protection
The container you choose makes a huge difference! Here’s what works best
✅ Recommended Materials:
- Thick concrete
- Wood planters
- Large containers with more soil volume
❌ Avoid These:
- Plastic pots (poor insulation)
- Metal containers (conduct cold)
- Terra cotta/ceramic (can crack in freeze/thaw)
- Small pots with minimal soil
3 Methods to Overwinter Potted Trees
Method 1: In-Ground Protection
- Dig holes sized for your containers
- Place pots in holes before first frost
- Fill gaps with soil
- Add 2-4 inches mulch on top
- Water occasionally during winter
Method 2: Garage/Shed Storage
- Move pots to unheated but sheltered space
- Maintain temps between 30-40°F
- Check moisture levels monthly
- Limit light exposure (most dormant trees ok)
- Return outside in spring
Method 3: Outdoor Insulation
- Group containers together
- Place larger pots on outside
- Build chicken wire enclosure
- Fill with straw/mulch
- Cover containers completely
Essential Winter Care Tips
Water Management
- Water deeply before ground freezes
- Check soil moisture monthly
- Water when top inch feels dry
- Avoid overwatering (causes root rot)
Fall Preparation
- Stop fertilizing 6 weeks pre-frost
- No heavy pruning late season
- Apply anti-desiccant spray on evergreens
- Move to sheltered spot gradually
Extra Protection
- Wrap pots in burlap
- Use frost blankets during extreme cold
- Monitor weather forecasts
- Be ready to add protection during cold snaps
Special Care for Different Tree Types
Evergreen Trees
- More vulnerable to winter burn
- Need protection from wind/sun
- Regular moisture checks crucial
- Anti-desiccant spray recommended
Deciduous Trees
- More cold hardy generally
- Less winter maintenance needed
- Natural dormancy helps survival
- Focus on root protection
Fruit Trees
- Move citrus indoors if possible
- Extra insulation for peach/plum
- Apple trees usually hardier
- Monitor for rodent damage
Common Winter Problems to Watch For
Keep an eye out for these issues
- Frost heaving (roots pushing up)
- Winter burn on evergreens
- Cracked containers
- Root damage from freezing
- Drought stress
- Animal damage
My Personal Tips for Success
After years of growing trees in containers, here’s what I’ve learned:
- Bigger pots = better survival rates
- Don’t skimp on winter protection
- Group containers for shared warmth
- Monitor moisture levels regularly
- Be prepared for extreme weather
- Start winterizing early fall

Potted Trees That Survive Winter
Trees planted in pots feel the cold of winter more than trees with roots in the ground. That’s because they have less soil insulating their roots. As winter chill sets in, it may be essential to provide winter tree protection to help your tree survive.
This is obviously not necessary for potted trees in warmer climates. For example, in San Francisco, where winter temps stay double digits above freezing, container plants thrive in the back yard all year long without any added winter protection. In cooler regions, potted trees that survive winter are either cold hardy to the region or else are provided protection from cold and wind.
Picking trees that are cold hardy to your location is the first step in helping trees make it through the winter. Keep in mind, however, that hardiness zones reflect the level of cold a tree can survive when its roots are in the earth, not in a container. The roots of your container plants can become colder than those in the ground; in fact, they can drop down to the same temperature as the winter air.
How can you provide these plants with winter tree protection? First, calculate your container’s USDA hardiness zone as two zones colder than your regular zone. That should tell you if your tree is still safe. For example, if you live in Zone 6, choose perennials, trees, and shrubs marked hardy to Zone 4 to increase the chance that the plants will overwinter happily. You’ll also want to pick your containers carefully.
Picking Containers for Potted Trees
The type of container you use can have a big impact on how much cold the tree’s roots will experience. It just makes sense that thin container walls will not shield the cold as well as thicker ones. That eliminates plastic and metal containers for storing potted trees over winter.Gardening tips, videos, info and more delivered right to your inbox!

But there’s more to consider if you have freezing winter weather. Earthenware, ceramic, and terracotta can crack as they freeze or thaw. It’s better to pick concrete or wood containers. And size counts. The bigger the container the better, since it increases the amount of protective dirt surrounding the roots.
How I overwinter shrubs and trees in containers
FAQ
Can You overwinter potted trees outside?
In many areas, it’s entirely feasible to overwinter potted trees outside – including both potted evergreen trees and potted deciduous trees – if you take proper precautions. If you are interested in winter tree protection, read on. Trees planted in pots feel the cold of winter more than trees with roots in the ground.
Do potted trees survive winter?
In cooler regions, potted trees that survive winter are either cold hardy to the region or else are provided protection from cold and wind. Picking trees that are cold hardy to your location is the first step in helping trees make it through the winter.
Can potted plants survive the winter?
Many perennial and evergreen plants in containers can survive the winter, if you take precautions to protect them. Annuals grown in containers are discarded at the end of the season, but many potted perennials, shrubs and small trees can be maintained over the winter if steps are taken to protect the plants and their containers.
Can a container plant survive winter?
If a tree, shrub, or perennial cannot be planted in its final spot before winter arrives, you will need to take steps to make sure it survives the winter while still in the container. Container-grown plants should not be left outdoors above ground over the winter months. Their roots are far less cold hardy than their aboveground parts.
How do you store potted trees in winter?
Here’s another way of storing potted trees over winter. Before the first winter frosts, dig large holes in the garden soil, big enough to accommodate the pots of your container trees. Place the plant’s container into the hole and tuck soil around the edges, water the plants well, then add a thick layer of straw, dried leaves or shredded bark.
Do potted trees feel cold?
Trees planted in pots feel the cold of winter more than trees with roots in the ground. That’s because they have less soil insulating their roots. As the winter chill sets in, you may need to protect your tree for the winter to make sure it lives. This is obviously not necessary for potted trees in warmer climates.
