Wait, Do You Need to Bring Potted Plants Inside for Winter?

As temperatures begin to fall and frost sets in, many plant owners wonder what to do with their outdoor potted plants. Should every plant be moved indoors, or are some hardy enough to survive winter on the patio? The truth is that care needs vary widely depending on the plant type, container, and climate. Understanding these differences helps protect your greenery from cold damage and ensures a thriving garden in spring.

Why Potted Plants Are More Vulnerable to Cold

Unlike plants rooted in the ground, potted plants lack the natural insulation provided by surrounding soil. Containers expose roots to freezing temperatures more quickly, making many plants susceptible to frost damage. When the root ball freezes, the plant can no longer absorb water or nutrients—leading to winter kill.

This is why gardeners recommend evaluating each plant before deciding whether it should overwinter indoors.

Plants That Should Be Brought Inside

Not all plants can tolerate freezing temperatures. The following categories are the most sensitive and should be moved indoors well before the first frost.

1. Tropical Plants

Plants like hibiscus, ferns, palms, elephant ears, and crotons cannot survive below 10–15°C. Bringing them indoors prevents leaf drop, rot, and severe shock.

2. Tender Perennials

Perennials such as geraniums, coleus, and begonias may survive in warmer climates but struggle in colder regions. Overwintering them indoors keeps them alive for replanting next year.

3. Houseplants Summered Outdoors

Plants like pothos, philodendrons, snake plants, and peace lilies that spent the summer outside should always be brought back inside once temperatures hit 10°C at night.

4. Herbs Sensitive to Frost

Basil, parsley, mint, and cilantro can be kept alive indoors with adequate light. Once frost hits, outdoor herbs decline quickly.

Plants That Can Stay Outside

Some plants are naturally built to withstand winter weather—even in containers.

1. Hardy Perennials

Plants like hostas, coneflowers, and black-eyed Susans will survive outdoors if the pots are insulated or placed against a sheltered wall.

2. Evergreen Shrubs in Containers

Dwarf varieties of juniper, boxwood, and arborvitae tolerate cold well. Still, they benefit from mulching and occasional watering during dry winter periods.

3. Cold-Tolerant Herbs

Thyme, sage, and rosemary (in mild climates) can remain outside with minimal protection.

How to Safely Transition Plants Indoors

Gardeners recommend these steps for a smooth transition:

• Inspect for pests before bringing plants inside. Wash leaves and treat soil if necessary.

• Reduce watering—indoor winter conditions require less moisture.

• Provide adequate light, ideally near a bright window or under grow lights.

• Acclimate gradually by bringing plants inside at night for a few days before moving them permanently.

This process helps reduce stress and prevents leaf drop from sudden environmental changes.

Protecting Outdoor Plants Left in Pots

If you choose to overwinter certain plants outside, gardeners suggest:

• Wrapping pots with burlap, bubble wrap, or insulating fabric

• Moving containers close to the house for warmth

• Elevating pots to improve drainage

• Adding a layer of mulch around the base

Taking these steps minimizes freeze damage and keeps roots healthy.

Conclusion

Whether you should Bring Potted Plants Inside for Winter depends on the type of plant, its hardiness, and your local climate. Tropical and tender plants must be protected indoors, while hardy perennials and evergreens can often remain outdoors with proper insulation. By understanding each plant’s needs and preparing them early, you can safeguard your container garden and enjoy lush, healthy growth in spring.
