Plants That Should Go Inside for the Winter<\/strong><\/h2>
\u201cMany potted plants can easily be overwintered indoors as houseplants,\u201d says Diane Larson, a horticulturist at Rutgers Cooperative Extension of Monmouth County, N.J. Larson recommends bringing all tropical plants indoors for the winter. They include: <\/p>
- Calla
<\/li> - Canna
<\/li> - Ginger
<\/li> - Gladiolus
<\/li> - Palms
<\/a><\/li>- Citrus<\/li> <\/ul>
Other plants that should go inside during the winter months include:<\/p>
- Hibiscus
<\/li> - Pelargonium (better known as geraniums)
<\/li> - Begonias
<\/li> - Mandevilla
<\/li> - Oleander
<\/li> - Caladium
<\/li> - Angel\u2019s trumpet
<\/li> - Succulents
<\/a><\/li>- Coleus
<\/a><\/li>- Herbs<\/a>: Parsley, basil, rosemary, and mint can survive inside during cold weather.<\/li> <\/ul>
Pro Tip: <\/strong>If you don\u2019t have room to store your perennials indoors or in a greenhouse<\/a>, buy plants that can withstand your area\u2019s average low winter temperatures.<\/p>
Plants That Can Survive Winter Outside<\/strong><\/h2>

Photo Credit: Pixnio<\/a><\/figcaption><\/figure> Other plants, with proper care, can stay outdoors<\/a> during winter. They include:<\/p>
- Japanese yew and Brown\u2019s yew<\/strong> can dress up a front porch year-round. They\u2019re drought-tolerant, cold-hardy, and like both full sun and partial-sun settings.
<\/li>- Potted blue spruce<\/strong> is a popular evergreen that\u2019s often raised as Christmas trees. It needs full sunlight, and the soil must be kept damp. Just be sure the pot has a drain hole so you won\u2019t overwater it.
<\/li>- Cypress topiaries<\/strong> need morning light and afternoon shade. You also have to make sure not to overwater, or they will rot.
<\/li>- Boxwood hedges, English boxwoods, and winter gem boxwoods<\/strong> are shaped like topiaries and need full sunlight to survive harsh winters. The rule regarding watering boxwood shrubs<\/a> is once to twice each week.
<\/li>- Violas<\/strong> are tough enough to withstand snow, and will produce flowers over the winter. The trick is to keep them in a pot with good drainage. To keep violas<\/a> flowering, snip off the heads once the flowers fade.
<\/li>- English primrose<\/strong>, which comes in many colors, just gets going in the winter. It can take full sun when it\u2019s cold, but make sure you water English primrose<\/a> regularly. <\/li> <\/ul>

Containers that work well in winter weather:<\/strong><\/p>
\u2713 Fiberglass<\/p>
\u2713 Iron<\/p>
\u2713 Stone<\/p>
\u2713 Concrete<\/p>
\u2713 Heavy plastic<\/p>
Containers that DON\u2019T work in winter weather:<\/strong><\/p>
\u2717 Terra cotta <\/p>
Why terra cotta doesn\u2019t work well in winter:<\/strong> Its water-absorbent nature causes it to freeze repeatedly and eventually crack.
<\/p>\u2717 Ceramic pots <\/p>
Why ceramic doesn\u2019t work well in winter:<\/strong> Any chips in the glaze can let in water.<\/p>
\u2717 Hanging baskets <\/p>
Why hanging baskets don’t work well in winter:<\/strong> They dry out quickly and don\u2019t insulate roots well.<\/p>
Other Ways to Protect Your Outdoor Plants<\/strong><\/h3>
Don\u2019t overwater:<\/strong> Make sure your soil is well-drained. Because your plants won\u2019t grow much in cold weather, avoid allowing the roots to be cold and damp for a long time. That\u2019s a recipe for root rot .Don\u2019t leave the pots in saucers; water can collect and freeze. <\/p>
Protect the roots<\/strong>: Keeping heat and moisture around the roots will help the plant survive. Some ways to do that are:<\/p>
- Use a bigger pot.<\/strong> This will increase the soil insulation around the roots.
<\/li>- Wrap the pot.<\/strong> Burlap and bubble wrap are good choices.
<\/li>- Bury the pot.<\/strong> Dig a hole<\/a> in your garden, place the pot in the hole, and cover with soil or mulch<\/a>. <\/li> <\/ul>
When to Bring Plants Inside for Winter<\/strong><\/h2>
If you plan on bringing plants inside, late fall is the time to pay close attention to the weather. While your local weather report will warn you of an impending frost or freeze, it\u2019s best to avoid a last-minute rush to winterize and\/or move your plants. So, how do you winterize<\/a> your plants?<\/p>
One way is to know what temperatures your plants will tolerate. The USDA Plant Hardiness Zone Map<\/a>, based on the average annual minimum winter temperatures within a state, will help you determine which plants are most likely to thrive in your area. <\/p>
When will that first frost hit?<\/strong> That can be tricky, since frost can hit some areas and not others. According to the National Weather Service<\/a> (NWS), frost is more widespread when temperatures drop below 32 degrees. When temperatures fall below 28 degrees, a hard freeze is more likely. <\/p>
To get a better idea of conditions in your area, the NWS offers local frost and freeze information on its website. <\/p>
How to Store Outdoor Plants Inside<\/strong><\/h2>
Once you\u2019ve moved your potted plants inside, your task is to keep them safe until spring. Some precautions to take:<\/p>
- Let the plants acclimate. <\/strong>Allowing your plants to settle in a garage<\/a> or an all-seasons room lets them adjust to changes in humidity and temperatures.
<\/li>- Give them light and warmth.<\/strong> Don\u2019t leave your plants in an unheated garage or shed, though they should be fine in a room with temperatures ranging from 55 to 70 degrees Fahrenheit. And while your plants need the same light levels as they received outside, keep them away from drafty windows.
Pro Tip: <\/strong>A grow light can help if your house doesn\u2019t have enough natural indoor light.<\/li> <\/ul>- Keep them away from pets.<\/strong> Some plants are toxic<\/a> to animals. And ingesting any plant can possibly bring on an upset stomach. So keep your plants out of reach of a curious taster \u2014 or climber. See our article on 28 Plants Poisonous to Dogs<\/a> for more information.<\/li> <\/ul>
<\/strong>How to Keep Plants Healthy Indoors<\/strong><\/h3>
Start with healthy plants.<\/strong> Does it look spent? Are the leaves or the soil infested with pests? If so, it may be best to let it go. <\/p>
But don\u2019t worry if your plant loses its leaves once it\u2019s inside. \u201cIt just means they are going dormant or adjusting to the lower light conditions and may sprout new leaves that are more acclimated to the site,\u201d Larson says. <\/p>
Don\u2019t overwater.<\/strong> Once inside, your plants won\u2019t need as much water, and a root system sitting in too much water will rot. Only water when the soil surface is dry to the touch.<\/p>
How to Keep Plant Pests Outside<\/strong><\/h3>

Photo Credit: Lincoln Peh<\/a> \/ Wikimedia Commons \/ CC BY 2.0<\/a><\/figcaption><\/figure> To avoid a pest infestation that can spread to all your indoor plants, be sure to check your overwinter plants for leaf- and soil-dwelling insects. Some pests to look for:<\/p>
Leaf-dwelling pests:<\/strong><\/p>
- Aphids
<\/a><\/li>- Spider mites
<\/a><\/li>- Scale mealybugs
<\/a><\/li>- Gnats
<\/li>- Spiders
<\/li>- Lacewings
<\/li>- Whiteflies<\/li> <\/ul>
Soil-dwelling pests:<\/strong><\/p>
- Slugs
<\/li> - Sowbugs
<\/li> - Earwigs
<\/li> - Fungus gnats
<\/li> - Ants<\/a><\/li> <\/ul>
The easiest way to remove leaf-dwelling insects is to gently spray the tops and undersides of leaves with water.<\/strong> (You should do this even if you don\u2019t see insects, just to stay on the safe side. You don\u2019t want to bring pests indoors.). If you still see insects after spraying with water, apply an insecticide and keep the plant under quarantine.<\/p>
For soil-dwellers, just flick them off with your fingers. If you still see insects, apply insecticide on the soil surface and around the pot\u2019s drainage hole.<\/p>
How to Return Plants Outside Come Spring<\/strong><\/h2>
Once the risk of frost has passed, and nighttime temperatures stay above 45 degrees, it\u2019s time to take your plants outside. Start by placing the plants next to your house in a somewhat shaded space and gradually move them to brighter areas in your yard. <\/p>
As temperatures warm up, be sure to water accordingly. Soon, your plants will give you another season of summer colors.<\/p>
FAQ<\/h2>
How Do I Know if a Pot Allows Good Drainage?<\/strong>Simply check the drainage hole in the pot to make sure it\u2019s not clogged with rocks, debris, or mineral buildup. Clean if needed. Don\u2019t place rocks or gravel in the bottom of a plant pot, as they can hinder drainage.<\/p> <\/div>
Can I Cover Outdoor Plants?<\/strong>If you are establishing anew plants or have a winter garden, a cover can protect them from extreme temperatures or snowfall. Landscape fabric<\/a>, bed sheets, and tablecloths are all good choices for covers. You can also buy row cover fabric from a local home and garden store or online.<\/p> <\/div>
When Should I Repot My Plants?<\/strong>While it\u2019s good to replace the potting soil occasionally, it doesn\u2019t have to be done every year. Generally, you can just remove and replace the top third of the mix. Definitely replace the soil if the plant has had an insect problem, and clean the container with a bleach solution.\u00a0<\/p> <\/div> <\/div>
