Many plants are hardy enough to bloom right through winter. Garden Centers are stocked full of these winter bloomers like Kale, pansy, viola, snapdragons, and more.

Frosty nights does not mean the end of your summer container plants filled with ferns, geraniums, begonias, and impatiens. Although these do not survive the winter, they can be brought indoors as houseplants.

How Do You Decide Which Tender Plants To Bring Indoors?

Although it’s tempting to move every plant indoors, it is impractical. You and the plants will fare much better if you run through the following checklist and keep only the plants that meet these criteria.

1. Keep only healthy plants. If something has been struggling all summer under the best of conditions, it is not going to improve indoors. Time to face the compost.

2. Never bring in a plant with pests or disease indoor. Don’t try to convince yourself that you’ll quarantine the plant until it’s been coaxed back into health. Problems spread quickly when plants are indoor. There are no natural predators of insects in the house, and indoor conditions can be ideal for a disease to spread.

3. Give dibs to your favorite plants, and those you’ve been coddling for years, like a bay tree. Also, anything you’ve trained into a standard tree, sentimental favorites, and expensive splurges if you have the room.

4. If the plant would look suitable as a houseplant, bring it in and use it. Many people have the light to successfully winter geraniums, fuchsia, begonias, even passion flower, in full bloom. It’s nice to have something blooming through winter. These snowbirds will be ready to start blooming outdoors early next spring.

5. You might consider bringing in smaller pepper or tomato plants. These are tropical perennials and, given enough light, continue to produce fruits indoor. Tomatoes need a large pot. You’ll have more success growing a compact, patio variety. Cherry tomatoes and small-fruited peppers like chilies or cherry varieties fruit easiest and produce higher yields indoor. Keep in mind that there are no insects or gentle breezes inside to pollinate your plants. That will be up to you.

Before you Bring the Outside In 

Clean and Pick off spent flowers and dead or damaged leaves. This is the time to cut back each plant that will winter with you so they fit in your home better.

Spray the remaining foliage with ‘Triple Action‘ to eliminate insects and kill spider eggs. You don’t want to bring these pests indoors, trust me.

Water the soil thoroughly to flush as many worms, grubs, gnats, earwigs, and bugs out of the soil. The apply ‘Systemic Granules‘ to eliminate all remaining insects. You really don’t want worms crawling across the carpets.

Feed Indoor plants monthly with my specially formulated ‘Flower Power.’ This is especially true for plants brought from the outdoors.

  1. Great inspiration for wintering over my begonias. Wish me luck. Nothing ventured nothing gained. I have set up a table with timered grow lights as the days grow shorter. I brought in my flower boxes. Trimmed the flowers and will tend to them until May, unless they don’t make it.
    Thanks for the info. Hope to visit Prescott ,

    1. Thanks. Usually, by Mid-March the Garden Center is in full Spring Mode.
