Bringing Summer Houseplants Back Indoors for Winter

When temperatures begin to dip in fall, it’s time to think about transitioning your houseplants back inside for winter. At Sunnyside Gardens, we keep a close eye on overnight lows—most tropical plants, houseplants, and summer annuals begin to struggle once temperatures fall below 45°F.
If your houseplants spent the summer outdoors on patios, porches, or in container gardens, early fall is the time to help them make a smooth move indoors. With a few simple steps, these plants can continue to thrive all winter long.
What You’ll Need Before Bringing Plants Inside
Before you start the transition, gather a few essentials:
- A bright, sunny window
- A clean pot with drainage
- Fresh, high-quality potting mix
These basics will set your plants up for success during the lower-light winter months.
3 Essential Tips for Transitioning Houseplants Indoors
1. Choose a Bright, Sunny Location
As daylight shortens, indoor light levels are significantly lower than what plants experience outdoors. Once inside, plants naturally slow their growth, may drop a few leaves, and require less water and fertilizer. This is completely normal.
Place plants near the brightest window you have—south– or west-facing windows are ideal. Don’t be alarmed if your plant looks a little different than it did outside; it’s simply adjusting to its winter environment.
2. Refresh with New Potting Mix
Repotting with fresh potting mix is one of the best things you can do when moving plants indoors. New mix provides gentle nutrients that last through winter and improves drainage and airflow around roots.
Avoid: Garden soil, manure, or topsoil, which can introduce pests and hold too much moisture. A quality indoor potting mix helps prevent common winter issues like root rot and fungus gnats.
3. Use the Right Pot
A good pot makes all the difference during winter months. Look for one that:
- Allows room for the roots to grow
- Has a drainage hole to prevent soggy soil
- Includes a saucer to protect surfaces and catch excess water
Proper drainage is especially important when plants are growing more slowly and using less water.
Bonus Tip: Check for Pests Before Bringing Plants Inside
Before your plants cross the threshold indoors, inspect them carefully for pests. Look under leaves and along stems, and rinse foliage if needed. Starting a simple preventative routine now can help avoid unwanted insects throughout winter.
