Bringing Plants Indoors For Winter
For Zone 5 & 6 gardeners, late September and early October is the time to think about bringing those plants you can’t live without indoors for the winter. Here are some practical tips to make sure your plants stay happy and healthy inside your home until next spring …
Of course, annuals can be discarded once they’ve lived out their seasonal lifespan. Impatiens, zinnias, petunias and other annuals that are easy to obtain can be disposed of once their time is finished …
Take It Slow
For the plants you want to save, acclimate them slowly to their indoor winter environment. We’ve always had better luck by bringing plants indoors when there’s still daytime warmth and when nighttime temperatures aren’t dipping below 50 degrees consistently, say 4-5 days in a row.
Make sure plants that need full sun are placed in a sunny window. It’s best to be realistic in this regard. You might have to choose between plants if you don’t have adequate sunny space to meet their needs …
We like to keep windows open, or at least cracked open, whenever possible until colder temperatures make it impractical. Plants will adapt much better to an indoor space if they are gradually weaned off fresh air from outside.
Fertilizing During The Winter
Plants need a rest period from their blooming cycle, and winter is the perfect time to let them rest. A good rule of thumb is not to fertilize at all for 5-6 months. In Zone 5, this is typically mid October through mid March. You can water your plants when they dry out, but be careful not to over water. You will likely have to monitor your plants more closely because indoor environments tend to be much dryer, especially in late fall and winter when the heat is on.
Be Sure To Remove Insects
One key task that is often ignored is making sure your plants aren’t harboring any insects from outside. Certain insects may not be visible to the naked eye, but if they’re present on your outdoor plants, they can cause great harm by spreading to your other indoor plants.
We recommend using an organic insect killer spray that is proficient at ridding your plants of a wide variety of pests. Spray the plants thoroughly per the directions and you’ll avoid dealing with a winter insect epidemic …
All in all, you should be able to successfully transition many of your favorite plants through the winter by bringing them indoors. Sometimes, plants won’t survive, but if you follow these tips your favorites should do quite well until the temperatures warm up again in the spring.
