Practical Houseplant Care During Heating Season

In many parts of the United States, we are deep into heating season and spending much of our time indoors. Whether we use oil, gas, electric or wood to stay warm, the heated air in our homes can become bone dry as winter wears on.

We humans acutely feel the loss of moisture in our skin, hair and mucous membranes as humidity levels drop, but don’t forget that our houseplants crave moisture as much as we do. So, how do we keep our plants (and ourselves) healthy and happy in this arid environment? The following are some simple and practical tips to help raise the humidity in our homes to a more comfortable level:

WATER PLANTS THOROUGHLY

The simple act of watering plants is the easiest way to put moisture back into the air of our homes, but just giving your plants a halfhearted passing splash is not going to do the trick. When watering, try to use the ‘drench and drain’ method. By this I mean to water a plant thoroughly, preferably in a sink or tub, where the water can generously run through the potting medium and out the drainage hole(s). Allow the pot to drain completely before returning the plant to its usual home. Alternatively, you can place your potted plant in a bowl of tepid water for an hour or so while it soaks up what it needs. Your houseplant’s pot will feel heavy with moisture after you do this and will keep your plant hydrated for a longer period of time. When the pot feels light again, it’s time to water thoroughly!

AIR DRY YOUR LAUNDRY

Whenever possible, hang laundry around your house or apartment to air dry rather than use a clothes dryer. The damp clothes will not only dry surprisingly fast indoors but will replace much-needed moisture in the rooms where they are placed. I like to utilize bathroom shower rods, towel racks and over-the-door clothes hangers for this purpose. Foldable clothes drying racks are also easy to store and convenient for indoor winter use!

UTILIZE BATHROOM STEAM

We Americans love to shower, so why not leave the bathroom door open while showering or bathing to allow that health-giving steam to escape and disperse into your living space. Many plants thrive in these typically humid rooms so, if space allows, you might move some plants into the bathroom for the winter months; just be sure there is adequate light from a window or LED fixture.

TAKE ADVANTAGE OF WARMER DAYS TO OPEN UP

Baby, it’s cold outside! But not all winter days are dry and frigid. On cloudy or rainy days, when outside temps are above freezing, try cracking open a window or two to circulate the air for a little while. Be sure to move any plants away from the windows so that the colder air won’t be blowing directly on them. The natural humidity and fresh air will not only help your home feel instantly more comfortable, it will also cheer your winter-weary soul!

POLLY PUT THE KETTLE ON

Heating water in a kettle on a woodstove or kitchen range and letting the steam escape into the air works pretty much in the same way as a humidifier. Making stovetop winter soups and stews helps, too! If you’re fortunate to have a bright kitchen windowsill, any plants placed there will also benefit from the extra moisture given off by daily washing and cooking.

HUMIDITY TRAYS AND HUMIDIFERS

Humidity trays are easily created using a flat baking sheet or even a single plant saucer. The idea is to use pebbles or flat stones to cover the tray or saucer bottom, add water to fill, and then place your plants atop the pebbles so that they don’t sit directly in the water. As the water in the tray or saucer slowly evaporates, your plants will enjoy that extra moisture!

If your home is extremely and persistently dry, or if you suffer from allergies or respiratory issues, a good quality humidifier will certainly help. These are a great way to direct humidity where you need it most such as in bedrooms and nurseries or near tropical orchids, African violets, ferns and other moisture-loving plants. The downside is that humidifiers can quickly grow mold so be sure to keep your unit clean as per the manufacturer’s instructions.

Bringing the Greenery Back Inside

Now that temperatures are falling, many of us are in the process of bringing in potted plants from outdoors.  Some will do well inside our homes, others not so much, but it’s always fun to try and save them for another year.  Surrounding ourselves with green plants helps cheer us through the dark winter months and adds much-needed moisture to the dry air in our homes.  Today, I’ll focus on potted tender houseplants as well as potted hardy perennials and how to care for them through the winter months.  Here are some of my tips for bringing the greenery back inside.

SEQUESTER AND WASH TENDER PLANTS FIRST

All those houseplants you moved outdoors in June really enjoyed their summer vacation but they may have picked up some unwanted hitchhikers along the way.  Once you bring them inside, place the plants in your kitchen sink (or your shower for the big guys) and use a sprayer to wash off all the leaves.  Be sure to spray well underneath the leaves where insects and eggs can hide.  Water the soil thoroughly, too, and let the pots drain completely.  This will help wash away any insects.  Also, giving your plants a thorough soaking will help them adjust to their new dry heat environment.  If you can, group these plants together for a few days and monitor for any disease or insects BEFORE you let them join in with your other houseplants.

CREATE SPACE AND LIGHT FOR TENDER PLANTS

This sounds easier than it actually is because now you have a bunch of plants that need a home for several months and that home has to provide enough light.  Unless you are fortunate enough to have a bright, sunny room specifically for your plants, creating such a space can be a challenge.  Certain plants like herbs, for example, need as much sunlight as possible to thrive indoors and winter sunlight can be hard to come by.  Also, your resident houseplants (those you don’t move outside) have probably already taken the sunniest spots on your windowsills.  The good news is that plants are social and love hanging out with their neighbors, so feel free to group them closely together and encourage a plant party wherever you can find the space.

One trick I’ve learned to create more light indoors is to use LED plant light bulbs in my regular house lamps and group as many plants as possible underneath.  These light bulbs are inexpensive to buy and use, are longlasting and fit in a standard socket.  Your plants will benefit not only from the extra light of the plant bulb but grouping the plants together will help sustain the moist environment they crave in the dry winter heat of our homes and may make the difference between just surviving and thriving.

USE COLD STORAGE FOR POTTED PERENNIALS

During the summer I like to use potted perennials like hostas, heuchera, lamium, ferns, and creeping Jenny to add color to the many shady nooks around my home.  After a killing frost, I take those big planters and keep them over the winter in my unheated garage.  This accomplishes two important things.  I don’t have to worry about my pots getting damaged from the constant freezing and thawing going on outside and the unheated garage provides the perfect place for these plants to achieve the winter dormancy they require while in a protected environment.

The crucial thing to remember here is that your plants will need water to survive in this dry, cold space.  Check them every couple of weeks and keep a watering calendar to remind you when it’s time to look in on them.  Water them sparingly but regularly, just enough to keep them moist.  It’s better to err on the dry side here as too much water will only cause them to rot.  In early spring you’ll notice fresh green growth, the sure sign that you have done your job well.  Continue to water and move your pots outside again in the spring after danger of frost has passed.

By assessing your plants’ needs and creating mini-environments of adequate light and moisture, your houseplants will be happier and healthier.  Your potted perennials, on the other hand, will sleep peacefully through the winter, thinking they’re safely tucked under a blanket of snow.  In either case, they should all arrive safely at their spring destination where they can enjoy the great outdoors once again!
