One of the easiest ways to maintain the best temperature for your plants is to keep your house warm. With a thermostat, you can easily keep your house cozy and warm without any extra work. On average, houseplants like temperatures of 65 to 75 degrees Fahrenheit. Simply adjust your thermostat so that it falls into this temperature range and let it take care of the rest! It will automatically turn on the heating system in your home so that it stays at the temperature you set it to, keeping your houseplants toasty warm.

Avoid Drafty Locations

While you might enjoy the snowy winter scenery by your window, many houseplants find windowsills far too chilly in winter. To keep your houseplants warm, keep them away from windows or doorways that have cold air drafts. This means that you should also avoid putting a houseplant in your entryways. Every time you open up the door you'll send a blast of icy air over your plants.

Instead, put them somewhere in your home which isn't directly in a cold air draft. For instance, you might have a great coffee table or fireplace mantel in your living room that gets sunlight but isn't right next to your frozen windowpanes.

Put Them in a Sunny Room

Another easy way to ensure your plants are cozy in the winter is to relocate them to a sunny room. When the sun shines in on a bright winter day, it will naturally warm up your room without using your heating system. This is a great way to save on energy too!

A good way to find out how warm the room actually gets is to place a thermometer where you plan to put your houseplants. Then, check the ambient room temperature on a sunny winter day. If it stays in the range of 65 to 75 degrees Fahrenheit, this will keep the average houseplant comfortable.

Keep in mind that not all plants love a lot of sunlight, some plants do best in low light. So a sunny room isn't a solution for every plant. Check the light requirements of each plant before placing it in the sunny room. If you notice the foliage on your plant is fading or the leaves are burning with brown tips, it could be receiving too much light.

Heat Mats

Heats mats can be a handy way to warm a selection of houseplants. Generally, heat mats are a great choice if you just have a few indoor plants that you want to keep warm. Essentially a heat mat is a flat mat that you plug into an electrical outlet. You then set the heat mat to a specific temperature. They provide a steady source of heat for plants and are also a popular option for germinating seeds indoors.

Note: If you choose this option, check to see if all the plants you will be putting on the heat mat like the same temperature range. You may find this is best for just those houseplants which consistently need higher temperatures than the ambient heat in your home.
