Caring for Your Houseplants in Winter
Indoor plants have greatly increased in popularity over the last few years. As the weather changes in the coming winter months, the needs of our indoor plants change as well.

The biggest change for indoor plants in the winter is lower light levels. Many of our sun-loving plants are native to environments with long, sunny days which are not easily mimicked during darker winter months. One of the most simple ways to combat lower light levels is by moving plants closer to the windows in our home.
If not already, cacti and succulents can be placed directly on windowsills. Other foliage plants can be brought closer to windows but should be kept out of drafty areas. Another way to supplement the lack of sun is through artificial lighting. We have many different grow lights available, some of which can be installed into decorative lamps.

Dry air in our homes is another issue that arises in the winter and can cause various problems for our indoor plants. Many indoor plants (like calatheas and orchids) crave humid environments. Grouping humidity-loving plants together can help increase overall humidity levels. Additionally, misting these plants regularly or setting plants on trays of pebbles that are filled with water will also increase humidity levels.
Dry air provides ample breeding grounds for pests like spider mites; check plants regularly for signs of infestation and treat accordingly. Insecticidal soaps are an easy solution to control pests. To use, spray pests directly and check back often to ensure the infestation has been controlled. Alternatively, plants with smooth leaves (not African violets, begonias, or Cissus) can be wiped down with dish soap and water to keep any pests at bay. Regularly showering plants can also help knock off pests and prevent leaves from drying out (avoid fuzzy leaf varieties and drought-loving plants).

Much like us, our houseplants take a rest during the winter, meaning that they do not need as much to keep healthy. Avoid repotting indoor plants during the winter months to give them a chance to rest.
Issues from overwatering are much more common during the winter months, so be vigilant to not water wet plants and air on the side of keeping things dry. Many cacti and succulents can go months without watering in the winter. From the months of October to March, most houseplants should not be fertilized as they are no longer actively growing.
By following these practical tips, your houseplants will remain happy and health all season long.
