Preparing Houseplants for Winter

Preparing Houseplants for Winter

During the spring and summer months, it is not uncommon to bring your houseplants outside to give them a little extra sunlight and warmth. It generates new growth and root development and spruces up your patio or screened-in porch. But, with the colder months approaching, it is wise to plan to bring your houseplants inside. Most houseplants are considered tropicals and cannot withstand temperatures below 50 degrees Fahrenheit. There are many tasks to complete when preparing houseplants for winter!

Clean Leaves

After spending the spring and summer outside, your plants’ leaves may have accumulated a lot of dirt and dust. You can wet a paper towel or cotton cloth and wipe down the leaves. For the small crevices, use a small paintbrush to brush out any dirt.

Inspect and Treat Plants

It is always good practice to thoroughly inspect your plants. This is especially important if you still have plants inside that were never brought out! The chances of infestation when bringing plants back inside is very high, and disease and insects can spread rapidly! Be sure to inspect under leaves, along the stocks and stems, and around the soil line. If you discover insects, be sure to treat them with an organic insecticide. Once all plants are inspected and treated, apply a systemic granule insecticide to all plants. This will prevent any insects that you may have missed from growing.

Prune Off Dead

Upon inspecting your houseplants for disease and insects, you may notice some dead or yellowing leaves. Now is an excellent time to prune off any dead or struggling leaves. This will also help in preventing disease while wintering over indoors. Remember to clean the soil line, removing any debris that may have collected while outdoors.


Depending on where you live, you may have another 2-4 weeks of warm weather. Here in North Carolina, we are still experiencing summer-like temperatures! If this is the case, you have a couple more weeks to feed your plants. If you want to get one last feeding in, use a water-soluble fertilizer and dilute it by half.
