Have you struggled to keep houseplants in good condition over the winter? Or maybe winter is coming and you are nervous that you are going to kill your houseplants?

Keep reading because I will go over 7 things that you can do (or NOT do) to keep your houseplants alive this winter! Follow these steps, and you will be golden!

1. Ditch the Watering Schedule

For those of you that follow me closely either on Instagram (@ohiotropics) or on this blog, you know that I’m not a fan of watering schedules, and I will tell you exactly why. It becomes even more important in the winter.

There are so many watering myths that have run rampant!

We’ve all heard the “water once a week” or “water every other week” type of watering schedule. That fact is, your plants may not need water once a week. So how can you tell?

Because of different conditions (pot size, pot type, temperature, size of root system, amount of light, etc.), your plants vary in their needs in terms of how often to water.

In some cases, the timing in which you water your plants might very well be about once a week, given a certain combinations of conditions. But this is not how you should think about watering.

I’ll give you an example and why it is so important. I have a string of bananas plant that during the growing season, I would water about once a week. But I didn’t let the calendar dictate when I watered.

I would check the plant’s soil every week, and it turned out that it fully dried out after about a week, so I would water about weekly.

Fast forward to Fall and Winter time. Darker, shorter days reduce the rate at which plants use water, so it will take longer to dry out.

During the Fall and Winter, after a week of watering, the surface is usually still be damp, so I don’t water. I’ll wait another few days or maybe even another week.

Moral of the story, use your finger to feel the soil. This will tell you when to water your plants. Don’t blindly water just because your calendar tells you so!

However, it IS a beneficial idea to have those regular check points with your plants. So by all means, check your plants at least every week (or even more frequently!) in order to determine if they have any needs.

Sometimes you may need to water at those regular check points, and other times you may need to wait longer.

For example, for succulents, I wait until my soil is fully dried out before watering again. For other plants, I may just let the top inch or so of the soil dry out.

Different plants have different soil moisture needs. Get to know, from a trusted source, what each type of plant likes.

Ditching the watering schedule is always important, but especially in the winter when your plants are less robust and more vulnerable to improper culture.

Succulents can often go quite a long time in the winter without water, especially if temperatures are cooler indoors. Just keep an eye on your plants and watch for signs of stress.

For tropical foliage plants, you may only want the top inch or two of the soil to dry out before you water. Use your finger to determine when to water, not your calendar.

I like to err on the dry side of soil moisture. But don’t wait too long until your plant is showing signs of stress from “underwatering” or “overwatering.”

Overwatering is such an overused, misunderstood and confusing term. It doesn’t mean what most people think it means!

2. Increase Light!

Unless you live near the equator, where light is pretty constant throughout the year, you’ll want to read this!

My dream is to live in a subtropical or tropical region where it is sunny and warm year-round, but since I live in the Northern United States with pretty ugly winters, I have to make some adjustments!

I always, always recommend keeping your houseplants directly in front of a window. In the brighter seasons of the year, you may be able to get away with keeping them further away, but not so much in Winter.

Do your plants a favor and move them to a window if you currently have them far away. Generally speaking, I honestly would consider anything more than 1-2 feet away from a window to be far.

I’ve received pictures from my clients that have plants several feet away from windows. Even up on top of cabinets, several feet away from windows. Your eyes might think it’s bright, but it really isn’t.

No wonder these plants are not doing well! Plants need light to photosynthesize. Period. This is how they make food. Depriving them of light is like not feeding your own children. So give your plants light!

Warning…I’m about to start a little rant. There is a rampant trend out there of “plant styling” going on. That’s perfectly fine to decorate with plants, and plants make any decor very interesting and beautiful.

But before you use plants for interior decoration, please make sure that your plants have their basic cultural needs met first before placing them somewhere!

Pick an appropriate plant for the location, and not the other way around! If you can achieve good light conditions for your plants AND a beautifully styled area, then you are winning!

One other point about light. In the winter, especially if you live in darker, colder areas like I do, you can pretty much place any houseplant in the sun. Or at least areas that get morning sun.

It will benefit them greatly in the winter! Even the “low light” houseplants will benefit from this treatment. Don’t make any broad assumptions from plant labels that label plants as “low light.”

Often times, it just means that they will tolerate low light. They will eventually decline over time. So move those plants right in front, 1-2 feet, of a window. Winter sunshine is a blessing for virtually any houseplant.

If you don’t have any bright windows, you can definitely supplement with artificial lights. Use a grow light to at least supplement your plants’ light needs during the winter if you lack good window space.

3. Keep Your Plants Clean

Be sure to regularly monitor your plants to make sure that their leaves are dust free, especially during the winter.

The interior of your home can get incredibly dusty, especially during the winter time. This will interfere with your houseplants’ ability to breathe through their leaves, and also decrease the amount of light for them.

Cleaning your dusty houseplant leaves will allow your plants to carry out their biological processes, including photosynthesis, more efficiently and therefore be healthier!

The other benefit of keeping your houseplant leaves clean and free of dust, is that it will help to deter any pests. Especially spider mites!

Spider mites will thrive in very dry, warm areas and can be an issue during the winter time when some of our homes have bone dry air.

Do you have a problem with spider mites? Check out my blog post on 3 ways to deal with spider mites with natural products.

So how do I keep my plant leaves clean? Sometimes if I have a larger plant with broad leaves, or a plant that I don’t want to move, I will simply use a mister to spray the leaves down, and then wipe each leaf with a paper towel, rag or sponge.

Other times, if it’s a smaller plant, or a plant that has smaller leaves where it would be difficult to wipe each leaf, I will take it to the sink or the shower. I’ll simply gently spray warm water to wash the leaves off.

Be careful though of certain plants that can potentially rot if water gets stuck in between their leaves or in the crown of the plant.

If you are washing any succulents off, or even Phalaenopsis orchids, be sure to dislodge any water that gets stuck in the leaves or in the crown of the plant.

I have never had any plants rot from this personally, but under the right conditions, you can have certain plants rot if you have water stuck in the crown of the plant, especially if your air circulation is poor.

One of my clients had her moth orchids rot because she would shower them and then placed them in a room and had the door closed all the time. Every single orchid she had suffered from crown rot because of hangin very poor air circulation and standing water in the crown of the plant.

I don’t mean to scare you, but just be aware! Dislodge any water after bathing your plants, especially for succulents and orchids. Gently turn them upside down if you can, or use a sponge or paper towel to dry any water that is stuck in between leaves.

4. Increase Humidity

Winter can bring very dry indoor air, much to the dismay of our plants and our skin! Often indoor humidity can plummet to 30% or even lower in the winter.

There are effective ways to increase humidity, and there are some ineffective ways to increase humidity.

Let me start with the ineffective way. Misting! Sorry, I know there are a lot of misters out there. I used to be one myself.

Misting will not increase the humidity of your air. You’re simply wetting the plant’s leaves and doing very little, if any, to increase the amount of moisture in the air.

Spare your arm muscles, and don’t mist if your only intent is to increase humidity.

So, what are some good ways to increase humidity?

  • Place your plants on top of a tray of pebbles. Add enough water so that the level is right below the pebbles. Then place your plants on top. The evaporating air will increase the humidity around your plant.
  • Group your plants together. Plants naturally release moisture in the air through a process called transpiration. The more plants you group together, the more effective this method is.
  • And finally, get a good humidifier! This is my preferred method since it is easiest (and it’s also good for my skin).

For more information on increasing humidity for your houseplants, be sure not to miss my humidity blog post. In the post, I also talk about the ONLY humidifier that I will ever use. I’ve tested a lot, and it is the best one by far! You will love it!

5. Don’t Fertilize

Quite simply, you don’t want to fertilize when your plant is not growing. With reduced light in the winter, many houseplants will cease growing.

So let your plants rest when they slow down or stop growing. For me, I usually stop fertilizing around October. They will tell you when it is time to grow again. For me, this normally happens around February or March.

In late winter or early spring, when I see signs of growth, I will start fertilizing again. The longer, brighter days will trigger growth and a fresh start!

Not sure how to fertilize, or what kind of fertilizer to your on your houseplants? Check out my How to Fertilize blog post. In the post, I detail how I prefer to fertilize, and which ones I like to use!

6. Be Careful of Temperature Extremes

I almost titled this section “avoid cold drafts” but it is really more than that!

Let’s talk about cold drafts first through. Do you have any plants around doors that you open constantly throughout the winter? This may be detrimental to your plants.

Some houseplants are very sensitive to cold drafts. They may protest and respond by dropping leaves, aborting flower buds, or worse.

So place your houseplants away from any area where they might receive any really cold drafts from opening and closing windows or doors.

Do you have any old, or really drafty windows? You may want to seal your windows with inexpensive kits that you can purchase. This will reduce or eliminate any cold draft that your tender tropical plants hate.

On the other hand, you’ll also need to watch those heating vents! Try and keep your plants away from heating vents. I once had a pothos that crept over right above a heating vent and the leaves literally cooked and burned.

7. Wait on Repotting

Sometimes it is best to wait for certain things and just let things be. Not repotting your houseplants in the winter is one of those things.

In general, the best time to repot is right when your plant is starting its active growing season, or anytime while it is growing.

If you repot a plant while it is resting and not doing much over the winter, you may be inviting problems. Since the plant is not actively growing, the soil will take longer to dry out and potentially cause issues like root rot.

So give it a rest. Both for your sake and your plant’s sake!

Thanks for the great post!!!! I have a monstera that has been doing great but recently it has developed brown crispy edges on leaves....all summer it was doing well and had lots of new growth. Now it has brown, crispy edges and spots in multiple leaves and some different texture on some leaves. I haven't changed anything but I do live in the northern hemisphere (Victoria, Canada). Should I move it closer to a window? It's been I. The same location for a couple of years doing well. I am in a townhouse with o ly East and west faci g windows. It is about 3 feet from my Western window. I am also wondering if it needs repotted. Any suggestions would be great.. I'm so sad it is sick!!!!!! Cheers.

Hello there Amy! Can you send me a photo of your plant in its growing location and also of the crispy edges? What size pot is it in? It may very well need repotting if it has grown well for a couple years. Let me refer you to another post that I wrote on the topic of brown, crispy leaves. It should help!

Hello Raffaele - I look forward to your newsletter every week - thank you. I don't have that many plants but for the ones that i do have - believe me - they are so thankful! You know me and you might already know that i am a bit eccentric - and in that regard - i DO talk to my plants. I think that they like that. After all, they ARE living beings. Funny thing - the ones that i haven't talked to aren't doing that well. The ones that i talk to - like when i water or dust off, they're the ones that seem to grow more. Am i imagining this or is this really possible? Thoughts? Take care, Lucy

Hi Lucy, so nice to hear from you! I'm glad you enjoy my blog! There have been numerous studies and also books that mention the power of intention helping plants to grow. I was reading a book that I can't remember the title of now, but I will let you know once I find it at home! It's pretty fascinating!

Hi, thanks for so of these great tips! This winter is my first time to try grow lights and I'm noticing my plants are putting out new leaves. You mentioned not to fertilize in winter because plants aren't growing, but mine are, so should I continue with a light fertilizer routine? And of course, I'm struggling with fungus gnats and neem oil doesn't seem to be doing the trick. Do you have any ideas on what else I can try? Thanks so much! -Wendy

Hi Wendy! They may slow down soon, but if you are going to use grow lights, they may continue to grow. In which case, you would be OK to fertilize lightly. Especially if you plan to have the lights on for the next few months. The plants won't "know" it is winter if you do so :-) Regardless, if they do slow down, hold back on the fertilizer. As far as fungus gnats go, they proliferate when you keep the soil too moist. It's always a good idea to let the top inch or two dry out before watering again. I have a blog post on fungus gnats where I interviewed someone that had a problem. Check out that post. There is a product called Gnatrol and it's a natural product that works. But if you can prevent them, it is the best thing.
