Why Winter is Tricky for Houseplants

So, why is winter such a challenging season for indoor plants? During the colder months, everything changes – temperatures drop, the air gets drier, and natural light becomes weaker and less frequent.

Most houseplants naturally slow down their growth in winter, but even though growth slows, they’re still alive and need care. The key is to adjust your routine. Treating plants the same way you do in summer can cause damage or even lead to losing them.

Mistake #1: Overwatering

One of the most common winter houseplant care mistakes is overwatering. Signs include yellowing leaves, soggy soil, or a strange smell from the pot.

Since plants grow more slowly in winter, they use less water. If watered on a summer schedule, the soil stays wet too long, leading to root rot – a silent killer that spreads quickly.

✅ Solution: Water less often and only when the soil is dry. Stick your finger an inch or two into the soil: if it’s dry, water; if damp, wait a few more days. Always check below the surface because heating can dry the top layer while the bottom remains wet. Remember, it’s better to underwater than overwater.

Overwatering is one of the most damaging winter houseplant care mistakes because it often leads to root rot.

Mistake #2: Sudden Temperature Changes & Low Humidity

Warm, dry indoor air and cold drafts are stressful for plants. Crispy leaf tips or sudden leaf drop often point to this issue.

• Keep plants away from radiators, heaters, and vents.
• Ensure leaves aren’t touching cold windows, especially at night.
• Use a humidifier, group plants together, or place them on a pebble tray with water.

Stable humidity and temperature are vital for healthy winter houseplants. Sudden drafts and dry air are classic winter houseplant care mistakes that weaken plants silently.

Mistake #3: Fertilizing in Winter

Fertilizing during winter might seem harmless but can do more harm than good. Most plants slow down or stop growing in this season, meaning they don’t need extra nutrients.

If you keep fertilizing, unused nutrients build up in the soil, creating a toxic environment that burns roots and causes brown leaf tips.

✅ Solution: Pause fertilizing until spring when growth resumes. The exception: fast-growing tropicals or herbs that actively grow in winter – use diluted fertilizer sparingly.

Fertilizing when plants aren’t actively growing is among the easiest winter houseplant care mistakes to avoid – simply wait until spring.

Mistake #4: Repotting in Winter

Another common winter houseplant care mistake is repotting during the cold season. Repotting in winter stresses plants because they are in a restful phase, focusing on survival rather than growth. Disturbing roots at this time can shock the plant.

Unless your plant is root-bound or suffering from root rot, wait until spring or summer to repot. That’s when they can recover quickly and adapt to a new pot.

Mistake #5: Not Enough Light

Lack of light is one of the biggest challenges in winter. Symptoms include yellow leaves, stretched growth toward windows, or slowed growth.

• Move plants closer to south-facing windows.
• Clean your windows to maximize light.
• Consider grow lights if natural light isn’t sufficient.

Light is life for plants, and in winter they need all the help they can get. Not providing enough light is perhaps the most overlooked of all winter houseplant care mistakes.

Extra Winter Plant Care Tips

Beyond the five biggest winter houseplant care mistakes, here are two bonus tips for even healthier plants.

1. Clean the Leaves

Dust builds up on leaves in winter, blocking precious light. Wipe them with a damp cloth or give a gentle shower. Clean leaves absorb more light and stay healthier.

2. Play Music for Your Plants

It may sound unusual, but music can support plant growth. I play a daily playlist of frequencies for my plants, and I’ve seen stronger growth and healthier leaves. Try it yourself—it’s a simple way to boost growth and create a calming space at home.
