As the seasons change, so do the needs of your indoor plants. This guide provides a step-by-step checklist for transitioning your houseplants into autumn, covering adjustments in watering, light, and feeding, as well as preparing them for the early heating season.

A Note From Our Plant Expert

Hello plant lovers! It’s Anastasia here. Autumn has a special magic, doesn’t it? The cozy sweaters, the crisp air, the warm drinks. But as we start spending more time indoors, it’s the perfect moment to give a little extra love to our green companions.

The shift from summer to fall is a big transition for our houseplants. The days get shorter, the light changes, and soon the heating will click on, creating a drier environment. Don’t worry, I’m here to guide you through it. I’ve learned from experience that a little prep work now can make all the difference for a happy, healthy indoor jungle through the winter.

Today, I’ll share my essential checklist to help you confidently prepare your houseplants for the changing season. Let’s get them cozy for autumn!

☀️ Adjusting to Light Changes

As the days shorten and the sun’s intensity wanes, your houseplants will receive less light. The bright, sunny spot that was perfect in July might be too dim by October.

To help them make the most of the available light, you can move your plants closer to a window. Don’t worry about leaf scorch at this time of year; the autumn sun is much gentler. You can also give their leaves a gentle wipe with a damp cloth. Clean leaves can absorb sunlight more efficiently. For those in darker homes, a grow light can be a great investment to supplement natural light.

💧 Watering Adjustments

With less light and slower growth, your plants’ water needs will decrease significantly. Overwatering in the fall and winter is one of the most common houseplant problems, and it can lead to root rot.

The “finger dip test” is your best friend. Before watering, stick your finger about two inches into the soil. If it feels dry, it’s time to water. If it’s still damp, wait a few more days. You’ll likely find that your watering schedule shifts from weekly to once every two weeks or even less. When you do water, do it thoroughly, allowing the excess to drain away completely.

🔥 Early Heating Season Prep

The day we turn on the heating is a big change for our plants. Central heating creates a dry environment, which is the opposite of the humid, tropical conditions most houseplants love.

Boost Humidity

You’ll want to increase the humidity around your plants. Grouping them can create a more humid microclimate. You can also place them on pebble trays filled with water or, for your most sensitive plants, run a cool-mist humidifier nearby. You might also find our article on plants that love humidity helpful.

Watch for Drafts and Vents

Keep your plants away from cold drafts from windows and doors, as well as direct blasts of hot air from heating vents or radiators. Consistent temperatures are key to a happy plant.

Stop Fertilizing

Most houseplants go into a dormant period in the fall and winter, so they don’t need to be fed. Stop fertilizing around the end of September. Feeding them when they’re not actively growing can do more harm than good.

Hold Off on Repotting

Autumn is not the time for repotting. Since the plant isn’t in a growth phase, it will have a harder time establishing its roots in a new pot. Wait until spring unless it’s an emergency. For more on this, see our guide to repotting.

Tidy Up

It’s normal for some leaves to yellow and drop as your plant prepares for winter. Prune away any dead or dying leaves to keep your plant looking its best and to prevent any potential pest or disease issues.

📝 Autumn Care Checklist

Here’s a quick rundown of your autumn houseplant care tasks.

Bring Outdoor Plants Inside

If you moved any houseplants outside for the summer, bring them in before the first frost. Inspect them thoroughly for any pests that might have hitched a ride. It’s a good idea to quarantine them for a week or two to be safe.

Adjust Lighting

Move your plants closer to a light source as the days get shorter. Use our Houseplant Light Guide to find the perfect spot this season.

Adjust Watering

Reduce watering frequency as the plant’s growth slows. Use our Ultimate Watering Guide to adjust your watering schedule.

Frequently Asked Questions

How often should I water my houseplants in the autumn?

Watering frequency should be reduced in the autumn. Allow the top two inches of soil to dry out before watering again. For many plants, this could mean watering every two weeks or so.

Should I fertilize my houseplants in the fall?

It’s best to stop fertilizing most houseplants by the end of September. As their growth slows for the dormant season, they no longer need the extra nutrients.

My plant's leaves are turning brown, what should I do?

Brown leaf tips can be a sign of dry air, especially once the heating is on. Increasing humidity with a humidifier or a pebble tray can help. It’s also normal for some older leaves to die back as the plant conserves energy for winter.

Do I need to move my plants in the autumn?

Yes, it’s a good idea to move them closer to a light source as the days get shorter. Also, be mindful of drafts from windows and doors, and keep them away from direct heat sources.

When should I bring my outdoor plants inside for the winter?

Bring any houseplants that have been summering outdoors inside before the first frost. Most houseplants can’t tolerate temperatures below 55°F (13°C).
