Autumn Care Tips for Your Philodendron Plant

Understanding the Seasonal Needs of Your Philodendron

As autumn rolls in, the care requirements for your Philodendron plant may change. The drop in temperature, less daylight, and indoor heating can affect the plant’s health. Philodendrons, which are tropical by nature, often need special attention during this time to thrive. By adjusting your care routine, you can help your Philodendron stay vibrant throughout the fall season.

Regulate Temperature and Humidity

Philodendrons prefer warm and humid conditions similar to those in their native tropical environments. With the onset of cooler weather, it is crucial to protect your plant from drafts and sudden temperature changes. Ideally, maintain indoor temperatures between 65°F and 78°F. If you use heaters in your home, ensure that your plant is not exposed to direct hot air, which could cause it to dry out more quickly. To maintain adequate humidity, consider using a room humidifier or placing the plant’s pot on a tray of water with pebbles, ensuring the pot does not sit directly in the water to prevent root rot.

Adjust Watering Habits

In autumn, your Philodendron will require less water than in the spring and summer months due to cooler temperatures and reduced growth rates. Overwatering can lead to root rot and other issues. Check the top inch of the soil for dryness before watering. If it’s dry to the touch, it’s time to water. If it’s still moist, wait a few more days and check again. Ensure that your Philodendron’s pot has excellent drainage to avoid water accumulation at the bottom.

Optimize Light Exposure

With shorter days, your Philodendron will receive less natural sunlight. Position the plant in a spot where it can get bright, indirect light to compensate for the reduced intensity and duration of daylight. However, be careful to avoid direct sun exposure, which can scorch its leaves. If natural light is insufficient, consider using grow lights to provide the necessary spectrum of light to support its health and growth.

Fertilize Sparingly

As growth slows in the fall, your Philodendron will not need as much fertilizer. Over-fertilizing can harm the plant when it is not actively growing. It is generally recommended to stop fertilizing altogether during the autumn and winter months. If you do choose to fertilize, use a balanced, water-soluble fertilizer at half of the recommended strength, once every 6 to 8 weeks.

Prune and Clean as Needed

Pruning is less frequently required during autumn since growth slows, but keep an eye out for any yellowing or dead leaves. Gently prune these away to redirect energy to healthier parts of the plant. Also, ensure to dust the leaves regularly, as dusty leaves can hinder photosynthesis. Use a damp cloth to gently wipe them down, which will also help in pest prevention.

Be Vigilant about Pests

Indoor heating systems can lead to dry indoor air, which can attract spider mites and other pests. Regularly check your Philodendron for signs of infestations, such as mottled leaves or webbing. If pests are spotted, treat your plant immediately with neem oil or insecticidal soap, being careful to follow the product instructions.


Autumn can be a challenging time for indoor plants like Philodendrons, but with the right care, they can continue to flourish. By managing environmental factors such as temperature, humidity, and light, adjusting your watering and fertilization routine, and keeping up with maintenance like pruning and pest control, you can ensure your Philodendron remains a healthy and beautiful part of your home as the seasons change.
