Indoor plants add vibrancy and beauty to any space. However, it’s important to understand that indoor plants are not immune to the effects of seasonal changes. Just like outdoor plants, indoor plants also go through physiological changes as the seasons shift. It is crucial for plant owners to be aware of these changes and provide the necessary care to help their indoor plants thrive throughout the year.

In this article, we will explore the effect of seasonal changes on indoor plants and provide practical tips for seasonal care. We will discuss how seasonal changes affect indoor plants, the adjustments needed in their care routine, and common mistakes to avoid. By the end of this article, you will have a thorough understanding of how to care for your indoor plants as the seasons change.

How Do Seasonal Changes Affect Indoor Plants?

Light Availability

One of the most significant factors affecting indoor plants during seasonal changes is light availability. Just like outdoor plants, indoor plants rely on sunlight for photosynthesis and growth. During the spring and summer months, the days get longer, and the sun is higher in the sky, allowing indoor plants to produce more energy through photosynthesis and enter their growth cycle.

However, as the days become shorter in fall and winter, the quality and quantity of light decrease. This change can have a direct impact on the growth and overall health of indoor plants. Insufficient light can lead to pale or elongated growth, reduced flowering or fruiting, and overall weakened plants.

Temperature Fluctuations

Indoor plants are also affected by temperature fluctuations that occur during seasonal changes. Although indoor temperature changes are generally less extreme compared to outdoor conditions, there is still a noticeable temperature variation between warmer and cooler months.

Most indoor plants originate from tropical regions where the change in temperature between seasons is limited. Nonetheless, these plants may still exhibit responses to seasonal changes, even if they are sheltered from direct outdoor signals.

Plants that typically go dormant during a particular season may still enter their dormancy period triggered by dropping temperatures, even in controlled environments. Other plants that originate from colder regions may exhibit changes in growth patterns or slower growth during the warmer months.

Humidity Levels

Seasonal changes also impact humidity levels in indoor environments, which can affect the health of indoor plants. During the fall and winter seasons, when indoor heating systems are commonly used, the air tends to become drier. This decrease in humidity can result in dry air and decreased moisture levels around plants.

Indoor plants, especially those originating from tropical or humid regions, often require higher humidity levels to thrive. Low humidity levels can lead to dry leaf edges, browning of leaf tips, and increased susceptibility to pests.

Adjustments for Seasonal Care

To help indoor plants adapt to seasonal changes, it is crucial to make certain adjustments in their care routine. Here are some practical tips for seasonal care:

Light Requirements

As the days become shorter during the fall and winter seasons, it is crucial to ensure that indoor plants receive adequate light. Plants should be moved closer to windows to maximize their exposure to natural sunlight. If natural light sources are insufficient, artificial light sources such as grow lights can be used to supplement the lighting needs of indoor plants.

It is important to avoid placing plants directly against windows to prevent extreme temperature changes. Rotating the plants regularly will ensure that all sides of the plant receive equal amounts of light.


Seasonal changes also affect the watering requirements of indoor plants. During the cooler months, most houseplants enter a state of dormancy, resulting in decreased water needs. The soil retains moisture for longer periods, and plant growth slows down.

To prevent overwatering, it is crucial to adjust the watering schedule according to the specific needs of each plant. Before watering, it is important to check the top inch of the soil with your finger. Water the plant only when the soil feels dry to the touch.

It is crucial not to let the plants dry out completely, as this can result in stress and damage to the plant. Finding the right balance and providing adequate moisture without waterlogging the soil is key to ensuring the health of indoor plants.

Indoor Temperature

Maintaining a suitable indoor temperature is vital for the overall health and well-being of indoor plants. Most houseplants prefer temperatures between 18-24 degrees Celsius (65-75 degrees Fahrenheit) during the day, with slightly cooler temperatures at night.

During the fall and winter months, it is important to keep indoor plants away from cold drafts, radiators, or hot air vents. Extreme temperature changes can stress plants and even cause damage. Proper temperature control to mimic the natural habitat of plants will help them thrive throughout the seasons.

Humidity Maintenance

To counteract the dry air commonly experienced during the fall and winter seasons, it is important to maintain adequate humidity levels for indoor plants. This is especially crucial for plants that originate from tropical or humid regions.

Placing indoor plants on water-filled trays with pebbles can help increase humidity levels by providing a localized source of moisture. The evaporating water will naturally increase humidity around the plants. Another option is to use a humidifier to maintain appropriate moisture levels in the air.

Regular misting can also benefit humidity-loving plants like ferns and orchids. However, it is important to avoid misting plants with hairy leaves, as this can promote fungal diseases. Instead, consider placing a humidity tray nearby or using a humidifier.

Common Mistakes to Avoid

To ensure the health and well-being of indoor plants during seasonal changes, it is important to avoid common mistakes that can have adverse effects. Here are some mistakes to avoid:


Overwatering is a common mistake that can lead to root rot and other plant health issues. It is essential to adjust watering schedules according to seasonal changes and the specific needs of each plant. Only water the plant when the top inch of the soil feels dry to the touch.

Neglecting Pest Inspections

Insects and pests can be more active during seasonal changes and can quickly infest indoor plants. Regularly inspecting plants for signs of pest infestation, such as webs, spots, or distorted growth, is crucial. Early detection and prompt treatment can prevent pests from causing significant damage to indoor plants.

Failing to Provide Sufficient Light

Insufficient light can lead to leggy growth, weak plants, and limited flowering or fruiting. It is essential to provide adequate light to indoor plants by adjusting their positioning near windows or using artificial light sources. Regularly rotate the plants to ensure all sides receive equal sunlight.


Indoor plants, although sheltered from the direct impact of outdoor environmental changes, still experience physiological responses to seasonal shifts. Understanding the effect of seasonal changes on indoor plants is essential for providing proper care and ensuring their health and well-being.

Adjustments in light exposure, watering schedules, indoor temperature, and humidity maintenance are crucial for helping indoor plants adapt to seasonal changes. Avoiding common mistakes such as overwatering, neglecting pest inspections, and failing to provide sufficient light will further support the overall health of indoor plants.

By implementing these tips for seasonal care and staying attuned to the specific needs of each individual plant, you can ensure that your indoor plants thrive year-round and continue to bring beauty and joy to your space.
