Do you sometimes feel like you need a green thumb to keep your plants alive? Are you unsure about the best practices for plant care? In this article, we will uncover the truth behind common plant care myths and provide you with the knowledge and tools to care for your plants effectively. Whether you’re a beginner or an experienced plant parent, understanding these myths and the facts behind them will help you provide the best care for your green friends.

Myth: Placing pebbles in the bottom of a pot improves drainage

One common myth is that placing pebbles or rocks at the bottom of a pot improves drainage. The idea is that the pebbles create space for water to flow out of the soil. However, the reality is that water does not easily move from the potting soil to the pebbles. Instead, it tends to stay within the potting mix, potentially leading to waterlogged roots and root rot. To ensure proper drainage, it is best to choose a pot with drainage holes at the bottom. These holes allow excess water to escape, preventing overwatering and promoting healthier root growth.

Myth: Misting your houseplants increases humidity

Another common myth is that misting your houseplants increases humidity. Many people believe that misting the leaves with water can create a humid environment for the plants. However, the truth is that misting only provides temporary humidity in a small area. The moisture quickly evaporates into the surrounding air, having little effect on overall humidity levels. If you want to increase humidity for your houseplants, running a humidifier or grouping plants together can have a more significant impact.

Myth: Wilting always means a plant needs watering

You may have been told that wilting is a sign that your plant needs watering, but this is not always the case. While wilting can be an indication of thirst, it can also be caused by other factors such as inadequate light, pests, or overwatering. Before watering your plant, it’s important to assess its overall condition. Check the soil moisture by using the “finger test.” Stick your finger about an inch deep into the soil, and if it feels dry, it’s time to water. Remember, overwatering is often a more common problem than under-watering, so be cautious and avoid drowning your plants.

Myth: Houseplants significantly improve indoor air quality

You may have heard that houseplants can purify the air and improve indoor air quality. While it is true that plants absorb carbon dioxide and release oxygen, their impact on indoor air quality is minimal. The idea that houseplants can remove chemicals from the air was based on a small study that suggested certain plants could remove specific pollutants. However, for significant pollutant removal, a large number of plants would be required, far more than the average home can accommodate. Instead of relying solely on plants for air purification, it is best to ensure proper ventilation and use other methods such as air purifiers for better indoor air quality.

Myth: Houseplants always require fertilization

Many people believe that all houseplants need frequent fertilization to thrive. While plants do require nutrients for growth, if you are using a good potting mix that already contains nutrients, your houseplants may not need additional fertilization. Most potting mixes on the market are formulated with a slow-release fertilizer that provides nutrients for several months. Additionally, houseplants can make their own food through photosynthesis, using sunlight, water, and carbon dioxide. However, if you notice signs of nutrient deficiencies such as yellowing leaves or stunted growth, it may be time to consider fertilizing your plants.

Myth: Pebble trays effectively increase humidity

You may have heard that placing a tray of water and pebbles under a plant can increase humidity levels. The idea is that the water will evaporate, creating a more humid environment for the plant. However, the truth is that water molecules evaporate in all directions, not just towards the plant. The small amount of humidity created by pebble trays does not significantly increase overall humidity levels. If you want to raise humidity for your plants, a more effective method is to group plants together in a confined space. As they release moisture through transpiration, they create a microclimate with higher humidity.

Myth: Watering plants on a schedule is advisable

Many people follow a watering schedule for their plants, believing that a specific frequency is necessary for plant health. However, watering needs vary among plants. Different factors such as the type of plant, pot size, and environmental conditions affect how often plants need watering. Following a strict schedule without considering these factors can lead to overwatering or underwatering, both of which can be detrimental to plant health. Instead of adhering to a fixed watering schedule, it is important to learn the specific requirements of each plant and water accordingly. The “finger test” can help determine soil moisture levels and guide you in determining when to water.

Myth: Low-light plants thrive in any lighting conditions

Plants marketed as “low-light” plants are often thought to thrive in areas with minimal light. However, the truth is that all plants, including those labeled as low-light plants, require some level of light to survive. While these plants may tolerate lower light conditions better than others, they still need a certain amount of light to carry out photosynthesis, the process by which they make food. If you have low-light conditions in your home, consider using LED grow lights to provide the necessary light for your plants’ growth.

Myth: Leaf shine products are good for plant care

Leaf shine products, often marketed as a way to make your plant’s leaves glossy and attractive, can actually be harmful to plant health. These products typically contain oils or synthetic chemicals that can clog the stomata, the plant’s pores, hindering water evaporation, nutrient absorption, and photosynthesis. Instead of using leaf shine products, it is recommended to dust your plants with a damp cloth or rinse them off with a gentle mist of water. This will help keep leaves clean and free from dust, enabling them to carry out their natural functions effectively.


In this article, we have debunked common plant care myths and provided you with accurate information to ensure the health and thriving of your houseplants. It is essential to understand the specific needs of each plant, such as watering requirements, lighting preferences, and environmental conditions. By avoiding these myths and following proper plant care practices, you can provide the best care for your plants, leading to vibrant and thriving greenery in your home.
