Plants are an essential part of life, providing oxygen, food, and natural beauty to our world. However, over the years, several plant myths have spread, leading to misconceptions about how plants grow, survive, and interact with their environment. Some of these myths have been passed down for generations, while others have gained popularity due to misunderstandings or misinformation.
Have you ever heard that talking to plants makes them grow faster? Or that cactus plants don’t need water at all? What about the idea that cutting a tree’s roots will make it die instantly? Some of these claims sound logical, while others seem too strange to be true. But how much truth is behind them?
In this article, we’ll uncover the most common plant myths and reveal whether they are fact or fiction.
Myth #1: Talking to Plants Helps Them Grow Faster
Reality: Some studies suggest that plants respond to sound, but it’s not as simple as just talking to them.
Many gardeners believe that speaking to their plants can boost growth. This idea comes from the belief that plants can “hear” human voices and thrive when they receive attention.
Scientific studies have shown that plants can respond to sound vibrations, but it doesn’t necessarily have to be human speech. Some experiments suggest that classical music, nature sounds, or even the hum of insects can affect plant growth.

For example, a study conducted by the Royal Horticultural Society found that plants exposed to recorded voices grew slightly more than those in complete silence. However, the effect was minimal. The key takeaway? While talking to plants won’t hurt them, it’s the care you give them—like watering and sunlight—that truly helps them grow.
Myth #2: Cactus Plants Don’t Need Water
Reality: Cacti do need water, but they require less frequent watering compared to other plants.
Many people assume that cactus plants never need water because they grow in deserts. While it’s true that cacti are drought-resistant, they still require moisture to survive.
Cacti store water in their thick, fleshy stems, allowing them to survive in hot, arid environments. However, if left completely dry for too long, they can still shrivel and die.
The correct way to care for a cactus is to water it deeply but infrequently. The soil should dry out completely between waterings. Overwatering, on the other hand, is the biggest threat to cacti, as it can cause root rot.
Myth #3: Plants Need Direct Sunlight to Grow
Reality: While sunlight is essential, not all plants require direct sun—some prefer shade or indirect light.
Many people assume that all plants need bright, direct sunlight to survive. While it’s true that plants require light for photosynthesis, different species have different light requirements.
Some plants, like tomatoes and succulents, thrive in full sunlight. Others, such as ferns and snake plants, grow best in indirect or low light conditions.

Indoor plants like pothos, ZZ plants, and peace lilies are perfect examples of species that flourish in low-light environments. So, if you live in an apartment with limited natural light, don’t worry—there are plenty of plants that can still thrive.
Myth #4: Cutting a Tree’s Roots Will Kill It Instantly
Reality: While cutting roots can damage a tree, most trees can survive if they have enough remaining healthy roots.
Some believe that cutting a tree’s roots will immediately kill it, but this isn’t entirely true. Trees have a vast root system, and they rely on these roots for water, nutrients, and stability.
If only a small portion of the roots is cut, the tree may recover over time. However, if a large number of roots are damaged or removed, the tree can become weak, struggle to absorb nutrients, and eventually die.
When pruning tree roots, it’s important to avoid cutting too many at once and always consult a certified arborist if unsure.
Myth #5: Watering Plants in the Afternoon Burns Their Leaves
Reality: Watering during the hottest part of the day isn’t ideal, but it won’t burn the leaves.
One of the most common gardening myths is that water droplets on leaves act like magnifying glasses, causing the sun to burn the plant. While this theory sounds logical, studies show that water droplets evaporate too quickly to cause significant damage.
That said, watering in the afternoon isn’t recommended—not because of burning, but because water evaporates too fast in the heat. The best times to water plants are early morning or late evening, when temperatures are cooler, allowing the water to soak into the soil effectively.
Myth #6: Adding Sugar to Soil Makes Plants Grow Faster
Reality: Plants don’t absorb sugar from the soil—they make their own through photosynthesis.
Some believe that adding sugar or soda to the soil will make plants grow faster. However, plants create their own energy using sunlight, water, and carbon dioxide.
In fact, adding sugar to the soil can do more harm than good by disrupting microbial balance and attracting pests. Instead of sugar, focus on providing proper nutrients through compost or fertilizer.
Myth #7: Houseplants Improve Oxygen at Night
Reality: Some plants release oxygen at night, but the effect is not significant enough to impact air quality.
Many people believe that keeping houseplants in the bedroom can increase oxygen levels and improve sleep. While plants do produce oxygen, most stop releasing it at night when photosynthesis halts.
However, a few plants—such as snake plants, aloe vera, and orchids—continue to release oxygen even in the dark. While this might slightly improve air quality, the effect is not enough to replace proper ventilation in a closed room.
Myth #8: Orchids Are Impossible to Grow
Reality: Orchids can be easy to grow with the right care, but they require specific conditions.
Many gardeners are intimidated by orchids, thinking they are difficult to grow. While orchids do have specific needs, they are not as high-maintenance as some believe.
The key to growing orchids successfully is to provide the right amount of light, humidity, and airflow. Most orchids thrive in indirect sunlight, well-draining orchid mix, and occasional watering.
With proper care, orchids can rebloom for years, making them a rewarding addition to any home.
Separating Plant Myths from Facts

FAQs About Common Plant Myths
Do plants feel pain?
No, plants lack a nervous system or brain, so they cannot feel pain like humans or animals.
Does misting plants replace watering?
No, misting can increase humidity, but it does not provide enough water for a plant’s roots.
Can coffee grounds help all plants grow?
Not all plants benefit from coffee grounds—some prefer acidic soil, while others may be harmed.
Should you add ice cubes to orchids?
No, ice cubes can shock the roots. Room-temperature water is best for orchids.
Do bigger pots help plants grow faster?
Not always. If a pot is too big, excess soil can retain too much moisture, leading to root rot.
