8 Plant Care Myths You Should Stop Believing

Plant care advice is everywhere, but not all of it is helpful. Some tips that sound smart or go viral on social media can actually do more harm than good. Whether you’re a newbie plant parent or have a full-blown indoor jungle, it’s worth double-checking the “rules” you’ve heard. Below, we’re busting some of the most common myths that could be holding your plants back.

Ice Cubes Are a Cool Way to Water Plants

Using ice cubes for controlled watering might seem clever, but it’s not ideal for most plants. Sudden cold can shock the roots, especially for tropical species that prefer room-temperature water. While it may work for a few types like orchids in moderation, it’s not a one-size-fits-all method. Stick to watering with lukewarm water and adjust the amount based on the plant’s specific needs.

Rocks at the Bottom Improve Drainage

Placing rocks or broken pots at the bottom of your planter doesn’t actually help drainage—it can do the opposite. It creates a water saturation zone above the rocks, which can lead to root rot. Proper drainage comes from using the right soil mix and a pot with a drainage hole. Skip the rocks and let the water flow freely.

Plants Need Constant Watering

Giving your plants a sip daily might feel like love, but it could be overkill. Most plants don’t like sitting in wet soil all the time and need a chance to dry out between waterings. Overwatering is one of the top killers of houseplants. A better approach? Check the soil before watering—if it’s dry a couple of inches down, it’s time to water.

Indoor Light is Always Enough

Not all indoor light is created equal. While some plants tolerate low light, many still need bright, indirect sun to thrive. A dark corner in your living room might not cut it for sun-loving plants like fiddle leaf figs or succulents. Consider placing plants near east- or south-facing windows, or use grow lights if natural light is limited.

Plants Are Just Decor

Sure, plants look great, but they’re living things, not just home accessories. Treating them like static objects can lead to neglect. They need attention, regular care, and sometimes even a change in environment to stay healthy. If you’re bringing a plant home, treat it like a pet with green leaves.

DIY Fertilizers Are Better

Homemade plant food might sound natural and budget-friendly, but it’s not always practical—or safe. Some DIY mixes can throw off soil pH, introduce mold, or attract pests. It’s best to use a balanced, store-bought fertilizer made specifically for your plant type. If you do go the DIY route, do some research first and use it sparingly.

Yellow Leaves Mean Your Plant Needs More Water

Yellowing leaves indicate something’s off, but more water isn’t always the answer. It could also be caused by overwatering, poor drainage, nutrient deficiency, or pests. Instead of grabbing the watering can right away, check the soil, light, and root health first. A little detective work goes a long way in saving your plant.

Egg Whites and Mayo Make Leaves Shine

This old-school hack might temporarily make leaves look shiny, but it can clog the pores your plant uses to “breathe.” That buildup can lead to unhealthy leaves over time. Instead, wipe your leaves with a damp cloth or use a diluted neem oil spray. Your plants will thank you with a healthy, natural glow.

Give Your Plants the Care They Actually Need

It’s easy to fall for plant care myths, especially when they sound convenient or come from a well-meaning friend. But the best thing you can do for your leafy pals is learn what they truly need—and skip the shortcuts. A little knowledge goes a long way in keeping your plants happy and healthy. After all, thriving plants are more than just pretty—they’re a sign you’re doing things right.
