We’ve all been there—buying a gorgeous houseplant full of hope, only to watch it slowly wither away a few weeks later. It’s easy to think you’re just not a “plant person,” but here’s the truth: Most plant deaths come down to a few common mistakes, not some personal curse.
The good news? Once you know what these mistakes are—and how to fix them—keeping plants alive becomes so much easier. Even if you’ve killed every plant in the past, you can turn things around. You just need the right knowledge and a little patience.
So, let’s break it down. Here are nine of the most common indoor plant care mistakes that often trip up beginners, along with simple, practical solutions that’ll help you grow a thriving indoor garden.
9. Inconsistent Care: Plants Love Routine (Just Like Us)
Plants might not have calendars, but they do thrive on consistency. Forgetting to water for weeks, then drowning them in guilt, stresses your plants out. Skipping sunlight or leaving pruning for “someday” can also slow their growth and make them more prone to pests or disease.
The easiest way to avoid this is to build plant care into your weekly routine. Pick a day—like Sunday—and make it your “plant check-in day.” Walk around your home, check the soil, give thirsty plants a drink, and trim any dead leaves. It doesn’t need to take more than 10-15 minutes.
Pro Tip: Download a free plant care tracker or set phone reminders so you won’t forget watering days.
8. Pest Problems: Little Bugs, Big Trouble
If you’ve noticed sticky leaves, weird webs, or tiny moving dots on your plants, pests like spider mites, aphids, or fungus gnats might be the culprits. They can weaken your plants and make them look sickly—fast.
The best defense is a weekly check-up. Look under the leaves and along the stems for any signs of bugs. If you spot pests early, they’re easier to manage. Washing the leaves with mild soapy water often works, but if the infestation is worse, natural sprays like neem oil can save the day.
Pro Tip: Always check new plants for bugs before bringing them home. A quick rinse under lukewarm water can prevent unwanted hitchhikers from spreading.
7. Low Humidity: Dry Air Can Be a Silent Plant Killer
Some plants, especially tropical ones like ferns and calatheas, love humidity. If your home is on the dry side—especially in winter—those brown, crispy leaf tips are their way of crying out for moisture.
If you don’t want to turn your living room into a rainforest, grouping your plants together can help create a more humid environment. Placing a tray of water with pebbles under your plants can also raise humidity slightly. For an extra boost, a humidifier works wonders, especially if you have several humidity-loving plants.
Pro Tip: Bathrooms often have naturally higher humidity, making them a great spot for ferns or peace lilies if they get some natural light.
6. Using the Wrong Soil: Not All Dirt Is Equal
Soil might seem like “just dirt,” but choosing the wrong type can hold your plants back. Regular garden soil is often too dense for indoor plants, holding too much water and suffocating the roots.
For most houseplants, an all-purpose potting mix works well, while succulents and cacti need a fast-draining, sandy blend. If you’re not sure, the bag usually says what it’s good for—look for “indoor plants,” “succulents,” or “tropical plants” on the label.
Pro Tip: When repotting, choose a pot with drainage holes. Without those holes, excess water gets trapped, leading straight to root rot.
5. Picking Fussy Plants: Don’t Start With Divas
It’s tempting to pick that stunning fiddle leaf fig or rare orchid on Instagram, but some plants are like high-maintenance celebrities—they need constant attention. Beginners often have more success with hardy, forgiving plants.
If you’re just starting, look for easy-going options like snake plants, pothos, ZZ plants, or spider plants. These tough houseplants handle neglect well and can survive the occasional mistake.
Pro Tip: Once you get comfortable with the easy plants, you can gradually introduce more delicate ones. Think of it like leveling up in the plant world!
4. Overcrowding: Plants Need Personal Space Too
It’s fun to create a jungle vibe indoors, but cramming plants too close together can block airflow, increasing humidity and inviting pests like mold or gnats. Plus, light can’t reach every leaf when plants are crowded, leading to weak, leggy growth.
Give your plants a little breathing room. Ideally, there should be space between pots so light and air can circulate. If you’re tight on space, vertical plant stands or hanging planters can maximize your greenery without overcrowding your shelves.
Pro Tip: Rotate your plants every few weeks so all sides get light evenly, preventing lopsided growth.
3. Bad Lighting: Not All Plants Love the Sun
One of the biggest plant mistakes beginners make is putting plants in the wrong light. Too much sun can scorch leaves, while too little can cause slow growth and sad, yellowing foliage.
Before buying a plant, check its light preferences. Some plants, like snake plants or ZZ plants, tolerate low light well, while succulents and cacti need bright, indirect sunlight to thrive. If your home is a bit dark, LED grow lights can give your plants a boost.
Pro Tip: Windowsills can be great, but watch for drafts in winter—cold air can shock your plants.
2. Underwatering: Plants Get Thirsty Too
Forgetting to water plants is a classic mistake, especially for busy people. While some plants forgive the occasional dry spell, consistently dry soil can cause leaves to droop, curl, or fall off.
The easiest way to know when to water is the finger test. Stick your finger into the soil up to your knuckle—if it feels dry, it’s time to water. For even less guesswork, self-watering pots can do the job for you.
Pro Tip: If you travel often, group plants together before you leave and give them a deep watering. It helps them stay hydrated a little longer.
1. Overwatering: The Number One Plant Killer
If there’s one mistake nearly every beginner makes, it’s giving plants too much water. It feels like you’re helping, but drenched soil suffocates roots, leading to root rot and mold.
The key is to only water when your plant needs it. Most plants prefer their soil to dry out slightly between waterings. Feeling the soil is better than watering on a fixed schedule because some plants need more water in summer and less in winter.
Pro Tip: If you often overwater, a moisture meter can be a lifesaver. It tells you exactly when the soil is dry so you’re not guessing.
It’s All Part of the Learning Curve
Every plant parent makes mistakes—it’s part of the journey. The important thing is learning from those moments and making small changes. Start by focusing on one or two areas, like watering or lighting, and build your confidence from there.
Before long, you’ll not only keep your plants alive but actually watch them thrive. And trust me—that first new leaf is one of the best feelings ever.
