Most people either water too much or too little. Overwatering is the most common way people kill their plants. It’s not about how often you water—it’s about how wet the soil is.
Basic Rule:
Don’t water until the top inch of soil is dry.
Stick your finger into the soil. If it feels moist, don’t water. If it’s dry, go ahead. That’s it.
Why Overwatering Kills:
Roots need air. If the soil is always soaked, the roots rot. Once that happens, it’s usually game over.
Signs You’re Overwatering:
- Leaves turn yellow and drop
- The soil smells bad
- The plant feels limp even though the soil is wet
Underwatering Isn’t Great Either:
Letting the soil go completely bone dry for long stretches will stress most plants. Some tolerate it better (snake plants, succulents), but most don’t.
Use the Right Pot:
Plants need pots with drainage holes. No drainage = trapped water = rot. Always.
Light: More Important Than You Think
Plants need light to make energy. No light, no growth. It’s that simple.
Different Plants, Different Needs:
- Low light plants: pothos, snake plant, ZZ plant
→ These can survive in dim corners. - Medium light plants: peace lily, dracaena, philodendron
→ Need filtered light near a window. - Bright light plants: fiddle leaf fig, succulents, cacti
→ Want direct sun for several hours.
If your plant isn’t getting the light it needs, it won’t die right away—but it’ll stop growing, get leggy, or drop leaves.
Test Your Light:
- Stand where the plant is and look around during the day.
- If you can read a book easily without turning on a light, that’s medium light.
- If there’s direct sunlight on the spot for hours, that’s bright light.
- If you can’t see well, that’s low light.
Moving Your Plant:
If your plant isn’t doing well, try moving it closer to a window. It can make a big difference.
Humidity and Air
Most tropical houseplants like humidity. If you live in a dry area or use a lot of indoor heat in winter, your air might be too dry.
Signs It’s Too Dry:
- Brown leaf tips
- Crispy edges
- Leaves curl up
What Helps:
- Grouping plants together
- Using a humidifier
- Placing the pot on a tray with water and pebbles (don’t let the pot sit in the water)
- Moving plants into the bathroom if it gets good light
You don’t need to mist your plants every day. It’s fine if you do, but it doesn’t change humidity much unless you do it constantly.
Temperature
Most houseplants like the same temperatures people do—65 to 75°F (18 to 24°C). Don’t put them right next to a heater, air vent, or a freezing window.
Sudden cold drafts can damage them. So can hot, dry air.
Soil and Repotting
Don’t Use Garden Soil:
Use potting mix. It’s lighter and drains better.
When to Repot:
- If roots are coming out of the bottom
- If water runs straight through without soaking in
- If the plant looks stunted and hasn’t grown in months
Repot in spring if you can. Go one pot size up. Loosen the roots a bit before placing it in fresh soil.
Fertilizer
Plants in pots use up the nutrients in soil over time. You need to feed them sometimes—but not too much.
Basic Rule:
Feed once a month during spring and summer. Don’t fertilize in fall or winter when most plants slow down.
Use a basic houseplant fertilizer and follow the directions. Liquid fertilizer is easy to control.
Too much fertilizer can burn roots and damage your plant. More isn’t better.
Common Mistakes
Here’s what trips most people up:
- Ignoring light.
People buy plants for how they look, not where they’ll live. But light matters more than you think. - Overwatering.
Just because the top of the soil looks dry doesn’t mean the bottom is. - Using the wrong pot.
Those pretty pots without holes? Great for looks, bad for plants. If you use them, keep the plant in a plastic nursery pot and slip it inside. - Not checking for pests.
Look under the leaves. Check for webbing, sticky spots, or little bugs. Wipe leaves with a damp cloth if you see anything. - Forgetting to clean the leaves.
Dust blocks sunlight. Wipe leaves once in a while with a damp cloth. - Moving plants too much.
Most plants like consistency. Don’t drag them around every week.
Pet Safety
Some houseplants are toxic to pets. If your cat or dog likes chewing on leaves, stick to safe options like:
- Spider plant
- Areca palm
- Peperomia
- Calathea
Avoid lilies, pothos, philodendron, dieffenbachia, and ZZ plant if pets are a problem.
Where to Put Them
Think about light and traffic.
- Bright windows: great for succulents, cacti, figs
- North-facing rooms: good for low-light plants like pothos or snake plant
- Kitchens and bathrooms: usually humid, good for tropicals
- Away from high-traffic spots if you have kids or pets
If a plant keeps getting knocked over, either move it or get a sturdier one.
Getting Help
Don’t guess. If you’re not sure what’s wrong, take a picture and ask someone at a local plant shop or online forum. You’ll learn faster that way.
Final Advice
Start small. Pick one or two easy plants. Don’t try to create a jungle overnight. Once you’ve kept a few alive for six months, then try more.
And don’t feel bad if one dies. Everyone kills a plant at some point. Just learn from it.

Nutritional Info (for the curious)
No, you’re not eating your houseplants—but some people like to know the air-quality or psychological benefits. While that’s hard to measure precisely, a few facts:
- Plants can slightly improve indoor air quality by removing small amounts of toxins
- They can increase humidity through transpiration
- Some studies show indoor plants may reduce stress and improve concentration
But don’t expect miracles. They’re not air purifiers. They’re just plants.
