The Ultimate Guide to Indoor Plant Care
Indoor plants bring life, balance, and beauty into a space, but thriving greenery doesn’t happen by chance. Successful indoor plant care is about understanding how plants live in their natural habitats, then recreating those conditions thoughtfully inside your home.
This guide covers everything you need to know to care for indoor plants with confidence, from light and watering to soil, maintenance, and long-term health.
COVER YOUR PLANT'S BASIC NEEDS
All indoor potted plants rely on the same core essentials: light, water and nutrients. When one of these elements is out of balance, plants show signs of stress. It really is that simple! As we say at Léon & George, a light touch is usually all it takes to ensure your plant thrives.
Light: The Foundation of Indoor Plant Care
Light is the single most important factor in plant health. Most indoor plants prefer and will thrive with bright, indirect light, meaning:
- Near a window
- Protected from harsh, direct sun
Low light does not mean no light, and more sun is not always better. Too little light leads to slow growth and leaf drop, while too much direct sun can scorch foliage. While there are many plants that are considered suitable for low light, most will grow more slowly when placed in dimly light areas.
If a plant isn’t growing or is stretching its stems and/or leaves toward the light, it may be that it needs more light. Check out our full indoor plant light guide for a deeper dive in understanding natural light.

Watering Indoor Plants the Right Way
Overwatering is the most common indoor plant care mistake. Rather than watering on a schedule:
- Check the soil before watering
- Let the top layer dry out between waterings
- Water thoroughly, then allow excess moisture to drain away
Roots need oxygen as much as they need water, which is why it is important to provide drainage for your plant. Constantly wet soil suffocates roots and leads to rot, a common cause of indoor plant decline. Avoid self-watering planters if possible as they can sometimes lead to more harm than good.
Seasonality matters too. Most plants need more water in spring and summer, and significantly less in fall and winter.
Soil & Drainage: The Hidden Essentials
The Best Soil for Indoor Plants
Indoor plants require a well-draining potting mix that holds moisture without becoming compacted. Quality potting soil supports:
- Root health
- Proper airflow
- Efficient nutrient absorption
Avoid using outdoor garden soil indoors as it can be too dense and retains excess water.
Drainage Matters
Whether your planter has a drainage hole or uses a staged setup, water must be able to escape. Standing water leads to stress, disease, and root damage.
Healthy roots are the foundation of long-term indoor plant care.
Feeding & Fertilizing Indoor Plants
Plants draw nutrients from soil over time, and eventually those nutrients need replenishing.
Best practices:
- Fertilize during the growing season (spring and summer)
- Use a balanced fertilizer designed for indoor plants
- Apply sparingly and according to instructions
Over-fertilizing can do more harm than good. When in doubt, feed less instead of more.
Repotting: When & Why It Matters
Repotting refreshes soil and gives roots space to grow. Here are some signs your plant may need repotting:
- Roots circling the bottom of the pot
- Water running straight through without absorbing
- Slowed growth during active seasons
Choose a pot only slightly larger than the current one. Oversized pots retain excess moisture and can destabilize root systems. Read more tips on choosing the right pot size for your plant.
Repotting is best done during spring or early summer, when plants are actively growing. Read all the basic do's and don'ts when repotting plants with this simple guide.
Ongoing Indoor Plant Maintenance
Indoor plant care doesn’t stop at watering or troubleshooting when issues arise. Regular maintenance includes:
- Removing yellow or damaged leaves
- Pruning leggy growth
- Dusting leaves so they can absorb light
- Rotating plants for even growth
These small actions keep plants healthy, balanced and visually refined, and can also help deter common houseplant pests.
Common Indoor Plant Problems (and What They Mean)
Plants communicate through their leaves.
- Yellowing leaves: Often overwatering or poor drainage
- Brown tips: Dry air, inconsistent watering, or salt buildup
- Drooping: Thirst, temperature stress, or root issues
- Slow growth: Insufficient light or nutrients
Observing changes early allows you to correct issues before they become serious.
Indoor Plant Care by Season
- Spring: Repot, fertilize, increase watering
- Summer: Maintain consistent moisture, monitor light
- Fall: Gradually reduce watering and feeding
- Winter: Minimal water, little to no fertilizer
Following a seasonal rhythm aligns your care with how plants naturally grow.
Indoor Plant Care Is About Balance
The best indoor plant care is calm, consistent, and intentional. When light, water, soil, and placement are right, plants largely take care of themselves.
Patience is part of the process. Let plants adjust. Observe before reacting. And remember: thriving indoor plants aren’t the result of perfection, but of patience and understanding!
