Understanding Light Requirements
Light is the most important factor in plant health. Without enough of it, even the best soil and watering routine won’t help
Types of Light for Houseplants
- Low Light: Suitable for snake plants, pothos, and ZZ plants. Place them a few feet away from north-facing windows.
- Medium Light: Perfect for peace lilies and philodendrons. Indirect sunlight works best.
- Bright Indirect Light: Ideal for monsteras, fiddle leaf figs, and calatheas. Place near east or west-facing windows.
- Direct Sunlight: Succulents and cacti thrive in south-facing windows with several hours of full sun.

Watering Houseplants the Right Way
Overwatering is the #1 cause of plant problems. Here’s how to do it correctly:
General Rules
- Always check soil moisture before watering. Stick your finger 1–2 inches into the soil. If it’s dry, it’s time to water.
- Use pots with drainage holes to prevent root rot.
- Adjust watering frequency based on season—plants need less water in winter.
Signs of Overwatering
- Yellowing leaves
- Mushy stems
- Moldy soil
Signs of Underwatering
- Crispy leaf edges
- Drooping stems
- Soil pulling away from the pot edges
Our Moisture Meter Tools make watering easier by removing the guesswork.
Choosing the Right Soil
Soil is more than just dirt—it’s the foundation of plant health.
Types of Potting Mix
- All-Purpose Mix: Great for most tropical houseplants.
- Cactus & Succulent Mix: Fast-draining, sandy soil for desert plants.
- Aroid Mix: Chunky mix with bark, perlite, and moss for monsteras and philodendrons.
- Orchid Mix: Extra airy, usually bark-based.
Soil Tips
- Avoid garden soil—it compacts easily indoors.
- Refresh soil every 12–18 months to prevent compaction and nutrient depletion.
- Add perlite for extra aeration.

Temperature and Humidity
Most houseplants come from tropical regions, so they love warmth and humidity.
- Temperature: Keep between 65–75°F (18–24°C). Avoid drafts and sudden temperature changes.
- Humidity: Aim for 40–60%. Dry air causes crispy leaves.
How to Increase Humidity
- Group plants together.
- Use a humidifier.
- Place plants on a pebble tray with water.

Pruning and Cleaning Houseplants
Pruning keeps your plants healthy and looking their best.
Benefits of Pruning
- Encourages new growth.
- Prevents pests and disease.
- Shapes the plant for better aesthetics.
Cleaning Leaves
- Dust blocks photosynthesis.
- Wipe leaves gently with a damp cloth every 2–3 weeks.
Repotting Houseplants
Repotting isn’t just about aesthetics—it keeps roots healthy.
Signs It’s Time to Repot
- Roots poking out of the drainage holes.
- Soil dries out too quickly.
- Plant is top-heavy or outgrowing its pot.
How to Repot (Step-by-Step)
- Choose a pot 1–2 inches larger.
- Remove plant gently from old pot.
- Trim dead roots.
- Add fresh soil.
- Water thoroughly.

Fertilizing Houseplants
Fertilizer = plant food. Without it, soil becomes depleted.
Fertilizer Basics
- Spring & Summer: Feed every 4–6 weeks.
- Fall & Winter: Reduce feeding—plants grow slower.
Types of Fertilizer
- Liquid Fertilizer: Easy to apply during watering.
- Slow-Release Fertilizer: Granules that feed for months.
- Organic Fertilizer: Seaweed extract, worm castings, or compost.
Preventing and Treating Pests
Bugs happen—even in the cleanest homes.
Common Houseplant Pests
- Aphids
- Mealybugs
- Spider mites
- Fungus gnats
- Scale insects
Natural Pest Control Methods
- Neem Oil spray for most pests.
- Sticky Traps for fungus gnats.
- Isolate New Plants before introducing them to your collection.

Troubleshooting Houseplants
Even with the best care, plants can show stress. Here’s what to do:
- Yellow Leaves → Likely overwatering or lack of nutrients.
- Brown Tips → Low humidity or too much fertilizer.
- Drooping Leaves → Check watering schedule and root health.
- Slow Growth → Not enough light or nutrients.

Frequently Asked Questions (FAQ)
Q1: How often should I water my houseplants?
It depends on the plant, but most houseplants prefer watering when the top 1–2 inches of soil are dry.
Q2: What type of soil is best for houseplants?
Tropical plants thrive in a well-draining, peat or coco coir-based mix with perlite. Succulents need sandy, fast-draining soil.
Q3: How do I increase humidity for my plants?
Use a humidifier, pebble tray, or group plants together to create a mini greenhouse effect.
Q4: Do houseplants need fertilizer?
Yes—fertilizer replaces nutrients that deplete from soil over time. Use during spring and summer when plants are actively growing.
Q5: Why are my houseplant’s leaves turning yellow?
The most common causes are overwatering, lack of light, or nutrient deficiencies.
