Peace lilies are more than just a pretty face. They’re actually tropical plants that originally come from the rainforest. And aside from looking great they also do their bit by purify your air.
But like any living thing they need a bit of TLC to truly thrive.
In this guide we’ll dig deep (but not too literally!) into everything you need to know about caring for your peace lily indoors.
Understanding Peace Lilies
What Makes a Peace Lily Unique?
The peace lily isn’t actually a lily at all. It belongs to the Araceae family, making it a relative of the philodendron. Its iconic white “flowers” are technically modified leaves called spathes, which surround a spiky structure called the spadix.
Beyond their good looks peace lilies are excellent natural air purifiers. They can remove toxins like benzene and formaldehyde from the air. So are a great choice for any room in your home.
Native Habitat
In the wild peace lilies grow under the dense canopies of tropical rainforests. This means they’re used to filtered light, high humidity and consistently warm temperatures. Being aware of their natural habitat can help us to mimic these conditions indoors.
With that in mind let’s look at how and here to grow your peace lily.
The Perfect Spot for Your Peace Lily
How Much Is Too Much Light?
Peace lilies are adaptable. But they have clear preferences when it comes to light:
- Bright, indirect light: A spot near an east-facing window works wonders.
- Avoid direct sun: Harsh rays can scorch their leaves.
- Low-light tolerance: If your home is dim a peace lily will survive. But don’t expect it to bloom frequently.
Pro Tip: Rotate your peace lily every few weeks to get even growth. Plants tend to lean towards their light source so this keeps them looking balanced. Otherwise you might end up with a leaning lily!
Temperature and Placement
Peace lilies love consistency:
- Ideal range: 65–80°F (18–27°C).
- Avoid cold drafts: Keep them away from frequently opened doors or windows during the winter.
- Don’t overheat: Proximity to heaters can dry them out.
Boosting Humidity Levels
Being tropical peace lilies crave moisture:
- Humidifier: Place one nearby during winter when indoor air tends to be dry.
- Pebble tray: Fill a shallow tray with water and pebbles and place the pot on top.
- Grouping plants: Placing several plants close together naturally increases humidity.
Watering
How to Water a Peace Lily
Peace lilies are sensitive to both overwatering and underwatering. Strike the perfect balance by following these steps:
- Check the soil: Insert your finger about an inch into the soil. If it’s dry, it’s time to water.
- Use filtered or distilled water: Chlorine and fluoride in tap water can harm the plant.
- Water thoroughly: Pour water until it drains from the bottom making sure there is even moisture.
Signs You’re Overdoing It
- Yellow leaves: Too much water can lead to root rot which shows as yellowing foliage.
- Mushy stems: This is a clear indicator of waterlogged roots.
What Happens When It’s Too Dry?
- Drooping leaves: Peace lilies are dramatic and will visibly droop when thirsty.
- Crispy leaf edges: Chronic underwatering can cause brown, brittle edges.
Feeding Your Peace Lily
When and What to Feed
Peace lilies aren’t heavy feeders but they do benefit from occasional nourishment:
- Frequency: Every 6–8 weeks during spring and summer.
- Fertilizer type: A balanced liquid fertilizer (e.g., 10-10-10) diluted to half strength.
Common Feeding Mistakes
- Over-fertilization: Can cause a buildup of salts in the soil which leads to browning leaf tips.
- Winter feeding: Peace lilies rest during colder months so hold off until spring.
Soil and Repotting
Choosing the Right Soil
Peace lilies thrive in light, well-draining soil:
Ideal mix: A blend of peat moss, perlite and potting soil.
Avoid heavy soils: Dense mixes retain too much water and can cause root issues.
Repotting Basics
When to repot: Every 1–2 years or when the roots begin circling the pot.
How to repot:
- Gently remove the plant from its pot.
- Tease apart the roots and trim any that look damaged.
- Place the plant in a new pot about 1–2 inches wider than the old one.
Pruning and Maintenance
Keeping It Clean
Dust can accumulate on peace lily leaves interfering with the photosynthesis:
Wipe with a damp cloth: Avoid using commercial leaf shine products as they can clog pores.
Pruning Dead Leaves
- Snip yellow or brown leaves: Use sharp, sterilized scissors.
- Cut at the base: Trim as close to the soil line as possible.
Why Isn’t My Peace Lily Flowering?
If your peace lily isn’t producing any of its trademark white flowers then it may need:
Better light: Try moving it closer to an east-facing window.
More nutrients: Regular feeding during the growing season supports blooms.
Age: Young plants may need a year or two to mature before flowering.
Troubleshooting Common Problems
Leaf Issues
| Symptom | Cause | Solution |
|---|---|---|
| Yellowing leaves | Overwatering | Let the soil dry out before the next watering. |
| Brown tips | Low humidity or over-fertilizing | Increase humidity or cut back on fertilizer. |
| Drooping leaves | Underwatering or temperature stress | Water thoroughly or move to a stable location. |
Pest Problems
- Spider mites: Tiny, web-spinning pests that thrive in dry conditions.
- Mealybugs: Cottony white bugs often found in leaf crevices.
How to Combat Pests:
1. Wipe leaves with a mixture of water and mild soap.
2. Use neem oil as a natural pesticide.
Propagation Made Simple
Dividing Peace Lilies
Propagation by division is actually very straightforward:
- Remove the plant from its pot.
- Gently separate the root clumps making sure each has its own leaves and roots.
- Replant divisions in fresh soil and water thoroughly.
Safety Considerations for Pets and Kids
Peace lilies contain calcium oxalate crystals. These can irritate mouths and throats if ingested. So it’s best to keep the plant out of reach of pets and children.
Fun Tips and Tricks
Use rainwater: It’s a great alternative to tap water and closely mimics the natural hydration peace lilies enjoy in the wild.
Accessorize with pots: A decorative pot can elevate your plant’s aesthetic appeal while hiding the practical plastic grower’s pot.
Peace lily bouquet: Their blooms can be cut and displayed in vases for up to 10 days.
By following this guide you’ll give yourself the best chance of having a healthy peace lily. Whether you already have experience growing then or you’re a first-timer, peace lilies are a joy to grow.
