How To Care For Your Peace Lily

Some gardeners prefer to grow their veggies, herbs, and fruits, while others focus on flowering plants to accentuate their indoor and outdoor spaces. One of the most popular and easiest houseplants is the peace lily. With its waxy, white blossoms and deep green leaves, this tropical beauty is a sight to behold in all its glory!

However, with inadequate care and maintenance, they can go from being perky to droopy in a matter of days. Your peace lily plant can be picky at times, but if you know how to care for them, it makes for a stunning focal point of your home.

Below you’ll learn how to care for your peace lily plant to help it thrive. 

How to Care for Your Peace Lily

It takes a combination of things to raise a plant. From lighting, soil, and choosing the right containers to watering schedules, fertilizers, and temperature requirements, here’s what you should remember.

Note: Peace lily plants contain insoluble calcium oxalates, which are toxic to cats and dogs and mildly toxic to humans. Please keep your peace lily plants away from children and pets to avoid accidental ingestion.

1. Lighting

Peace lilies thrive on indirect sunlight. If your peace lily’s leaves are turning brown or yellow, place it away from direct sunlight and onto a window that receives plenty of indirect sunlight, morning sunlight, and air.

An east or north-facing window is great because they’re cooler than southern or western windows that absorb high amounts of radiant heat. Also, the sun in the morning isn’t as hot as the mid-day or afternoon sun, which also means that your plant will have less water loss, leading to less frequent watering.

2. Potting Soil

Peace lilies prefer well-aerated, light mixes that drain well and retain a little moisture because these plants hate wet feet. Your potting mix should include good amounts of perlite, charcoal, orchid bark, and other similar materials to keep the soil well-aerated to prevent root rot.

If you think your plant is a victim of root rot, you can use household items to eliminate it. As for the soil pH, it will thrive in somewhat acidic to neutral soil of 5.0 to 6.5. You can refresh old potting soil if you have some lying around at home from last year.

3. Choosing the Right Container

Remember, peace lilies don’t like wet feet, so the container you pick should have drainage holes to avoid water buildup around your plant’s roots. Overwatering can cause yellow leaves, droopy or curled leaves, and mushy stems that can kill your plant if not rectified. If your plant’s pot is made of unglazed clay or cement, it will wick out the extra moisture from the potting soil.

Remember, plants in clay pots will dry faster than plants growing in plastic pots. Your watering schedule will also depend on the container material (clay, plastic, recycled plastic, fiberglass, cement) you choose to work with.

Don’t let your pot sit in saucers filled with water, as this will cause a build-up of excessive amounts of soluble salts that can burn your plant’s roots. If it’s a design aspect, fill your saucer with pebbles of your choice and place your pot on top of the bed of pebbles to aid drainage and prevent root burn.

4. Watering Schedule

Peace lilies love moisture. You can water them frequently, provided that the soil they’re growing in is well-draining. Underwatering can also cause brown and droopy or curled leaves, so you must strike a balance to keep your plant healthy.

It’s always a good idea to test your soil’s moisture before watering your plant to ensure you’re not drowning its roots. Invest in a good soil moisture tester to see if your plant needs a drink to avoid under and overwatering.

Besides maintaining a watering schedule and testing your soil’s moisture, water quality also plays a crucial role in plant health. If you spot brown tips on your plants, the water you’re using contains too much fluoride and chlorine.

While you can’t do much about fluoride, you can remove the water’s chlorine content by boiling it for half an hour and letting it cool before using it to water your plants.

5. Fertilizers

Peace lilies require light fertilizing during their active growing season. You should use organic fertilizer, dilute it slightly (one-fourth of the recommended dosage), and add it to the soil every 2-3 weeks.

One of the most common mistakes gardeners make is overfertilizing their plants. When it comes to fertilizers, less is more. When you overfertilize your plants, you cause the soil to have an excessive amount of salt buildup that burns the plant’s roots by severely dehydrating them.

To remove excessive amounts of salt, flush the soil with plenty of rainwater, about two to three times the volume of the pot. You can even place your pot in the sink, open the tap, and let a gentle stream of water run through the plant’s soil for a few minutes.

Pro-Tip: Smaller pots require less fertilizer because they contain less soil.

6. Humidity and Temperature Requirements

If your plant has brown leaves, brown tips, or green flowers (that aren’t about to bloom or die), you need to check your plant’s humidity levels. You can invest in a good-quality humidifier, use a humidity tray, or place your peace lily pot on a shallow pebble tray filled with water, to improve your plant’s humidity levels.

You can even mist your plant frequently to improve humidity levels. The best temperature to grow peace lilies is between 65 to 85 degrees Fahrenheit.

7. Other Requirements

Photosynthesis starts when your plants receive sunlight. If your peace lily’s receiving the morning sun, the leaves must be prepared to absorb the rays, but this won’t happen if your leaves are covered in dust.

Carefully examine your plant; if the leaves are dusty, wipe them gently with a large wet paper towel so the dust doesn’t affect photosynthesis.

Peace lilies require well-aerated, well-draining, and light soil. And while the easiest thing would be to purchase the best potting mix if you only have a plant or two, mixing your own potting soil is the ideal option for you if you’re dealing with multiple plants, as this will help you save up money in the long run.

In a large container or on a stretched-out tarp, add the following ingredients:

  • 5 parts of orchid bark
  • 4 parts of coco coir
  • 5 parts of perlite
  • 2 parts of worm castings
  • 2 parts of activated charcoal

Mix all these ingredients thoroughly and use them as your potting mix for repotting or transplanting peace lily plants.

Diffusing Tropical Vibes

Peace lilies are some of the most popular house plants among gardeners. They’re stunning with their gorgeous green leaves and glossy white flowers that complement almost every type of interior design.

While hardy, they require special care and plenty of TLC to thrive. Unfortunately, you have to be careful if you have pets around since peace lilies are toxic for them.
