Peace lilies are one of the most beloved houseplants.
Their elegant white blooms and deep green leaves bring a touch of serenity to any home.
But as winter transitions into spring, your peace lily may need a little extra care to prepare for the growing season.
March is the perfect time to refresh your plant’s environment, adjust watering habits, and ensure it thrives in the months ahead.
This guide will walk you through everything you need to know about caring for your peace lily in March.
Let’s get started.
Check for Winter Stress
Winter can be tough on peace lilies.
Cold temperatures, dry indoor air, and lower light levels can leave your plant looking a little worn out.
Start by checking for signs of stress.
If your peace lily’s leaves are yellowing, wilting, or developing brown tips, it may be recovering from winter struggles.
If your plant was near a drafty window or heating vent, it may have suffered from temperature fluctuations.
Now that March has arrived, move it to a more stable location with indirect sunlight and consistent warmth.
If you notice any dead or damaged leaves, trim them off with clean scissors to encourage new growth.
Water Wisely as Temperatures Rise
March brings slightly warmer temperatures, meaning your peace lily will start to use more water.
But before you reach for the watering can, remember that peace lilies hate being overwatered.
Too much water can lead to root rot, one of the biggest threats to a peace lily’s health.
Check the soil before watering by sticking your finger about an inch deep into the pot.
If it feels dry, it is time to water.
If it still feels moist, wait a few more days.
When watering, pour slowly and evenly until you see water drain from the bottom of the pot.
Make sure to empty any excess water from the saucer to prevent soggy roots.
Your peace lily prefers filtered or distilled water, as tap water with chlorine and fluoride can cause leaf browning.
If you only have tap water, let it sit overnight before using it.
Boost Humidity for Healthier Leaves
Peace lilies love humidity, and March is the time to start increasing moisture in the air.
Indoor heating during winter can dry out the air, leaving your plant’s leaves crispy or curling at the edges.
To boost humidity, you can mist your peace lily’s leaves lightly every few days.
Another great option is placing a humidity tray under the plant.
Simply fill a shallow tray with pebbles and water, then set your peace lily’s pot on top.
As the water evaporates, it will create a humid microclimate around the plant.
If you have several houseplants, grouping them together can also increase humidity naturally.
Find the Perfect Spot for Optimal Light
March brings longer days, which means more natural light.
Peace lilies thrive in bright, indirect light, but too much direct sun can scorch their leaves.
Find a spot near a north- or east-facing window where your plant can enjoy gentle morning light.
If you notice your peace lily stretching or growing leggy, it may need more light.
On the other hand, if the leaves are developing brown spots, they might be getting too much direct sun.
If your home does not get a lot of natural light, you can supplement with a grow light for a few hours a day.
This will encourage healthier, more compact growth and better blooming.
Feed Your Peace Lily for Strong Spring Growth
March marks the beginning of the growing season, making it the perfect time to start fertilizing.
But peace lilies do not need heavy feeding.
Too much fertilizer can lead to salt buildup in the soil, causing leaf burn.
Use a balanced liquid houseplant fertilizer, diluted to half strength, once a month.
A 10-10-10 or 20-20-20 fertilizer works well.
If you prefer an organic option, try compost tea or a mild fish emulsion.
Fertilizing in early spring will encourage stronger growth and more blooms in the months ahead.
Give Your Plant a New Home If Needed
Peace lilies usually need to be repotted every two to three years, and March is a great time to check if your plant needs a new home.
If roots are growing out of the drainage holes, the soil is drying out too quickly, or the plant seems root-bound, it is time for a larger pot.
Choose a pot that is about one to two inches wider than the current one.
Make sure it has good drainage holes to prevent excess moisture from sitting in the bottom.
Use a well-draining potting mix, preferably one designed for houseplants.
To repot, gently remove your peace lily from its current container, shake off excess soil, and inspect the roots.
Trim any rotting or mushy roots before placing the plant in its new pot.
Fill in with fresh soil, press it down lightly, and water thoroughly to help the plant settle in.
Keep the Leaves Clean and Shiny
Dust can accumulate on peace lily leaves, making it harder for them to absorb light.
Since March is the start of a new growing season, it is a great time to give your plant a fresh start.
Use a damp cloth to wipe each leaf gently, removing dust and dirt.
For a deeper clean, you can rinse the plant under a lukewarm shower for a few minutes.
Just be sure to let the leaves dry completely before placing the plant back in its usual spot.
Keeping the leaves clean improves photosynthesis and overall plant health.
Stay Ahead of Pests Before They Spread
Pests can become more active as the weather warms up.
Common peace lily pests include spider mites, mealybugs, and aphids.
Check under the leaves and near the soil for any signs of tiny bugs, sticky residue, or webbing.
If you spot pests, wipe the leaves with a damp cloth and use a mixture of water and a few drops of neem oil to keep them at bay.
For mealybugs, dabbing them with rubbing alcohol on a cotton swab can help eliminate them.
Keeping your plant clean and well-ventilated will prevent most pest problems before they get out of control.
Help Your Peace Lily Bloom Again
Peace lilies are known for their elegant white blooms, but they do not always flower on schedule.
If your plant has not bloomed in a while, March is the time to start encouraging it.
Make sure your peace lily is getting enough indirect light and has been fertilized with a phosphorus-rich fertilizer.
If conditions are right, you should start seeing flower stalks emerging in a few weeks.
Just be patient.
Peace lilies do not bloom constantly and usually flower in cycles.
Rotate for Balanced, Even Growth
Peace lilies grow toward the light, so if you keep them in the same position for too long, they may start leaning.
To keep your plant balanced and symmetrical, rotate the pot every couple of weeks.
This ensures all sides receive equal exposure to light and helps the plant grow evenly.
Let Your Peace Lily Settle Without Overhandling
While it is tempting to fuss over your peace lily now that spring is arriving, it is best to let it adjust naturally.
Once you have checked for winter stress, adjusted watering, and possibly repotted, give your plant time to settle.
Peace lilies are resilient and will reward you with steady growth and beautiful foliage if you allow them to adapt to their environment.
Final Thoughts
March is the perfect time to refresh your peace lily’s care routine and prepare it for a season of healthy growth.
By checking for winter stress, adjusting watering, increasing humidity, and fertilizing wisely, you can ensure your plant stays vibrant and strong.
With the right care, your peace lily will reward you with lush green leaves and, hopefully, stunning white blooms.
Take the time to give your plant some extra attention this month, and enjoy watching it thrive throughout the year.
