Even if your lily has already seen better days, don’t worry.
We’ll show you how to bring it back to life.
Let’s dive in and help your lily thrive.
How to Keep a Lily Plant Alive Indoors
Keeping a lily plant alive indoors is absolutely doable, even if you’ve never had much luck with houseplants before.
The secret is to mimic the natural conditions your lily would enjoy in the wild.
Let’s break down the fundamentals of keeping a lily plant alive indoors.
1. Give Your Lily Bright, Indirect Light
One of the most important factors in how to keep a lily plant alive indoors is getting the light right.
Lilies love bright, filtered light, but direct sunlight can scorch their leaves and cause brown patches.
A spot near an east-facing window or a few feet away from a bright south-facing window is ideal.
If your lily isn’t getting enough light, you’ll notice the leaves turning pale green or yellow and the stems stretching toward the window.
Rotate your pot every few days so all sides of the plant get equal light.
You can also use sheer curtains to filter strong afternoon sun.
2. Water Consistently Without Overwatering
Water plays a huge role in your ability to keep a lily plant alive indoors.
The goal is to keep the soil evenly moist but never soggy.
Stick your finger into the top inch of soil, and if it feels dry, it’s time to water.
Always use a pot with drainage holes so excess water can escape.
Overwatering is one of the fastest ways to kill a lily plant indoors because it leads to root rot.
On the flip side, letting the soil completely dry out will cause the leaves to droop and wilt.
If you’re not sure whether to water, it’s better to wait an extra day than to water too soon.
3. Use the Right Potting Soil
The soil you choose can make or break your efforts to keep a lily plant alive indoors.
A light, airy potting mix that holds some moisture but drains well is perfect.
Look for a mix that contains peat moss, perlite, and maybe a little compost for nutrients.
Avoid heavy garden soil, which tends to compact and trap water around the roots.
Repotting your lily every year or two with fresh soil also keeps it healthy and gives the roots room to grow.
4. Keep Humidity and Temperature in the Sweet Spot
Lilies are tropical at heart, so they appreciate a little extra humidity in the air.
If your home is dry, especially in the winter months, you can set your pot on a tray of pebbles with water beneath it.
A small humidifier in the room also works wonders for keeping a lily plant alive indoors.
Try to maintain temperatures between 65 and 75 degrees Fahrenheit during the day.
Keep your lily away from drafty windows, heating vents, and air conditioners, as sudden temperature swings cause stress.
Common Mistakes That Kill Indoor Lily Plants
Even with the best intentions, people often make mistakes when they’re trying to keep a lily plant alive indoors.
Let’s look at the most common offenders so you can avoid them.
1. Watering Too Frequently
If you want to keep a lily plant alive indoors, you must resist the urge to water on a strict schedule.
Plants don’t need water every single day, and giving them too much is just as harmful as giving them too little.
Yellow leaves and mushy stems are classic signs that you’re overwatering your lily.
2. Placing Your Lily in Direct Sun
Direct sun might seem like a good idea, but it can actually cause serious damage to indoor lilies.
Brown, crispy patches on the leaves are a telltale sign of sunburn.
If you notice this happening, move your plant to a spot with filtered light.
This simple adjustment goes a long way toward keeping a lily plant alive indoors.
3. Forgetting to Feed Your Lily
Lilies need nutrients to stay strong and produce beautiful blooms.
If you never fertilize, your lily plant will slowly decline.
Use a balanced liquid fertilizer diluted to half strength every four to six weeks during the growing season.
Don’t fertilize in the winter when the plant is resting.
4. Using the Wrong Pot Size
Pot size matters more than you might think when it comes to keeping a lily plant alive indoors.
A pot that’s too large holds excess moisture, which can lead to root rot.
A pot that’s too small restricts root growth and dries out too quickly.
Choose a pot that’s about one to two inches larger than the root ball.
How to Encourage Blooms on an Indoor Lily
Keeping a lily plant alive indoors isn’t just about survival, it’s about helping it thrive and flower.
Here’s how to get your lily to show off its beautiful blooms.
1. Provide a Period of Cooler Temperatures
Many lilies need a period of cooler rest to trigger blooming.
In the winter, move your lily to a cooler room with temperatures around 50 to 55 degrees Fahrenheit.
This rest period mimics the natural seasonal cycle and encourages the plant to bloom in the spring.
2. Deadhead Spent Blooms
When flowers fade, remove them promptly to encourage more blooms.
This process, called deadheading, directs the plant’s energy into producing new flowers instead of seeds.
Just snip the spent bloom off at the base of the stem.
You can also cut the entire stalk back to the base once all its blooms have faded.
3. Keep the Leaves Clean
The leaves of your lily plant are like solar panels for the plant.
Dust that accumulates on the leaves can block light and reduce the plant’s ability to photosynthesize.
Wipe the leaves gently with a damp cloth every couple of weeks.
It’s a small task that makes a big difference.
So, How Do You Keep a Lily Plant Alive Indoors?
You can keep a lily plant alive indoors by giving it bright, indirect light, watering consistently, using well-draining soil, and maintaining good humidity levels.
Avoid the common mistakes of overwatering, direct sun, and forgetting to feed your plant.
With a little attention and care, keeping a lily plant alive indoors is totally achievable.
Your reward will be glossy green leaves and those gorgeous, fragrant blooms.
So go ahead and give your lily the love it deserves.
