You can care for calla lilies indoors by giving them bright, indirect light, consistent moisture, and a period of rest after they bloom.
Caring for calla lilies indoors is simpler than many people think, as long as you understand their natural growth cycle and what they need to thrive inside your home.
If you’ve been wondering how to care for calla lilies indoors without killing them, the good news is that these elegant plants are quite forgiving once you get the basics right.
In this post, we’ll walk through everything you need to know about how to care for calla lilies indoors, from watering and lighting to dormancy and common problems.
Let’s dig in and get your calla lilies blooming beautifully inside.
Why Calla Lilies Can Thrive Indoors
Calla lilies can thrive indoors because they adapt well to container life when their needs are met.
These plants originate from South Africa, where they grow in marshy areas that get plenty of sunlight and moisture.
When you bring them inside, you’re essentially recreating those conditions on a smaller scale.
The key to learning how to care for calla lilies indoors is recognizing that they are not typical houseplants like succulents or snake plants.
They have a bulb-like rhizome that stores energy, and they follow a distinct cycle of growth, bloom, and dormancy.
Understanding this cycle makes indoor calla lily care much more straightforward and rewarding.
1. Light Is the Foundation of Indoor Calla Lily Care
Light is the most critical factor when you’re figuring out how to care for calla lilies indoors.
These plants crave bright, indirect sunlight for at least six hours a day.
A south or west-facing window is usually perfect, but you’ll want to filter the harsh afternoon sun with a sheer curtain.
If you don’t have enough natural light, you can supplement with a grow light placed about 12 inches above the plant.
Too little light will result in leggy growth and few or no flowers, so this is non-negotiable for healthy calla lilies indoors.
2. Watering Needs Are Different Than Most Houseplants
Watering is where most people struggle with calla lily indoor care.
Unlike many houseplants that prefer to dry out between waterings, calla lilies like consistently moist soil.
You should water your calla lily whenever the top inch of soil feels dry to the touch.
This usually means watering every two to three days during the active growing season.
However, you must avoid waterlogging the soil, as soggy conditions can rot the rhizome.
Make sure your pot has drainage holes, and never let the pot sit in standing water for more than a few minutes.
The perfect balance for calla lilies indoors is moist but not soaking wet soil at all times.
3. Temperature and Humidity Keep Calla Lilies Happy
Temperature and humidity play a big role in how to care for calla lilies indoors successfully.
These plants prefer daytime temperatures between 65°F and 75°F, which matches most indoor environments perfectly.
At night, they can tolerate a slight drop to around 60°F, but avoid cold drafts from windows or air conditioning vents.
Calla lilies also appreciate moderate humidity, around 50% or higher.
If your home is dry, especially in winter, you can mist the leaves regularly or place a small humidifier nearby.
You can also set the pot on a tray filled with pebbles and water, which increases humidity around the plant.
4. Feeding Your Calla Lily for Strong Blooms
Fertilizing is an essential part of indoor calla lily care that many beginners overlook.
During the active growing season, which runs from spring through early summer, feed your calla lily every two weeks.
Use a balanced liquid fertilizer diluted to half strength, such as a 10-10-10 formulation.
Once the plant starts forming flower buds, you can switch to a fertilizer higher in phosphorus to encourage more blooms.
Stop fertilizing completely once the leaves begin to yellow and the plant enters dormancy.
Overfeeding can cause salt buildup in the soil, which can damage the roots, so always follow the label instructions.
How to Care for Calla Lilies Indoors Through Dormancy
How to care for calla lilies indoors changes dramatically after the blooming period ends.
Many people throw their calla lilies away when the flowers fade, but that’s a mistake because these plants can return year after year.
Understanding the dormancy phase is crucial for long-term success.
1. Trigger the Rest Period
After your calla lily finishes blooming, the leaves will start to yellow and wither.
This is a natural signal that the plant is preparing to go dormant, not that it’s dying.
When you see this happening, gradually reduce watering over the next couple of weeks.
Once the foliage has completely died back, stop watering altogether.
The soil should be allowed to dry out completely, and the pot should be moved to a cool, dark location.
A basement or garage with temperatures around 50°F to 55°F is ideal for this resting phase.
2. Store the Rhizome or Pot
You have two options when it comes to dormancy: leave the rhizome in its pot or dig it up and store it separately.
If you leave it in the pot, simply keep it in that cool, dark spot for two to three months.
If you prefer to remove the rhizome, carefully lift it from the soil, brush off excess dirt, and let it dry for a few days.
Then store the rhizome in a paper bag filled with peat moss or sawdust.
Make sure it’s kept dry and cool, checking periodically for any signs of rot or mold.
3. Wake Your Calla Lily Back Up
After the rest period, it’s time to bring your calla lily back to life.
If the rhizome was stored separately, plant it in fresh, well-draining potting mix with the pointed side facing up.
Place the pot back in a bright location and start watering lightly.
Within a few weeks, you should see new shoots emerging from the soil.
This is the perfect time to resume your regular indoor calla lily care routine with light, water, and fertilizer.
Common Problems in Indoor Calla Lily Care
Even when you know how to care for calla lilies indoors, problems can still arise.
Here are the most common issues you might encounter and how to fix them.
1. Yellowing Leaves
Yellow leaves usually indicate either overwatering or the beginning of natural dormancy.
If the soil feels soggy and the plant is still actively growing, you’re watering too much.
Let the soil dry out slightly before watering again.
If the leaves are yellowing after blooming, it’s simply the plant entering dormancy, which is perfectly normal.
2. No Flowers
A calla lily that doesn’t bloom indoors is often suffering from insufficient light.
Move it to a brighter spot or add a grow light.
Another culprit is lack of dormancy, as these plants need that rest period to recharge and produce flowers.
Also, make sure you’re not overfertilizing with nitrogen, which promotes leaves over blooms.
3. Pests Like Spider Mites and Aphids
Indoor calla lilies can attract spider mites, especially in dry air.
These tiny pests cause stippling on leaves and fine webbing.
Wipe the leaves with a damp cloth and increase humidity to deter them.
Aphids can also appear, usually on new growth and flower buds.
Rinse them off with a gentle spray of water or treat with insecticidal soap.
So, How to Care for Calla Lilies Indoors
So, how to care for calla lilies indoors is all about balancing light, water, and their natural growth cycle.
You can care for calla lilies indoors successfully by providing bright indirect light, consistent moisture, and a cool, dry dormancy period.
Once you master these basics, your calla lilies will reward you with elegant blooms year after year.
Whether you’re a seasoned plant parent or a newbie, this indoor calla lily care routine is entirely doable with a little patience and attention.
Now you have the knowledge, so go ahead and enjoy the beauty of calla lilies inside your home.
