Understanding Your Calla Lily Plants
Before we get into the care routine, it helps to know what you are growing. Calla lilies are not true lilies. They belong to the Zantedeschia genus. This means they grow from rhizomes rather than bulbs, which affects how you plant and store them. Understanding this basic fact is the first step in learning how to care calla lily plants effectively.
Not Your Typical Lily
Because they are rhizomatous, they spread horizontally underground. This makes them great for dividing and sharing with friends. They also go through a natural dormancy period, unlike some other tropical houseplants. Respecting this rest period is the secret to getting them to bloom year after year.
Light Requirements for Calla Lilies
Light is fuel for your plants. Calla lily plants love sunshine, but they do not want to be scorched by it. In their natural habitat, they grow in dappled sunlight under taller vegetation. You want to mimic this environment as closely as possible.
Finding the Sweet Spot
If you are growing them outdoors, choose a spot that gets full morning sun but is shaded from the harsh afternoon rays. Too much direct sun will burn the leaves, causing them to turn yellow and crisp. If you are keeping them indoors, a bright windowsill with filtered light is perfect. Sheer curtains work great to diffuse strong sunlight.
How to Water Calla Lily Plants
Watering is where most plant parents go wrong. Calla lilies love moisture, but they hate sitting in water. The goal is to keep the soil evenly moist, like a wrung-out sponge.
The Golden Rule of Watering
Check the soil with your finger every few days. If the top inch feels dry, it is time to water. Pour water slowly over the soil until it runs out of the bottom of the pot. Always empty the drainage tray so the roots are not sitting in stagnant water.
Signs of Overwatering and Underwatering
Yellow leaves usually mean you are overwatering. Brown, crispy leaf edges often mean the plant is too dry. If your calla lily plants are looking droopy and sad, check the soil moisture first. Adjust your watering schedule based on the season—they need less water during their winter dormancy.
Soil and Fertilizer Needs
The right foundation makes all the difference. Calla lily plants need soil that holds moisture but drains well. Regular potting soil can sometimes be too heavy and retain too much water.
The Right Foundation
A high-quality potting mix with added perlite or sand is ideal. This creates air pockets in the soil and ensures excess water can escape. When planting rhizomes, place them about four inches deep with the eyes facing upward.
Feeding for Blooms
To get those gorgeous, long-lasting flowers, you need to feed your plants. Use a balanced liquid fertilizer every two weeks during the spring and summer. Once you see flowers forming, you can switch to a fertilizer higher in phosphorus to boost blooming. Stop feeding completely when the plant goes dormant in the fall.
Temperature and Humidity
Since calla lilies are native to warm climates, they prefer moderate temperatures. They thrive in conditions between 60 and 80 degrees Fahrenheit. They can handle a slight drop in temperature at night, but they are not frost-tolerant.
Creating the Perfect Climate
If you live in a cold area, you must bring your potted calla lilies indoors before the first frost. They also enjoy a bit of humidity. If your home is dry, especially in the winter, you can mist the leaves lightly or place the pot on a tray filled with pebbles and water.
The Dormancy Period: Crucial for Reblooming
This is the most important step that many beginners skip. You cannot force a calla lily to grow year-round. They need a rest period to recharge their energy for the next blooming season.
Why Rest is Essential
After the flowers fade and the leaves start to yellow in the fall, do not panic. This is the plant entering dormancy. Stop watering and let the foliage die back naturally. The plant is pulling nutrients back into the rhizome for storage.
Storing Rhizomes
If you live in a cold climate, you can dig up the rhizomes after the first frost. Brush off the dirt and let them dry for a few days. Store them in a paper bag filled with peat moss in a cool, dark place until spring. When it is time to wake them up, you will need to know how to repot a plant correctly to give them a fresh start.
Common Pests and Problems
Even the best-kept plants can face issues. Calla lily plants are generally hardy, but they can attract a few unwanted guests.
Battling Bugs
Aphids and spider mites are the most common pests. You can usually wash them off with a strong stream of water or treat the leaves with neem oil. Fungus gnats are also a risk if the soil stays too wet. If you notice tiny flies buzzing around, you should learn how to get rid of gnats in plants before they cause real damage to the roots.
Yellowing Leaves
Besides watering issues, yellow leaves can be a sign of nutrient deficiency. A good dose of fertilizer usually fixes this quickly. Always remove dead or dying leaves to keep the plant looking tidy and to prevent fungal diseases.
Are Calla Lilies Pet Friendly?
This is a critical question for pet owners. Unfortunately, calla lilies are toxic to cats and dogs. They contain calcium oxalate crystals that can cause oral irritation, drooling, and vomiting if ingested.
If you have curious pets, it is best to keep these plants completely out of reach. You might want to browse our list of plants not toxic to cats to find safer alternatives for your furry friends. Safety first!
Conclusion
Knowing how to care calla lily plants is all about balance. Give them plenty of bright, indirect light, keep their soil moist but not soggy, and feed them well during the growing season. Most importantly, respect their need for a winter dormancy. If you provide these basic needs, your calla lilies will reward you with stunning, elegant blooms year after year. Grab your gardening gloves, plant those rhizomes, and get ready for a gorgeous growing season!
Frequently Asked Questions
How often should I water my calla lily?
Water your calla lily when the top inch of soil feels dry to the touch. This is usually once or twice a week during the growing season, but always check the soil first to avoid overwatering.
Can calla lilies grow indoors?
Yes, calla lilies make excellent indoor plants! Just place them in a spot with bright, indirect sunlight and keep the soil consistently moist. They will thrive indoors as long as their basic needs are met.
Why are my calla lily leaves turning yellow?
Yellow leaves are usually a sign of overwatering or the natural dormancy period. If it is fall, the plant is naturally dying back. If it is spring or summer, cut back on watering and ensure the pot has good drainage.
Do calla lilies come back every year?
Yes, calla lilies are perennial rhizomes, meaning they will come back every year. They require a dormant period in the winter to rest and recharge before blooming again in the spring.
Should I cut off the dead flowers on my calla lily?
Yes, you should deadhead spent flowers. Snipping off the faded blooms prevents the plant from putting energy into seed production, which encourages it to produce more beautiful flowers instead.
How cold is too cold for calla lilies?
Calla lilies are not frost-tolerant and can be damaged by temperatures below 50 degrees Fahrenheit. If you live in a cold climate, you must dig up the rhizomes and store them indoors over the winter.
