AdewebsIf you’ve ever stood in front of a row of calla lilies in full bloom, you know how they can stop you in your tracks. Those trumpet shaped flowers standing tall on graceful stalks look like something you’d see on a wedding aisle or a painted canvas. But here’s the secret: they’re not just for florists. With a little patience and know-how, you can grow calla lilies in your own garden or in pots on the porch and enjoy blooms that look like they came straight from a bouquet shop.
When I first started growing calla lilies on my farm, I thought they were high maintenance. I’d seen them in fancy arrangements and assumed they needed greenhouse conditions to survive. I was wrong. They’re surprisingly forgiving if you respect their needs for moisture, soil, and a good rest period. The first time I saw my patch explode into bloom, it felt like winning a quiet little lottery.
That’s why I wanted to write this guide. Whether you’ve only admired calla lilies in photos or you’ve tried growing them and struggled with calla lily yellow leaves turning yellow, I’ll share everything I’ve learned over the seasons. This isn’t a corporate how-to, just the voice of someone who’s planted, watered, fed, and sometimes lost calla lilies, and then tried again.
Understanding the Calla Lily
Calla lilies aren’t true lilies at all. They’re more like tender perennials that sprout from rhizomes. In their native South African habitat, they grow in marshy ground with bright but filtered light. That tells us a lot about how to treat them at home. If you can mimic that mix of moisture, warmth, and light, you’ll get healthy foliage and stunning blooms.
Choosing the Right Variety
Calla lilies come in a rainbow of colors. The classic white ones are elegant, but hybrids in pink, yellow, orange, purple, and even almost black can bring drama to your garden. I like to mix a few in the same bed for a painter’s palette effect. If you’re new to them, start with the sturdy white ‘Aethiopica’ or the buttery ‘Golden Calla’—they’re reliable bloomers.
Planting Time and Location
Think of calla lilies as sun lovers that also like cool feet. In temperate climates, plant the rhizomes in spring after frost danger has passed. Pick a spot with morning sun and afternoon shade, or bright filtered light all day. If you’re growing in pots, use a deep container with drainage holes.
Soil Preparation
This is where many people go wrong. Calla lilies hate heavy, compacted soil. Mix in plenty of compost, leaf mold, or fine bark to create a loose, rich bed. In pots I use equal parts peat free compost, perlite, and aged manure. Good soil not only helps roots breathe but also prevents rot.
Planting Depth
Plant the rhizomes about 3 inches deep with the growing points facing up. Space them 8–12 inches apart if you’re planting a cluster. Don’t crowd them—give each plant room to spread. Water well after planting to settle the soil.
Watering the Right Way
Here’s where experience counts. Calla lilies like moisture, but not soggy feet. In the active growing season, keep the soil consistently damp. In pots that means checking every few days. On the farm I use drip lines so the water seeps slowly into the root zone. If you see calla lily yellow leaves turning yellow during bloom time, it’s often a sign of either overwatering or poor drainage. Let the soil dry slightly between waterings but never let it become bone dry.
Feeding for Blooms
I feed my calla lilies lightly but regularly. A balanced fertilizer every 3–4 weeks during growth works wonders. Too much nitrogen will give you lush leaves but few flowers. Look for a bloom booster with more phosphorus if you want those big, colorful trumpets.
Mulching and Weeding
A thin layer of mulch helps hold moisture and keeps weeds down. Just don’t pile it right against the stems or you’ll risk rot. In my beds I use shredded leaves or straw. In pots you can use fine bark chips.
Supporting Tall Stems
Some calla lilies, especially the taller varieties, can flop when blooms are heavy. I sometimes stake them gently or use small wire supports hidden among the leaves. It’s a small effort for a big payoff when those blooms stand tall and proud.
Handling Yellow Leaves
Let’s talk about that common issue—calla lily yellow leaves turning yellow. Sometimes it’s normal. As the plant goes into dormancy after flowering, the leaves naturally yellow and die back. But if it happens during active growth, check your watering, drainage, and feeding. Also make sure the plant isn’t stressed by too much direct midday sun. Adjust one thing at a time and watch the response.
Encouraging More Blooms
Want a longer bloom season? Keep removing spent flowers to redirect energy back into new buds. Deadheading not only tidies the plant but also prolongs flowering. After the bloom cycle ends, reduce watering and let the plant rest.
Dormancy and Overwintering
Calla lilies need a rest period to recharge. In warm zones, they may go semi dormant in the ground. In cooler climates, dig up the rhizomes after the leaves die back. Shake off soil, let them dry for a few days, then store in a cool, dry place in peat free moss or sawdust until spring. In pots you can simply move the container to a frost free spot and cut back on watering.
Growing Calla Lilies in Containers
Container growing gives you more control over soil and moisture. Choose a pot at least 12 inches deep. Use a rich, well draining mix and water consistently. In summer I keep my pots on the porch where they get bright light but no harsh afternoon sun. The blooms last longer and colors stay vivid.
A Relatable Scenario
Last year a neighbor visited my farm and admired a big pot of golden calla lilies by my barn door. She said she’d tried growing them three times and always ended up with yellow leaves and no flowers. We walked over to her yard, and sure enough, her pots were filled with heavy garden soil that stayed soggy after every rain. We repotted one together using a lighter mix, moved it to a brighter but not scorching spot, and within two months she had her first blooms. That’s the magic of small adjustments.
Common Problems and Quick Fixes
-
Yellowing Leaves During Growth: Check for overwatering, poor drainage, or too much sun.
-
No Flowers: Too much nitrogen or not enough light. Switch to a bloom booster and move to brighter spot.
-
Rhizome Rot: Soil too wet or planted too deep. Replant in a lighter mix.
-
Pests: Aphids and spider mites can show up. A quick spray of insecticidal soap usually handles them.
How-To: Propagating Calla Lilies
-
Wait until dormancy.
-
Dig up the clump and gently separate rhizomes.
-
Check each piece for healthy buds.
-
Replant or store for the next season.
This is an easy way to multiply your plants and share with friends.
How-To: Forcing Calla Lilies Indoors
Want winter blooms? Pot up healthy rhizomes in fresh soil about 8 weeks before you want flowers. Keep them in a bright, warm spot and water sparingly until growth starts. Increase watering once leaves appear. It’s like having a piece of summer in your living room during the cold months.
FAQs
Why are my calla lily leaves turning yellow?
If it’s after flowering, it’s normal dormancy. During growth it’s often too much water, poor drainage, or too much sun.
Can I grow calla lilies in full sun?
Morning sun and afternoon shade work best. In very cool climates they may handle full sun but watch for stress.
How often should I water my potted calla lilies?
Check soil every couple of days. It should be moist but not soggy. Let the top inch dry slightly between waterings.
Do calla lilies need fertilizer?
Yes, a balanced fertilizer during growth and a bloom booster once buds form.
Will calla lilies bloom all year?
No. They have a natural bloom cycle followed by dormancy. With care you can extend the bloom period but they still need rest.
Keeping Blooms Stunning
To keep blooms looking fresh, avoid splashing water on the flowers, remove faded blooms quickly, and keep plants out of harsh wind. If you’re cutting flowers for arrangements, do it early in the morning when stems are fully hydrated. Calla lilies in a vase can last up to two weeks if you change water regularly.
Final Thoughts from the Field
Calla lilies have taught me patience and observation. They’re not difficult plants, but they do have preferences—just like people. Once you understand their rhythms, they’ll reward you with flowers that can rival anything from a florist. Whether you’re tending a single pot on a balcony or a bed of dozens on a farm like mine, the joy of seeing those elegant blooms open never gets old.
I hope these tips on how to grow, care for calla lily and maintain stunning blooms give you the confidence to try or to tweak what you’re already doing. Which color of calla lily would you love to see blooming in your garden this season?
