People love calla lilies for their beautiful, trumpet-shaped flowers that come in bright colors like white, pink, yellow, and purple. If you take good care of them, they will give you lots of flowers. But sometimes calla lily plants don’t bloom when you want them to, which can be frustrating and disappointing for any gardener.
Don’t worry! This detailed guide will show you the most common reasons why your calla lilies aren’t flowering and how to get them to start flowering again.
Why Your Calla Lily Has No Flowers
There are several key factors that can prevent calla lily plants from producing flowers:
Inadequate Sunlight
Calla lilies require full sun to partial shade to bloom well At least 4-6 hours of direct sunlight is optimal Too much shade will hinder flowering.
Improper Planting Depth
If you plant bulbs less than 4 inches deep, they probably won’t flower. Plant bulbs at a depth of 2 times their height.
Lack of Dormancy Period
Calla lilies in pots need eight weeks of cool, dry dormancy in the winter. Lack of dormancy prevents energy storage needed for buds.
Dense, Poorly Draining Soil
Wet, compacted soil stresses roots and stops flower production. Callas require loose, humus-rich soil with excellent drainage.
Over-fertilization With Nitrogen
Too much nitrogen fertilizer fuels leaf growth at the expense of flowers. Use a balanced fertilizer like 10-10-10 instead.
Underwatering
Insufficient watering causes calla lily plants to wilt, yellow, and fail to bloom properly. They require consistently moist soil.
Forced Bulbs
Previously forced bulbs often won’t rebloom until they go through a full dormancy period.
Removal of Foliage Too Early
Taking leaves off in fall prevents bulb nutrient storage needed for next year’s flowers.
Fixes to Get Your Calla Lily Blooming Again
If your calla lily has no flowers, try these troubleshooting tips:
-
Move to a sunnier location – Ensure bulbs get at least 4-6 hours of direct sun daily.
-
Check planting depth – Replant any bulbs settled deeper than 4 inches.
-
Provide dormancy – Give potted lilies 8-12 weeks cool & dry dormancy period over winter.
-
Improve drainage – Loosen dense soil, add organic matter to improve drainage.
-
Use balanced fertilizer – Avoid high nitrogen formulas, use 10-10-10 instead.
-
Water thoroughly 1-2 times per week – Keep soil consistently moist but not saturated.
-
Allow forced bulbs to rest – Give forced bulbs a full dormancy period before replanting.
-
Leave foliage until it dies back – Don’t cut leaves until fully brown and shriveled in fall.
Optimizing Care for Maximum Flowers
-
Plant bulbs in humus-rich, well-draining soil. Amend if needed.
-
Site in full sun to partial shade (minimum 4 hours direct sun).
-
Keep soil evenly moist through weekly deep watering.
-
Fertilize monthly with balanced 10-10-10 or tomato feed.
-
Allow foliage to die back fully before removing in fall.
-
Give bulbs 8-12 weeks cool, dry dormancy period before replanting.
Troubleshooting Questions
How long until calla lilies bloom?
Callas typically bloom 12-16 weeks after planting bulbs or rhizomes when given proper care.
Do calla lilies bloom more than once?
Yes, with good care calla lilies will bloom repeatedly through the season and rebloom annually.
Why are my calla leaves turning yellow?
Yellowing leaves often indicate overwatering. Allow soil to partly dry between waterings. Improve drainage if soil is wet.
When should I cut back calla lily leaves?
Never cut foliage until it completely browns and dies back in fall so bulbs can fully store energy.
How can I get my calla lily to bloom again?
Give bulbs a proper dormancy period. Ensure adequate sunlight. Keep soil evenly moist and use balanced fertilizer.
