Will my calla lily come back? Yes, your calla lily can come back with proper care and attention.
If you’re wondering whether that beautiful calla lily you planted will return after dormancy or harsh weather, you’re in the right place.
In this post, we’ll dive into why calla lilies come back, how to care for them to encourage their return, and common things that might keep your calla lily from coming back.
Let’s get started with understanding when and why your calla lily will come back.
Why Your Calla Lily Will Come Back
Your calla lily will come back because it is a perennial plant with a tuber or rhizome that stores energy through dormant periods.
1. Calla Lilies Are Hardy Perennials
Calla lilies are classified as perennial plants, which means they have the natural ability to survive through dormant seasons and regrow year after year.
Their underground rhizomes act like storage batteries that keep the energy the plant needs to sprout new growth when conditions improve.
2. Dormancy Helps Calla Lilies Survive Harsh Conditions
During cold winters or dry seasons, calla lilies naturally enter dormancy, shedding their leaves and slowing down their metabolic processes.
This dormancy phase protects the rhizomes underground, which allows your calla lily to come back stronger the following growing season.
3. Proper Planting Depth Encourages Return
If you planted your calla lily tubers at the right depth—typically 3 to 4 inches deep in well-drained soil—it supports healthy rhizome growth.
This depth shields the rhizome from extreme temperatures and encourages new shoots to push up through the soil, helping your calla lily come back each year.
What You Need to Do to Help Your Calla Lily Come Back
If you want your calla lily to come back, caring for it properly during and after dormancy is crucial.
1. Know When to Remove Dead Foliage
After your calla lily blooms and its leaves start yellowing or dying back, remove the dead foliage carefully.
This cleanup prevents disease and signals to the plant that its growing season has ended, helping it prepare for dormancy and a fresh start next season.
2. Control Watering During Dormancy
Calla lilies need less water during dormancy, so reduce watering once the foliage begins to die back.
Too much water during dormancy can cause the rhizomes to rot and prevent your calla lily from coming back.
Keep soil slightly moist but never soggy until you see new growth.
3. Protect Your Calla Lily from Frost
Since calla lilies are tropical perennials, they can struggle in freezing temperatures.
If you live in an area with frost, it’s best to dig up the rhizomes before the first frost and store them in a cool, dry place.
You can replant these tubers in the spring to ensure your calla lily comes back.
4. Fertilize to Encourage Growth
Applying a balanced, slow-release fertilizer in the growing season will give your calla lily the nutrients it needs to come back robustly.
Special care during the growing season strengthens the rhizome underground and improves flowering when your calla lily returns.
5. Repot or Divide Overcrowded Plants
If your calla lily is potted or has become overcrowded in the garden, dividing the rhizomes every few years encourages fresh growth.
This division allows multiple new plants to come back healthier and promotes more vibrant blooms.
Common Reasons Your Calla Lily Might Not Come Back
If your calla lily doesn’t come back, there are a few common issues that could be the cause.
1. Rhizome Rot Due to Overwatering
The number one reason calla lilies fail to come back is rhizome rot caused by excessive moisture.
Wet soil conditions during dormancy can cause the rhizome to decay and prevent new growth.
Always ensure well-drained soil and reduce watering when your calla lily is dormant.
2. Frost Damage or Cold Climate
Calla lilies are sensitive to frost and cold climates, especially if they’re planted directly in the ground without protection.
If you experience hard freezes, your calla lily might die back completely unless you have taken measures to protect or lift the tubers.
3. Poor Soil Conditions
Calla lilies like rich, well-drained soils that retain moisture but don’t stay waterlogged.
Poor soil conditions can stunt growth or prevent your calla lily from coming back.
Adding compost and ensuring proper soil drainage can solve many growth problems.
4. Planting Depth Too Shallow or Too Deep
If the rhizomes were planted too shallow, they might dry out during winter.
If planted too deep, the new shoots might struggle to reach the surface.
Both cases can prevent your calla lily from returning in the spring.
5. Pests and Diseases
Pests like aphids or diseases like fungal infections can weaken your calla lily and interfere with its ability to come back.
Monitoring your plant for these issues and taking early action can protect your calla lily’s return each year.
Tips for Growing Calla Lilies Year-Round
While your main concern might be whether your calla lily will come back next season, there are tips to help your calla lily thrive year-round.
1. Provide Plenty of Sunlight
Calla lilies thrive in bright, indirect sunlight.
Keeping them well-lit during the growing season strengthens them and encourages vigorous growth so they’re ready to come back year after year.
2. Maintain Consistent Moisture
During the active growing period, calla lilies love consistent moisture but dislike soggy soil.
Water them regularly but allow the soil surface to dry slightly between waterings to avoid root problems.
3. Use Mulch to Protect Soil
Applying mulch around your calla lilies can regulate soil temperatures and moisture levels.
Mulch also protects the soil from frost in cooler climates and can help ensure your calla lily comes back healthy.
4. Know When to Lift Tubers
In colder regions, it’s important to dig up the rhizomes after the foliage has died back in fall.
Store tubers in a dark, dry spot for winter, then replant when the danger of frost has passed so your calla lily will come back reliably.
5. Propagate to Multiply Your Plants
Dividing rhizomes every few years not only helps your calla lily come back but allows you to propagate new plants to share or expand your garden.
So, Will My Calla Lily Come Back?
Your calla lily will come back as it is a hardy perennial that uses its tuber to survive dormant periods.
With proper care such as managing watering, protecting from frost, planting at the right depth, and giving it the right nutrients, your calla lily can return year after year with beautiful blooms.
Avoiding common pitfalls like overwatering and poor soil will also help ensure your calla lily comes back strong.
If you follow the care tips above, your calla lily should be a delightful, long-lasting addition to your garden.
Happy gardening!
