Why You Can Get Calla Lily to Rebloom
If you’re wondering how to get calla lily to rebloom, the good news is that calla lilies are perennial plants that naturally have the potential to flower repeatedly with the right care.
Here’s why you can get calla lily to rebloom:
1. Calla Lilies Have a Dormant Growth Cycle
Calla lilies go through distinct growth, blooming, and dormant phases every year, so they are designed to rebloom after resting.
Their bulbs or rhizomes store energy during dormancy that feeds new blooms during the growing season.
Understanding this natural cycle is key to knowing how to get calla lily to rebloom.
2. Calla Lilies Respond to Proper Care After Dormancy
Getting calla lily to rebloom depends on helping them transition out of dormancy with appropriate watering, feeding, and temperature conditions.
Once the plant’s rest period is over, it needs good care to trigger new shoots and flower spikes.
3. Healthy Bulbs Are Vital for Rebloom
The calla lily’s ability to rebloom depends significantly on the health of its bulbs or rhizomes.
Strong, disease-free bulbs will have the energy reserves needed to produce flowers again.
So, ensuring your bulbs remain healthy is crucial for rebloom success.
Best Practices for How to Get Calla Lily to Rebloom
Knowing how to get calla lily to rebloom involves a mix of proper watering, fertilization, light management, and giving them a rest period.
Here’s a breakdown of the best strategies for getting your calla lily to bloom again:
1. Provide Plenty of Bright, Indirect Light
Calla lilies love bright light, but direct harsh sunlight can sometimes burn the leaves.
For how to get calla lily to rebloom, placing your lilies near a bright window or in filtered light outdoors gives them the energy they need for flower production.
Without adequate light, your calla lily may grow foliage but fail to flower again.
2. Maintain Consistent Moisture Without Overwatering
During the growing season, keeping the soil moist but not soggy is key to encouraging calla lilies to rebloom.
Too much water can cause bulb rot, while insufficient water stresses the plant.
For how to get calla lily to rebloom, aim to water whenever the top inch of soil feels dry to the touch.
3. Feed with Balanced Fertilizer Regularly
Calla lilies benefit tremendously from a balanced, water-soluble fertilizer applied every few weeks while they are actively growing.
When learning how to get calla lily to rebloom, make sure to feed with a fertilizer that has equal parts nitrogen, phosphorus, and potassium.
Phosphorus in particular helps promote blooming, so look for formulas labeled “bloom booster” if you want your calla lily to flower again.
4. Allow for a Rest Period Each Year
An essential part of how to get calla lily to rebloom is giving the plant a dormancy period each year after flowering.
This means reducing watering and letting the leaves die back naturally so the bulbs can rest.
After a couple of months of rest—usually in late fall or winter—you can begin watering again to signal the bulbs to grow and bloom next season.
5. Repot or Divide the Bulbs If Necessary
If your calla lily isn’t reblooming year after year, it could be because the bulbs have become crowded or depleted.
Repotting the bulbs in fresh soil or dividing large clumps every 2-3 years rejuvenates them and improves their chances of flowering again.
This is a critical step in how to get calla lily to rebloom when your plant looks crowded or stops flowering.
Common Mistakes That Stop Calla Lilies From Reblooming
Sometimes, even with love and care, calla lilies refuse to rebloom.
Here are the most common errors that prevent your calla lily from flowering again and how to avoid them to succeed in how to get calla lily to rebloom:
1. Neglecting the Dormancy Period
Keeping your calla lily watered constantly without allowing for rest can exhaust the bulbs and halt rebloom.
It’s tempting to treat them like houseplants that grow non-stop, but for how to get calla lily to rebloom, a solid dormancy with less water is essential.
2. Insufficient Light
Calla lilies won’t bloom well if they’re not getting enough bright, indirect light.
A shady spot or too much shade indoors can cause them to become leggy and not flower at all.
If your calla lily isn’t blooming, consider moving it to a brighter location.
3. Overfeeding or Underfeeding
Both too much fertilizer and too little can cause problems.
Too much nitrogen fertilizer encourages foliage but discourages flowering.
Conversely, not enough nutrients deprives the plant of what it needs for energy reserves to rebloom.
Use a balanced fertilizer on schedule to get the best results for how to get calla lily to rebloom.
4. Ignoring Pest and Disease Issues
Pests like aphids or fungal diseases affecting the bulbs or foliage can weaken the plant and stop it from reblooming.
Regularly check your calla lily for signs of trouble and treat early with insecticidal soap or fungicide to protect the bulbs and leaves.
5. Crowded or Old Bulbs
If your calla lily’s bulbs are too crowded or are more than a few years old, they may struggle to produce flowers.
Dividing and repotting bulbs is a key part of how to get calla lily to rebloom.
Refreshing your calla lily’s growing environment every couple of years boosts flowering potential.
Extra Tips to Encourage Reblooms in Calla Lilies
Beyond the basics of how to get calla lily to rebloom, here are extra tips that can make a difference for your calla lilies:
1. Use Well-Draining Soil
Calla lilies like soil that holds moisture but also drains well.
Heavy, waterlogged soil can suffocate the bulbs and cause rot, halting rebloom.
Mix potting soil with sand or perlite for good drainage if you’re growing in containers.
2. Avoid Sudden Temperature Changes
Calla lilies prefer stable, warm temperatures during the growing season, ideally between 60-75°F (15-24°C).
Sudden drops in temperature can shock the plant and hinder rebloom.
Keep your calla lily away from cold drafts or hot vents.
3. Support Tall Stalks
As your calla lily starts to rebloom, the flower stalks can sometimes get top-heavy.
Supporting them with stakes or ties can prevent damage and encourage healthier blooms.
4. Practice Patience
Calla lilies sometimes take a full growing season plus dormancy before reblooming.
Don’t be discouraged if your plant doesn’t flower immediately.
Consistent care over the months will pay off in blooms eventually.
So, How to Get Calla Lily to Reblooms Successfully?
How to get calla lily to rebloom boils down to understanding their natural cycle and meeting their needs for light, water, nutrients, and rest.
By providing bright, indirect light, keeping the soil moist but well-drained, feeding with a balanced fertilizer, and allowing your calla lily a proper dormancy period, you give it the best chance to flower year after year.
Avoiding common mistakes like overwatering, ignoring dormancy, and letting bulbs get crowded also plays a big role in your success.
With patience and a little care, you can enjoy the elegant beauty of calla lilies blooming again and again.
