Calla lilies typically take about 12 to 16 weeks to grow from bulbs to blooming flowers.
The exact time to grow calla lilies depends on factors like climate, soil quality, and care practices.
If you’re wondering how long does it take to grow calla lilies, knowing these details will help you enjoy their elegant blooms sooner.
In this post, we’ll explore how long it takes to grow calla lilies, what influences their growth period, and tips to ensure your calla lilies flourish beautifully.
Let’s jump right into understanding the growth timeline of calla lilies.
Why It Takes 12 to 16 Weeks to Grow Calla Lilies
Growing calla lilies to full bloom generally requires 12 to 16 weeks from planting the bulbs.
Here’s why this timeframe is typical and what happens during the growth process:
1. Calla Lilies Grow From Rhizomes
Calla lilies don’t grow from seeds most commonly but from rhizomes, which are bulb-like underground stems.
These rhizomes need time to develop roots, sprout leaves, and eventually grow flower stalks.
The first 4 to 6 weeks are usually spent establishing a strong root system before visible growth above soil appears.
2. Warm Temperatures Encourage Growth
Calla lilies prefer warm conditions with soil temperatures around 60°F to 75°F (15°C to 24°C).
If your growing conditions match this, your calla lilies will progress steadily through their growth stages.
Colder soil or air temperatures slow down their development, making the growing period longer.
3. Photosynthesis and Leaf Development Take Time
Once the lily’s shoots break the soil surface, the leaves begin photosynthesis to feed the plant.
It usually takes several weeks of leaf growth before the flower buds start to form.
This step is crucial for producing energy needed for blooming, which adds to the total growth time.
4. Flower Bud Formation and Blooming Phase
After sufficient leaf development, flower stalks emerge, followed by buds that gradually open.
This blooming stage typically happens between 10 to 14 weeks after planting but can extend to 16 weeks in cooler climates.
Patience is key as the buds slowly develop into the elegant, trumpet-shaped flowers calla lilies are known for.
Factors Affecting How Long It Takes to Grow Calla Lilies
The question “how long does it take to grow calla lilies?” varies depending on several growing factors.
Understanding these will help you optimize your garden for faster and healthier calla lilies.
1. Climate and Season
Calla lilies thrive in warm climates and are typically grown outdoors during spring and summer.
If you plant them too early when the soil is still cold, growth slows drastically.
In warmer zones, calla lilies can start growing almost immediately after planting.
The growing season length in your region is a big factor in how long it takes to grow calla lilies.
2. Soil Quality and Drainage
Calla lilies prefer rich, well-drained soil to thrive.
Poor or soggy soil can stunt growth and increase the time required for lilies to bloom.
Adding compost or organic matter improves soil fertility and drainage, speeding up their growth.
3. Sunlight Exposure
Calla lilies grow best in locations with full to partial sunlight.
Too much shade can slow the rate at which your plants develop leaves and flowers.
Providing the right amount of sunlight encourages faster photosynthesis and healthy blooms.
4. Watering Practices
Overwatering or underwatering can lead to slower growth or rot issues.
Calla lilies prefer consistent moisture but not waterlogged soil.
Balanced watering ensures the rhizomes stay healthy and supports steady growth, affecting how long it takes to grow calla lilies.
5. Fertilization
Using a balanced fertilizer high in phosphorus promotes root and flower development.
Healthy rhizomes and nutrient-rich soil help calla lilies reach blooming faster.
Regular feeding during the growing period can reduce the total time to full growth.
How to Speed Up Growth When Growing Calla Lilies
If you’re eager to know how long does it take to grow calla lilies and want to shorten that time, you can apply some smart gardening tricks.
These tips help your calla lilies grow faster and bloom more reliably.
1. Start Rhizomes Indoors
Begin by planting your calla lily rhizomes indoors in pots about 6 to 8 weeks before your last frost date.
This gives your plants a head start in a controlled environment and reduces the outdoor growing time.
By the time you transplant them outside, the rhizomes are already actively growing.
2. Use Heat Mats or Warm Soil
Calla lilies prefer warmth for root development.
Using a heated mat under the pots or planting in warm soil can significantly accelerate growth.
Maintaining soil temperatures above 60°F encourages quicker sprouting and leaf development.
3. Ensure Proper Drainage and Fertilize Well
Plant your calla lilies in pots or beds with excellent drainage to avoid waterlogged roots slowing growth.
Use a fertilizer with a balanced N-P-K ratio or one slightly higher in phosphorus to promote blooming.
Regular feeding every 4 to 6 weeks during the growing season encourages robust flowers faster.
4. Provide Adequate Light and Water
Place calla lilies in a bright spot where they get morning sun and some afternoon shade.
Keep the soil consistently moist but not soggy.
Ideal watering prevents stress and promotes continuous growth, making sure you see blooms as soon as possible.
5. Remove Spent Blooms Regularly
Deadheading faded flowers directs the plant’s energy toward new growth instead of seed production.
This can help extend the blooming period and encourage additional flower growth during the 12 to 16 week span.
Common Questions about How Long It Takes to Grow Calla Lilies
If you’re still wondering how long does it take to grow calla lilies, these frequently asked questions might help clarify a few points.
1. Can Calla Lilies Bloom Their First Year?
Yes, calla lilies usually bloom in their first growing season if planted at the right time in spring and given proper care.
It generally takes 12 to 16 weeks from planting the rhizome to seeing their signature flowers.
2. How Long Do Calla Lilies Bloom?
Once blooming starts, calla lilies typically flower for about 2 to 3 weeks.
With good care and deadheading, you might enjoy extended blooming periods.
3. Can Calla Lilies Grow Indoors?
Yes, calla lilies can grow indoors in pots, but they still take around 12 to 16 weeks to bloom if conditions like temperature and light are ideal.
Growing indoors gives better control over moisture and warmth, potentially speeding up their growth.
4. What Happens If Calla Lilies Don’t Bloom?
If calla lilies fail to bloom, it’s often due to improper light, insufficient warmth, or not enough nutrients.
Adjusting these factors can shorten the growth time and encourage flowering.
So, How Long Does It Take to Grow Calla Lilies?
In summary, how long does it take to grow calla lilies? The typical answer is 12 to 16 weeks from planting rhizomes to full bloom.
This period depends on factors like temperature, soil, watering, and light.
With proper care, good soil, and warm conditions, your calla lilies will develop beautiful flowers within this timeframe.
Starting rhizomes indoors, maintaining warm soil, and providing proper nutrients can help speed up the process if you’re impatient for those gorgeous blooms.
Remember that patience and consistent care are key when growing calla lilies to reach their elegant flowering stage.
