Why Grow Lilies Indoors?

Lilies are renowned for their dramatic, trumpet-shaped blooms and captivating scents. While many varieties are perfectly suited for outdoor gardens, growing them indoors offers a unique set of advantages:

Year-Round Beauty: Enjoy their blooms even during colder months when outdoor gardening is at a standstill.
Controlled Environment: Protect your delicate lilies from harsh weather, pests, and diseases that can be prevalent outdoors.
Focal Point: Indoor lilies can become a stunning centerpiece, adding color and fragrance to living rooms, entryways, or even kitchens.
Accessibility: Perfect for apartment dwellers or those with limited outdoor space, bringing the joy of gardening inside.
Variety Selection: You can easily find and grow more tender lily varieties indoors that might not overwinter well in your climate.

Choosing the Right Lily for Indoor Growing

Not all lilies are created equal when it comes to indoor living. Some are much more forgiving and better suited to the conditions inside our homes. Look for lilies that are commonly sold as potted plants for indoor enjoyment.

Popular Indoor Lily Varieties:

Asiatic Lilies: These are generally hardier and less fragrant, making them a great choice for indoor environments where strong scents might be overwhelming. They come in a wide array of vibrant colors.
Oriental Lilies: Known for their strong, sweet fragrance and large, showy flowers in shades of pink, white, and red. They require a bit more attention to light and temperature but are well worth the effort.
Easter Lilies (Lilium longiflorum): The classic white lily often associated with spring. They are typically grown as annuals indoors and are relatively easy to care for, providing elegant white blooms.
‘Stargazer’ Lilies: A popular hybrid Oriental lily known for its deep pink/red petals with white edges and a heavenly scent.
Trumpet Lilies: Bearing large, fragrant, trumpet-shaped flowers in colors like white, yellow, pink, and orange.

When purchasing, look for plants with healthy green leaves and buds that are just starting to show color. Avoid plants with yellowing leaves, brown spots, or those that are already fully bloomed and fading.

Essential Indoor Lily Care: A Step-by-Step Guide

Caring for lilies indoors involves understanding their basic needs for light, water, soil, and temperature. Here’s how to provide the best environment for your indoor lilies to flourish.

1. Light Requirements

Lilies love light, but direct, scorching sun can be too much for them indoors. They need bright, indirect light to thrive and produce beautiful blooms.

Ideal Placement: Position your potted lily in an East-facing window, which provides gentle morning sun, or a South-facing window but shielded by a sheer curtain to diffuse the harsh midday rays.
Signs of Insufficient Light: Stems may become leggy and weak, with fewer flowers or smaller blooms. Leaves might turn pale.
Signs of Too Much Direct Sun: Leaves can scorch, appearing burned or crispy. Flowers might fade prematurely.
Rotating Your Plant: Turn the pot a quarter-turn every few days to ensure all sides of the plant receive adequate light and grow evenly.

2. Watering Needs

Proper watering is crucial. Lilies prefer consistently moist soil, but they absolutely cannot tolerate sitting in water, which can lead to root rot.

Check the Soil: Stick your finger about an inch into the soil. If it feels dry, it’s time to water. If it feels moist, wait a bit longer.
Water Thoroughly: When you water, do so until water drains from the bottom of the pot. This ensures the entire root ball is hydrated.
Empty the Saucer: After about 30 minutes, discard any excess water that has collected in the saucer beneath the pot.
Water Quality: If your tap water is heavily chlorinated, let it sit out for 24 hours before watering to allow some of the chlorine to dissipate.
Frequency: Watering frequency will vary depending on the season, room temperature, and humidity. In warmer months, you may need to water more often than in cooler months.

3. Soil and Potting

The right soil mix is key to preventing waterlogged roots and providing nutrients.

Potting Mix: Use a high-quality, well-draining potting mix. A good commercial potting soil formulated for houseplants or flowering plants is ideal. You can amend it with perlite or coarse sand for extra drainage if needed. Experienced gardeners often recommend a mix containing peat moss, perlite, and compost for good aeration and moisture retention. Refer to resources like the Penn State Extension’s guide on container gardening for excellent general principles.
Drainage Holes: Ensure your pot has adequate drainage holes. If you’re using a decorative pot without holes, you can place a smaller pot with drainage holes inside it, or carefully drill holes yourself if using a suitable material like plastic or terracotta.
Pot Size: Choose a pot that is at least 6-8 inches in diameter and depth for a single lily bulb. Lilies don’t like overly large pots, as too much excess soil can retain too much moisture. They prefer to be slightly snug.

4. Temperature and Humidity

Lilies are generally adaptable, but maintaining moderate temperatures will help them perform best indoors.

Ideal Temperature Range: Lilies prefer daytime temperatures between 65-75°F (18-24°C) and slightly cooler nights, around 55-65°F (13-18°C).
Avoid Extremes: Keep them away from direct drafts from heating or air conditioning vents, and away from radiators or fireplaces that can dry them out and cause stress.
Humidity: Lilies appreciate moderate to high humidity. If your home is very dry, especially in winter with heating systems running, consider increasing humidity.
How to Increase Humidity:
- Place the pot on a pebble tray filled with water (ensure the bottom of the pot isn’t submerged).
- Mist the leaves lightly with a spray bottle occasionally, but avoid doing this in direct sunlight as it can cause leaf scorch.
- Use a small room humidifier nearby.

5. Feeding Your Lilies (Fertilizing)

To support lush growth and abundant blooms, your indoor lilies will benefit from regular feeding during their active growing season.

When to Fertilize: Start feeding about 2-4 weeks after the first shoots emerge from the soil, and continue every 2-4 weeks until the blooms fade.
Type of Fertilizer: Use a balanced liquid fertilizer (e.g., 10-10-10 or 20-20-20) diluted to half strength. You can also use a fertilizer formulated for flowering plants.
How to Apply: Water the plant thoroughly before fertilizing to avoid burning the roots. Apply the diluted fertilizer solution according to the product’s instructions.
During Dormancy: Do not fertilize lilies when they are dormant (after blooming and the foliage has died back).

6. Pruning and Deadheading

Keeping your lily plant tidy encourages it to produce more flowers and directs its energy effectively.

Deadheading: Once a flower starts to fade and wilt, gently pinch or cut off the spent bloom just above the flower stem. This prevents the plant from expending energy on seed production and can encourage reblooming or stronger growth for the next season.
Removing Seed Pods: Lilies can develop seed pods after flowering, which also takes energy away from the bulb. Remove these as well once the petals fall.
Foliage Removal: Allow the green foliage to remain on the plant as long as it is healthy and green. The leaves photosynthesize, providing energy for the bulb for future growth and blooms. Only cut back the foliage once it has yellowed and died back naturally, usually after several weeks or months depending on the variety and conditions.

7. Pest and Disease Management

Indoor lilies are generally less prone to pests and diseases than outdoor plants, but it’s still important to be vigilant.

Common Pests: Keep an eye out for aphids (tiny green or black insects, often on new growth or buds) and spider mites (tiny arachnids that create fine webbing, especially in dry conditions).
Inspection: Regularly inspect the leaves (top and bottom), stems, and buds for any signs of infestation.
Treatment Methods:
- Aphids: A strong spray of water can often dislodge them. If persistent, use insecticidal soap or neem oil according to product directions.
- Spider Mites: Increase humidity, thoroughly wet the plant daily, and use insecticidal soap or neem oil.
Preventing Diseases: Good air circulation, proper watering (avoiding soggy soil), and prompt removal of dead foliage are the best ways to prevent fungal diseases.

Understanding Lily Dormancy

Most lilies grown indoors will eventually go through a dormant period. This is a natural part of their life cycle and essential for their long-term health and future blooming.

What is Dormancy?

After the blooming period is over and the foliage begins to yellow and die back, the lily bulb enters a rest period underground. This allows it to store energy for the next growing season.

How to Handle Dormancy:

Stop Watering: Once the foliage has completely yellowed and died back, reduce watering significantly. Allow the soil to dry out a bit more between waterings, but don’t let it become bone dry for extended periods.
Cut Back Foliage: Trim away all the dead, brown foliage, cutting it back to about an inch above the bulb.
Provide Cool Conditions: Move the pot to a cooler location in your home, such as a cool basement, unheated garage, or even a spare room where temperatures are consistently between 40-50°F (4-10°C). This cool period is crucial for encouraging reblooming.
Duration: This dormant period typically lasts for 6-8 weeks.
Reawakening: After the dormancy period, bring the pot back to a lighter, warmer location. Gradually increase watering as you see new shoots emerge. You can also repot the lily into fresh soil at this stage if desired.

If your lily doesn’t go dormant on its own, or if you’re growing a variety that behaves differently, you can gently encourage dormancy by withholding water and reducing light for a few weeks after blooming has finished.

Repotting Your Indoor Lilies

Lilies benefit from occasional repotting to refresh their soil and provide more space for their bulbs to grow.

When to Repot:

Every 1-2 years.
When the plant becomes root-bound (roots are circling the pot or coming out of drainage holes).
When the soil seems depleted or doesn’t retain moisture properly.
Ideally, repot after the dormancy period, just as new growth begins.

How to Repot:

Choose a New Pot: Select a pot that is 1-2 inches larger in diameter than the current one. Ensure it has drainage holes.
Prepare the Soil: Use a fresh batch of well-draining potting mix, as described earlier.
Gently Remove the Lily: Tip the old pot on its side and gently slide the lily and its root ball out. If it’s stuck, carefully run a knife around the inside edge of the pot.
Inspect the Bulb(s): Gently loosen any circling roots. Remove any soft or rotted bulbs. You may find new bulblets attached to the main bulb; these can be separated or left attached.
Plant in the New Pot: Add a layer of fresh potting mix to the bottom of the new pot. Place the lily bulb(s) on top, ensuring the top of the bulb is about 4-6 inches below the soil surface (depending on bulb size). Fill in around the bulb(s) with fresh potting mix, firming gently.
Water and Place: Water thoroughly until water drains from the bottom. Place the newly repotted lily in its usual bright, indirect light location.

Troubleshooting Common Indoor Lily Issues

Even with the best care, you might encounter a few hiccups. Here’s how to address them:

Problem	Possible Cause	Solution
Yellowing Leaves	Overwatering or Underwatering; Lack of light; Nutrient deficiency; Natural aging of lower leaves.	Check soil moisture and adjust watering. Ensure adequate bright, indirect light. Fertilize during the growing season. Remove only fully yellowed leaves.
Drooping or Wilting Flowers	Too hot; Too dry; End of bloom cycle.	Move away from heat sources. Ensure consistent watering. Remove spent blooms to encourage new buds if applicable.
No Blooms	Insufficient light; Not enough dormancy period; Bulb is too small or exhausted; Incorrect fertilization.	Provide at least 6 hours of bright, indirect light. Ensure a proper dormancy period. Repot and possibly divide in spring. Fertilize appropriately during the growing season.
Leggy Stems	Insufficient light; Too much heat.	Move to a brighter location. Ensure temperatures are moderate. Rotate the pot for even growth.
Brown Leaf Tips/Edges	Low humidity; Over-fertilization; Sunburn; Water quality.	Increase humidity. Flush the soil with plain water to remove excess salts from fertilizer. Move away from direct sun. Use filtered or aged water.

Frequently Asked Questions About Indoor Lily Care

Q1: Do I need to keep my lily in the dark after it blooms?

A1: No, generally you should not keep lilies in the dark. After blooming, allow the foliage to remain and continue to photosynthesize as long as it’s green. This energy is stored in the bulb for future growth. Only when the foliage naturally yellows and dies back should you reduce watering and consider providing cooler conditions for dormancy.

Q2: Can I reuse the lily bulb after it blooms indoors?

A2: Yes, absolutely! Most lilies can be kept as perennials. After flowering, allow the foliage to die back naturally, provide a dormancy period, and then repot in fresh soil. With proper care, they can bloom again in subsequent years.

Q3: Why are my lily buds turning brown and falling off?

A3: This can be caused by a few factors, including sudden temperature fluctuations, low humidity, inconsistent watering, or even drafts. Ensure your lily is in a stable environment with consistent moisture and moderate temperatures.

Q4: How long do indoor lilies typically bloom?

A4: The blooming period for indoor lilies varies by variety, but typically lasts for about 2-4 weeks per flower. Multiple buds often develop on a single stem, extending the overall display for a single plant.

Q5: Can I plant lilies in the same pot with other plants?

A5: While it’s possible, it’s generally best to give lilies their own pot. They have specific watering and dormancy needs that can be difficult to manage when planted alongside other species with different requirements. This also makes it easier to manage their dormancy period.

Q6: Should I remove the pollen on lily flowers?

A6: Yes, you can. The pollen anthers on lilies can stain fabrics and furniture. You can gently pull them off once the flower opens, or carefully snip them off to enjoy the blooms without the mess. This doesn’t harm the
