Why Grow Lilies Indoors?

Lilies are more than just beautiful flowers; they bring a touch of elegance and a sweet fragrance to any room. Growing them indoors offers several delightful advantages:

Year-Round Beauty: Unlike their outdoor counterparts, indoor lilies aren’t limited by seasons. Enjoy their blooms whenever you please!
Aromatherapy: Many lily varieties release a lovely scent, naturally perfuming your home and creating a relaxing atmosphere.
Space Savers: Perfect for apartments, small homes, or anyone looking to add floral flair without a large garden.
Bring Nature Inside: Especially during colder months, indoor plants like lilies can lift spirits and connect you with nature.
Vibrant Colors: Lilies come in a spectacular range of colors—from pure white and soft pink to fiery orange and deep red—adding a pop of color to your decor.

Understanding Your Indoor Lily Plant

Before we dive into care, it’s helpful to know that most lilies grown indoors are usually specific varieties or bulbs started for indoor blooming. These aren’t typically perennial plants that will regrow year after year in the same pot like you might see outdoors. Often, they are treated as annuals or carefully nurtured to potentially bloom again. The key is providing the conditions they love, which are a bit different from their natural outdoor habitats.

Common Indoor Lily Types

While less common than outdoor varieties, some lilies are specially cultivated or bulbs are forced for indoor display. The most frequent ones you’ll encounter for indoor enjoyment are:

Easter Lilies (Lilium longiflorum): Famous for their trumpet-shaped white blooms, often seen around springtime holidays. They are among the most popular for indoor forcing.
Asiatic Lilies: Known for their bright, cheerful colors and star-shaped flowers. They tend to be more compact and might tolerate indoor conditions better.
Oriental Lilies: Renowned for their large, often fragrant flowers and vibrant colors. They can be a bit more sensitive to indoor environments.

It’s important to note that many beautiful “lilies” sold for indoor use might actually be other plants that are called lilies but belong to different families, like Calla Lilies (Zantedeschia) or Peace Lilies (Spathiphyllum). For this guide, we’re focusing on true lilies (genus Lilium) and their specific needs. If you have one of the other “lilies,” their care can differ significantly!

Essential Care Steps for Indoor Lilies

Caring for your lily plant indoors is a rewarding experience. It involves paying attention to a few key elements. Let’s break it down into manageable steps:

Step 1: The Right Spot: Light Requirements

Lilies absolutely love light! For them to thrive and bloom beautifully indoors, they need plenty of it. However, “plenty” for a lily doesn’t always mean scorching hot, direct sun all day.

Ideal Placement: Lilies do best in bright, indirect sunlight. Think of a south-facing window where the sun is strong but filtered, or an east-facing window that gets bright morning sun.
Direct Sun Caution: While they need light, intense, direct afternoon sun, especially through a windowpane, can scorch their leaves and dry out the soil too quickly. If your sunniest window is very harsh, you might want to place the lily a little back from the window or use a sheer curtain as a diffuser.
Signs of Insufficient Light: If your lily’s stem becomes long and leggy, with leaves spaced far apart, it’s stretching for light. If it’s not flowering, light is often the culprit.
Signs of Too Much Direct Sun: Brown, crispy edges on leaves or wilting even when the soil is moist can indicate sunburn.

Aim for at least 6 hours of bright light per day. If your home doesn’t have a naturally bright spot, consider using a grow light. This is becoming increasingly popular and effective for indoor gardeners. For example, full-spectrum LED grow lights can mimic natural sunlight and are essential for plants in darker homes. You can find more information on choosing suitable grow lights from resources like the Royal Horticultural Society (RHS), a trusted authority on gardening.

Step 2: The Perfect Potting Mix: Soil Matters

The right soil is crucial for healthy roots. Lilies, like most plants, hate having “wet feet,” meaning their roots sitting in soggy soil. This can lead to root rot, a common and often fatal problem.

Drainage is Key: Use a well-draining potting mix. A good quality commercial potting soil for houseplants is a great start.
Amending the Mix: To improve drainage even further, you can add amendments like perlite or coarse sand to your potting mix. A good ratio might be 3 parts potting soil to 1 part perlite.
Avoid Garden Soil: Never use soil directly from your garden. It’s too dense, compacts easily in pots, and can introduce pests or diseases.
Pot Choice: Ensure your pot has drainage holes at the bottom. Terracotta pots are excellent because they allow the soil to breathe and dry out a little faster, which lilies appreciate. However, plastic pots retain moisture longer, so you’ll need to be more careful with watering if you choose those.

Step 3: Watering Wisely: Not Too Much, Not Too Little

Watering is perhaps the most challenging aspect for many indoor gardeners. Lilies prefer consistent moisture but dislike being waterlogged.

Check Soil Moisture: The best way to know when to water is to feel the soil. Stick your finger about an inch or two 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 runs out of the drainage holes at the bottom of the pot. This ensures the entire root ball gets hydrated.
Discard Excess Water: Never let the pot sit in a saucer full of water. Empty the saucer about 30 minutes after watering.
Watering Frequency: This will vary with light, temperature, and humidity. In warmer, brighter conditions, you’ll water more often than in cooler, less-lit spots. It could be every few days to once a week.
Water Quality: If your tap water is heavily chlorinated or fluoridated, consider letting it sit out overnight before watering. This allows some of the chemicals to dissipate. Filtered water or rainwater is even better.

Step 4: Temperature and Humidity: Creating a Cozy Environment

Lilies like comfortable temperatures and appreciate a bit of humidity. Extreme fluctuations aren’t good for them.

Temperature: Most lilies prefer moderate room temperatures, ideally between 65-75°F (18-24°C) during the day. They can tolerate cooler temperatures at night, around 55-60°F (13-16°C), which can sometimes encourage blooming. Avoid placing them near drafts from heating or air conditioning vents, as this can dry them out or shock the plant.
Humidity: While not as critical as for some tropical plants, lilies appreciate some humidity. Dry indoor air, common in winter, can cause leaf tips to turn brown or flowers to dry out prematurely.
Increasing Humidity:
- Pebble Tray: Place the pot on a tray filled with pebbles and water. As the water evaporates, it increases humidity around the plant without letting its roots sit in water.
- Misting: Lightly misting the leaves occasionally can help raise humidity, but avoid doing this late in the day, as wet foliage can encourage fungal diseases.
- Grouping Plants: Placing your lily with other houseplants can create a slightly more humid microclimate.

Step 5: Feeding Your Lily: Fertilizer Facts

Indoor lilies, especially those being encouraged to re-bloom, benefit from a little boost of nutrients.

When to Fertilize: Fertilize when the plant is actively growing and blooming. Avoid fertilizing a dormant or stressed plant.
Type of Fertilizer: Use a balanced liquid fertilizer (e.g., 10-10-10 or 20-20-20) diluted to half strength. Some gardeners prefer fertilizers formulated for blooming plants, which might have a higher middle number (phosphorus).
Frequency: During the growing and blooming season (spring and summer), fertilize about once every 2-4 weeks. Reduce or stop fertilizing in fall and winter when the plant’s growth naturally slows down.
Application: Always water your lily before fertilizing. Applying fertilizer to dry soil can burn the roots.

Step 6: Post-Bloom Care: What to Do After Flowers Fade

Once the beautiful lilies finish blooming, don’t just toss the plant! With proper care, you might be able to encourage it to bloom again, or at least maintain its greenery.

Deadheading: As flowers fade, gently snip them off at the base of the stem. This prevents the plant from putting energy into seed production and keeps the plant looking tidy.
Continue Watering and Light: Keep watering as usual and ensure it has bright light. The leaves are still photosynthesizing and feeding the bulb for future growth.
Dormancy: Many bulbs, including lilies, go through a dormant period. For indoor lilies, this might mean the leaves start to yellow and die back naturally. If this happens, slowly reduce watering. Once the foliage has completely died back, you can cut the stems at the soil line.
Storing Bulbs (Optional, and Tricky Indoors): Some gardeners choose to dig up the bulbs (if the plant is in a pot large enough to do so discreetly) and store them in a cool, dry, dark place over winter, repotting them in fresh soil come spring. This is more common with outdoor bulbs but can be attempted indoors. However, for ease, many treat indoor forced lilies as annuals or simply maintain them for their foliage.
Encouraging Rebloom: To encourage reblooming, after the plant goes dormant, you can try repotting it in fresh soil and then placing it in a cool, dark place (like a refrigerator, but not with fruits that produce ethylene gas) for about 6-8 weeks. Then, bring it back into warmth and light and resume watering. This mimics the natural cycle.

Common Pests and Problems

Even indoor plants can attract unwanted visitors or encounter issues. Staying vigilant is key to catching problems early.

Problem	Signs	Solution
Aphids	Tiny green, black, or brown insects usually on new growth or undersides of leaves; sticky residue (honeydew).	Wipe off with a damp cloth. Spray with insecticidal soap or neem oil. You can also blast them off with a strong spray of water. Visit EPA’s IPM principles for more eco-friendly pest strategies.
Spider Mites	Very tiny, often red or brown, mites. Look for fine webbing, especially on leaf undersides; speckling or yellowing leaves. They love dry conditions.	Increase humidity (pebble tray, misting). Wash leaves with water. Use insecticidal soap or neem oil.
Fungus Gnats	Small black flies hovering around the soil surface; larvae live in the soil and can damage roots. Often a sign of overwatering.	Let the top inch or two of soil dry out between waterings. Use yellow sticky traps to catch adults. Consider a soil drench with diluted hydrogen peroxide in severe cases.
Yellowing Leaves	Can be due to overwatering, underwatering, or lack of light. Lower leaves yellowing naturally as the plant matures is also common.	Check soil moisture first. Adjust watering. Ensure adequate light. If it’s only lower leaves and the plant otherwise looks healthy, it might just be natural aging.
Brown Leaf Tips	Often caused by low humidity, inconsistent watering, or minerals/salts building up in the soil from tap water or fertilizer.	Increase humidity. Water consistently. Flush the soil occasionally by watering heavily until water runs freely from the bottom, discarding excess. Use filtered or distilled water. Trim off brown tips if desired, but new growth is more important.

Tips for Encouraging Reblooming Indoors

Getting your lily to bloom again indoors can be a rewarding challenge. While some varieties are easier than others, here are some tips to guide you:

Patience is a Virtue: Don’t expect multiple blooms immediately after the first flush. Indoor lilies are often grown for a single blooming event.
Mimic Natural Cycles: To encourage reblooming, you’ll need to replicate the bulb’s natural dormancy period. This typically involves a cool, dark rest.
Post-Bloom Care: After the flowers fade, continue providing good light and water until the foliage starts to yellow and die back naturally. This nourishes the bulb.
The Cool Dormancy: Once the leaves have died back, you can either:
- Option A (Simpler): Cut back the dead foliage. Reduce watering to almost none. Store the pot in a cool, dark place (around 40-50°F or 4-10°C) for 6-8 weeks.
- Option B (More Advanced): Gently unpot the bulb(s). Remove excess soil. Store the bulbs in a breathable bag (like mesh or paper) with slightly damp peat moss or vermiculite in a cool, dark place for 6-8 weeks.
Wake-Up Time: After the dormancy period, repot the bulb(s) in fresh, well-draining potting mix. Place the pot in a bright, indirect light location and resume watering. With warmth and light, new growth should appear.
Fertilizing for Blooms: Once you see new growth and the plant is actively growing, begin fertilizing according to the schedule mentioned earlier to support blooming.
