Everything it needs
9 essentials at a glance
Watering
Tiger Lilies prefer consistently moist soil, especially during their growing season.
Water them deeply once a week, allowing the top inch of soil to dry out between waterings. In hotter months, you may need to increase watering frequency. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and browning leaf tips.
Light
Tiger Lilies thrive in full sun to partial shade.
Ideally, they should receive at least 6 hours of direct sunlight daily. While they can tolerate some shade, too much can hinder blooming. A location with morning sun and afternoon shade is beneficial in hotter climates.
Soil
These lilies prefer well-draining soil with a pH range of 6.0 to 7.0.
A mix of loamy soil and organic matter, such as compost, is ideal. Ensure the soil drains well to prevent waterlogging, which can lead to bulb rot. A recommended potting mix would be a combination of potting soil, peat moss, and perlite.
Humidity
Tiger Lilies prefer moderate humidity levels, around 40-60%.
To increase humidity, you can mist the plants or place a humidity tray filled with water and pebbles beneath the pot. Signs of humidity stress include browning leaf edges and stunted growth.
Temperature
The ideal temperature range for Tiger Lilies is between 60-75°F (15-24°C).
They are hardy in USDA zones 3-9, tolerating cold winters but may struggle in extreme heat. During summer, ensure they have adequate moisture to withstand higher temperatures.
Fertilizing
Use a balanced fertilizer with an NPK ratio of 10-10-10 or 5-10-10.
Fertilize every 4-6 weeks during the growing season, starting in early spring. Signs of nutrient deficiency include yellowing leaves and poor flowering, indicating the need for additional nutrients.
Pruning
Prune Tiger Lilies after they have finished blooming, typically in late summer.
Remove spent flowers and any dead or yellowing leaves to promote healthy growth. Use clean, sharp pruning shears to avoid damaging the plant.
Repotting
Repot Tiger Lilies every 2-3 years or when they become root-bound.
Signs that repotting is needed include roots growing out of the drainage holes or stunted growth. Choose a pot that is 1-2 inches larger in diameter, and carefully transplant them into fresh potting mix, ensuring the bulbs are planted at the same depth.
Propagation
Tiger Lilies can be propagated through bulb division or seeds.
For bulb division, wait until the foliage dies back in late summer, then carefully dig up the bulbs, separate them, and replant them 6-8 inches apart. For seed propagation, collect seeds in late summer, sow them in a seed tray, and keep them moist until germination, which may take several weeks.
When it's unhappy
Yellow leaves
Why it happens
This can be caused by over-watering or nutrient deficiency.
How to fix it
Check the soil moisture and adjust watering accordingly. Fertilize if nutrient deficiency is suspected.
Root rot
Why it happens
Root rot is often caused by excessive moisture and poor drainage.
How to fix it
Ensure the soil drains well and reduce watering frequency. If root rot is severe, remove affected bulbs and replant healthy ones in fresh soil.
Pests (aphids, spider mites)
Why it happens
Pests can infest the plant due to environmental stress or lack of care.
How to fix it
Regularly inspect the plants and treat infestations with insecticidal soap or neem oil.
Poor blooming
Why it happens
Insufficient sunlight or nutrient deficiency can lead to fewer blooms.
How to fix it
Ensure the plant receives adequate sunlight and fertilize regularly to promote blooming.
Browning leaf tips
Why it happens
This may indicate low humidity or under-watering.
How to fix it
Increase humidity around the plant and ensure consistent watering to keep the soil moist.
Care through the year
Spring
In spring, begin fertilizing and ensure the soil is moist as new growth appears. Monitor for pests and provide adequate sunlight.
Summer
During summer, maintain consistent watering and deadhead spent blooms to encourage further flowering. Watch for signs of heat stress.
Fall
In fall, allow the foliage to die back naturally, and reduce watering as the plant enters dormancy. Prepare for winter by mulching around the base.
Winter
In winter, protect the bulbs from extreme cold by mulching. Avoid over-watering during dormancy, and keep the soil slightly moist.
Toxicity & Safety
Tiger Lilies are toxic to cats, with all parts of the plant being harmful. Symptoms of ingestion include vomiting, lethargy, and loss of appetite. They are generally non-toxic to dogs and children, but caution is advised.
