Care Essentials

Get to Know Your Lilium

A resilient houseplant. With basic care, Lilium is hard to kill.

Light

medium to bright indirect

Most comfortable in medium to bright indirect light. Avoid prolonged direct sun exposure.

💡 Grow lights: Thrives under artificial grow lights (LED or fluorescent, 10-12 hours/day). A great option if your space lacks natural light.

Watering

every 7-10 days

Water when the top 1-2 inches of soil feel dry. Adjust with the seasons — less in winter, more in summer.

Humidity & Temperature

Not fussy about humidity. Handles average indoor conditions without issue.

Standard room temperature (60-80°F / 15-27°C) is perfect. Avoid cold drafts and sudden temperature swings.

Soil

Standard well-draining potting mix works well. Add perlite for extra drainage if you tend to overwater.

⚠️ May be toxic to pets. Keep out of reach of cats, dogs, and small children.
Difficulty moderate

Lilium: Rodent Damage

Hungry rodents including voles, mice, and squirrels are described as the worst problem for garden bulbs and will dig up and eat lily bulbs as a food source throughout the year, treating larger lily bulbs the same way they treat tulip bulbs

80%
Cause

Hungry rodents including voles, mice, and squirrels are described as the worst problem for garden bulbs and will dig up and eat lily bulbs as a food source throughout the year, treating larger lily bulbs the same way they treat tulip bulbs.

Solutions
  • Interplant bulbs with a groundcover to deter rodents from locating the lily bulbs in the bed.
  • Plant larger bulbs like tulips and lilies inside a hardware-cloth cage by digging a 12-inch-deep trench around the bed and lining it with ½-inch wire mesh.
Prevention

Add a handful of fine crushed gravel on top of each bulb at planting time, or mix a slate-particle product into the soil to discourage voles from tunneling toward the lilies.

Lilium: Toxic To Cats

Unidentified nephrotoxin in all plant parts including petals, leaves, stems, pollen, and vase water destroys renal tubules in cats

95%
Cause

Unidentified nephrotoxin in all plant parts including petals, leaves, stems, pollen, and vase water destroys renal tubules in cats

Solutions
  • Immediate emergency veterinary care within 6 hours
  • Aggressive IV fluid therapy
  • Activated charcoal administration
  • Monitoring kidney function and urine output
Prevention

Do not keep any true lilies (Lilium or Hemerocallis) in homes with cats
