Care Essentials
Get to Know Your Hosta
A resilient houseplant. With basic care, Hosta 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.

Hosta: Crown Rot
Fungal pathogen Sclerotium rolfsii, which appears as white thread-like growth (mycelium) and tiny mustard-seed-like structures (sclerotia) at the base of the plant during hot, humid weather
Cause
Fungal pathogen Sclerotium rolfsii, which appears as white thread-like growth (mycelium) and tiny mustard-seed-like structures (sclerotia) at the base of the plant during hot, humid weather.
Solutions
- Remove the infected hosta and a generous amount of surrounding soil (where sclerotia can live for years).
- Do not replant hostas in the same spot unless the soil is sterilized or replaced.
- Use fungicides containing flutolanil or PCNB if the infection is caught early.
Prevention
Avoid heavy organic mulches that touch the petioles of the hosta, as this creates the moist environment the fungus requires to attack the crown.
