How to Grow

Cultivation

Grow under glass, keep moist in full light with shelter from hot sun. Use an acidic potting medium with moss. In winter, keep slightly drier, cool and well ventilated. Irrigate with lime-free water. They will generally lose some of their leaves over winter during a period of dormancy. Most Sarracenias can be grown outside in milder parts of the country, but care should be taken in colder conditions. Choose a position in full sun, sheltered from cold winds.
