info
Water this plant regularly. The soil surface should feel damp or just barely dry at all times. Usually this will mean once or twice a week in dry weather. Use drippers, emitters, or a slow stream of water so that it doesn’t run off; allow the water to trickle all the way down through to the deepest layers of soil. In a pot slowly water the entire surface until water comes out of the bottom of your pot.

Tree ferns appreciate moisture in their crown, which can be achieved with overhead water or a dripper run up into the crown of the plant.

Growing Notes

Trim off older fronds when they begin to look ratty and later, but allow the stubs to come off on their own with time.
Can be grown in full sun if close to the coast in marine influence zones.
