Start the season right
Plant autumn fern in part sun with at least 4 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Pull a soil test from your local Extension lab to confirm pH and drainage match autumn fern's needs before planting.
Water steadily
Keep the root zone evenly moist through establishment. Match watering to the plant's drainage preference and your local rainfall.
Harvest at its peak
Cut autumn fern blooms in the cool of the morning, just as they open, for the longest display.
