Care Guide for Asparagus Fern 'Plumosa'

Light

Prefers bright, indirect light but can tolerate some shade.

Avoid direct sunlight, which can scorch the delicate leaves.

Watering

Keep the soil evenly moist, but not soggy.

Water when the top inch of soil feels dry.

Likes high humidity, so occasional misting is beneficial.

Soil

Well-draining, rich potting mix.

A blend of peat, perlite, and compost works well.
