How to Take Care of an Asparagus Fern


The asparagus fern (Asparagus densiflorus 'Sprengeri') has delicate, lacy foliage that trails outward via long stems and is most commonly grown as a houseplant. This plant is native to South Africa and produces tiny flowers and berries. Reaching 2- to 6-feet tall, the asparagus fern is actually not a fern at all, but instead is related to the asparagus. This houseplant is often planted in hanging baskets and kept in lower light levels. Asparagus ferns require little extra care and enjoy normal indoor environmental conditions.

Step 1

Position your asparagus fern in bright but indirect, filtered sunlight. Don't place the plant in direct, full sun. Maintain normal indoor air temperatures around your asparagus fern of 65 to 75 degrees F.

Step 2

Water your asparagus fern two or three times per week to keep the soil constantly moistened, but don't waterlog the soil. For older asparagus ferns, as a supplement to regular watering, you can submerge the pot in water once every one or two months, because their roots fill the pots more densely, making it more difficult for them to retain moisture. During winter, water your asparagus fern only as needed to keep the soil from drying out completely.

Step 3

Mist your asparagus fern daily or once every two or three days to keep the humidity levels high around the plant.

Step 4

Feed your asparagus fern once every two weeks from February through October with an all-purpose liquid houseplant fertilizer. Follow the dosage instructions on the label.

Step 5

Re-pot your asparagus fern when its roots begin to fill the pot. Re-pot the plant in the spring before new growth emerges, using a potting mixture of two parts peat moss, two parts loam and one part sand or perlite.

Tips and Warnings

  • Be careful of where you keep your asparagus fern in your house, because the fern is poisonous to children and pets if eaten.
