Sprengeri Fern Plant Care
Size & Growth
This plant has arching stems or fronds, which are completely covered with tiny, needle-like leaves known as cladophylls.
The cladophylls have scale-like leaves growing linearly and flat on the plant’s stems to create thorns.
The true leaves are usually bright green or yellowish-green as is the foliage color.
The Asparagus Fern grows about 1’ to 2’ feet tall and 3’ to 4’ feet wide.
Flowering and Fragrance
The mature plants produce pale pink flowers or white flowers during the summer season.
These flowers are sometimes followed by green berries, which gradually transform into bright red berries during the winter.
Avoid consuming these berries as they are poisonous.
Light & Temperature
This plant requires at least six hours of full sun, four to five hours of part sun, and about four hours of partial shade.
It is best to place your indoor plants in a greenhouse or a shady porch during the summer for rapid growth.
The USDA hardiness zone of this plant is 7 to 10.
It tolerates a minimum temperature of 50° degrees Fahrenheit (10° C).
Watering and Feeding

Grooming and Maintenance
The Sprengeri Fern is not a fussy plant and grows optimally with minimal maintenance.
During the spring season, prune back the old stems to allow new growth and to give the plant a neat appearance.
Go about repotting the plant in spring by transferring it to a container which is only one size larger than the previous one.
Make sure to leave around 1” to 2” inches of space between the potting mix and the pot’s rim since the tuberous roots of this plant tend to force the soil up as they grow.
