Foxtail Fern

Foxtail fern is native to southern Africa and is not a true fern but a member of the asparagus family. It produces dense upright plume like stems that store water in tuberous roots below the soil surface. Because of those storage roots it tolerates short dry periods better than most ferns but still prefers steady moisture and strong light. Stem density color depth and firmness are strong indicators of overall energy and placement.

Water using your soak and dry rhythm checking the root zone with a chopstick or moisture meter before watering. The soil should be well draining and aerated using a quality potting base blended with bark and perlite to prevent compaction and protect the tuberous root system. Water thoroughly then allow the root zone to dry down before watering again. Yellowing stems with soft bases often signal soil staying too wet while thinning plumes and excessive needle drop indicate extended dryness or insufficient light.

Direction of light should be bright and direct tolerant. A south window within one to three feet of the glass works very well. An east window within one to two feet is also suitable though growth may be slightly less dense. North exposure is usually not strong enough to maintain compact plumes. If using a grow light choose five thousand to sixty five hundred Kelvin positioned twelve to eighteen inches above the plant for ten to twelve hours daily. When positioned correctly the plant produces dense upright bright green plumes with strong structure and steady new growth.
