Plume Asparagus

bright indirect light (3-6 feet from a south or west window, or right next to an east window. Under a grow light, 6-10 inches away works well) is ideal. Place within 3 feet of a south-facing window or near an east-facing window. Too much direct sun (right in the window where sun actually hits the leaves. A strong grow light 4-6 inches away can substitute) yellows the needles; too little causes pale, limp growth. Tolerates bright artificial light well.

Prefers higher humidity; aim for 40% or above. Dry indoor air causes needle shed. Mist daily, use a pebble tray, or place in a naturally humid room like a kitchen or bathroom.

Well-draining, moderately rich potting mix. The plant develops thick, tuberous roots that store water, so sharp drainage prevents rot. A standard potting mix with added perlite works well.

Needle drop from underwatering, low humidity, or dry air. Yellowing from overwatering or excess direct sun. Mature stems may develop small sharp spines - handle with gloves. Watch for mealybugs, spider mites, and scale.
