How to care for Asparagus Fern
Asparagus setaceus

How often should I water Asparagus Fern, and what light does it need?
Asparagus ferns are fluffy, forgiving, and easy — water when the top inch dries. Despite the name it's not a true fern, so it tolerates brighter light and drier air. Water it every 5–7 days while it is growing and every 8–12 days in winter, always checking the soil first. Give it medium light. It is toxic to cats and/or dogs — more detail below.

The short version
The one-sentence rule
Water when the top inch dries. It's not a true fern — it wants slightly drier, brighter conditions than a boston fern.
Light, made concrete
What medium light actually means
Medium light — a meter or two from a north or east window, bright but no harsh sun. The sweet spot for most common houseplants.
Pet safety
Is Asparagus Fern toxic to cats or dogs?
Yes — Berries and foliage can cause an upset stomach and skin irritation. If your pet chews the plant, expect possible mouth irritation or an upset stomach, and call your vet if symptoms are more than mild. Keep it out of reach where you can.
