Boston Fern (보스턴고사리) is one of the most popular houseplants — straightforward once you know its preferences and well suited to indoor life. Here's a quick, no-nonsense care guide: light, watering rhythm, humidity, and whether it's safe around pets.
✅ Pet-safe (cats & dogs)
Good news — Boston Fern is classified non-toxic to cats and dogs by the ASPCA, so it's a solid pick for homes with curious pets. Nibbling any plant can still cause mild stomach upset, so it's best not to encourage it.
Boston Fern care at a glance
☀️ Light
Bright, indirect light is ideal — near an east window or set back from a brighter one. Keep it out of harsh midday sun, which can scorch the leaves.
💧 Watering
As a rule of thumb, water about every 5 days — but always let the top 2–3 cm (1 inch) of soil dry out first. Use the calculator below to fine-tune for your light, season, pot size and humidity. Remember: overwatering, not underwatering, is the most common way houseplants die.
💨 Humidity
Loves higher humidity (50%+). Group it with other plants, sit it on a pebble tray, or run a small humidifier, and keep it away from heating vents.
🌱 Difficulty
Moderately easy — it has a preference or two (usually light or humidity) to get right, but nothing tricky.
