Care Essentials
Get to Know Your Silver Sword Philodendron
Watch the humidity — a little extra moisture in the air goes a long way with this plant.
Light
medium to bright indirect
Most comfortable in medium to bright indirect light. Avoid prolonged direct sun exposure.
💡 Grow lights: Thrives under artificial grow lights (LED or fluorescent, 10-12 hours/day). A great option if your space lacks natural light.
Watering
every 7-10 days
Water when the top 1-2 inches of soil feel dry. Adjust with the seasons — less in winter, more in summer.
Humidity & Temperature
Appreciates some humidity but adapts to average home conditions. Brown tips in winter? Your air might be too dry — a light misting helps.
Standard room temperature (60-80°F / 15-27°C) is perfect. Avoid cold drafts and sudden temperature swings.
Soil
Standard well-draining potting mix works well. Add perlite for extra drainage if you tend to overwater.

Why are my Silver Sword Philodendron leaves turning yellow?
Yellowing foliage on a silver sword philodendron (Philodendron hastatum) is a symptom of the same cultural stresses that affect most vining philodendrons in the home, namely heat that is too high, humidity that is too low, soil that is being kept too dry or too wet, or a combination of those issues; prolonged dryness around the root ball in particular will trigger chlorosis on the arrow-shaped leaves this species is grown for

Why are my Silver Sword Philodendron leaves turning yellow?
Yellowing foliage on a silver sword philodendron (Philodendron hastatum) is a symptom of the same cultural stresses that affect most vining philodendrons in the home, namely heat that is too high, humidity that is too low, soil that is being kept too dry or too wet, or a combination of those issues; prolonged dryness around the root ball in particular will trigger chlorosis on the arrow-shaped leaves this species is grown for
Cause
Yellowing foliage on a silver sword philodendron (Philodendron hastatum) is a symptom of the same cultural stresses that affect most vining philodendrons in the home, namely heat that is too high, humidity that is too low, soil that is being kept too dry or too wet, or a combination of those issues; prolonged dryness around the root ball in particular will trigger chlorosis on the arrow-shaped leaves this species is grown for.
Solutions
- Move the plant to a spot with average home humidity and away from heat registers or drafts, then keep the potting mix evenly moist (moist to the touch) by watering roughly twice a week in spring, summer, and fall, dropping to once a week in winter for pots up to twelve inches.
- If leaves are still yellowing after watering has been corrected, repot into fresh, porous, well-draining soil so the root zone is not staying soggy, and mist the foliage weekly with tepid water to lift humidity around the leaves.
Prevention
Grow the silver sword philodendron at average home temperatures with a ten-degree drop at night, keep the mix evenly moist rather than bone dry or waterlogged, and maintain good air circulation without exposing the plant to cold drafts so yellowing is less likely to set in.

Why does my Silver Sword Philodendron have spider mites?
Red spider mites are a classic pest of vining philodendrons such as P
Cause
Red spider mites are a classic pest of vining philodendrons such as P. hastatum, especially when the indoor air is hot and dry; the mites feed on the leaf surface and leave fine webs at the leaf and stem axils, mottled foliage that turns gray, brown, or eventually crumbles, and they are one of the named causes of brown, dying lower leaves on philodendrons kept in average home humidity.
Solutions
- Spray the whole plant above and below the leaves with a vigorous jet of clear water to break the webs and dislodge the mites, repeating weekly as part of routine foliage care so eggs do not build back up.
- If webs and mottling persist, treat with a miticide such as dicofol (Kelthane) or aramite, sprayed on the whole plant including the undersides of the arrow-shaped P. hastatum leaves.
Prevention
Mist or wipe the foliage at least once a week with clear, tepid water to discourage mites from settling, keep average humidity around the plant, and inspect new plants for fine webbing before placing them next to the silver sword philodendron.
