Quick Answer
Spider Plant needs bright indirect light and watering once the top inch of soil dries out; brown tips are commonly caused by fluoride and chlorine in tap water rather than watering habits. Switching to filtered or distilled water often resolves the issue. It's a fast-growing, nearly indestructible plant that readily produces plantlets (pups) for easy propagation.
Key Takeaways
- Switch to filtered or distilled water to reduce brown leaf tip formation.
- Water once the top inch of soil has dried out.
- Provide bright indirect light for the fullest, most vigorous growth.
- Root plantlets (pups) easily in water or soil to propagate new plants.
- Keep hanging baskets out of reach if cats show interest in chewing leaves.
The Big Comeback
The Spider Plant (Chlorophytum comosum) was a staple of 1970s interior design, and in 2026, it is experiencing a massive resurgence in popularity. Plant lovers are returning to this classic "bread and butter" plant because it is practically indestructible, incredibly fast-growing, and completely non-toxic to pets.
A Warning for Cat Owners
While Spider Plants are listed as non-toxic (ASPCA listed) by the ASPCA, they are known to have a mild, harmless hallucinogenic effect on felines (similar to catnip). If you have cats, you will likely find them obsessively chewing the long, grassy leaves. To preserve the aesthetic of your plant, it is best kept in a hanging basket out of feline reach.
