Frequently asked
Who writes indoorplantcare.com?
Thomas Joseph. I write the guides on this site. The ones about plants I have grown are first-person; the ones about plants I have not are sourced entirely from primary horticultural literature. Either way, every claim cites a source.
How do I know your plant toxicity information is accurate?
Every toxicity claim on this site cites the ASPCA Toxic and Non-Toxic Plants database directly. Where ASPCA has no standalone entry, I cite NC State Plant Toolbox or University of Illinois Veterinary Medicine instead. The plant database is verified against primary sources on an ongoing basis.
What is the best indoor plant for beginners?
Pothos and snake plant are the two species I recommend most often for first-time plant owners. Both tolerate low light, both forgive irregular watering, and both propagate easily. The honest tradeoff: both are toxic to cats and dogs per ASPCA, so cat households should consider spider plant or parlor palm instead.
How often should I water my houseplants?
It depends on the plant, pot, light, and season. Use the watering frequency calculator on this site for a personalized starting point. As a rule of thumb: most tropical houseplants want water when the top inch of soil is dry. Succulents and snake plants want the soil bone-dry. Always finger-test before watering on a schedule.

Yes. Gear pages contain Amazon affiliate links. I only recommend products I have personally used or that primary sources back. As an Amazon Associate I earn from qualifying purchases. See the full affiliate disclosure linked in the footer.
