Care guides
Six guides, one per plant type people actually buy in a small pot.
Cactus care Water rarely, light hard, don't panic at slow growth
Small ferns Even moisture, no direct sun, real humidity
Air plants No soil, but they still need a soak
Succulent trios One pot, three water schedules
Jade plants Bright light, dry spells, long life
Buying guide What survives a normal apartment
How to use these
Each guide answers the same four questions in the same order: how much light, how to water, what soil and pot, and what the common failure looks like. If you only read one section, read the failure section — it is the part that tells you what is happening to your plant right now.
Climate matters. These are written for indoor conditions roughly between 65°F and 80°F with average household humidity. If you live somewhere very dry, add humidity; if you live somewhere very humid, water less and watch for rot.
