Houseplants: light, water, soil

A plant needs three things: light, water and air for roots. The main mistake is overwatering — roots without air rot. Finger test: top 2 cm dry → water. Light matters most: "shade-tolerant" does not mean "loves darkness", it means "endures shade". In winter all plants rest — water less, do not fertilize.

• ●Yellow leaves = usually overwatering, not "disease"
• ●Drainage + a pot with a hole solves 80% of problems
