Midsummer heat: watering twice a day without waterlogging

A shallow pot in full midsummer sun can dry from wet to bone-dry in under a day, which is why the watering rule shifts from daily to twice-daily for many species once real heat arrives. The risk this invites is not drought but its opposite: a well-meaning extra pass at midday, onto soil that is still damp from the morning, drowns roots that the heat itself would never have killed. Check with a finger before every pass, not the clock. Morning and evening, soil-first — the two-a-day rule is a ceiling, not a habit.
