Houseplant Watering Calculator

Overwatering kills more houseplants than anything else. Pick your plant and conditions for a realistic watering rhythm — then always confirm with the finger test before you water.

How this works

Each plant has a baseline watering interval. We adjust it for the four things that change how fast soil dries: brighter light and summer growth dry soil faster (shorter interval); larger pots, higher humidity and winter dormancy hold moisture longer (longer interval). The result is a range, not a fixed day — soil, drainage and your home all vary.

이 추정은 평균 실내 조건 기준의 일반 가이드입니다. 물주기의 최종 판단은 항상 「흙 손가락 테스트」 — 흙 위 2~3cm가 말랐는지 직접 확인하세요. 화분 배수·계절·난방·개체차에 따라 달라지며, 과습(뿌리 썩음)이 마름보다 더 흔한 실패 원인입니다.
