How often should you water indoor plants?
The honest answer is that a schedule is the wrong tool. Here is what to check instead.
Stop watering on a schedule
"Once a week" is the most common piece of plant advice and one of the least useful. How fast a pot dries depends on the species, the pot size and material, the light, the temperature, the humidity, and the season. A monstera in July and the same monstera in January want completely different intervals.
Check the substrate, not the calendar
Push a finger into the substrate to the depth of your first knuckle — about 3cm.
- Damp and cool: do not water.
- Dry at the surface, damp below: most plants can wait.
- Dry to the knuckle: water most foliage plants now.
- Dry throughout, pot feels light: water immediately.
Lifting the pot is genuinely reliable once you know its watered weight. A dry pot is noticeably lighter.
How to water properly
Water thoroughly until it runs from the drainage hole, then let it drain fully and empty the saucer. Small, frequent sips leave the lower half of the root ball permanently dry and encourage roots to stay near the surface.
Season matters more than people expect
Growth slows markedly in winter, and a plant that is not growing is barely drinking. Watering at summer frequency through a Jordanian winter is a very common way to cause root rot.
In an air-conditioned room
Air conditioning dries the air rather than the substrate. That means leaf tips crisp while the pot is still wet. If you see brown, dry tips on a plant whose substrate is damp, the answer is humidity, not more water — and adding more water at that point makes things worse.
