How often to water indoor plants

Most of the plants we replace drowned. Here is how to stop guessing and start reading the soil.

Forget the weekly schedule

A calendar reminder waters the calendar, not the plant. The same pothos that drinks every five days in July can go three weeks in January without complaint, because light and temperature — not the date — decide how fast it uses water.

Replace the schedule with a check. Once a week, put a finger two inches into the soil. If it is damp, do nothing and check again in three days. If it is dry at that depth, water thoroughly.

How to read the soil properly

The top half-inch dries out within a day of watering and tells you almost nothing. Two inches down is where the roots are, and that is the only depth worth trusting. A wooden chopstick pushed into the pot works just as well as a finger — if it comes out clean and pale, the soil is dry.

Weight is the other clue

Lift the pot when you have just watered it, then lift it again a week later. That difference in weight becomes the fastest check you own, and it works through decorative pots where you cannot reach the soil.

Water thoroughly, then stop

Half-watering is the most common mistake after overwatering. A splash wets the top inch and leaves the root ball dry underneath, so the plant lives on the shallowest roots and never settles. Water until it runs from the drainage hole, wait ten minutes, then pour away whatever is left in the saucer.

Never leave it standing in water

Roots need air as much as water. A pot sitting in a full saucer suffocates from the bottom up, and root rot is almost always fatal by the time the leaves show it.

Thirsty or drowning?

They look alarmingly similar: limp leaves, drooping stems, a generally sorry plant. The difference is in the soil and the leaf edges. Dry soil with crisp brown tips means thirst. Wet soil with soft yellowing leaves, especially lower ones, means too much water — and the fix is to stop watering, not to water more.

Adjust for the season

From roughly November to February most houseplants barely grow. They are not sick; they are resting, and they need noticeably less water. Cut back to roughly half your summer frequency and resume when you see new growth in spring.

Radiators and air conditioning change everything

A plant above a radiator or under an air-conditioning vent dries out two or three times faster than the same plant across the room. Move it or check it more often — those two spots account for most of the winter losses we see.
