The soak-and-dry method
How to water a succulent so the roots drink and then breathe — and how to tell, without a schedule, that the pot is ready.
Almost every dead succulent on a windowsill died of kindness. The plant did not drown in the sense of sitting in a lake; it suffocated, because roots that stay wet cannot take up oxygen. The fix is not to water less often as a rule, but to water thoroughly and then let the mix dry completely before the next round.
Why the calendar fails
A watering schedule assumes a constant: the same pot, the same room, the same week of weather. None of those stay constant. A terracotta pot in a bright room can dry in four days in April and in three weeks in January, in the same house, with the same plant.
So the useful question is not 'how often' but 'is it dry yet'. That is a physical measurement, and you can take it with your hand.
Lift the pot
Water the plant until it runs from the drainage hole, then lift the pot and note the weight. Do it again three days later. The difference is unmistakable once you have felt it: a dry 12 cm pot feels like an empty cup, a wet one like a full one.
For larger pots, push a wooden chopstick to the base and leave it for a minute. It comes out clean and dry when the mix is ready, and cool and dark when it is not.
Water the soil, not the plant
Rosettes and felted leaves trap water. In still air, a drop sitting in a crown is an infection waiting for a cool night. Use a long-spout can and aim at the gap between the pot wall and the plant, or bottom-water by standing the pot in 5 cm of water for twenty minutes.
Bottom watering is slower and harder to overdo, which makes it a good default for beginners and for anyone watering a shelf of small pots.
A working year
| Season | Indoor shelf | What to watch |
|---|---|---|
| Spring | Every 10–14 days | Growth is fast; check weight weekly |
| Summer | Every 7–10 days, or pause in a heatwave | Still air and 30 °C+ is dormancy, not thirst |
| Autumn | Every 10–14 days | The best window for repotting and propagating |
| Winter | Every 3–5 weeks, or not at all | Cold glass and wet mix is the lethal combination |
Three signals that you are late
Lower leaves wrinkle and feel soft rather than crisp; the rosette closes slightly like a fist; the pot is light for two days in a row in active weather. Any one of these means water now. Shrivelled lower leaves on an otherwise firm plant are usually just age, and can be pulled away cleanly.
