Step 1: check the soil
UConn extension's test is to push a finger about an inch into the mix. For a chopstick version in winter, the University of Vermont suggests that soil sticking to it means skip watering. Sources: UConn Home and Garden Education Center, Houseplant Watering Recommendations (homegarden.cahnr.uconn.edu), checked 2026-10-13; University of Vermont Extension, Houseplant Care During the Winter Months (uvm.edu/extension), checked 2026-10-13.
Step 2: tell PotPal
- Still damp? Tap Not dry yet. On the notification or on the home and detail screens, choose to wait 2, 4 or 7 days. It is not counted as a watering.
- Dry? Water thoroughly and tap I watered. Water until it drains, and empty the saucer.
Step 3: let it adjust
This is PotPal's own behavior. After two signals in the same direction, for example Not dry yet twice in a row, PotPal changes that plant's interval by a day, capped at plus or minus the larger of 2 days and 30 percent. If a plant's reminders keep arriving early, it will drift toward a longer interval.
The plant's detail page has a Why this interval view so you can see the factors behind the number.
If the reminder is always early
- Check the pot: oversized pots and plastic or glazed pots hold moisture longer.
- Check the season: growth slows in winter, so soil stays damp longer.
- Check the light: dim spots dry slowly.
