Watering by month, not by Tuesday
Most plant care advice quietly assumes you'll water on a schedule like a dental cleaning. Every seven days. The third of the month. Tuesday, after coffee. I get the appeal — a weekly cadence is easy to remember, and it's the kind of thing a checkbox app can model in twenty minutes. The problem is that plants don't drink on that cadence. They drink on a longer one, and it slides around with the seasons.
A monstera in July is a different plant from a monstera in February. Not metaphorically — actually. In summer, with long daylight and warm rooms, it'll go through a pot of water in five or six days. In February, in the same room, the same plant will sit on damp roots for two weeks if you stick to the same schedule. That's how root rot starts: by being on time.
The cadence is a season, not a week
When I plan watering, I don't think about days. I think about months, and what each month tends to look like for a given plant. For most houseplants, the rough shape is something like:
- Late spring and summer — short intervals, sometimes shorter than you expect. Active growth, faster evaporation, busy roots.
- Autumn — intervals stretch. The plant is winding down. You're past the peak.
- Winter — long intervals. Many plants are dormant or close to it. Watering on the summer rhythm is the most common way to harm them.
- Early spring — intervals tighten again as light returns, but slowly. Don't get excited too fast.
That's twelve different watering schedules in a year, not one. It sounds like a lot to track, which is part of why I'm here.
What I actually do
When you add a plant, I ask you for an interval per month — or I'll suggest one, and you adjust. Most plants end up with two or three distinct rhythms across the year: a summer one, a winter one, and maybe a shoulder-season one. You don't have to fill in twelve different numbers by hand; you fill in the ones that matter and the in-between months follow.
From there, the calendar takes over. Each month the schedule shifts on its own — you don't have to remember that February is the slow month for your fiddle leaf, because I do. You just get the reminder when it's time.
Dormant months are not a special case
A lot of plant apps treat winter as a setting, like a vacation mode you toggle. I think that's backwards. Dormancy isn't an exception to a plant's life — it's half of it. The same plant that needs water every four days in July needs it every fourteen in January, and that's not a quirk, it's just what plants are. Treating dormant care as a first-class part of the schedule, rather than an afterthought, means fewer overwatered ferns in March.
What this costs you
Almost nothing. The setup takes a few extra taps the first time you add a plant. After that, you get something most schedules can't give you: a plan that's actually right in November, not just in May.
Plants live in years, not weeks. The calendar should too.
