Why a weekly calendar instead of a per-plant schedule
A per-plant schedule is the right record of how often each plant wants water; a weekly calendar is the right tool for the morning you walk past the shelf wondering what is due. Keep both: fill the Interval column from your plant watering schedule, pencil the planned days into the week, and tick them as you go. A week with no ticks for a plant is the clearest overwatering prevention there is — you can see that it is not due.
Ticks are for watering, but the sheet works just as well for the check: write a small 'c' on the day you tested the soil and found it still moist. After a month, the pattern of c's and ticks shows the real interval better than any care guide.
Seasonal adjustment
Intervals are not fixed. As days shorten in autumn, most houseplants slow down and their soil stays wet longer; stretch each interval by a few days to a week and move the planned ticks accordingly. In spring, growth restarts and the ticks move closer together again. Heating season dries the air and can shorten intervals for small pots near radiators even as the plant's growth slows — the soil test wins over the calendar every time.
Turning an interval into calendar days
How to plan the week from the Interval column. Shift everything by a day if a plant's soil is still moist on the planned day.
| Interval | Pattern on this sheet | Example |
|---|---|---|
| Every 3–4 days | Two ticks per week, three days apart | Mon and Thu, or Tue and Fri |
| Every 5 days | Rotates through the week; plan from the last tick | Mon → Sat → Thu (next week) → Tue |
| Every 7 days | Same day every week | Every Sunday |
| Every 10 days | Alternates: one week one day, next week three days later | Mon, then Thu of the following week, then Sun of the week after |
| Every 14 days | Same day every other week — mark 'off week' in Notes | Sunday, skip a week, Sunday |
| Every 3–4 weeks | Write the date due in Notes rather than ticking a weekday | 'Due ~Nov 12' for aloe or cactus |
For intervals of 10 days or more, the per-plant schedule sheet is easier; use this calendar for the plants you water weekly or more.
How to use this sheet
- Print the PDF — one sheet per week — or laminate one and use a dry-erase marker.
- List every plant you water at least every two weeks, and write its interval in the right-hand column.
- At the start of the week, pencil a small dot on the days each plant is planned, using the interval table.
- On the day, check the soil first; tick if you watered, write 'c' if you checked and waited.
- At the end of the month, compare the ticks with the intervals and update any plant whose real rhythm is different.
Questions
Is this sheet really free?
Yes. The PDF is free to download and print — no sign-up, no email, no watermark.
Should I water all my plants on the same day?
Only if they share an interval. A fixed 'watering day' is how snake plants and succulents end up watered weekly. The calendar lets you keep one routine time of day while each plant keeps its own days.
How do I handle an every-10-days plant on a weekly sheet?
Alternate: tick a day this week, then three days later on next week's sheet. The interval table above lists the pattern for common intervals, and the notes column holds the date for anything longer.
Can I use this for fertilizing too?
Yes — write 'F' instead of a tick on feeding days, or keep a separate plant fertilizer schedule sheet if you feed on a monthly cycle.
Is there an app version?
Yes — PlantLog for iPhone tracks watering, fertilizing, and repotting per plant with reminders, so the schedule maintains itself. Core is free, no account needed, and your data stays on your device.
Want the log to analyze itself?
