My plants

The journal is empty. Open any plant entry and press Add to my plants, and it will appear here with the day it next needs water.
Nothing here leaves your device.
How the days are worked out
Every plant in the journal carries two watering intervals: one for the growing season and one for the winter rest. The log slides between them across the year on a smooth curve, so a plant is not suddenly watered twice as often on the first of a month, and it reads the curve for your hemisphere, which means January is high summer if you are south of the equator.
Two things you tell us then move the number. Low light stretches the interval, because a plant in a dim corner uses less water; strong light shortens it. A small pot dries faster than a large one, so it shortens the interval too. Every row in All plants shows the sentence behind its own figure, and if you disagree with it you can set your own interval, which replaces the whole calculation and says so.
Feeding pauses through the winter rest and starts again in spring. Misting appears only for plants that genuinely want it. Repotting is measured in years rather than days and lands in the spring, which is September if you are in the southern hemisphere and March if you are in the northern.
Where your list is kept
On this device, in this browser, and nowhere else. There is no account, nothing is sent to us, and we could not read your list if we wanted to. That has one consequence worth knowing: if you clear your browser's site data, the list goes with it. Save a copy from time to time, or send yourself the share link, and you can put it back on any device in a few seconds.
The intervals here are a starting point rather than an instruction. A pot beside a radiator dries faster than the same pot across the room, and the soil tells you more than any calendar can. Use the number as a reminder to go and look.
