Seed Sowing Calendar
Plan a growing year on one page using the sowing times that apply where you garden, rather than a calendar printed for somebody else's climate.
Garden and growing · GG-03
A free printable greenhouse log — minimum and maximum temperature, watering, feeding, ventilation, pests seen and what was sown, one line at a time.
One page. Choose your paper size — both versions are laid out identically, so neither one gets shrunk to fit.
Print it and write on it

The fillable versions have real form fields — open them in any PDF reader, type into them and save. Printing help.
Turn a greenhouse from a place things happen into a place with a record, so a bad germination or a lost crop can be traced back to the week it went wrong.
Greenhouse, polytunnel and cold frame growers, and anyone raising plants under cover for the first time.
One page, top to bottom:
Printed under the title: A running log for a greenhouse, polytunnel or cold frame — the overnight low and the daytime high, what was watered and fed, how it was ventilated, what pests turned up and what was sown.
Read it at the same time each day. A min/max thermometer is what makes this sheet worth keeping. Put it at plant height and out of direct sun, reset it at the same time each day, and the readings become a record you can compare rather than an impression.
Write-on lines: Greenhouse / tunnel · Glazing or cover · Year · Heating, if any · Thermometer position · Water source
Table, 13 rows: Date · Min · Max · Watered · Fed · Vents / shade · Pests seen · Sown / potted on
Because the reading you happen to take is rarely the one that mattered. The damage is usually done by the low overnight or the high while you were out, and a min/max thermometer is the only way to see either of them.
What you used and how much of it. Feeds differ in strength and in how they are diluted, so the sheet does not print a rate — it records the one on your bottle and what you actually mixed.
Plan a growing year on one page using the sowing times that apply where you garden, rather than a calendar printed for somebody else's climate.
Know which heap is ready and what has already been spread where, instead of guessing at both every spring.
Get the plot down on paper to a consistent scale, so bed lengths, seed quantities and next year's rotation can be worked out in the warm.
Turn a vague intention to look after the house into a page you can tick off, so the jobs that only need doing once or twice a year actually get done.
The same subject, with a version you can fill in on screen.
Total weight and count harvested over the season, added up for you.
Which parts of the garden need watering and what is in each.
Where each plant is, which matters once there are more than a dozen.
Every sheet, binder, game and puzzle on Upkeep Papers is free to download, with no email and no account. Making them is not free: each one takes days of research, design and checking, and the site costs money to run. If something here saved you time, you can buy us a coffee. It is entirely optional: nothing is locked, and nothing changes if you don’t.
