What this sheet is for
Move seedlings outdoors gradually and keep a record of what worked. The routine that got this year's plants out unharmed is the one to repeat next spring.
Who it is for
Gardeners and allotment holders raising their own vegetable, flower and bedding plants indoors or under glass.
How to use it
- Give each tray or batch a letter and fill in its row when hardening starts.
- Write the plan you are following at the top: from the seed packet, a book or your own routine.
- Each day, log which batches went out, when they went out and came in, where they stood and whether they stayed out overnight.
- Note any wilting or scorch on the same line, and a week after planting out write how each batch is doing.

Printed under the title: Each tray or batch of seedlings from the day hardening starts to a week after planting out, with a daily log of when they went out, where they stood, whether they stayed out at night and any damage.
Your plan, then what happened. No timetable is printed: how many days it takes, how long the plants stay out and how cold is too cold depend on the crop, the seed packet and your own garden. Write the plan you are following below, then record what actually happened each day.

Questions
How many days does hardening off take?
No figure is printed, because it depends on the crop, the weather that spring and how soft the plants are when you start. Follow the seed packet or your own routine, write it at the top, and let the log show whether it was enough.
Why is there a column for the lowest temperature?
Only for those with a thermometer outside. Your own reading beside a night the plants stayed out, and how they looked next morning, is the evidence for when to leave them out next year. Leave it blank if you have no thermometer.
