Step 1

Acclimatising

Acclimatising plants is relatively easy. Once seedlings have grown so large that they need to be potted into bigger containers or placed outside, you have to ensure that they’re not going to be shocked by cold temperatures. This is done by moving trays of young plants outside during warmer days. As the evening draws in and temperatures drop, seedlings should be brought back into the warmth.

Step 2

Repeat

This process should be carried out over a number of consecutive days to ensure that plants become used to varying temperatures so it take 5 to 10 minutes a day for about a week. If there is still a chance of frost, it’s a good idea to keep bringing plants into the warm each night. Alternatively, after a few days of acclimatising, you can leave plants in a frost-free cold frame or greenhouse overnight. Cold frame lids and greenhouse doors can then be opened during the day to allow ventilation, before plants are once again protected at night.

After all chance of frost has passed, plant vegetables or flowers into their final locations.
