Harden Off

3 weeks after LFD

If you are planting Roselle out in cool spring conditions the transplants should be hardened off carefully.

Do this slowly over a week, by reducing the amount of water they get and by leaving them outside for longer periods each day. This helps them to slowly get accustomed to the somewhat less than ideal conditions to be found outside.

In warm summer weather there is no need to harden off the transplants. However you may want to keep them outside in the shade for a few days, so they don’t get sunburned when planted out.
