Courgette leaves wilting when hardening off
Hi all. I’m very new to gardening so go easy on me! I have grown 5 courgette seedling in a greenhouse which are now ready to be planted outside (I may have left them too long as the are fairly big now - 4/5 leaves each). I started the hardening off process today, they have been in the sun for about an hour and the leaves have started wilting. Granted it is a very hot day - is this because of the direct sunlight? Shall I put them back in the greenhouse and leave for the rest of the day? If anyone has any tips on the rest of the hardening/planting process they would be very much appreciated!
