From To Number of days
Daylight over 10 h 27 Feb 15 Oct 230
Persephone period 16 Oct 26 Feb 135
Plan the year's last sowing of cold-hardy plants in Fägred so they are approximately 75% mature by 16 Oct when daylight drops below 10 h and growth starts to slow.

Daylight periods

Long-day plants like lettuce, spinach and coriander bolt when daylight gets too long. Plan sowing and harvest during periods when daylight is shorter (10-14 h). Early spring or late summer sowing gives the best results.

Season Light Period Days Advice
Shorter daylight 10-14 h 27 Feb – 13 Apr 46 Grow long-day plants like spinach, lettuce and coriander.
Longer daylight 14+ h 14 Apr – 28 Aug 137 High risk of bolting
