From To Number of days
Daylight over 10 h 3 Mar 11 Oct 222
Persephone period 12 Oct 2 Mar 143
Plan the year's last sowing of cold-hardy plants in Ånge so they are approximately 75% mature by 12 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 3 Mar – 9 Apr 38 Grow long-day plants like spinach, lettuce and coriander.
Longer daylight 14+ h 10 Apr – 1 Sep 145 High risk of bolting
