Plants need at least 10 hours of daylight to grow actively. The period with under 10 h is called the Persephone period.

From To Number of days
Daylight over 10 h 22 Feb 19 Oct 239
Persephone period 20 Oct 21 Feb 126
Plan the year's last sowing of cold-hardy plants in Musteika so they are approximately 75% mature by 20 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 22 Feb – 17 Apr 55 Grow long-day plants like spinach, lettuce and coriander.
Longer daylight 14+ h 18 Apr – 24 Aug 129 High risk of bolting
Shorter daylight 10-14 h 25 Aug – 19 Oct 56 Grow long-day plants
