Growing Season
The time when plants are most active is called the growing season and is usually defined as the part of the year when the average temperature exceeds a certain level. The relevant critical temperature level varies for different types of plants, but one value often used in both agriculture and forestry is +5 C. Following this definition, the length of the growing season varies from just over 200 days on the west and south coasts and on Öland, to only about 100 days in northernmost Lapland.
