How long do salad leaves take to grow?
It depends on the season, as the warmer it is the faster the plants grow. In the early and late part of the season leaves take on average 2½ months to grow while in mid-summer, at the height of the season, the growing time is between 6 and 8 weeks. For loose leaf varieties, the growing time can then be anything from 28 to 70 days, depending on the weather. The warmer it is the faster the plants grow.
