Winter lettuce is only available from the 5th to the 15th. posted in September.
The so-called winter lettuce develops the heads only in the following spring. Since it is exposed to all weather influences outdoors during winter, it must not get too big in the winter. Sown too early or. planted, winter lettuce usually perishes due to rot. Sowing takes place on open-air seedbeds, as with ordinary lettuce.
