Sowing calendar January

Brrrrr, January is generally a cold month and sowing seeds outside is therefore, in most cases, not a good idea. However, January is the ultimate month to prepare for the summer. Do you have a small greenhouse or conservatory? Then at the end of January you can start by pre-sowing various types of vegetables. This is especially important for plants that need a long growing season to develop. By the end of January the days are thankfully a bit longer and brighter again.
