Bus seeds!
Isn't it a bit mischievous to start sowing seeds already? Spring is a long way off! Yes, but you can actually get a false start. We sow seeds for plants that are first allowed to grow indoors, and then we can put them outside when it gets warm and bright. You will get both wild and tame (?) seeds to sow.
The activity is free and you do not need to pre-book your place. Leisure groups may need to split up and take turns participating so that everyone gets a seat.
