Good morning, this is my first first post, as well as my first garden, so please excuse me if I ask some daft questions!
We have a lot of white Allysum growing in the garden, and although pretty it is now rather taking over. I keep readng that it is a hardy annual plant, but would someone be kind and explain what this means in practice? Should I leave some clumps in the ground so it comes back next year, or dig it all up to make room for some spring plants, sowing fresh seeds next spring?
Many thanks for your help
