Soil additives
My partner decided to grow dahlias for the first time this year. Most of the tubas have all sprouted and are looking good to be planted soon. I have been clearing out areas of the garden but not sure if I need to add compost, manure or anything else. Ground was quite hard to start off with but I have worked it with a spade and it seems like it’s mainly old topsoil. Any hints would be appreciated
Thanks
