Hello, beginner gardener here... I'm confused as to how to best look after my borders. I want to build up soil overall as is all looking a bit sorry and some bulbs (tulips I think) have risen to the surface. Can I just pop down some compost or should I do a mix of compost and top soil? And I understand I should mulch. I assume that goes on top of the soil/compost. But will it stop bulbs and new plants coming through? Are only supposed to mulch where you know there are definitely no plants expected?
