I have a lavender border between my path and lawn. It’s never been very successful - over zealous pruning in year 1 I think, plus heavy London clay soil (despite adding grit) meant some plants a bit straggly - tho some have flourished. It’s patchy and looks quite messy. I was thinking of giving it one more year - but might actually give in and change it this year. Any ideas on what a good alternative would be? It’s only a narrow (30cm) border, and I’d like some gaps between plants for kids to go between path and lawn....
