Full disclosure - I know nothing about gardening!! Just moved house and our lawn has borders all the way round about 50cm out from the fences. There’s some bushes dotted around the edge. I think the previous owners put in lots of bedding plants but I really would prefer something that, once planted, provides colour year after year.
So I’m going to invest in some perennials or annuals ( I don’t know the difference). In my mind I’d like the shrubs to all eventually sort of merge so you can’t see the soil in the border. Is that right ? Is that what established gardens have?
