Hi All, I need some advice on top dressing a lawn. My front lawn has a problem with weeds which I have just dug out recently. I realise I can blitz it with weed & feed in April but will top dressing do any good to prevent weeds ? I have read where you are supposed to top dress in Aug / Sept but can you do it in April or is it a waste of time ? I have seen a mix of compost & sharp sand mentioned, has anyone got any useful tips. Thanks in advance.
