[quote=jonbey;868062]I have some very persistent moss and clover, plus some other horrid weeds, in my lawn. My parents helped me treat is a few years ago, which helped, but the problems are back with a vengeance.

Apart from ripping it up and starting again, what should I do?

The lawn is 7 years old, was turf, probably cheap, and on good soil, but likely full of builders waste (the borders and patio were a nightmare to dig).

You have weeds and moss because of 1/ the way you care for your lawn 2/ the local environment - perhaps shady or damp and 3/ the climate

The fact the lawn is 7 year old cheap turf is not going to make a lot of difference. Premium turf would do exactly the same in the same conditions! The builders rubble may or may not be a problem and your 'good soil' may be a problem if it is 'good clay soil'!

If it's not the soil or rubble causing the problem, and it certainly isn't the cheap turf then why rip it up? You need to a/ learn how to care for the lawn 2/ try and change some of the 'moss & weed causing environmental conditions' 3/ apply weed and moss control measures.
