I have grass growing up through my heather. The heathers were planted several years ago and we used a black membrane to stop weeds. However the grass is shooting up through it and when it try to pull the grass it breaks and I am unable to get the roots. Do I need to dig it out and start again?

Mix up Roundup as directed for a spray, say two litres, or ready-to-use.
Put in a bucket, and put on rubber gloves.
Hold the grass on a gloved hand and wipe across it with a damp sponge. Repeat this every 3 weeks until all grass is withered.
Damp sponge only… to avoid drips on to heathers.
