I'm sorry, Patrick, I don't know what you mean by 'cores'? Can you explain please?

I think I've worked it out Bamboo, when you use a lawn aerator you end up with little cores of turf. I don't see how the cores can be used to fertilise the grass though, add them to your compost.

Or are you asking if you can use your law aerator to apply fertiliser to your grass Patrick? In which case no.

Oh right, so Patrick's talking about aeration - I just couldn't work it out, ten out of ten for clairvoyance, MG, lol! If that's right, no, Patrick, is the answer.

Seems to be a day for it on GoY Bamboo... some very cryptic questions.
