Delivered as notified with updates and the mixture is very good too! A fairly light loam compared to a more heavy mixture I had been using - which was just what i wanted. Happily recommend CPA.

Delivered a day early despite being updated online that it was coming on the Wednesday. No problem as driver could put it at the side of the driveway, and its too big to pinch! Interesting, mix must have been done when wet, as soil was somewhat in round lumps and the mix wasn't homogeneous as you find in bags but reasonable value in bulk. John Innes can vary considerably between suppliers but it appears to be less sandy than some. Probably would order again following assessment of performance

Prompt delivery on agreed date. Mixture looks superb. Good strong bags which are easy to carry at 40 litres. Too early to tell whether plants will thrive but I can't imagine why they wouldn't. Highly recommend using CPAH.
