After following the advice on the site I purchased what should have been sufficient clover seed to cover the 66m2 However, on receipt of the seeds the advice was tremendously different and it would take a huge amount more than I had purchase. I emailed them with this and they said they acknowledged the lack of clarity and would change it to reflect this but this in no way helped me resolve my issue as I am unable to purchase the required amount due to the massive cost in comparison to the original advice. So very disappointing and therefore unable to recommend
