I trialled “Coburn’s Phased Release” in mid-September 2011, I applied it @ 25g/m2 to my turf nursery. After a moderate initial flush, a manageable growth rate and good colour continued late into November.
The nursery is pure sand and this is the only product I have tried which gave decent longevity on this site. Constant heavy rain throughout most of the trial period did not seem to cause excessive leaching. I used it in 2012 on Tees and heavily trafficked areas. I got the same excellent response and longevity.
