Durston market this pelleted fertiliser for all garden use. I used this product on my lawn after it was decimated by building work and it made a dramatic recovery. Other times I have used this in flower tubs, mixing it with the compost and the results look suspect. ie, my sweat peas have never looked so sick ? What troubles me is that it has no mention on the container, what the source of the material its made from. Nor does the Durston web site ? Normally for this type of pellet it would be chicken waste. I have written to the company asking this question, but I fail to get an answer. Why are they so secretive. I just hope its not waste material form the local sewage works ?
