My lawn was sown a year ago and I applied fertilizer (agricultural – due to size of lawn) in late April/early May. It was nice and green but now the fertilizer is gone and there are alot of white patches – the soil/drainage is not great. I was in to the garden centre and they reckon it is too late for another dose of agricultural fertilizer and only other suggestion was standard lawn feed. I was under the impression there was a specific Autumn lawn feed which I could apply know to strengthen the grass before the winter months and bring back the greenness. Any recommendations on that front?
