Is it too late to put nitrogen on my lawn, also I have a green beech hedge 90% of it is very strong but 10% directly under a large tree is weak. Is there any feed I can put on this 10% to help them.
I just saw the email from garden.ie where it said 10-10-20 did not have enough nitrogen for feeding a lawn after the winter. I put 10-10-20 on my lawn last week, is there any way to boost the nitrogen now or could I put 20-10-20 on now or would I damage the lawn by over feeding.
