Q.Yellow area of lawn
A large semi circle area of my lawn has turned yellow. It is very spongey, so I have raked off a large amount of moss and spiked the area. I have also noticed that some aquilegia, a delphinium and a hydrangea planted nearby have pale foliage and look to be wilting. Any suggestions?
