Please can you give me some advice I have 30 llelandi conifer trees around our garden and about 15 have gone brown a patch started last year but now spreading have they died completely or will they come back again. Our hedge is very manicured,and the are about 6ft tall and approx 15-17 years old. Please help. Thankyou

All my llelandi died they all turned brown, showed them to a gardening expert at the local garden centre and he said they have drowned, so did a bit of investigating and heard a water leak so called the water board and they found 5 water leaks in some terrace houses back yards near to where I live, so my house being a bit lower down the water ran in to my front garden and that is why they drowned, so now replaced them with laruel bushes
