I planted a new Laurel (english) Headge last autumn. It sailed through the winter & snow. Had a few catterpillars to pick off early spring & then it has taken off! Lots of new shoots & leaves putting on growth outwards & upwards. But everytime I leave the house I find yellow leaves on the ground and 1 or 2 lower leaves have turned yellow on each plant & they just fall off when you touch them. No sign of insect damage, they just look as if something has sucked the life out of them. HELP!! I lurve this hedge, it's so green & shiny it just makes me want to smile whenever I leave or enter the front gate! Only thing untoward is a lot of ants all over the place (tried usual methods) but can't find a nest anywhere. Other thing is a very large tree on street outside and I found small roots from that when I dug out to plant hedge. Anyone have any ideas? Tried to attach photo but it said it was too big!? Don't know how to make it smaller.
