I planted about 10 Miss Canada lilac bushes early this spring. I just bought the house and before that there were some older lilac bushes that were dying. We dug all of them out and put fresh soil and manure in. I watered the lilac bushes about every other day all summer long. I live in Boise Idaho and we have hot dry summers so I wanted to make sure they got enough water. Now it's late summer and the lilac bushes seem like they're shriveling up and dying. Leaves are hanging and curling brown. I did fertilize with bonemeal but it didn't make any difference. I'm speculating if the soil is dead and I didn't dig deep enough when I put the fresh stuff in or if I'm simply overwatering and the roots are drowning. It was a pretty big investment buying all the starters from the nursery. If anybody has any advice it would be greatly appreciated!
