My 2 Weeping Cherry trees that I bought from Bunnings appear to be dying with the leaves shriveled and gone brown, they were going great for the first few months with a nice display of blossoms and even a few fruit, they are planted with the suggested soil mix from Bunnings and perlite, they are in full sun and are on a watering system which delivers the suggested water to each plant. Are these now dead since they should have the summer foliage on them?
