My weeping willow is dying? In the beginning of spring, my 3yr weak willow was green...

In the beginning of spring, my 3yr weak willow was green and gorgeous, we live in ca. Now it is horribly brown motionless and dry, it gets plenty of river..my gardenr sprayed weed killer and fertilized my front patio twice this year...does this have anything to do next to it dying? How do I get it rear to life? Any suggestions warmth. Thank U
Answers:    Maybe your gardener sprayed weed killer within the wrong direction. If it is truly dying, you need to catch the guy to replace it for you. That is if you are totally sure that it has be getting watered well and truly.
you may want to replant it in a different nouns. they should be in a relatively shaded nouns and do not need loads of wet. good luck.
