Q.Asters are all yellow and look dead
We recently replanted store bought asters into our garden bed and immediately they seem to have died. All the flowers are dead and the foliage is yellow and way too dry. What do you think the problem is, and how can we revive them, if at all?

Now will not be a good time to plant these. It is still far too warm.
These should be planted in Spring in your area, as the warmer weather will prevent them from taking to the transplant. Compounding the issue will be overwatering in attempt to compensate for the dry and heat. This leads to infections.
Your best bet will be to treat with a fungicide, and hope for the best. They may or may not make it until next year. Should they not come up by mid spring next year, you will know that you should replant then. Waiting until this time of year will usually end up like this.
