Answer: I really need more information to help you better, but here are some general thoughts. Shasta daisy should be moved in fall or late winter. If you moved your plant recently it may be suffering from the transplant shock in the hot weather you have been having in southeast Texas. Make sure it has enough water but don't keep it too wet. You'll just have to wait and see if it will pull out of this one.
Impatiens love a shady, moist spot. Droughty soil can really stunt them. Too much sun will burn the leaves. There are few leaf diseases they will get in your area. However, if they are getting sprinkler watering, it is possible that frequent wetting has promoted a fungal or bacterial leaf spot. If you feel their location is good, a "rescue" option is to trim off the diseased tops and discard them. Then water well with a liquid plant fertilizer and wait for them to bush out and regrow.
