gerber daisies

I've planted 4 gerbers daisies in compost in a large pot on my daughters terrace in barcelona last weekend. I put stones in the bottom for drainage. The flowers are wilting even though they have an irrigation system and watered as well. Any ideas what to do to revive them. Thanks

 

Not sure how long ago you planted them. If recently, most plants check when potted. If not, I would cut down on the watering.
