Semetti are a bit odd, aren't they?
I have experienced with them a little over a couple of years. They are not too hardy yet flower best in early spring so we need to be careful about frost. They do not like hot weather or the summer season...I think.
You can cut them back now and they will flower again but on much shorter and less impressive stems but I thought they weren't worth growing then.
Watering? Offen they are in pots too small for their size so I always pot on and water well.....in spring.....but I don't think the issue is watering now. Their time is up.
I think it's better to regard them as spring or early summer bedding and then dig them up. Replace with something that flowers in the summer
