Dead heading will encourage flowering for longer. Are they a year old or more too? If they are, they flower a bit earlier and for longer!
I have some new ones this year and they are only just starting to flower now

Take the flowering spikes off the Lupin don’t let it go to seed, it’s putting energy into those seeds and won’t flower again if you don’t cut them off, it will flower longer if removed
I don’t grow Delphiniums but they say if you cut the flowering stalks back , you usually get another flush in late summer
Regarding the Lupins
If you decide to forfeit a second flush or more flowering in favour of seeds it can be an interesting part of gardening seeing what colour flowers the seed plants produce, they rarely come out same as the parent plant
You could of course get best of both worlds, cut them back and later on leave one flower spike to go to seed then harvest the seeds
I’ve done this myself, it’s great waiting to see what you’ve produced by the way of a hybrid

The rose will if it’s sufficiently mature and you keep up the deadheading
