I never feed and mulch my Laurels and they grow like mad. I cut bits off when I think it needs doing, but it seems to need doing more than I do it as they are now too big!
Pruning can be done at almost any time of year. The only time to avoid is when there's frost and cold weather imminent, so it's probably best to leave them for a couple of months anyway.
Mulching can also be done at any time, but it's best to do it after there's been sufficent rain, so that the mulch retains that moisture. Spring is ideal, but you can add it throughout the year and that will gradually break down and feed the soil too
I'm the same as B. Lizzie - they don't get much attention here, other than pruning to keep them in order.
I live in west central Scotland - not where that photo is...
