We relaid our lawn in April.
What kind of turfgrass?

Didn't say. Very cheap but growing well at the time. I did wonder whether
it would last - the soil it was growing on was appalling, half clay half
pebbles.

It's hopelessly overshadowed by tall conifers
(we're going to get them cut back this autumn

What kind of conifers? You do know that they don't grow like deciduous
trees,
right? You can't prune them the same way. Other than cutting out the
deadwood,
they don't really need pruning. If you "top" them, they'll look like a
shrub
forever. Where you remove limbs, they won't grow back.

I know all that, yeah. We're getting it done professionally. (They seemed
to think it was possible.)

but didn't manage it last
autumn), but at least it had as good a soil as possible - large amount
of
composted manure dug in, and a full dose of organic fertilizer pellets
(balanced).

Please explain what a "full dose" is, as well as the specific "organic
fertilizer pellets".

Lakeland General-Purpose Organic Plant Food, 8-8-8. (Didn't have the box
handy last time I posted.) I used 75g/sqm which is the maximum dose as
specified on the box. The point is that it was supposed to last it longer
than that.

I'd have said that that ought to last it for months before it
needed feeding again. It was somebody else's idea to deg it with
chemical
lawn fertilizer last week (some stuff called Aftercut, I forget the
details
but pretty strong).

It's not strong at all. It's 3-1-3 + 2% iron
It's basically a waste of money. You get an immediate greenup from the
iron, but
the 3-1-3 is crap.

Well, it wasn't done evenly enough, and killed off
several patches of the lawn.

I doubt that's what killed off the several patches of lawn. You can put
that
crap out by hand. You'd have to have one helluva pile sit in one spot for
quite
a while for it to do any damage.

Well, the grass died off the day after the fertilizer went on, in exactly
the places where there was most fertilizer. Might have been a coincidence,
but it's a pretty good one. Maybe it was the iron. Didn't use anything
else at all.

How often do you really need to feed lawns, anyway?

Totally depends on what kind of grass, as well as your location.

Before it was relaid we
hardly ever used to get round to feeding ours, and the sunnier part
thrived
for several years until it got very compacted.

LOL So, instead of dealing with the compaction by aerifying and
top-dressing,
you replaced the lawn? When your car gets dirty, do you just go buy a new
one?

OK, OK, we should have spiked it more often. (Not that it ever seemed to
make much difference). But we didn't, and one side of it was slowly dying
off anyway from too much shade. This year it had got to the point where
there was hardly anything left, so it seemed easier to cut our losses and
start again.

Before the fertilizer incident, the new lawn was growing fine. But it
did
keep getting these squishy, flattened brown patches about six inches
across,
for all the world as if somebody had ground it in with their foot. Never
come across those before. Can anyone explain?

Not without more information, and perhaps some photos posted online and
linked
here.

Can't help you there, I'm afraid. The above describes them exactly, and I
can't take any pictures now because they were covered up by the other thing.
They appeared any time, any weather, as far as I could tell.
As regards location: Lancashire. Wet, basically.
