Late October in an Irish garden: what to cut, what to leave, what to plant, and what to clear before the first frost and the first storm. From the Irish sources that know the difference between an Irish autumn and an English one.

IN SHORT
There is no fixed last-cut date in an Irish garden; it depends on the ground. The Irish Garden's October guide says keep mowing as needed as long as the soil is not soggy, because grass left uncut after October can get very long by spring. Raise the blades a notch. Apply an autumn lawn fertiliser now, before it gets too wet, to keep some winter growth going; sulphate of iron deals with moss. October is the month to rake out dead thatch and moss, aerate compacted areas with a fork, overseed thin patches and recut the edges. Rake leaves off the grass; left on, they kill it in patches.
September and October are the window for most spring bulbs, planted at two to three times their own depth, pointed end up, two bulb-widths apart. The exception is tulips: the Royal Horticultural Society of Ireland advises late November or even early December as ideal for Ireland, because tulips tolerate the dry and are less likely to get tulip fire when planted into cold soil. Daffodils can still go in through November, and Mairead Lavery in the Farmers Journal notes that tulips can wait until January if the ground is wet.
Roses, trees, climbers and shrubs, raspberries, blackcurrants and fruit trees all go in from now, and from November they come bare-root, cheaper and in better variety than potted. Dig the hole wide rather than deep, do not bury the graft, stake on the windward side and water in even if it is raining.
Rake leaves into a pile in a corner, or into a wire cage, and leave them; by next autumn they are leaf mould, the best mulch there is and free. Pick leaves off paths as well as grass: wet leaves on a path are a slip hazard, particularly for older people. Keep the compost heap damp but not sodden, cover it in heavy rain, and turn it if you have the energy.
Then look up. Gutters full of leaves overflow down the wall; drains full of leaves flood the patio. Rentokil Property Care's advice before winter is the same as every insurer's: check the roof tiles and make sure gutters and drains are clear and flowing before the first big rain.
Autumn storms arrive with little notice. The storm advice from PTSB and others is simple: secure garden furniture and anything loose, take down trampoline netting, weigh down or rope anything that could become a missile, bring light ornaments and tools inside, lock gates and shed doors, park the car away from trees, and clear drains and gutters again afterwards when it is safe.
Met Éireann does not publish a typical first-frost date, and the record shows why: in 2024 the first air frost of autumn came on 13 September at Mount Dillon, the earliest in 32 years, and by the end of that autumn every station had recorded ground frost. Plan on the first frost any time from now.
One more check before anything is cut, strimmed or moved: hedgehogs. A pile of leaves or sticks in a corner is a nest; so is the space under a shed or decking. Check long grass before mowing or strimming, do not push the mower under hedges, leave a metre of rough margin somewhere, skip slug pellets, and cut a CD-sized hole in the bottom of the fence so they can move between gardens.

Not in the closed season, and burning garden waste is restricted all year under waste regulations; councils' recycling centres take green waste for a small charge. Leaf mould is the better use anyway.
October is the month the Irish guides give for sowing and turfing; after that, wait for spring unless the weather stays mild.
Shorten tall stems by a third to stop wind-rock, and leave the proper prune until late winter.

Found a hedgehog under the leaf pile last November exactly as described. Left it. It was gone by March.
The tulip advice is right for here. I plant them the week after the Christmas lights go up and lose far fewer to rot.
Did not know the council charged for green waste. Explains the price on the last quote.
