Me, too, but with laundry-detergent bottles, not milk jugs.
And of course, any time a hose and a watering can are near each other, I leave the watering can full.
I also leave a jug or two at the far end of the hose's reach, and any time I drag the hose that far to water, I also refill those jugs. In-between hose-dragging sessions, I have a few gallons handy for the dryest spots.
I started that habit when I tried to grow some semi-aquatic "Water Spinach"
/ Ipomoea aquatica. I tried to water it at least once per day, or twice. Even so: "forget about it!". I think it was both too dry and too cool (semi-tropical).
I also keep both a jet-or-mist nozzle and a Y-fitting with valves on the end of the hose. After dragging the hose as far as it goes, I can use the jet setting to give a little water to more remote spots, but that trades off distance for a lesser volume (rate) of water.
But the spare valve on the Y-fixture will shoot a vast amount of water rapidly, a lesser distance. I can make that a heavy stream or a broken-up heavy spray by closing the valve just a little bit. That way I can very quickly give bushes or a wide area a little water during the driest spells.
