We have a polytunnel. At 17m x 9m its footprint is quite a bit bigger than the 2-floor area of our house. At one time we had a straggly grapevine trained up a trellis inside the tunnel. A friend, who knows a thing or two about wine came to view the tunnel when it was new and the plastic was clear and clean. I asked him: if were were to propagate our vine and have a 17m run of plants suitably pruned and fed and cared for, how much wine might we get in a good year? Oh, he replied, a bottle a day with a following wind. We contrived to kill our little vine shortly thereafter. But for nearly 20 years, we've had on-again off-again success with green beans and tomatoes and courgettes. And a mighty triffid of a rosemary bush.
We do have a garden-tap in one corner which ultimately comes from our domestic 30m deep borehole but I'd rather use rainwater which falls on the plastic and gets guttered into various receptacles. Years ago, I bought 50m of perforated pipe with the intention of subterranean drip-feeding our ~10m long 'middle bed' where we most often grow the beans. But a different know-it-some pal assured me that such a project would be futile unless the pipe was perfectly level, Otherwise the water would just pool at the lowest point and everything else would be Sahara. So I'm still slopping out water into the bottomless buckets into which the various veg are planted.
It rained on Saturday 27th June 2026 and I used that to top off all our water containers, down to the pair of 10lt plastic watering cans. Circled L is our Outside IBC, which is 2m higher than the plant roots it serves and the 2-wheeled stable barrow whc can double-job to hold ~250lt water. At this full capacity, we have a reservoir of close to 3 tonnes. That sounds like a lot, it is a lot. One tonne is about what I need for drinking in a year. But IF we have 3 dozen bucket-beds for veg ANDIF they get ~3 lt every time they're watered THEN 1 tonne will only last 10 days.
But this year, it didn't rain again until a 25 minute Summer downpour at tea-time on Weds 29th July; and again more sustained on Mon 3rd August. By 29th July we had more-or-less drained our reserves and I was tap-topping up the big-blue wheel barrow with cool clear well water. And leaving it to get to 'room-temperature' for 24 hours. That 29/07 shower delivered at least 120lt of water. The steady drizzle on the afternoon of 03/08 has put 500 litres into the Outside IBC and as much again has been captured in other containers.
But we've had most un-Irish multi-week rain-free spells in the Summers of 2018, 2023, 2025 and now 2026. The Beloved says I'm too old to be heaving buckets of water about. But I demur: I'm not about to pay ready money at a gym to get a similar workout.
I don't keep good records of when it rains, because it's Ireland. But I do notice when the weather goes all Ancient Mariner [With throats unslaked, with black lips baked / We could nor laugh nor wail/ Through utter drought all dumb we stood . . .] and the grass turns crisp and yellow. We are close enough that daily rainfall records from Alan O'Reilly at CarlowWeather are a pretty good aide memoire for past rainfall
