An earlier reference to watering, and the possibility of rain, reminded me of something Alan Titchmarsh said... an inch of rain (which we rarely get all in one go in summer) will penetrate the soil to a depth of 9 inches. Whilst this is useful it is no where near enough, and unless we get continuous and frequent rain , we must keep on watering. Pots and tubs in particular get almost no benefit from rain as much is shed by the leaves without touching the compost. Having said that plants seem to smile more when they have had a good drink of rainwater.
Personally, I don't use the spray attachment when I water. I remove it and water using the end of the hose at the base of the plant. If I was thirsty I would much rather lie beneath the tap, than run around the garden with my mouth open in a storm!
