Trailing begonia

I am worried now about watering the hanging baskets, with the hosepipe ban I will have to climb up the step ladder with some water to do it, and at my age it's not always a good idea, I am not a step ladder climber. my hanging begonia is so lovely at the moment. They are needing watering every other day as we have had no rain for ages.

It's been cloudy bright today and quite warm again.
