Watering

I'm not on metered water and have a few hundred litres of butt water capacity (I plan on increasing this substantially soon as rain water is better than tap). I try to use rain water for things like citrus (we have a lemon tree outside in summer, orangery in winter) and a few other plants who prefer rain water to tap.
Those in pots at the moment are getting watered every other day (fairly big pots) anything that looks wilty gets more regular, veg plot is getting a good dose 1x weekly unless the beans start to look in need, potato sacks are getting some every other day, veg tug with salads in getting every other day.
The apple tree planted this last winter is getting every other day good soak as is looking a bit fragile and I don't want to lose it.
Everything else, ie ornamental beds, fruit bushes and established trees are being left to their own devices. All my soft fruit is coming on and we've not had any rain for weeks either.
