I have 2 tall large water butts, quite attractive cream columns and they last for very many years, had some in the last house so tried and tested. I also have at least 5 watering cans and don`t use a hose
I have a new small garden ie 3 years old and it now is a micro climate, full of greenery and 7 small trees. All through this time I have been adding humus, at the least it has been composted bark and the soil is now holding onto water at deeper levels
I have been aiming to make it as drought proof as possible hence trees, apples and rowans and roses and ground cover like sedums and geranium. I have colour with echinacea and roses. Definitely it is working wrt water retention and the micro climate, asparagus beds, cause light shade which protects most of it
Re pots yes me too. I now only grow lavenders and agapanthus in my normal pots. I have 72 hanging basket strawberry plants in many trough planters but they are self watering and right now only need a fill once a week, they are on tier stands so are easy. I have 2 japanese maples in 2 large self watering pots, last watered a month ago
soil structure is key really and my veggies don`t need an excessive amount of watering
