I use raised beds with the square foot method and containers.Even here I still will have plants that will start to droop by the time I come home. I've done some automatic water lines but always seem to get an issue with them the dogs probably don't help. I was trying to get other ideas and came across the terracotta pots. I think I am gonna try it next year. The water/nutrients would be at the roots where they need it. And I think it will help save water.
Maybe try a raised 5 gallon bucket on each raised bed that you connect a soaker hose to? Then you just fill them up in the am and you should have enough H2o to last the day.... I say should! Lol
