Watering the Big Bag Bed is not too different from watering hard-sided containers. For all containers watering frequency depends on a number of factors including the types of plant being grown, the potting mix and the weather conditions. Keep two things in mind – The Big Bag Bed is an aeration container. The porous fabric allows water to evaporate so you may need to water a little more. But, the Big Bag Bed releases heat. It does not get hot like a plastic container, so you may water a little less.
