Water for sure! How dumb to go to all the work and expense of preparing a garden, starting seeds or buying plants, planting... and then let things shrivel and dry up unnecessarily. Where I live I could probably get away with never watering most years, but the plants have enough issues with our short growing seasons... I have rain barrels, and if need be will use tap water.
My house plants, however, have become accustomed to living through long periods of drought and neglect
