Great Advice Dave. If I may add a couple of things I have found useful. First it is a waste of time using a watering can on dry soil, as one 2 ltr water can just waters the top half inch of soil causing roots to come up, which makes matter worse. If any of my pots dry out, I find it better to dunk pots up to their brim to dispel air. Hold them under the water until the bubbles stop. Hoe the ground often to break it up so when it rains the water will soak in and not run off. Water retaining gel in pots and baskets certainly help, and one final tip. Put a couple of ice cubes in the top of the pot or basket to melt slowly.
