Do I need to water everything in the garden all year round?

In the drier seasons, spring and summer; if water conservation is an issue, concentrate on watering anything newly planted that year – these plants should take priority over anything already established in the garden that will be better at taking care of itself. Of course during hot, dry periods it would be ideal to ensure everything other than the most drought tolerant, is kept watered. During wetter seasons the watering often takes care of itself – although make sure you do not take this for granted – keep an eye on the frequency of rain!
