Is there any information about thinning (pruning)landscape plants, to reduce transpiration, in order to conserve water? Wouldn't reducing the size of plants reduce the amount of water required to keep them alive?

Hi John,  
Pruning recommendations for landscape ornamentals is typically species specific. Often, cutting back a woody perennial can push new lateral growth on a plant. Because of this response, it is better to consider other drought gardening practices such as avoiding fertilizer, mulching generously and watering deeply.  
Best, Melissa
