They are enthusiastic, willing to learn and to help others, and able to communicate with diverse groups of people. What really sets Master Gardeners apart from other home gardeners is their special training in horticulture. In exchange for their training, persons who

This article also covers:
• Signs of heat stress
• Deep watering recommendations
• Mulching tips
• Caring for young vs. established trees
