Effects of Watering
Plants
Over Watering
•
•
•
•
•
Shallow root systems
Root rot
Wilting
Nutrient deficiencies
Stunted growth
Under Watering
• Decreased Growth
• Decreased rate of
photosynthesis
• Smaller leaves
• Shorter internodes
• Stunted, hardened
appearance
How to Determine When
Plants Need Watered
• Learn plant signal.
• Watch for drought
stress.
• Discoloration of the
plant.
• Lack of turgidity in
the plant or turf.
• Wetness of the soil.
