What are common causes of most plant problems?

Plant problems often stem from environmental conditions, nutrient deficiencies, and injuries. Environmental conditions include factors like temperature fluctuations, humidity levels, and sunlight exposure, all of which can negatively impact plant health and development. For instance, excessive heat or cold can cause stress to plants, leading to stunted growth or even death.

Nutrient deficiencies arise when plants do not receive the essential elements they need to thrive, such as nitrogen, phosphorus, or potassium. This can result in symptoms like yellowing leaves or poor fruit production.

Injuries, whether from mechanical damage, animal feeding, or even herbicide exposure, can weaken a plant, making it more susceptible to disease and pest infestations. Understanding these common causes is crucial for effective plant management and to prevent and address issues as they arise.

The other options address different aspects of plant health but do not encapsulate the broader and more critical issues of environmental stress, nutrient needs, and physical harm that frequently lead to plant problems.
