While the greenhouse industry offers controlled environments for year-round cultivation, it comes with unique challenges, or growing issues. Water and nutrient management, pest control, stress factors, and facility shortfalls require careful attention and proactive solutions.

Water Management: Striking the Right Balance

Each plant species has unique water requirements that vary based on light exposure and seasonal changes. Overwatering can lead to root rot, while underwatering can result in slow growth, leaf damage, or even plant death. It’s essential for growers to tailor their watering practices to the specific needs of each crop, adjusting for changing environmental conditions. Remember, the amount of light in the day directly affects the amount of water your plants need. Lantana may require lots of water on a sunny day in the summer, but the water needs will decrease as the days grow shorter and colder.

Balancing Nutrients for Optimal Growth

Nutrient management is a delicate dance, with different crops, ages, and seasons requiring different rates. Too much fertilizer can lead to root rot, while too little can stunt growth or cause leaf damage. The challenge intensifies during hotter times of the year when plants need more water but experience slower growth. Young plants have different nutritional needs than mature ones, demanding a nuanced approach to maintain a healthy nutrient balance throughout the growth cycle.

Pests Cause Growing Issues

Pests are a persistent threat in the greenhouse, and different plants attract different pests. Some pests can be outright detrimental, while others may only pose a nuisance. Controlling pests becomes increasingly challenging once they establish themselves. Read our blog about an integrated pest management system here! Successful pest management involves understanding the specific pests affecting your crops and implementing targeted control measures. Different crops may require different approaches, making it crucial for growers to stay informed about the latest pest control options. Eliminating pests will eliminate a lot of growing issues.

Stress Factors: A Multifaceted Challenge

Plants in the greenhouse can experience various stress factors, including water and nutrient stress, environmental factors such as light, temperature, and humidity fluctuations, pest infestations, and the challenges of transplanting and transportation. Stressed plants exhibit slower growth, requiring careful adjustments to fertilization and water levels. Maintaining optimal growing conditions and promptly addressing stress factors are essential for ensuring healthy, robust crops.

Facility Shortfalls: Addressing Infrastructure Challenges

Greenhouse facilities are not immune to challenges, and addressing facility shortfalls is critical for sustained success. Issues such as heaters leaking ethylene, overcrowding of plants, inefficient production lines, and poor techniques by employees can all impact the overall health and productivity of crops. Regular maintenance, employee training, and investment in up-to-date equipment are essential steps to mitigate these challenges and optimize greenhouse operations.


By staying informed, implementing best practices, and adapting to the specific needs of each crop, greenhouse growers can overcome these challenges and cultivate thriving, healthy plants.
