Which management practice can enhance plant health?

Providing adequate sunlight and air circulation is essential for enhancing plant health because plants depend on light for photosynthesis, which is the process through which they convert sunlight into energy. Adequate sunlight promotes vigorous growth, flowering, and overall vitality. Additionally, proper air circulation helps to reduce humidity around the plant, minimizing the risk of fungal diseases and pest infestations, which can thrive in stagnant air. This practice also encourages transpiration, allowing for better nutrient uptake from the roots.

Options that involve overwatering, relying solely on chemical fertilizers, or ignoring pest signs can lead to adverse effects on plant health. Overwatering can cause root rot and encourage the growth of harmful pathogens. Solely using chemical fertilizers may lead to nutrient imbalances and neglect the benefits of organic matter and natural soil amendments. Lastly, ignoring pest signs can result in unchecked infestations that can severely damage plants. Therefore, providing adequate sunlight and air circulation is the most effective management practice for promoting plant health.
