Cloudy weather and rainy days can impact plant growth. Low temperatures can lead to establishment issues and unusually cloudy or rainy conditions can change the look of the plant - plants may produce bigger leaves in response to generally low radiation. Root development can also be affected, as root systems do not need to seek out moisture at…
