Why are my cucumbers not maturing properly?

Cucumbers may not be maturing properly due to factors such as inadequate sunlight, inconsistent watering, lack of nutrients in the soil, or pests/diseases affecting the plants. It is important to ensure that the cucumbers are receiving sufficient sunlight, consistent watering, and proper nutrients to promote healthy growth and maturation. Additionally, monitoring for pests and diseases and taking appropriate measures to address them can help improve the health and maturity of the cucumbers.
