Cucumber plants are particularly sensitive to temperature extremes. Temperatures below 50°F (10°C) can slow their growth, harm them, or even kill them. On the flip side, temperatures consistently above 90°F (32°C) during the day can stress plants, potentially leading to poor fruit development or dropping flowers. Optimal daytime temperatures range from 70°F to 85°F (21°C to 29°C) with nighttime temperatures ideally above 60°F (15°C). Monitoring and adjusting your garden practices during extreme temperatures can protect and maximize your cucumber plant's productivity.
