Cold water from a hose: shock for roots

Cucumbers are native to the tropics - their roots cannot tolerate temperatures below +18°C.

Watering with ice water causes stress and provokes powdery mildew.

A study by Wageningen University (Netherlands) confirmed that when watered with cold water, crop yields drop by 60%.

"I watered from a well - the cucumbers were covered with a white coating. I switched to settled water - and collected three buckets!" - writes Olga from the Tula region on the forum "Cucumber Paradise".

Daytime watering: sunburn

Water droplets on leaves turn into lenses in the sun, causing burns.

Urban Farmer magazine called this the "magnifying glass effect."

"I watered it in the morning - the leaves became full of holes. Now I only water it at the roots in the evening!" - Anastasia from the Moscow region shares on Instagram.

Overwatering: Swamp Syndrome

Cucumbers love moisture, but stagnant water leads to root rot. Humidity sensors installed by agronomists from Israel showed that when overwatered, the roots begin to die off on the 3rd day.

"I watered the bed - the cucumbers rotted in a week. Now I water it once every 2 days and only if the soil is dry!" - Igor from Voronezh admits on the YouTube channel "Dachny Detective".

Hard Water: The Killer White Limescale

Lime water clogs plant blood vessels and blocks the absorption of nutrients.

Water treatment expert Elena Kristalnaya writes in an article for Gardenia :

"Water hardness above 8 dH is a death sentence for cucumbers."

“I add 1 teaspoon of citric acid per 10 liters to the watering can — and the cucumbers come to life!” advises Valentina from Rostov in the comments.

Conclusion

"Cucumbers are not cacti, but they are not algae either. If you are still pouring ice water on them, stop! After just 5 days of proper watering, they will start to come back to life.
