In greenhouse cucumber cultivation, proper canopy management is essential for optimal growth. By evenly distributing the leaves, the plants can make the most of available light, ensuring balanced development and higher yields. This technique also helps maintain an efficient light exposure pattern, promoting healthier and more vigorous growth.
For disease prevention, it's important to promptly remove diseased or old leaves and burn them outside the greenhouse. Additionally, avoid watering for at least seven days before pruning. This practice helps lower the moisture content in the vine tissues, increasing their flexibility and reducing the risk of damage during handling.
To prevent vine damage, monitor the growth points near the roof and ensure that the base of the plant remains free of unnecessary leaves. If the vines spread more than 30 cm from the ground, they should be pruned or redirected promptly. When harvesting, it's best to pick the fruit in the late afternoon when the vines are less tender and less likely to be damaged. Avoid picking in the morning or right after watering, as the high water content makes the vines more fragile.
In a leafless greenhouse setup, the leafy vines should be kept at least 13 cm away from the ridge surface. Each plant should maintain a minimum of 20 functional leaves to support healthy photosynthesis and overall plant vigor.
When training the vines, use a lanyard system to gently wrap the stems rather than pulling them forcefully. Avoid twisting or bending the vines in the opposite direction, as this can cause cracks or breakage. Instead, guide the vines along their natural growth direction to promote strong, stable development. These careful practices contribute to a more resilient and productive cucumber crop.
