- Stem rot at the soil line.
Solution
- Plant seedlings at the correct depth.
- Ensure the root ball is level with the soil surface.
Transplant Shock
Symptoms

- Slow growth.
Solution
- Harden off seedlings before transplanting.
- Water thoroughly after transplanting and provide shade if needed.
7. Chemical Damage
Herbicide Drift
Symptoms

- Yellowing or browning of foliage.
Solution
- Avoid using herbicides near cucumber plants.
- Rinse plants with water if drift occurs.
Over-Fertilization
