What happens if I fertilize my Cucumber too much?

Over-fertilizing Cucumber can lead to root burn and even the death of the entire plant in extreme cases. More often, the plant will develop a lot of lush green foliage, but the flowering and fruiting will be reduced. With more leaves, there is also the danger of inviting more pests that feed on your Cucumber. It is possible to over-fertilize with both natural fertilizers or chemical fertilizers, although the latter is more common. Nitrogen is the most likely to cause problems but any nutrient in excess will cause similar problems. When using multiple types of fertilizer of soil amendment, make sure you understand everything that they will be introducing to your soil. If you add several different soil amendments that all contain the same nutrient, you could overdo it before you realize what has happened. Finally, it is important to avoid applying too much fertilizer as it can pollute groundwater. Unused nitrogen is not absorbed into the soil, so it can drain into nearby water sources and cause high concentrations of nitrates. High levels of nitrogen-nitrate are unhealthy for human and animal consumption, so it is very important to only use as much fertilizer as plants need.
