Why Are My Cucumbers Turning Yellow

If you have cucumber plants in your garden and you are wondering why they are turning yellow. You might want to take a look at this guide.

A couple of factors such as over-ripeness, pollination problems, water inconsistency, or even a virus can cause your cucumbers to turn yellow.

We will be discussing more on why your cucumbers may be turning yellow. We will also discuss what you can do to achieve a green healthy cucumber.

Reasons Why Your Cucumbers are Turning Yellow

It can be pretty disappointing when your cucumbers turn yellow, orange, and ugly. When this happens, you should throw them away because they are bitter and not healthy for consumption.

Below are some of the reasons why your cucumbers are turning yellow:

Pollination Issues: Unsuccessful pollination can cause your cucumbers to turn yellow. Usually, the female flower bears a small cucumber-like fruit with a flower at the top.

Note that this is just the female flower with an ovary at the bottom and not a growing cucumber. This female flower will need to be pollinated by the male flower (pollen grains) which is also on the same line with the female flower. When successfully pollinated by the male flower, the ovary will begin to grow and become a cucumber. But if pollination fails to occur, the female flower will wither away and the cucumber-like ovary will turn yellow and fall off.

Water Inconsistency: Cucumber plants do love water. But when there is too much water in your cucumber plants, it can cause your cucumbers to grow fast, turn yellow and create mildew.

Mosaic Virus: The mosaic virus can cause your cucumber fruits to turn yellow and taste bitter.

Over-ripeness: Cucumbers grow very rapidly. It is important for you to always keep a close watch on your cucumber plants. Pick your cucumbers when they are due and don’t leave them too long on the vine as they may turn yellow.

Bacteria and Fungi Issues: Bacteria and fungi issues can cause yellow cucumbers and leave your plants wilted. Choosing resistant varieties is a good solution.

Solutions to Growing a Healthy Cucumbers

Ideally, when you grow healthy cucumbers, they should be green and about 6 to 12 inches long.

Below are some solutions to the problem we listed above:

Pollination: Pollination issues can be solved by hand pollinating. Identify the male and female flowers on your plant. Pick the male flower and put the pollen grains in the middle female flower. Simple as that. For better clarity check out the video below.

Watering: When it comes to watering your cucumber plants, you want to water moderately. Cucumber plants should be watered often but not too much.

Virus: The appropriate solution to the mosaic virus is to eliminate and destroy any plants that are exhibiting signs of the virus. You should also monitor the rest of the cucumber plants in your garden and act fast when they develop any symptoms of the virus. There are also some mosaic-resistant cucumber varieties. So we suggest you go for these varieties when picking the type of cucumbers to plant.
