Seeing your vegetables grow poorly is something EVERY plant grower fear. Are your cucumbers yellow, or if cucumbers turn yellow, there are signs that you need to consider. We’ll help you nurture your cucumber plant back to health!

Variety of Cucumber

Let’s get to the first test. Yellowing cucumbers? Well, your green cucumbers might actually be yellow or lemon cucumbers. There are MANY yellow cucumber varieties! You might have gotten the WRONG seeds that produce yellow cucumbers.

Sure, plants love water but don’t go overboard. Cucumber plants DON’T like to be drained in the water ALL the time. Give their roots time to BREATHE, or your cucumber plants will turn yellow. 

How does one do that? Well, make sure that your garden soil drains properly. If the soil drainage isn’t proper, your plant’s roots will have stayed in the water for TOO long. This can rot the roots from the inside out. How would you feel if you had wet feet? 

Poor Pollination

Your cucumbers are turning yellow because of a lack of pollination. It’s an issue If the plant’s female flowers aren’t receiving enough visits from bees. Or if the female flower doesn’t produce enough nectar, there is a reduced flow of necessary nutrients

So if you want to grow greener cucumbers, keep track of those plant flowers. If pollination isn’t happening correctly, the flower and the tiny fruit beneath it will fall off. 

The fruit doesn’t bear the entire genetic code since the pollination isn’t carried out properly. This affects the overall quality of your fruits. It might be a reason why your cucumbers are yellow. This is a simple test-it-yourself situation; there is no need to get a soil test. 


What all green thumb people DREAD is a plant disease. Diseases like downy and powdery mildew can be the causes of your yellow cucumbers. These plant diseases infect the plant’s leaves, stems, and fruit. 

They can spread, especially where soil moisture levels are high (they’re a fungal disease). . Make sure you monitor your plants regularly for any condition. Here is a list to look out for:
