Gardeners have asked about yellowing cucumbers.
There are some varieties that are yellow skinned not green. For example, Chinese Yellow Cucumber or the heirloom Lemon cucumber. We are not talking about those.
We’re talking about when a green skinned cucumber turns yellow. Most often, this can be attributed to a cucumber that has become over ripe.
Yellowing can also be the result of a nutrient imbalance or virus.
How can you figure out what is up with your plant?
If your plant looks healthy, but the cucumbers are turning yellow, first suspect the most common problem, which is over ripening. A cucumber that is a little bit yellow is all right to eat but the more yellow it is, the more bitter it is and not fit for consumption. You can tell a cucumber is ready to pick when it is firm, green, crisp and generally about 6 inches in length.
If the entire plant doesn’t look healthy suspect a nutrient deficiency.
A couple of weeks ago, I noticed some of our vegetables needed fertilization and recommended using Plant-tone (organic).
If the application of fertilizer didn’t alleviate cucumber yellowing, please let me know. There are viruses that cause yellowing of cucumbers and leaves. Generally it is pretty obvious that something is seriously wrong. If you’re not sure, get in touch. We can figure it out together.
