Cucumber Fruit Yellow on the Vine: Overripe Fruit and Picking Times
Cucumber fruit yellow on the vine is most often fruit left too long. Extension guides agree that cucumbers are picked young before the seeds harden.
The short answer
Oregon State notes that over mature cucumbers often turn yellow orange or white. Pick slicing types at 6 to 10 inches and pickling types at 2.5 to 6 inches. Check vines every other day. Illinois Extension says to pull missed fruits so young ones go on forming.
Why do cucumbers turn yellow on the vine?
South Dakota State says very ripe cucumbers turn deep yellow with spongy flesh and hard seeds. Overlong fruit pulls the plant away from new fruit. Oregon State says to harvest before fruit turns yellow and the seeds harden.
Pull any missed fruit since it slows new fruit.
What size should cucumbers be picked?
Oregon State lists 6 to 10 inches for slicing types and 2.5 to 6 inches for pickling. South Dakota State says most pickling types make firm dill pickles at about four inches. Illinois Extension lists 2 inches for pickles and 4 to 6 inches for dills.

Can other problems cause yellow fruit?
Oregon State notes that some quality cucumbers are white or yellow by type. Read the seed packet before calling a yellow fruit overripe. Iowa State and South Dakota State both advise frequent picking because summer fruit grows fast.
Pick at least every other day in summer.
Troubleshooting
Deep yellow with hard seeds: fruit is overripe. Pick sooner and more often.
Vine stops setting fruit: a mature fruit remains. Pick it.
Bitter fruit: plant stress from heat or cold or drought. Oregon State says peeling lowers the bitter taste.
