They are not completely yellow but some are partly yellow. My garden is healthy but just the cucumbers are turning yellow.

Answer 1

That one is just over mature. If this is supposed to be a large cucumber variety then you may be lacking phosphorus and potassium in your soil. Lacking these will lead to small fruit, and if you leave it on expecting it to grow, then it will just go over ripe.

Make sure to add compost, or a high phosphorus and potassium mix as a top dress, as well as dolomitic lime, and you will likely see a very fast improvement.
