What To Do When Cucumber Plants Yellow

Posted on Oct 14 2009 - 5:00am by Mike Lieberman

I’m still figuring out what to do with my cucumber plants because the leaves are yellowing.

It’s just over a month since I moved my cucumber plant across the yard. The plant was moved for a few reasons. First being that it was outgrowing the trellis that I built for it and needed more support, so I moved it close to the fence to train it up. The second being that the leaves were yellowing, which I thought was due to sun exposure.

The plant is growing along the fence, still bearing fruit and blooming. That’s nice, but the leaves are still yellowing. My next guess is that it’s due to the lack of nutrients, so I threw some left over compost that I had in the container.

The important part is that the plant is still producing because I’m about functionality first and aesthetics second. My guess is that the yellow leaves can’t be good for the long term health of the plant though, so I’d like to remedy that.

What’s your thoughts on what to do when cucumber plants yellow?

    My experience has been that yellowing leaves mean an over-watered plant. I know you're using self-watering containers. Check the drainage situation.

  • Mike Lieberman

    They are draining. Maybe I have too large of a water reservoir? Thanks.

    Hi Mike! Great work…keep it up! You have officially inspired me to get back out there and get my beds ready for some winter greens! THANK YOU!
    How's your aeration? I found my big viney's like cuke, zucc and pumpkin like a big pile of sticks and dirt that add air and hold in warmth for me to get a good yield. So maybe temperature as well? I did have good luck with zucchini in pots on the roof to keep the roots warm last year.
    It's also time for me to restart my indoor hydroponic greens garden with new design enhancements….cross your fingers everyone, should it rival the last one I'll post my plans. Grow on Mike!

  • Mike Lieberman

    Awesome Damon. Glad to hear that. It's interesting, everyone has their own thoughts as to what it could be. As long as the cukes are growing, I'm happy.

    Definitely keep me updated on your projects. Fingers are crossed.

    Try some epsom salts. I use it when my tomato leaves go yellowy.  The e.s. works to increase chlorophyll production and helps the plant suck up and use soil nutrients such as nitrogen.

And you really don’t believe  it, that I have really found the best quality cucumber from this method. And this one is really one of the extreme way for getting quality cucumber. Thanks for sharing some magnificent information about it.

    Thanks for the comment Martin. There really has to be a better way for you to get a link back to your site then to squeeze links into your comments. It has been edited.

    One year I used chicken manure from my neighbor’s farm in the garden ; was terrible for all the plants except the the cukes which flourished!

    Was the chicken manured composted and completely dried out. Heard chicken manure is supposed to be great.

    Seaweed solution is always a good tonic when things look unwell, I’d try epsom salts too.

    Good call. Thanks!

    We grow lots of circubits including cucumbers using only fish emulsion and compost tea for fertilozer.

    Nice!

  • @tropicalbloom

    If its the mature or lower leaves that are yellow I would try the epsom salt. If not I would try compost tea in a foliar application so the plant can recover faster from what appears to be a nutrient deficiency.

    Thanks for the info.

    did you ever find a solution to work? I am running into this with my cucumber plant now…

    I’ve had the same issue with my cucumbers. Everything around it is doing excellent, but this past week my cucumber plants went from medium green to light green with yellow and brown spots. Needless to say I was scared. I researched everything and finally settled on making a compost tea ( organic compost with water) and adding diluted urine. I did that the last two days ( I just poured it around the base of the plant). I also stopped watering them overhead with my sprinkler nozzle. I actually took the nozzle off and just gently water the bases. It seems to definitely be working. I still have leaves ( lower ones) that have yellow spots, but the leaves are becoming a darker green finally. The top leaves are dark green. I also have flowers budding, so I think it’s doing better. The plants are also growing taller everyday! By the way, my compost isn’t very strong it only has 1% nitrogen, phosphorous, and potassium. I’ll probably add a little diluted urine over the next few days to make sure that it’s truly better. I also figured out that my cucumber plants are way to close together ( like 1-2 inches), which may be the problem also. I’m going to definitely look for a stronger organic compost for next year. This is my first garden, and I so love it.
