Cucumber and zucchini leaves yellowing and wilting #341278
Asked July 09, 2016, 11:35 PM EDT
What could be causing the leaves on my zucchini and cucumber plant leaves to yellow, wilt and eventually shrivel and turn brown? Today I pulled off shriveled brown leaves that were yellow yesterday. Now more leaves are turning yellow and the whole plants are green-yellow, rather than deep green, like the zucchini & cucumbers I have in another bed. We were wondering if it could be overwatering, too much sun (6-9 hours), some kind of insect? Thank you for your help!

I would liquid feed them.
Meanwhile, do a soil test to ensure the pH is at the proper level.

We recommend Univ of Deleware as the best choice, on the list, for testing vegetable gardens because they will test for lead. Lead is a chemical of concern in a veggie garden.
If your garden is new soil than it might be a lime problem.
Not matter the plants look fertilizer deficient. Over watering could cause similar conditions but you would have to work hard to over water a raised bed of your nicely textured soil.
Liquid plant fertilizer is equal to the intravaneous feeding they give people arriving at the hospital emergency room. If you pour it over the plant foliage it will be immediately absorbed!
If your plants look different after performing this two consecutive days then you will know it is a nutrient deficiency. Follow the directions on the plant food of your choice, using the dilute solution listed on the label.
A soil test will take a few weeks and that will tell you what to do next.
