What makes vegetable garden leaves turn yellow?

Question

My cucumber and squash plants in my vegetable garden has leaves that look too yellow. Does this mean I am watering them too much by watering them almost everyday? Or is it a mineral problem?
I want the leaves to look nice and green instead of yellowish like they are.
Thank you,

Too much water can dilute the mineral content in the soil.
In this case, what's turning it yellow could be one of two things: the lack of nitrogen in the soil (be it caused by repeated gardening and lack of replacement....or overwatering), and since you live in Florida, I know it's warm enough that you have probably have blossoms already: it could also be squash beetles. They bore into the center of the plant, via the blossom, and then the nutrients don't circulate, etc...etc...etc...
So: check the plant for beetles. You'll be able to actually see them in the middle of the blossom. Pluck them out as they DO definatly offend. If the hole can repair itself, the plant may live. Now...if you DO have this beetle, also be on the lookout for wilt....where there is a squash beetle, there are millions of dirty little feet, wandering across leaves, trapsing through mildew and wet leaves, from plant to plant, sharing the un-lovely things that make leaves go YUCK in the night....(especially humid nights like those in FLA)
DONT water everyday, and restore the nitrogen. Organic replacement through application of compost tea is my favorite, but....if you don't have a heap already (start one!!) and go get a good (preferably organic) nitrogen rich application/fertilizer.

Good luck and happy gardening!

Answer 5

everyday watering could be too much, but my guess is that there is not enough mineral content (fertilizer ) in soil. I am a confirmed organic gardener and when I plant ANYTHING, I always put oul vegetable scraps and eggshells and any other organic material right in with the seed. As it breaks down, it then feeds the plant. Of course you can also buy organic fertilizers, and you can also buy soil testers that let you know what minerals are needed for your soil to make it the best. After all that is what you want for good harvest.

Answer 6

they are yellowed from lack of iron.. this could be a ph problem so test your soil.. there are low cost ph test at most garden shops.. also there is a product that adds chelited iron to the soil also available at most garden shops.
