Gardners & Farmers: What's Causing My Plants to Die?

[OTPTT]

I've tried to find some Neem Oil and finally found a nearby farm and garden supply store that sells it but it will be in later this week.

Now here is what I'm seeing in my garden. I can't tell whether it's to much or to little watering of the plants. I know that if I water the squash to much the leaves will turn yellow. However, I'm having a problem with my cucumber plants as you can see in the following images.

I'm thinking that cucumbers require more watering than do the squash plants but I don't know if it's a watering issue or not.

Some of the leaves will start to turn gray and appear fuzzy in texture then they begin to die as seen below. The leaf at the top is in the earlier stages of the process and the leaf toward the bottom that's brown is in the latter stages. Otherwise the plant is in good condition.

Same cucumber plant above but one of the cucumbers shriveled up and is apparently dying as seen below. There are other flowering cucumbers that haven't shriveled and died and I'm hoping to prevent this if at all possible.

Here is the same plant in the above two images where the leaves are turning yellow and dying. Again I'm thinking that maybe this is a watering problem. Any ideas as to what might be causing my plants to yellow and die?

I'm going to find a free online pdf file relating to the proper care of vegetables and fruits. Maybe someone knows of such a resource?

Thanks SSanguine. Could be bugs. Will do some more research.

caveat emptor as far as my advice goes since i have limited experience, but a few things jump out.

One is the pot you have the cukes in is barely big enough for the root system of one, let alone three like you have. you should remove all but the healthiest one, otherwise they will be weak and susceptible to disease, especially root rot (so make sure at all costs they have some days where the roots are dry - you probably don't need to water them at all since it's a wet, mild summer; last thing you want to do is over-water them). then I would recommend taking it out of the pot and putting it into the ground.

make sure they are getting enough sun, it looks kinda shady where you have them. it's been a wet summer, so fungi are running rampant. neem oil is more for pests.
