The leaves are turning yellow and dying afterwards. How do I stop this? They are planted in pots. Could it be from too much water?
Yellowing leaves can indicate watering issues; too much or too little.
Make sure the soil is well draining and that excess water can drain from the container.

My plants are growing all over and now into the driveway. If I cut the lead edge will that harm the plant or just stop the growth?
You can locate the main stem of the plant and remove any side shoots that are growing from this main vine.
Remove the first 4 to 6 shoots growing closest to the base of the plant and leave all the rest.
Plants grow quickly, so you may have to do this more then once.
I also may suggest putting up a temporary fence or trellis to gently place the cucumber vines on.

For future planting, I would suggest growing a 'Bush Cucumber'. I have raised beds and this type of plant stays much more contained and still produces lots of cucumbers.
My cukes never turned green..just yellow. I planted pumpkin right next to. Could this be why they're not green? Or maybe not ripened yet? I only watered once a day but we did get a lot of rain for awhile. They seem to be growing really great just all of them never got green at all.
Since you mention heavy rain, I suspect a watering issue. Your container or soil may not be draining either fast enough. This can lead to yellowing of leaves and rotting of the fruit.

Hello! My cucmbers have been thriving all summer and have finally started to bare fruit (yay!). Yesterday all of a sudden I've noticed most of the bottom leaves and a few higher up have just gone and wilted, and have started to die. Most of the online sources I've come across assume bacterial wilt to be the primary cause of sudden leaf wilt, however, I've seen no evidence of a nasty little cucumber beetle and when I do the bacterial wilt test of cutting a wilted leaf near its base to check for sticky string fluid, there is none (leaf and stem seem to be normal except for the wilt). It's been average summer temperatures lately, with a few overcast/rainy days, but watering has been fairly normal. I have both the pickling and lemon cucumber variety, and the lemon variety seems to be affected more. Some spotting noticed on some of the upper leaves.. unrelated? Any suggestions?
Some wilt on the leaves can be common during the heat of the day. Plants recover in the evening when they cool down.
Make sure the soil is evenly moist, and that it is well draining.
If you see no signs of pests or markings on the leaves, I would not suspect disease.

I have powdery mildew on my cucumber plants. I sprayed them with a solution of 9 parts water to one part hydrogen peroxide. I have removed most of the badly damaged leaves. How do I know if it is working? Will the mildew disappear? One source says to spray daily and another says weekly...which is it? Thanks for any help.
There are several websites that discuss using hydrogen peroxide as a cure for powdery mildew on cucumbers. I am hesitant about using the milk remedy because I wonder if it will leave the smell of milk or possibly spoiled milk around my balcony garden. Plus apparently there are many benefits to using hydrogen peroxide in a garden. Thank you for the info.
Sorry, I forgot to include the link; http://www.veggiegardener.com/preventing-powdery-mildew-on-cucumbers-squash-melons/
TIL: hydrogen peroxide for mildew. I don't see how it can work. You are dealing with a fungus. Most homemade remedies include baking soda or milk. If the plant it badly infected, throw it in the trash, not the compost. Here is a link to one source that discusses how to prevent powdery mildew in cukes and gives homemade recipes. I don't know if there is any scientific basis for them or any study proving efficacy. (Actually, I doubt that there is but it's worth a try.)
This year my cukes are out of control to the point where we have built 3 extra trellises for them. I have noticed quite a few that are coming in looking like zucchini on the tops and a cucumber mid-way down. Hence "zu-cumber." Why is this happening and is it still possible to eat? If so, when do I know it's ready to pick?
Cucumber and Zucchini cannot cross pollinate because they are 2 different species. Check the variety that are growing this year and compare the characteristics of the fruit.
In the meantime, enjoy the bumper crop!
