Wow! Thank you everyone for the kind and detailed responses. I truly appreciate them
Lindsaylew82, thank you for the welcome!! I will upload a photo as soon as I can to show you guys. The newest cuke, the lemon variety, is all by himself in a big pot with special soil (not my own) to see if that makes a difference. He is not dying 100% yet, but his yellowing of the leaves concern me and just the wilt as a whole also concerns me. The other 4 that I have in my big garden have died. I water him twice a day. I cut into one of the leaves to see if there was any bacteria coming out (read about that online) and nothing but clear liquid oozed out of it. There are no bugs that I'm able to see on it or near it.
imafan26, thank you very much for your detailed response, too! I am thinking that maybe there's a cuke apocalypse going on right now and I shouldn't be planting them in NY. Hence why I tried planting him in his own pot with plenty of room and sunshine to see if there was a problem with my ph in my soil or anything else that could possibly be draining his energy source. I've done my research on which varieties are best for resistance, etc., also, so that I'm covering all of my bases. I've never had a problem in NY before... Considering I am growing this one in his own pot now with pre-bagged soil, my gut is leaning to a disease or some sort of pest. I am planning on doing my own ph test as well (thank you for suggestion!) to see what's going on. I have all sorts of beautiful tomato, squash, kale, and zucchini plants that are big and huge - they seem to love the soil. But alas, I know that not all plants like the same soil. I do not use a lot of chicken manure. Only a few pebbles for every plant when they are first planted into the soil.
AnnaIkona, yes I did my research on that, too - trust me! I am a pro gardener
I only put a few pebbles of granulated, homemade chicken fertilizer with each plant that I actually plant into the ground. I don't add them to the seedlings. All of my other plants thrive on the homemade fert, but it just may be that it's burning up the cuke - which could make total sense. It's just never been an issue for me, so I feel like I'm trying to gain any information I can. Thank you for your help
jal_ut, absolutely about the water. It's a pretty obvious answer - BUT, I don't want to overwater. I know you can also kill plants that way. These are my babies, so I treat them as my children! I keep it very minute with the fert and anything else I may do (which is not much because I'm an organic farmer/gardener) thank you!
I may do some fish emulsion watering and see if that helps, too. Perhaps he's thirsty for some vitamins. Thank you all so much for your help!
