I don't know what this is called, but those funny cucumbers happen to me too.
I have noticed that are from plants that are infected by aphids or under stress. In the heat of the summer sometime I find cucumbers on a shape of a donuts ... I don't mind them.
I just plant a lot of plants and I am sure some will do that ...
I have transplanted and seeded more cucumbers today (FRUIT DAY).
Well I have more than my share to learn about it but while I was reading most info said it had to do with improper or disturbed pollination processes.
Then the problem becomes I have seen no pollination cucumbers that have that happen also,I didn't know that at the time, so we are still back to why.
Pollination problem. If you only have a few, I wouldn't worry about it. They don't outgrow it but they taste fine anyway.
If you end up with a lot of these, I would pay attention to your bee population and if it's poor, plant some bloomers that attract them and/or consider keeping orchard mason bees. Meanwhile, pollinate by hand if necessary.
Steph, as has been said, it is a pollination problem. Even though there are plenty of pollinators around the blossom may have been damaged in some way. I have this problem when the weather turns hot or when there are spider mites or thrips present. Also I suspect certain plant diseases or viruses may contribute to this condition.
Next year I plan to plant F1's with a good disease resistance package and that are partenocarpic. My very best performers this year were Thunder (slicer) F1 and Corentine (pickle) F1, both from Twilley Seed Company. Although Thunder did get the symptoms exhibited in your photo, it has only been the past week or two after the heat started cranking up.
Yours looks like mine too. I read somewhere where it is uneven watering that causes this. I know that the ones I grow in pots usually look like this where the ones I grow in ground don't unless there is a drought.
Two most common things I have noticed though are "small black bugs" that like the blooms and there is a lot of powdery mildew that occurs here. The bugs are real small ants or long skinny two part segmented beetles also real tiny. they mess up my pollination processes as to my plants.
This is still as said previously "bugs and or stress". Well anyway that is what I have been noticing about why that occurs to mine as to factors. I am finding this thread contemplative as informative.
Stephanie...cukes are not as easy a vegetable to grow as they are made out to be. Like some of the messages indicate if you get past the pollination problem, even watering, bugs (bean beetle, black bugs, etc), mildew and just plain old southern heat you may get a cuke or two. Every year I swear that I'm not planting any more cukes but I usually give in. The best that I grew one year was planted among my herbs basil, chives and parsley and was in morning sun and afternoon shade. Oh yah and don't forget they need mucho nitrogen. Good luck with them but don't let your expectations get too high.
Stephanie,I have Green Finger, Little Leaf, Babylon and Pony doing well. Green Finger gets the funny end every now and then, but most fruit is good. We're hot right now, 90's with no rain for weeks and high wind but these varieties do well.
I have grown Thunder, Marketmore and Ponsett in the past. They were horrible about getting the pinched ends, especially Thunder which is parthenocarpic. I have a lot less trouble in winter than in summer. Little Leaf grew especially well completely under cover (remay, 85% light transmission) and almost no problems at all. The ones grown without cover had more pinched ends.
Little Leaf and Pony are pickling cucumbers, but also delicious fresh.
Muncher and Sweet Marketmore have done the best for me. No heat problems. Of course I don't get Calalily's heat.
Muncher last year tasted great and was steady and reliable. I did get pickle borer last year, but that isn't the cuke's fault. If we don't get rain I drip irrigate once a week or so, but other than that they get no TLC.
All the cuke seeds I sowed March 1 did very well and yes as soon as the weather heated up to the point where the plants needed watering every other day the problem with the curled pointed end began even Thunder and Corentine. Those cukes that were well shaded by leaves seemed to be less prone to the problem. The last dozen or so of Thunder were bitter.
Cukes I sowed later did poor from the get-go.
Early sowing with a shade cloth may be the way to go.
I have got cucumbers coming out my ears! I pickled 6 pint jars and 5 quart jars just from what I picked today! The variety I planted was Cucina hybrid, and they are small, soft-skinned and great tasting. The only bug problem I have had is a very weblike stuff around the plants, but it doesn't seem to do anything to the cucumbers, and it hasn't bothered the leaves either. Might just be spiders. And mine are out in full sun, but they are on a slanted trellis.
Chrissy, I'm in your neck of the woods and am just now watching my plants put on babies. When did you plant and what type? Most of my first batch of picklers gotten chowed by a chicken before they were covered. Those were expensive chicken snacks! Replanted the rest of that row a week later.
Lusciousleaves, I planted Memorial day weekend I planted two regular size cucumber plants and two pickle ones, I'd have to go pull the stakes to see exactly what kind (yep, amateur gardener here!). Let me tell you about expensive chickens, after building the coop, and installing two fences (picket one around my garden and farm fence to keep them away from the neighbors garden) I think we've got the most expensive chickens ever ...and we paid only $8 for the 4 of them originally :-) But they are part of the family.
The eggs and entertainment make it all worthwhile. Plus, they decimated our earwig population within the first year. Pest patrol is another plus. I hear you on the expense getting set up, but as ghg says, it's a one-time deal, except for the recurring expenses of keeping them. We love our winged family members. There hasn't been a guest come to visit than hasn't fallen in love with them as well.
GHG, my pickles are always soft. I hear if you use pickling lime, that keeps them crunchy. I don't make dills here, just bread and butter and sweet relish. Keeps the soft from being an issue.
Back to the cukes, and thanks for answering Chrissy. :)
So, we love all our pets (Dog, 2 cats, 4 chickens and many fish), they are all very spoiled and well worthy any expense (even though I whine about it once in a while) And you're right, in addition to producing eggs,those chickens provide hours of entertainment! I grew up in the northern suburbs of Chicago, my husband is from Milwaukee; So most of our friends and family think I'm crazy for having chickens, those city folk just don't get it until they come to visit and see the girls in action :-)
Aren't you glad it finally cooled off enough to actually go outside? I really need to get some weeding done this morning seems the weeds don't really need water to grow.
