I have two plants this year... Have had multiple fruit seem to pollinate then when basketball size or larger the blossom end turns white and fruit rots... I have grown in this patch 3 years... last years kins went 20% light to chart (so my eyebrows went up) any thoughts? I have been spraying some calcium (once so far) that I have for tomatoe blossom end rot

Soil or Tissue test. I am in the same boat. I have been growing 18 years and cant diagnose my own issue, which frustrates the crap out of me

Are you having issues with plants also

I had that in 2011 with one of my plants. Every fruit did that. I pulled the plant and never planted that seed again. I figured it was an issue with my seeds. possibly some sort of disease in the seed.

I have the same problem. My plant looks great but I did note some browning on some short sections of the vine. It is not a bug issue. second year now if I take a tissue sample from where is the best place to take it and where do I send it? Thanks for any help. Chuck

Plant stress of some sort will cause aborts, to wet to dry or disease. If you pull the plants look at bottoms of vines, around the root areas slice them open to see if you can find anything out of the ordinary. If it's been real wet look for fungas gnat grubs on the under side of vines or even in them. Orange discoloration inside vines may be caused by fusarium.

Thanks Baitman, rick I'm just frustrated ...just like linus I've been growing for years and seen a lot of stuff but this one I have no clue. I'm hoping that Baitman's picture will work for diseases too. as al berard sez wait till next year!

I have had several plants that eventually abort or grow deformed stunted fruit. No matter what you do, they won't grow right.
A 1290 Poirier did that to me and a 778 Howard back in 07. I have always thought it was a genetic issue.

It is a little suspicious though, that you have two plants and both are doing it. If they are from different seeds I would be more baffled, and wonder if it is in the soil or something you are doing culturally.
I believe You said both plants are from the same seed? If so my guess would be genetics of that seed.

Actually both plants different seed (same as last year s) I am worried about my "cultural practices"... but I'm pretty unsophisticated grower... no daily spray but once a week pest (bifen) ... I did start using some urea mate last year in drench (2 oz in 100 gal) every couple days ... not much more after spring soil amendments... I am a pond waterer , that has me wondering too ( but plants look good)... the final note is that I do have a third plant that gets no attn. (yard ornaments for grdkids) and it has 3 healthy fruit! It gets nothing but occasional water.

I have had 14 aborts on my 1 plant now. The weather has been perfect for the most part, and 3 of 4 remaining just went down by 7 DAP. I have 1 last 12 DAPer going and it is getting more wrinkled daily and barely growing. It is 100% on the plant. There are 2 varieties of other pumpkins growing next to the huge AG plant and they have 12 pkns going strong, so it isn't a condition in the soil or any type of plant stress. The plant is in perfect condition.

Sometimes I think these plants can sense that they are important to us. Those are the plants that always give us problems. The plants we ignore and don't worry about, do just fine on there own. It can be a very frustrating hobby.
