Zucchini blossom-end rot

naemsmommy on Mon 5 Jul - 14:15

Hi there,

My zucchini grow nicely at first, but then some of them develop blossom-end rot and shrivel up and turn yellow on the ends. I read to apply dolomite lime to the plant, but I just read somewhere else not to apply dolomite lime to growing crops because it needs to be applied several months prior to planting. Now I'm not sure what to do?

Also, if it is ok to apply it, should I apply it to my whole garden, or only my zucchini plant?

Thanks!

I have the same problem, so I am hoping someone answers

How big do they get before they shrivel up? If they don't get all that big, could it be a pollination problem? I ask because I thought I had blossom end rot one year and it turned out to be a pollination problem. Once I started hand pollinating they stopped shrivelling up.

Just thought I'd throw that out there since I'd confused the two in the past.

Some of them get quite big before they shrivel, and others shrivel when they are still small, so I'm not sure. I was thinking of hand pollinating just to be sure. When do you do it?

I do it as early as I can get out there in the morning. I find that if I don't get out there until after 9am or so they have closed back up. It's worth a shot.

OK, I will try that, thanks!

I had trouble with that too at first... lost maybe 5-7 smallish squash to it. I gave the rampicante some smashed-up Tums and have not seen any more BER since. (Well, maybe once, but something was also munching on that one.) I just put down some more yesterday, just in case.

Yeah I have already fed them and dosed w/ powdered milk. The problem continues. It makes me sad, I loves the summer zucchini.

Aw, that is so sad.... Sad

I wish I could help. I had to tear out my yellow crookneck.

I am having the same problem this year. I usually have a ton of zucchini by now but so far I don't even have one. The plants are huge and taking over most of my side yard. I have tried hand pollinating and everything else. Although I did not see any signs of the SVB I did split the stem of one plant to be sure. I found nothing. I have no answer. Hopefully next year will be better.
