Blossom Rot
 

Has anyone here had any luck dealing with blossom rot in yellow squash?

This is my first year gardening in a greenhouse, and my squash has gone crazy! It is huge and has almost taken over the whole greenhouse. I have tons of blossoms, and squash growing, and then when they get about 2-3" long, they sometimes develop blossom rot. I researched this disease, and it seems that too much watering, or not enough water can cause this, and also that not enough calcium in the soil can cause blossom rot.

So, I stopped watering for a day or two... that didn't help. So then I watered again... that didn't help, and then I applied Epsom salt 1 Tbsp per gallon to the plants... that didn't help.

Not ALL the squash have it, just a few here and there.

I have had end rot on my squash before but I have never known how to deal with it. Sorry!

I know. That is kind of what I have gathered from my online research. No one is really "sure" what the problem is...

I really wonder if it is because the nights get so cool here (down in the 40s), and if the squash just really don't like that. But the weird thing is that it is not affecting all my squash, only a few here and there...

Hmm, yeah, I know what you mean. Wish I could help!

Jeff had this happen with his first batch of tomatoes this year, and this is what he did:

He picked/discarded all the affected fruit, and then used Rot-Stop (which is basically calcium) and applied it 1x/week for 3 weeks. All the new fruit looks great.

"Blossom Rot." Wouldn't that be a good name for a rock band composed of backsliders?
