Need help!! I have big, beautiful plants as a result of amending soil in the fall, but a few of the blossoms are yellowing and falling off, due to me adding too much manure, I think. What’s the best way to correct this. They’re only on their first truss, so I was thinking I should add seabird guano. (0-12-0)
Anyone else have some thoughts on this??

Anytime I had those yellow neck death blossoms, I just waited it out. Grew higher up. If you know yer on the low side of phosphorus, it might help. Good luck.

Can u post a pic of your plants? There are micronutrients that could be deficient and/or poor pollination. Also excess nitrate in the plant and water/calcium fluctuations in the plant. There are solutions but first gotta figure out the problem. Pics of the plant, and flowers, might help.

Are you by chance using a fertilizer with potassium chloride? Might not be a good fertilizer for them. The manure might be high in sodium and/or chloride. And potassium. But this is speculation. A good answer of what to do requires a little bit better knowledge of the problem.

As porkchop notes, eventually nature usually wins over nurture and at some point nature will get them to set some fruit to reproduce. It's common to have transient problems. It would be rare to never set any tomatoes at all.
