I bought a greenhouse this spring because tomatoes always struggle in my foggy climate. I was so excited with the amount of fruit so early in the season compared to my usual grows. Today, I picked the first two, which I thought looked perfect, and flipped them over and they were rotted. Of all the many problems and disease I've had over the years, this is a new one. I'm wondering if it is because they are in pots and having trouble taking up enough nutrients? I ordered some calmag, so hopefully that will help. I don't see the BER on a few other fruit I checked, so maybe I'll get some ok maters.

    Calcium uptake problem. Short term add a few tums to the water. Ease up on the nitrogen fertilizer.

    Very common on the first fruits of the season

    Despite the BER, they are gorgeous! Celebrate those first beauties, cut the bottoms off and make a caprese salad.

    I have a feeling my tomatoes are going to have a huge problem with this because it WON’T STOP RAINING. Ugh.
    I almost think I should replant. But it’s never dry enough.

    Wow, mine are still seedlings. Only weeks ago we still had snow.

    You can still eat them. Cut off the gross looking parts and the rest is safe and tasty.

    Just cut it off, you still have most of a tomato and homegrown tomatoes are worth using even with problems.

    Per chatgtp…..
    Yes, tomatoes with blossom end rot can still be eaten — but with caution:

    ✅ Edible Parts:

    You can cut away the affected area (the black, sunken, leathery part at the bottom).

    If the rest of the tomato is firm, red, and healthy-looking, it’s safe to eat.

    ⚠️ Caution:

    If the rot has spread into the flesh, making it mushy or moldy inside, discard the whole tomato.

    If you see any fuzzy mold, bad smell, or oozing, do not eat it.

    Tip:

    Blossom end rot is caused by calcium deficiency or irregular watering, not by pathogens — so it’s not dangerous in itself.

    Would you like advice on how to prevent it in your garden?

    Blossom end rot.

    Give your plants a calcium supplement and it will help prevent it!
