tomato blossom end rot Qu

| Just wondering if someone can answer the following:
I have several different tomato plants in a garden bed, including grape, cocktail, Beefheart, Roma and Gross Lisse. They are all treated the same (staked, fed, watered, position etc); Two of the Romas are going great, while the third's fruit all has blossom end rot. They are all fruiting well
I've read that it is usually due to irregular watering; is there some other cause(s) as, as been stated earlier, they've all been treated the same.
Thanks, Maria |

Romas and paste types in general seem to suffer from blossom end rot (BER) more than other varieties. I don't know why.
It's thought to be due to lack of calcium in the fruit. This is not related to how much calcium you have in your soil, except if you had none whatsoever but that's not the case. It seems to be related to the plant's inability to to get calcium into the developing fruit. Stress seems to be the major factor and irregular watering is often the main culprit. But not always!
It's quite common to have just one plant in an entire patch that suffers from BER. I wouldn't worry about it. It happens to almost everyone. This year we have BER in one plant in a big patch. It's a roma type.
I've found that heavy mulching reduces the incidence of BER, but it doesn't eradicate it. |

Fertilisers with their nitrogen as the ammonium salt can cause BER as well I think. But as they are all being treated the same, it could be some slight difference of the nutrient content in the soil where the affected one is.
I had a lot of BER last year on lots of plants and I put it down to over fertilising. This year the only plants that have suffered have been in pots that I have fertilised a few times. The rest of the plants have had compost only. |

| thanks raymondo and ozmantis for your replies now, it seems that overnight, ALL of the plants have had their leaves from the bottom to about 2/3 of the way up go brown! What fruit is there, still appears viable and plump Would this be a fungus causing this sort of thing?

| Maria, I hope it's 'only' the recent heatwave that has affected your plants. Mine look the same. Yellow leaves from the bottom up and some leaves are crisp. I sure hope it's the heat and not some disease that requires me to pull the plants. Good luck! :) |
