..its black inside.. ;)

That tomato looks fully ripe..I wonder if the seeds have started to germinate inside and then gone off.

I get that in Roma occasionally, I just cut those bits out since I don't eat the seeds anyway. They are a bit prone to BER for me so I agree with Davyw.

It's not Blossom End Rot.

As the name of the disease implies, symptoms appear only at the blossom end of the fruit.

I hate being technical cos i am not bright enough.

If you want to be specific it is actually a decease called Blackheart, the tomato starts to rot on the inside just as in the picture. So what causes this to happen

It results from low calcium levels or high amounts of competitive cations in the soil, drought stress, or excessive soil moisture fluctuations which reduce uptake and movement of calcium into the plant, or rapid, vegetative growth due to excessive nitrogen fertilization.

I think that means irregular watering......and what causes Blossom End Rot

A possible cause, but not always. I think what you wrote is a better example.

This is the cause of Blackheart
It results from low calcium levels or high amounts of competitive cations in the soil, drought stress, or excessive soil moisture fluctuations which reduce uptake and movement of calcium into the plant, or rapid, vegetative growth due to excessive nitrogen fertilization.
It is also the cause of Blossom End Rot and how on earth could anyone treat Blackheart if you dont know its there till you cut a tomato open, just like BER you wont get it on all the crop.

You are the tomato grower and Hoticulture Studant i would have thought you may have been more informative and tell me how to treat it.

Have a nice day

Davy - I haven't had BER for many years here, which I put down to how I water my plants. Now if I ever did get it I would first check the pH of my soil, aiming for 6.5, then I would dose the effected plants with Calcium Nitrate (soluble) in a watering can. The dose can be found online easily enough.

I should think all who grow tomatoes know what to do if they get BER you asked

All i can say is i dint know how to cure something i cannot see but if i did find a tomato with Blackheart then i would treat it as if i had blossom End Rot

Tell me how you would treat Blackheart

Blackheart is an environmental disease of celery and potatoes. In celery it is caused by calcium levels in the plant that are low in relation to the potassium levels.In potatoes it is caused by insufficient oxygen in the centre of the tuber that results when soil is waterlogged or temps are too high,it also occurs in storage if ventilation is poor or tubers are stored for a long time near freezing.

Blossom End Rot again  is an environmental disease often caused by improper watering or a calcium deficiency when fruit is forming.It can be caused by several other factors as well,. It most often occurs when plants have been grown under favourable conditions in the early part of the season and are then subjected to periods of drought while the fruit is in the early stages of developmen. Under these circumstances the cells at the end of the blossom fail to receive sufficient water to grow, BER can also occur after a period of heavy rain because many small rootlets die off from lack of aeration in the soil.Overdoses of nitrogen hinder the uptake of calcium which aggravates the problem,it can also be caused by excessive root pruning which results from heavy cultivation too near plants.

It also occurs in squash and peppers.

To sum up
Lack of water at a critical time
Too much water
Root damage
Calcium deficiency

The calcium deficiency is usually not the cause, it is the plants inability to absorb the calcium usually.
Check your PH to rule out calcium deficiency..should be between 6 and 7,if below 6 correct with limestone which contains calcium. Don;t add if not needed it will not help. Bear in mind it is not the whole plant that is calcium deficient if BER shows up on a fruit so feeding with calcium will not help if the soil is OK.

Symptoms are..sunken dry,brown to leathery spots that always develop near the blossom end of the fruit.

Treatment.. avoid adding surplus nitrogen , water consistently all through the season, cultivate the soil as little as possible if plants are in the ground during dry weather to avoid further soil drying out. Test for ph and adjust only if needed.

Plum tomatoes are more susceptible to BER and it is usually only on the first fruits of the season, then clears itself up.

If there was no external sign of damage your tomato does not have BER either.


For anyone who suspects they may have BER ,check your tomatoes on the vine for any sign of black at the blossom end, it can show up in the green stage or when the fruit is ripening, it hastens ripening by the way.

My answer to your post was that it was not Blossom End Rot, now if you want to call it Blackheart, or Blossom End Rot that is entirely up to you.

Hi again, I just read my post again and part of it is misleading.

I started by arguing that it is not Blackheart which it is not for sure,.

I then described the cause etc of Blossom End Rot.

All that part is true but I neglected to add the word usual  when describing BER, all that I said is pertaining to the type of BER we usually see, however this neglect fails to fully describe the problem fully. Had I not been going out in a hurry I would have added the following which I  seemed to have left off.

There is a form of BER that does in fact happen inside the fruit, it is not common and is Internal BER, I am sorry but in my haste to answer fully  before I had to go out I lost the plot for a moment. It is a question I have answered many times and have to admit I just followed my usual spiel and neglected to add the bit that really mattered.

So, I will say again, usual BER is only seen at the blossom end of the fruit.. It does not start at the stem end. 

Internal BER can begin in the centre of the fruit. I would expect you to have more than one fruit affected .

Everything else in my post is accurate, and bear in mind usual BER is the one most often seen.

I am sorry if my post confused anyone.

I would say yes your fruit definately has Internal BER, not the usual one we see and are asked about often.

Jeannine that is quite informative. I do find that BER comes on my first toms, as they just have it now!  :'(  But it is not all types, and usually only on the first ones (which is all the more disappointing). For the last couple of years weather has been chaotic, with drought periods, then unseasonal rain and varying temps. As I grow outdoors there is little you can do to prevent it. But I agree that it usually goes away once the fruit is properly developing and ripening at full speed!

I'd imagine that the number of fruit involved would be miniscule compared to 'ordinary' BER and may only involve one single plant in the garden, that treatment wouldn't be needed as it should correct itself. BER problems are more complex than assuming too little or too much water is to blame, as it can be a number of things that trigger it. Then, by the time you have found any damaged fruit you'd need to ask yourself has the problem rectified itself as you cannot see it or do I treat the plant, when what you give it may do more harm than good.

Yes, the causes and preventatives are exactly the same..bear in mind however that adding calcium is useless if the soil does not need it, it is the plants inability to absorb the calciul usually not lack if it..

Water evenly and regulary, don`t let plants dry out especially at flowering time, don`t overwater and remember it is  often  only on the first fruit, plums are most prone and the fruit is still edible,,it is not catching. Oh and it is more prevalent in containers as watering is more difficult to regulate.

There are some varieties resistant and some more prone..I will get you a list .

Cornell Uni put out the following list of BER resistant varieties but I have no personal experience with them and BER

New Yorker
Old Brooks
Thessalonika
Manalucie
Black prince
Wins All
Mountain Spring


It is curious that Mountain Spring is sold as BER resistant as is Lisa King. I have grown Mountain King this year and Old Brooks, both are also said to be blight resistant. I don,t have BER or blight at6 all yet in any tomatoes though.

Also to note,cherry tomatoes are usually unaffected.

Still working on a sensitive list

Thank you macmac.  I really appreciate your efforts (!) to explain clearly.  But I don't think  it will help me.  We keep our photos on the computer, and we've realised that what we don't have in our "additional options" is the ability to 'attach'.  I don't know why, perhaps that isn't something A4A allows.  But what I'll do next is to post a specific question.  I asked you as you had clearly been able to put in a pho;to.  Thanks anyway
