It is often caused by a calcium problem. Often it is only in the bottom of the tomato and if you are really keen and pick them quick enough you can use the top part of them by cutting above the affected part. My Dad grew tomatoes every year without fail. He usually planted them around the 23rd – 25th Sept. (I remember the dates because of family birthdays). By that time we were less likely to get any more frost and the soil had started to warm up. He tried various methods of balancing nutriment in our soil but it was still a problem.

My vegie patch is only a couple of months old and I’ve got tomatoes in there. I’ve never had much luck with tomatoes before so I’ll be following your answers – just in case.

Also; I believe this has been a fairly common problem lately. I received a bucket of tomatoes and unfortunately they were all in poor condition.

Possibly seek some advice from a garden nursery for the future? See what you can salvage and use in the kitchen.

Mine has also done this in the past and yes they still make great relish or sauce.

It could be a number of causes – fungal, insect or more likely calcium deficiency. Try some specific tomato fertilizer or folar spray of dilute calcium nitrate or calcium carbonate (lime) – you should be able to pick these up at the hardware store or nursery. If you have sheild bugs spray bugs with white oil.

We had the same problem with one of our plants this year in qld! As above research blossom end rot and you can still eat them just cut the bottoms off we made a relish with ours which turned out great!

It is blossom end rot. Check it out on Google. Can be caused by over or under watering, lack of calcium and moist humidity. Has not been a good year for growing this year because of the overcast days here in Victoria. If the rot isn’t too bad you can still eat the top of the tomatoes – the taste won’t be affected and the rot stays in the one spot. This is usually where the flower/blossom is attached to the fruit.

Ours have done the same thing. I’m sure what state you’re in, we are in Victoria and ahve had such a strange summer so far. Our few tomatoes have remained green and don’t look like ripening and the bottom leaves on the plants are dying off before we get any tomatoes. Very disappointing.

With your tomato plants, make sure the bottom leaves don’t touch the soil as it causes leaf rot. Just cut the bottom leaves off.

Mine did this last year, are they in the ground or in containers, My father assured me that it was irregular watering that causes it, especially if they are container plants as they may dry out during the day, even if u water them daily, it is called blossom end rot, it can apparently be caused by under watering, over watering or calcium deficiency, there is some great info on google if you look up blossom end rot, you cant save the damaged tomatoes but can save the plants and future fruit, very disappointing thing to happen, I cried!!!!
