Went away for 5 days and came home to this!
Green and ripe tomatoes are starting to discolour
Last year they rotted from bottom
Thinking of giving up on tomatoes

What variety?

What colour are they now?

Sorry. Duplicate.

Too much water, not enough water, the same result, but if you don't rotate and plant tomatoes in the same place following year, many diseases will overwinter, especially after a mild winter.

Possibly late blight?

try moving them to a different location next year?

Thanks everyone
Yes they were rotated from last year. Chang place every year
Just can't win
Ps they are beefstake and one plant of sweet millions I believe was the name of the little cherry tomatoes

I'd ask if they were sun scalded, but I'm not sure if there's many places in Ontario that remembers what sun looks like lol. Do you have pictures of the tomatoes?

Ive read that bottom rot can happen (on the fruit) if the plants don't get enough calcium. I've had this problem in past years. This year I gave my plants a few doses of calcium through the season and so far have had great outcomes.

Can't really say without pictures.

Blossom end rot IS caused by lack of calcium, but that is caused by uneven watering.

Dying from the bottom up sounds like the fungal diseases we get here (Septoria, Early Blight). Removing those diseased/dead leaves as they happen can help to stop the spread of the disease and it doesn't usually affect the tomatoes. Prevention would be spacing the plants adequately, pruning to no more than three stems and using a mulch to stop rain from splashing up "nasties" from the soil. Some people spray with fungicides.
