Blossom End Rot
Aw, that sucks. Last year a big rain caused this in a third of my roma tomatoes, I was so sad.
I'm now the proud owner and user of a calcium spray to try and prevent this.
Are they covered? After two seasons of pure endrot I bought a shabby little "greenhouse" to grow my tomatoes in. Fingers crossed for this year.
Something I'll have to plan for next year! Not very feasible where they are this year. Hopefully the rest don't mind the sun too much this year!
It's more against the rain. Although some shade might be helpful too.
Amish trick. Spray your tomatoes with milk. The calcium stops blossom end rot. Spraying milk is also effective against many tomato fungus.
