Blossom End Rot and Roma Tomatoes

vodreaux · July 10, 2006

My two Roma-like tomato has Blossom End Rot (BER). My neighboring tomatoes does have the BER problem.

I started to mulch my tomatoes 10 days ago, possibly its to late. We had a heatwave 90-105 degees weather in the last 21+ days. The soil dried out my day, at least top side. I watered it occassionally during middle of the day due some of the plants wilting. BER must of started at least 7 ago and most recent tomatoes maybe up to 14 days ago had BER. The ones older than 14 days does not have BER, the larger tomatoes.

I read the following guide.

First Question:
Why do Roma-Like Tomatoes tend be more supceptible to BER?

Second Question:
Why is the best ways to combat BER? The guide and others stated Foliar Spray not really effective.

Third Question:
What among all the Tomatovillians is best way to combat BER from experience.?

"If pH is part of the problem (ie too acid)..."

Most places in So Cal suburbia are too alkaline.

Some of my Purple Russian's have BER. The cause could be any or all of the likely reasons. Can I use a calcium supplement to add calcium to the soil? I have a whole bottle with an added enzyme that I won't be eating.

Probably an idiotic answer, and I can already think that heart-shaped tomatoes should be vulnerable if this is true, but in roma tomatoes, I'm thinking the distance from the stem to the blossom is longer in relation to the body than most other tomatoes. Longer distance = harder to transport the nutrients.
