Blossom End Rot - Toms

[Chitfaced]

I think I've spotted a few unripe roma toms with blossom end rot. I can't work out if I am not watering enough, or the heavy rain has confused them or what.

What should I do to prevent it from happening to others? Should I pick and discard the ones it has started on?

I wouldn't mind so much if some of them were turning blimmin red.

I had blossom end rot last year and was told it was caused by irregular watering. I didn't discard them though, just cut the bottom bit off, they were fine.

Love the blog

some varieities are more prone to it as well, so you can either be super careful and water religiously, or just accept there'll always be a few on the plant

Where are they (greenhouse or outside, pots, open ground)

Blossom end rot is caused by a shortage of calcium posibly as a result of irregular watering. The only source(as far as I know) of soluble calcium is calcium nitrate and a watering with a solution of that should remedy the problem although fruit already affected cannot be made good again.

A few toms on a few of my plants last year had this problem, but they were all watered at the same time as the ones that didn't get it, IYKWIM. I still used the tomatoes, just cut the rot off and used them to cook with.

Thanks all. Rustylady this particular plant is in a pot on the decking, has been outside now for two months. I always water from the bottom as it stands in a deep saucer. I've also added one of those hydro globes to supplement water when I am not there on a warm day.

I've been reading another thread about having limited trusses to encourage healthier growth of the present fruit.. might look at that again as I have lots of trusses and no ripe toms yet.

Thanks for your comments.
