It appears I have a small problem with Blossom end rot, about 4 toms so far but lots still untouched.
Anyone got suggestions about how to treat, I do regularly water at most missing one day a week.
They are in my greenhouse.
Thanks

Blossom end rot is actually caused by inadequate delivery of calcium, amongst other things to the fruit.

Poor watering is not actually the cause of the rot, but can be the cause of poor calcium delivery.

Here's a good link....

Thanks DD most helpful.

Yes, thanks DD.
Our tomatoes are suffering from this but have been regularly watered. OH has been using his 'special' fertilizer made of chicken poo and nettles! Other than that mostly rain water is used.
In what way can we put the calcium back? I have looked on the tomorite bottle but it doesn't mention calcium. Any help would be gratefully received.

The link recommends a foliar feed with calcium nitrate.

Here's a link to such stuff.....

Sorry missed this bit.

You can't treat, you can help prevent.

I've never had it in toms grown straight in the soil, interestingly enough. Nature wins again!
