Allotments 4 All

Hi there,

I've grown tomatoes in gro-bags and the soil for years and have never had this before.  But my crop of Marmonde variety tomatoes have all got black spots starting at the bottom of the fruits in those posh tomato gro-bags that have all the right nutrients in there.

Do I need to feed them more often?  Is it something to do with the awful summer we've had?  Any good tips on what to do to save the crop?

Any advice gratefully recieved.

Blossom end root is usually due to a lack of calcium being laid down in the fruit skin. nothing can do about fruits that already have it but some advice here on how to prevent in the future

Thanks - that's good advice.

Give them a feed of Calcium Nitrate, and keep watering regime as even as possible.
