Problems with my tomatoes

Hope you don't mind me tagging on to this thread, but I have lots of toms developing in the greenhouse.  A few of the developing toms are going very dark on the underside though.

Should I be worried?  Should  cut these out or get rid of the whole plant?

Hi Smag, are the brown bits on the bottom of the fruit where the flower was?  If so, sound like blossom end rot, so just get rid of those fruits that are affected.  Keep the plant though unless all the fruit go like it.

I have some toms where the bottoms are splitting in a funny shape rather than going brown, but I don't know what that is.  It is only on one particular variety too!

Have a look at this article:

Thanks Annie, and for the article too

Looks like mystery solved

Sorry I can't help you with your bottom splitting (toms) though..... sounds painful  :shock:

Take a look at the thread I wrote you on 3 July re the mark at thew bottom of the brandywines. - Oliver

Hi Qwiz, no I don't think its the too dry then too much water thing, when that happens to me, the split is usually round the middle of the tomato.  

This thing isn't a split, its like zigzagged lines or a gaping hole where you can see the tomatoes inner bits and its on the bottom where you get blossom rot, but its not rot.

Message for Oliver.  Sorry Oliver, I didn't see your July 3rd post for some reason, so you think its because I may have more than 3 trusses on those particular plants?  I did read the other day that with the big beefsteak types you should only allow 3 trusses and 3 fruits per trussl, but that means you only get 9 tomatoes per plant.  That's not fair!!!  I want more!!!! lol

Anyway, I've tried it with the yellow brandywine to see what happens, mind you, only one of them was more than 3 trusses anyway, but it isn't happening to my other beefsteak toms like Big Boy and Marmande.  They are fine.  However, I am going to reduce some of them to 3 fruits and 3 trusses per plant, and leave some of them with more fruits per truss to see what difference it makes.

I'll tell you what it looks like Oliver, you know sometimes you get an orange that has a tiny orange growing inside it?  The bottom of the big orange looks holey and has bumps inside it?  That's what they look like.  But didn't want them to keep growing looking like that, as it looks like an open invitation to bugs, but if you reckon I should leave them and wait and see, I'll take your advice.  

Do they taste nice?  It could be that it gts too hot in the poly, The chillies love it, they are coming on a treat, and the Tigerella toms are looking good.  Gardener's delight not bad, some missing mid truss, but other wise good.  Floridity looks good too, and Big Boy and Marmande.  In the greenhouse, there are lots of Tres Cantos coming along, but again the brandywine lok the same as the polytunnel ones.  

Melons are looking good at the moment too.  The biggest one is tennis ball sized now, and on 2 plants I have about 10 melons.  Should I take the other flowers off or leave them?  There are no fruits yet on the melons in the greenhouse
