    Am I the only one who has plenty flowers on their tomato plants but hardly any fruit? I do have odd ones but they are small and most are appearing now and its July. I'm in Newcastle upon Tyne and the weather this year here hasn't been very good and had a lot of cloudy days compared to last year I was harvesting in June. I know the South has had high temps but sadly not here on most days.

    I have the same issue. Last year picked first cherry tomatoes (outside) on the 1st of July. This year I have a greenhouse, and the season didn't start properly yet :( . Just 1 Super Marmande tomato, and 5 black cherries. All the tomatoes are still green, and loads of flowers. Had to top plants.

    All I can think is too much feed. They should not have any until the first fruit set, then just use a high potash feed after that. Too much nitogen encourages leaf growth.

      I’ve been picking tomatoes for a few days now, maybe a week. Sweet Petite, Honeycombe and GD. Sweet Petite is very tasty :)
      Agree with JWK about overfeeding ....overwatering too causes lush growth at the expense of fruit I think. :noidea:
      I also remove lowest leaves and continue to do so as the season progresses.....I think it helps air to circulate better as well as exposing fruit to the sun. It gets to the point when I simply want the fruit to ripen and I remove every leaf. It means no fruit in September but a bumper crop of ripening fruit in July and August. Prevents any late blight too I think :noidea:

      I've been getting tiny yellow ones (don't know variety) for couple of weeks, but not enough for a salad - just a couple at a time . I bought some cheap remaindered grafted plants, and they did seem more robust than the others on their own roots, but no difference in speed to fruit.

      I fed mine liquid tomorrite tomatoIMG_20190723_172001595_HDR.jpgIMG_20190723_164252604.jpgIMG_20190723_172041066_HDR.jpgIMG_20190723_172001595_HDR.jpg fertilizer high on potash and less than recommended. But to be fully honest, I have another varieties than I did last year. And I kept more stems than recommended. I did remove lower leaves, but my green house is full. I step in into jungle :):

        Same here. Greenhouse is a jungle but I’ve been picking toms for a week now, so far of four varieties. Two more varieties yet to ripen. Even my outside ones are ripening now.

        I agree with the above comment that we are behind last year. I think this year May was colder than is usually the case. Also June was wet. These two factors mean we are a little behind. I’m not worried though; looks like it could be a bumper year.

          Sounds like poor pollination, have you tried tapping the flower trusses a couple of times a day when the flowers are open.

            It's difficult to see from your photos @Alisa but it looks like you have lots of side shoots? Black cherry is a cordon type and needs side shooting otherwise you get a mass of stems, leaves and tiny fruit.

              Yes, appears I kept too many branches, plants just would start "forking" at the top, and I let them to do it. So all of my plants ended having 4-5 stems. Then I started properly pinching away all additional side shoots. Black Cherry is a separate story. Information on seeds package did say: bush, no need to remove side shoots. And picture supposed height up to 1.2 m. Only later I started searching on internet what's wrong with my plants, why they keep growing so tall. Will apply more theoretical knowledge next season. Now to get tomatoes grow and ripen I pinched main stems, and try to remove leaves (slowly - not at one one go) where they seem to be too much close.

              Plenty of fruits setting here, they're just slow to ripen this year. It's a common complaint around here this year, indoors or outdoors. We've put it down to a lack of good sunshine and a lot of cold nights until very recently. All that said I'm just about to enter a period of plenty at last!

              As an aside I'm trying something different with my Supersweet 100 as I have two of them. On one plant I'm allowing sideshoots to grow until they set one truss each and on the other I nip the sideshoots out. So far they seems to be producing equally full trusses and ripening at the same rate, just that one plant has the extra trusses of the sideshoots.

                You probably overfed the tomatoe plants.
