Are my tomatoes slow or am I imagining it?

    Hello, greetings from sunny Shoreham-by-Sea.

    My tomato plants - that's the plants - are incredibly healthy and lush, but it seems to me that the fruit is very slow to form and grow.

    Is this so, and if so, why, or am I imagining it?

    Many thanks

    Neil

    Mine are the same this year, lots and lots of growth but not many ripening. I put it down to the weather, today onwards we are getting sun which is what is needed.

    Although you are saying your fruit are very slow to form, are you getting your flowers pollinated? Giving the plants a little shake every now and then to transfer the pollen (assuming they are in a greenhouse) ?

    Once the fruit set you need to be feeding with a high potash fertilizer to encourage the fruit to swell.

      Thanks for that. They're outside, south facing, and, yes, they seem to be getting pollinated okay, but will give them a bit of a shake! Good idea. And am feeding, so can't really do anything else, it seems.

      Well outdoor tomatoes are always much slower than in a greenhouse, in a normal year I wouldn't expect to be picking any yet. I've just pinched out the top of my outdoor toms, stopped at three trusses, this makes the plant put all it's energy into swelling the fruit - but we need sunshine to actually ripen them.

        Oh, okay, three trusses. I've always stopped at four previously, with pretty good results, but perhaps I should trim to three this time.

        If four trusses have worked for you in the past then stick with it. I guess you are a bit milder than me being down on the coast, when do you normally get ripe tomatoes?

        Do you know, I can't really remember, except it certainly seems as though it was earlier than this.

        I can't recall getting ripe tomatoes outdoors before August in the past.

        I read a book some time ago. It suggests that leave only one truss, but plant 4 times as dense. This way the plants don't need support and the fruits will ripe sooner. I may give it a try next year.

          I've got my first outdoor one ripe, its a "sweet million".
          I think its a bit early, especially bearing in mind the rubbish weather, but who knows.

          I've only planted four plants on the allotment and got them very well spaced this year, hoping the airflow around the plants will go some way to avoiding blight.

            @JWK, I always have problems with blight, have I understood this properly (sorry to be so dim :doh:) I have to nip out the top of the tomato once it has three or four trusses, then should I start removing the lower branches to encourage air flow? I've not done any of these things in the past, I will be so disappointed if I get blight again this year :sad:. I've also stopped wetting the floor of the greenhouse as I've been told that increases the chances of blight :scratch:, someone else said it helps the tomatoes because they like humidity? I'm really confused! Any help you can give me will be much appreciated :thumbsup:

              Hi Beckie,

              If the lower leaves are touching the soil then they should be removed. Otherwise they can be left along

              Tomatoes like moisture but only for roots. The above-earth part need to be dry. You should not even wet the leaves when watering them.

                Hi @blacktulip, thank you very much for your advice my friend :grphg:, I'm always very careful when I water, I literally kneel down & only water the soil in the grow bag, in previous years I've also watered the floor in the greenhouse, but I wondering if that's some of the problem? :)

                You are most welcome :) humid air definitely helped the fungus spread. Greenhouse tomatoes don't usually get blight since they are shielded from rain water. Try keep the greenhouse as dry as possible (keep the door open etc) and your tomatoes should be fine.

                  That's interesting; yes, worth a try. And perhaps I am imagining it, then, John.
