Toms Not Forming on Plants

[Coll16]

Hi
I am new to this forum so please bear with me.
Most years we plant toms from the seed of ones we have eaten and liked. Every time we have done this, they have grown into lovely plants and toms have formed and we have enjoyed eating them.
This year I did the same thing and all the plants came up well. I put string on the tips to stop them falling over and they grew very well. But the odd thing is there are no toms on the vines at all. Plenty of leaves but no fruit.
Why is this? I hope somebody can help.
Thanks for reading.

Photos?

Have you been nipping out the side shoots and maybe taking the flower buds with them?

What varieties of tomato are they? Are they bush and not vines and need to be grown differently?

Perhaps the varieites were bred not to form fruits? If they are unknown varieties then they may be not suited to the UK. Are you getting flowers? Are they being pollenated?

Are you in the UK? Can you add our location to your profile? I can't see tomatoes growing this year now, however you need to know for next year! As Zazen said a few more details would help.

If the seed is from shop-bought tomatoes it is most likely an F1 variety so you really will have no idea what sort of fruit, if any will come from the resulting plant.

Have you been feeding your plants? Too much nitrogen will give you lush foliage, at the expense of flowers/fruit

That happened to one variety (black russian) in my greenhouse so I looked it up in an old Hessayon book, and he says the air being too dry at pollination time can cause flowers to drop off and the "dry set" of fruit. So perhaps misting the greenhouse might have helped.

I grow tomatoes in my house and this year I tried a new variety, Bajaja. I'm familiar with the fact that tomatoes need pollinating, so I tap the flowers to help with this. I've grown several different varieties and never had a problem until this year with Bajaja. It simply wouldn't set fruit indoors. I put the plants out in the garden and within a couple of days there were small tomatoes forming.

Maybe you have a variety that needs to be outdoors for pollination.

I've grown Bajaja for a few years now, both inside and outside, and not come across this problem. Maybe it has just been too dry for the fruits to set.
