Is there a way to speed up flowering on tomatoes?

[senua]

I have some lemon citrina tomatoes that I raised from seed which are just starting to flower. I took some side shoots off, put them in water and they have sprouted roots. It would be fun to plant these out but if the originals are only flowering now, from a spring sowing, how long until the sideshoot plants flower!? Is there a trick to speed things up?

Cuttings generally flower earlier than the seedling. The chemical messengers initiating flowering in the main plant are also present in any cuttings. That's one of the reasons for growing things like wisteria from cuttings or grafts rather than seed.

Otherwise I suggest you use tomato fertiliser, which contains the higher levels of phosphorous needed for flower growth rather than leaf growth.

That's good to know. Thanks. Mere, you are such a mine of info!

It’s a side effect of ageing. All sorts of random info sticks as if to flypaper, leaving no room for stuff like “what’s that thing called?” “what did I come in here for?” and “where was I supposed to be today?”
