Tomato plants - no flowers?

My wife bought some tomato seeds from the local Supermarket (Sainsbury's), and planted them as instructed. The seeds grew as expected and were transplanted into 2 growbags, 4 plants in each. The plants have grown and are at about 4 feet tall. As yet there are no flowers on them. I have none on all 8 plants. I have never encountered this before, although it is a number of years since I have grown them. The variety on the seed packet is Gardeners Delight. They are a cordon variety
Is this normal or is there a problem. The growbags are kept moist and are in a South facing porch at about 20C.
Thanks Bill W.

 

4 feet already tall for this time of year , have you fed them and if yes with what , I think not enough light or warmth to get them into flower and thats why they are so tall as well

As I said they are in a South facing all glass porch= Plenty of light/heat. Fed with Tomorite.??

 

You should not feed tomato plants until the first fruit sets, that may be your problem, if fed they put all of their energy into leaf growth.

 

Welcome to GC Bill! I grow Gardeners Delight and they are usually prolific fruiters. I agree with Jazz above regarding feeding. There's also the possibility that although they are in a light area it's not enough for them and is why they've grown so tall and not set flower trusses. Tomatoes need sun especially when it comes to them ripening.

 

Yours 4 ft tall heliwilly, hmm, mine aren't much taller than 4 inches far less the liklihood of a flower in sight but unfortunately I know what the problem with mine is, lack of that big orange ball in the sky and therefore b all warmth. Agree with the others tho, perhaps you have been generous and fed them and consequently they are too "fat and happy" to bother to try and flower!

 

totally agree there. All I have is leaf still but it's early days and we all suffer from a lack of patience.
Welcome to Gardeners Corner Bill. The trials and trauma of growing tomatoes... but they ain't 'arf nice when they arrive and they are all YOURS ,

I agree with all that has been said it is way to early for flowers and for feeding

 

My tomatoes have got flowers on them and are small for a tomato plant at this time of year. They are between a foot and foot and half tall. Is this normal?

This is how tall they are.

 

If you can maybe buy a couple of plants from a nursery, this might help you with an earlier crop.

A high potash feed (eg Phostrogen) will help the plant to produce some flowers.

Summer is nearly here, (6 days) so all should be well very soon

 

@heliwilly are they tall & sturdy, or tall and lanky?

If they're not going to flower then some immediate action needs to be taken, or you probably wont get any tomatoes this year:

1) Buy replacement plants (far too late to sow seeds).
2) Let some of the side shoots grow and put them in a jar of water to root then pot up. Rooted side shoots will produce flowers lower down than most seed sown plants.
3) Let side shoots grow and if they produce flowers pinch out immediately after the truss.
4) A combination of 2 & 3.

 

Looking good

 

is it even normal for them to have flowers on them even though there are so small and the fact that it isnt the right time yet?
