The toms and cues i am growing in the same porch I have grown them for 3 years have no fruit on them.  They all appear to be healthy plants but very few flowers and no fruit.  What is wrong or just too early.  I sowed them over Easter.

Is it a closed porch?  I'm not sure whether insect pollination is needed for these plants but if it's closed then that would have an effect.

Try watering with a high-potash fertiliser (a tomato feed or simply sulphate of potash according to instructions on box) to stimulate more flowers.

I have been feeding tomorite once a week since the first flower on any of the plants.  I thought the cues were self fertilising and I have 8 tomato plants close together but I will the inside door open during the day to see if that helps.

Tomatoes are self-fertile - tapping the canes can help.

If they are indoor cues, they won't need pollinating.
