Tomato plants not pollinating

Hi all, 

I've been growing sweet aperitif tomato's this year in my greenhouse. 

I've enjoyed a fantastic first crop off of all my 9 plants but for some reason all the flower growth above 4 feet (and there is a lot!) Just sit there for a week or so then die. No more tomato's growing to replace the established fruits. 

I've been shaking the plants, making sure the air is circulating with a mini fan, the door has been left open for a good 6 hours every day and I've even been in there with a paintbrush hand pollinating, all to no avail.

Does anyone have any ideas what I could be doing wrong or do tomato plants have a finite amount of fruit they can produce?

I feed them twice a week and water every 36 hours. 

Thanks

Dan

    Hi Danjacks. When I grow tomatoes I always 'stop' the plants when they have seven trusses to enable them to ripen before the days get shorter. I think that watering every 36 hours may be a little too much and I only feed mine once a fortnight. I take off all the older, yellowing leaves that are beneath the first truss too.

  • i mist my tomatoes with a little water sprayer and this is supposed to help flower setting image

  • Thanks for all the advice. I'll give it a shot and see if it helps 

  • hi danjacks     as a few say watering that long I grow mine in plant pots standing in   washing bowls from pound land standing on block paving and I water in bowl to about 3inchs up the plant pot  and I feed once a week at start  when plenty on trusses 6 or 7  or 3or 4 for the big toms and as garden archaeologist says mist and phillipa says tap stems is enough to pollinate them   (only thing I would say is don't let them go so long without water )  some say stick your finger in m/p c and if dry 3 or 4 insh  water .  (on a little tip I snip of a few of the flowers of big trusses  say 15 flowers on snip4 /5 of so as not to over load plant stems )   hope it helps      Michael

    We've had a lot of strong sunlight ... are the flowers just getting too hot up there near the roof of your greenhouse?

  • That (blossom drop) can be caused by feeding too much and watering not enough!
