Re: greenhouse-tomatoes: Cluster Problems



I see this problem every year in some houses.  The answer I always get is N is too high.  Tissue samples haven't verified this however.  Other possible answers have included ethylene damage or cloudy weather.  I'm not satisfied exactly what is causing the problem.  When we see this the flower stems do seem to be more erect.  They sometimes even grow another leaf or plant from the bloom area or have 20 blooms instead 5-7.  All ideas are appreciated.

Michael,
 
        When flowers do strange things I wonder if plants are out of balance.  Are they perhaps too vegetative, especially given the hot weather?  Are the flower stalks unusually erect?  When the infloresence is more nearly vertical than horizontal it can be an indicator of bullishness.  Is there plenty of pollen?  If not, that's another indicator, as are pale flowers.
       
        If you think there's a chance the forking is caused by vegetative plants, by all means, cut back on N but try increasing EC, probably with K, to move the plant in a generative direction.  Extra leaf pruning may help too.
 
        No guarantees, but that's my first reaction.  Maybe it'll help start a discussion that has some value for you.

I’m having a problem with my crop right now. Many plants (var. Match) are producing a cluster with two flowers and then, if allowed to grow, a second set of flowers with 4 or 5 flowers will begin to develop on the same cluster. These are elongated but other wise well developed.

 

In the past, I’ve experienced a leaf that would grow off of a normal cluster. This was remedied by cutting back on N. Keep in mind that we have been experiencing some funky weather. 81 degrees F in the morning and 98 degrees F in the afternoon……this is October in North America isn’t it?

 

Any help will be greatly appreciated.
