Tomato problem for neighbour

Our neighbour Juan grew his own tomatoes this year instead of buying plants.  They have grown into really bushy plants, look really healthy, but they lack one thing- tomatoes 
He grew the same type last year and had loads of toms, he bought plants last year too and his toms were far better, so he decided to grow only his own from seed this year.
He had fertilised the garden with well rotted horse manure, it was like fine soil,  last autumn and had a drip watering system going.
What could cause no flowers/tomatoes?  Out of about 100 plants he has just 2 toms!  By now he should be picking loads of fruit.  He said he is digging up the plants tomorrow, he isn´t wasting his water anymore (it is metered)
We were banking on him getting a good crop this year as we didn´t plant anything cos of the building work here
He also fertilises with what I call  ´sugar´ what ever it is looks like sugar,  he gives them a dose when the plants are young, other than looking like sugar I have no idea what it is! He sprinkles it in a thin circle around the plant.

That could well be the reason, also whatever he's feeding them could well be causing them to make leaf, not fruit.

It's been said many times, in bold, italics, red,  double underscored, not to feed until the first fruit has been set.

I take it you've missed that! 

When did he sow them? Maybe it's just a bit early yet and the weather hasn't helped. If he bought plants last year they could have been sown really early. I've got ripe fruit on one I bought a couple of months back, but the ones I sowed are no where near that stage.

Different country, Nobbie! 

Sounds like overfeeding (unless Juan's "sugar" is actually cocaine, in which case they are probably too spaced out to bother about producing flowers!) 

 

Now that might explain what my plot neighbour was drizzling round each of his onions in a small circle, from a plastic bag with a hole cut in the corner --  it did look suspiciously like.........

... and his onions are a loooooooooooooong way apart now
