Hi Willsc,
I think that the question was more: " how many kg of fruits did you harvest ?"
To see if that way of growing is efficient or not . Growth is good, but I'm more interested in fruits :) .
By the way, you should still be harvesting ? don't you ?
What I would try next year, is : let the shoots grow and pinch at 3 nodes, and then let them branch and grow .
That will slow down the growth while giving more branches for fruiting - hopefully.
As for not branching, I have the same problem. If I don't pinch, they don't branch out and go flagpole style - then most get pinched in winter and thus I get branching every 1 meter or 1,50 meter.
I'm more interested in seing how you prune back each year :) so, if possible, don't get rid of that bed ... Grow a new one - that would help you compare different strains.
I would be interested in knowing if in the future years, the trees would be more productive, fruit be bigger ...
If you're looking for ideas of new strains: Pastiliere, Dalmatie, Longue d'aout, ..., are known for their small size.
Blackmadeira would be a good candidate as it seems to be slow and sought after for cuttings :) .
As for the height, the more branches, the shorter the branches will be , so I would try tricking them to branch soon in the season.
