Have been growing these trees for a few years now (bought from fellow Asean Now member GraftingKen) and am really happy with the crop this year. Nice big clusters of fruit on my Spanish Lisbon trees. 

I've gone ahead and thinned out some of the smaller fruit, just to give the others a little more space (and energy) to develop. 

Happy days! 

 

The other 2 sickly fruit (different tree) don't look like they are doing so well, which is a mystery to me as all trees get the same watering, manure, mulch and sweet loving care. 

I have similar result. Newer trees that just got up to production does very well this year. Both larger European type and smaller Thai variety. Seems it's important where they grow. In some spots they just aren't happy.
