Dutch Passion Blueberry !!!HELP!!!

I just purchased blueberrry (feminized) by dutch passion and i cant find out any grow tips for this strain, i.e, topping prunning, special conditions. This is my 2nd year growing 100% organic. Last year i started my trial season with feminized White Rhino by GreenHouse with good results (about a pound off 3 plants outdoors). I believe one of the mistakes i made was topping... need some advice if anyone has dealed with growing blueberry outdoors.


Here are some pics of my grow last season. 2 are from my White Rhino.
