Yes but how do you get the 3 balls.

Do you cut the leader at say 30cm, and let it shoot out - to start the
first ball. Then pick a good vertical shoot to start the main stem
again, and do the same at 30cm, etc to make the 2nd ball and again at
30cm and then cut all leaders to make the 3rd ball.

Or do you keep the main stem going to 1m, cut the tip and hopefully
pick 6 good side shoots (2 a side) to start the balls.
