To remove suckers- cut them off close to the ground using the end of a knife cut out i.e.scoop out some of the growing tip i.e the centre ,if the sucker is no more than a hand's height, tip in to the prepared sucker a teaspoon of keroscene.
The kero. kills the sucker. I always use this method ,even for suckers that have been left to grow taller. If the sucker higher than a hand height, I use more kero. This method is easy.and wont harm the Mother plant
