A few years ago I set Photinia Red Robin and Pink Marble hedge mix of 2:1 respectively. Unbeknownst to me, the Red Robin is a quicker grower and has crowded out the Pink Marble and as a result there are slight gaps where the Pink Marble is.Should I leave things as they are or should I replace the Pink Marble for Red Robin in the autumn? Is there anything you could suggest to help the current issue? Also, in your opinion which is the best fertilizer to use and when. (I used well-rotted horse mature spring 2014 and it seemed fine)
