I planted photinia hedge spring 2013. I probably plante half and then finished it 2 months or more later!! so the second half of the hedge didn’t get as good a start unfortunately. I have pruned it well twice yearly since to thicken it well. The good half is beautifully thick but the other half is weak and lower 🙁 I will feed it now with shrub feed but when pruning in April/may will i prune the weaker side harder to promote more vigorous growthwill it ever catch up??
