I planted 8 acmena smithii (neighbors be gone variety) Lilly Pillies across the fence last year for privacy because they're marketed as fast growing and being tolerant of neglect/hard prune.

They're 100% healthy and fed with seasol/powerfeed regularly but barely grown up at all which is so frustrating, almost want to rip them all out and replace it with something else.

I wonder if this is normal or should they have put more growth in their second year?
