How old is a hazelnut tree before it bears fruit?

[Billy Reid S]

I planted about 30 hazelnut saplings 3 years ago against a very high south facing wall, can anyone tell me at what age they normally bear fruit?. They were 3 years old when I planted them.

Quote (from the Royal Horticultural Society's website);
"Cobnuts and filberts should start to produce nuts after three or four years".
