HAZELS
An experienced grower assures me it is a waste of time growing seedling hazels. Looking at the nut size of my seedlings compared to those of my named varieties, I am inclined to agree with her.
The other consideration with hazels is that they need a pollinator of a different variety that flowers at the right time so it does make sense to clone them so you know what you are getting.

Hazels are best multiplied by stools or air layering which is when branches are encouraged to root by pruning and covering with dirt, but they can also be propagated from cuttings.
Take cuttings of new growth no longer than 10cm. Lightly cut the bark on the bottom 2cm and soak in willow water or dip in rooting compound. Plant in a welldraining medium.
