3 good wal­nut va­ri­eties for the or­chard

NZ Lifestyle Block - - Self- Sufficiency -

Wal­nuts like a dry cli­mate, with a high sum­mer tem­per­a­ture and win­ter chill­ing (down to -10°C). Late spring frosts can be a prob­lem for some cul­ti­vars. Wal­nuts will grow in hu­mid ar­eas but there is more risk of dis­ease. Grafted trees are more ex­pen­sive to buy but will pro­duce nuts af­ter 3-5 years, vs 10-15 for seedling-grown trees.
