In 2014, we introduced Livermore Red Walnuts grafted seedlings from California, USA. In the next few years, we grafted Livermore Red Walnuts to Chinese local walnuts in our own walnuts garden, and developed China Red Walnuts variety successfully. Until now, we have about 1 million pcs of red walnuts grafted seedlings in our 80-hectare walnuts plantation. Among these red walnuts, about 5% of them are 5 years tree that have harvest of red walnuts of about 5000Kgs, 50% of them are 2~3 years with diameter of 25~35mm and height of 1.5~1.8m, and 30% of them are 1~2 years with diameter of 12~20mm and height of 0.5~1.2m, and the rest are newly grafted seedlings this year. According to our grafted seedlings marketing feedback, most of the 2~3 years red walnuts grafted seedlings will have harvest of red walnuts in the coming year, even some of them can have harvest of red walnuts the same year. While for 1~2 years red walnuts grafted seedlings, it takes at least 2 years to have harvest after planting. Unit now, we are the first one and maybe the only one to introduce the Livermore Red Walnuts, develop and plant large-scale in China, then we are called China Red Walnuts Planting Base.
