>A mature hazelnut tree produces enough calories for you to live an entire month. The cost? Less than a bag of hazelnuts.
do you have any idea how long it take for trees to produce their first nuts?
hazelnut will be around 5 years, almonds sometimes shorter sometimes longer, pistachio maybe 7 or so, walnuts can be 10 years or more.
lots of other crops to consider
