I attended Raintree Nursery's full day of classes workshop last weekend.
There are a lot of subjects covered by experienced people in the field,from pruning,propagating to Mason bee keeping.
The way they have it set up though,is there are two main areas or rooms and during each hour and a different subject is going on at the same time.A person has to make a choice and they don't repeat.This is my second time,so I've sampled almost all they offer.
When first reading the schedule,there was an hour devoted to a lady,Jo Robinson,who wrote a book,Eating on the Wild Side and no other class was going on then.I thought,I don't really want to go hear this lady talk about her dumb book,but I went anyway.It turned out to be probably the most enjoyable part of the class for me.
She said it took about ten years of research and reading over six thousand studies to put it together.Most of the talk covered how through cultivation,a lot of the beneficial properties of vegetables and fruits have been taken away.There were quite a few vegetables named,both very healthful and not so much,because on the way from harvest to market they lose much of their disease fighting abilities.There were enough fruits named,that I thought it may be of interest to some on this forum.
