Fertilizing and expected yield
Hello.
My grandfather has a house/orchard with many different fruit trees. Each year there is volatile yield, sometimes more sometimes less. I have started commiting more of my time both due to his age and due to me taking more and more interest in growing my own fruits.
My main question is, do you use store bought fertilizires and if so, how much ?
I ve tried searching for info on the internet, but most of it was for industrial scale plantations and intensive fruit farming. I dont need that , i just want healty trees , stable yield and quility fruit.
My plan , from what i have gathered for this year was : NPK 0-20-30 for grapevine , NPK 7-14-21 for adult fruit trees ( apple, pears, cherries, peaches, plums... ) and hommade compost for bushes ( redcurrant , blackberry ) and weak trees . I would be putting less then recommended dose for the first time.
Also, on the last pic, that branch should be prunned rught ? I ve checked and redcurrants werent prunned in two years, so there will be lots of work after the season and most branches are like that...
