1. What are the main insects and diseases that appear on trees?
2. Have you ever built a multiplicative garden? If not yet, do you intend to do so? [I have no idea what a 'multiplicative garden' is.]
3. How do you design an orchard correctly?
4. How many kinds of propagation [?] are there for fruit trees? What is advantage of growing fruit trees by transplanting/grafting (?) over growing from seed/grafting(?)?


I am not a horticulturalist, but I think that some of your vocabulary is awry.
