Desing for little openings for veggies that really need sun, other annual openings can be shaded with good long term pioneer species scattered all over.
Place annual sytems as close to house as possible in good spot with water and protected from wind - if they don't exsist desing and implement them.
Also protect most of your fruit with windbreaks.
Start with swales for water catchment/wind protection/biomass production.
Plant mostly pioneers and year after year add fruit
trees and shrubs in protected areas.
