After the second set of slots are placed, the slots are spaced on 15” centers so in real life planting, the furthest the plant will be from a slot would be 7.5”. In all but the most rugged conditions, the roots will find this path of least resistance and be able to penetrate deeper into the profile in search of moisture and nutrients.
