It is always prudent to plant regular trees in a straight line. Why this system works is because planting trees in a straight line ensures that as the trees grow up there is sufficient space for them to expand. A measured space between regular plants makes sure that each plant receives enough sunlight and nutrient and has a better chance of survival. Such an arrangement is also logical keeping in mind the future management of the plants when they grow up. Not only does the space come in handy while felling trees, it also makes the task of mowing easier.
