In an ideal situation, a tree with room to bloom will be planted. Therefore, the distance to the house should not be closer to half of its future length in its entirety. For example, 20 feet may still be too close for some large species of trees that grow more than 40 feet tall. Most landscape professionals recommend leaving at least 10 feet between small trees and at least 30 to 50 feet between large trees.
Medium-sized trees can grow well with a distance of 20 feet between them. So how far from the sidewalk should you plant a tree? The general rule is trees that grow to 30 feet (9 m). Trees that grow between 30 and 50 feet (9 to 15 m). Trees are usually separated according to the extent of their mature crown.
Spaces between trees of 50 to 60 feet are common places. This allows the open shape of the tree to develop (photo below). There are also beautiful examples of trees in urban and suburban landscapes spaced much closer together (photos above). The shape is very dominant and, therefore, these trees are best used as specimens or are clustered in massive plantations.
These trees also tend to develop a crown close to the ground, so pruning sessions need to be scheduled more frequently. The effect is also better when the trees are not planted directly in front of each other and are not of the same type. I would never recommend planting your trees 8″ from each other unless you're looking for a woodland look (even then a little more space), but some of these trees are planted very close. Keep in mind that this is simply a guide to give you an idea of how close the trees planted are to each other.
In addition, arbalists also believe that the roots of trees planted close to each other have a strong network that helps them communicate and care for themselves. Therefore, it's not a good idea from either perspective to plant shallow-rooted trees too close to sidewalks. Planting trees further apart allows them to conserve their natural way of growth, as seen in the upper left photo. Determining the correct space between trees is even more important when planting fruit trees.
Remember that while trees clustered too close together will provide shade, they will also prevent sunlight from reaching the lower leaves or smaller trees. Small trees can be planted less than 15 feet, but large trees should be planted 20 feet or more away from the house. Trees that grow aggressively, if planted too close to other trees or vegetation, could take up the space that other plants need. Front location If the house is positioned so that trees should be planted in the front for maximum shade, select trees that have tall branches so that outdoor areas can be seen under the branches.
This causes trees to grow taller faster and provide usable shade much earlier than a single planted tree would.
