Single trees planted in pleasant spots are all around us. In the natural world, though, mosttrees aren't singles. They grow in clumps, groves, stands and forests.
Properly designed, a group planting allows each tree to thrive and share the availableresources.
One tree plopped down in a barren or competition-filled area, where the sun pounds down withlittle soil moisture to spare, is not a good idea.
A tree under these conditions has plenty of room to grow, but can only survive while gatheringessential resources and keeping pests at bay. New trees on new sites have a hard time.
Two trees planted together, where each can shade the other's stem and rooting area, can helpeach other grow. As long as the trees aren't jammed into a small pocket of soil, they can growtogether.
When putting two or more trees together, think first about the physical space available for atree to colonize.
Trees need space to grow into, both above and below the soil surface. The space a treecolonizes must contain, hold or produce enough essential resources to allow it to survive andgrow.
One key estimate of your site's tree-growth space is the soil surface area, in square feet, opento the atmosphere. The more square feet of open soil surface, the greater the chances ofgrowing great trees.
How much space do trees need to grow well? To find out, estimate the tree diameter someyears in the future. Figure the diameter (in inches) of a tree at 4.5 feet above the ground.Multiply that by 2.5 to get the critical rooting distance in feet.
The critical rooting distance is the minimum diameter of a circular area, with the tree in themiddle, you should preserve for the tree to use.
If you plant two trees together, add their CRDs. Then multiply the total by 0.6 (for 40 percentroot-system overlap) to get the CRD for both trees.
To calculate how much space you need to plant three, four or five trees together, add all theirCRDs. Then multiple that value by the allowed overlap values of 0.7 (three trees), 0.8 (fourtrees) or 0.9 (five trees).
No overlap is allowed with six or more trees. If you plant six or more together, use the totalCRD.
For boulevard, island or clump tree plantings, calculate the space you need. Be sure there areno soil limits. Trees can grow well together if you give them more than half a chance.

What makes trees strong? ›
All of the cellulose and lignin layers, closely packed together, create a very stiff cell wall unlike any other plant. It's the small changes to the structure of the cell wall, such as adding lignin and layers into the secondary wall, that make the difference in the structure between a flower cell and that of a tree.
As trees grow, they help stop climate change by removing carbon dioxide from the air, storing carbon in the trees and soil, and releasing oxygen into the atmosphere. Trees provide many benefits to us, every day.
Why should trees be planted close to each other? ›
Competition for sunlight is exactly why you plant them close together, to get a tall shady location. In reality the roots of many trees form a network where they can communicate, help each other fight diseases and pests, and benefit from biodiversity.
