Pine trees (Pinus species) are coniferous evergreens. They range from towering giants to small, dwarf trees. Some species make excellent wind or privacy screens. If you are planting more than one tree, you will need to space them for optimum health and growth.
There is no one ideal rule for spacing pine trees. It depends more on the use of the tree rather than the tree species itself. In general, most evergreen conifers, including pines, grow best if spaced between 6 and 12 feet apart. Trees spaced less than 6 feet apart will probably require thinning. Trees spaced further than 12 feet apart will require more effort in weed control. Space pine trees used for windbreaks 8 feet apart, with10 feet between each row.
The larger the species of pine, the bigger the spacing. Space pines that grow to great heights 12 feet apart. These include the White and Austrian pines, which can grow up to 60 feet tall. Mugo pines, on the other hand, reach a maximum height of only 10 feet and can be spaced 6 feet apart.
While spacing is important, it is also vital to choose the right location for your pine trees. Pine trees need full sunlight, save the White pine, which can grow in part shade. Mugo and Scotch pines grow well in sandy soils, while most other pines will thrive in windy, exposed areas.
