Prepare the Landscape for Cedar Trees
A cedar tree grows quickly and can reach a width of 40 feet. By removing existing trees, shrubs, and grass from the area, cedars have less competition for nutrients. For optimal growth, you should remove branches and obstructions that create shade or select a different planting area. To ensure that roots have ample room to grow, clear an area at least as wide as the mature canopy size to give them space to expand.
When, Where, and How to Plant Cedar Trees
Once your land is thoroughly cleared, plant the cedar shrubs between spring and early fall in well-drained, fertile soil. It is important to plant all cedars in full sun. The location should receive six to eight hours of sunlight each day. The optimal soil for cedars is slightly acidic and moist. Place your cedars three to five feet apart, depending on the variety. You should place the crown of the plant several inches above soil level.
It is beneficial to apply fresh mulch every year, as it moderates root temperature and inhibits weed growth. Make sure to maintain a distance of at least three inches between the mulch and the trunks of the trees.
Fertilizing Your Cedar Trees
For successful cedar tree growth, fertilizing is a must. It will not only increase growth, but also create a positive impact on the health of your hedges. But if you plant cedars in the fall, avoid fertilizing them. During the autumn months, cedar trees are preparing to go dormant. Because of this, you shouldn’t promote their growth.
Pruning Cedar Trees
As with most conifers, cedars prosper from occasional, light pruning. To create a nice tight green hedge, prune the new green growth two to three times per year.
