How Do You Plant Arborvitae – For A Lush, Long-Lasting Privacy Screen
To plant arborvitae successfully, dig a hole twice as wide as the root ball but no deeper than the container. Position the tree so the top of the root flare sits slightly above the soil line, backfill with native soil, and apply a deep, thorough watering to eliminate air pockets.
You want a lush, green privacy wall that stands the test of time, but you aren’t sure where to start. Many homeowners struggle with trees that yellow or fail to thrive simply because they didn’t get the basics right during the first hour in the ground.
I have spent years helping gardeners transform barren property lines into vibrant, emerald screens. When you learn exactly how do you plant arborvitae using professional techniques, you ensure your investment grows healthy and strong for years to come.
In this guide, I will walk you through the entire process, from selecting the right cultivar for your zone to the critical aftercare steps that prevent common diseases. Let’s get your landscape looking exactly how you imagined.
Understanding the Basics: Why Choose Arborvitae?
Arborvitae—which translates to tree of life—are the gold standard for residential privacy. These evergreen conifers provide year-round density that effectively blocks wind, noise, and unwanted views.
Unlike deciduous trees that drop their leaves, these plants maintain their needles throughout the winter. They are versatile, hardy, and come in various shapes, from the towering Green Giant to the narrower Emerald Green.
Choosing the right variety is the first step toward success. Consider your space constraints and your local climate before heading to the nursery to ensure you aren’t fighting your landscape’s natural limitations.
How do you plant arborvitae: A Step-by-Step Guide
Planting is more than just digging a hole and dropping a tree in. It is a precise process that sets the stage for root development and long-term vitality.
Follow these professional steps to ensure your arborvitae starts with a competitive advantage against weeds and soil compaction.
1. Prepare the Site
Clear a three-foot diameter circle of all turfgrass and weeds. Competition for nutrients and water is the number one cause of stunted growth in young evergreens.
Test your soil drainage by digging a small hole and filling it with water. If the water sits for more than a few hours, you have heavy clay soil that may require soil amendment with organic compost to improve aeration.
2. Digging the Perfect Hole
Dig your hole twice as wide as the root ball. Width is far more important than depth for lateral root expansion.
Keep the hole shallow enough so that the top of the root ball sits about one to two inches above the surrounding soil surface. Planting too deep leads to root rot and bark decay.
3. Placement and Backfilling
Gently remove the plant from its container. If the roots are circling tightly, use your fingers to loosen them outward so they can grow into the surrounding soil.
Place the tree in the center of the hole. Backfill with the soil you excavated, gently tamping it down with your hands—not your feet—to avoid compacting the earth and suffocating the roots.
Essential Aftercare for Healthy Growth
The first growing season is the most critical period for your new trees. You must manage moisture carefully to help the roots establish themselves in their new environment.
Water your trees deeply once or twice a week, depending on the heat. Use a soaker hose at the base of the plant to ensure the water reaches deep into the root zone rather than just wetting the surface.
Apply two inches of organic mulch, such as shredded bark, around the base of the tree. Keep the mulch a few inches away from the trunk to prevent moisture buildup that invites fungal pathogens.
Common Pitfalls and Troubleshooting
Even expert gardeners run into issues. Being able to spot signs of stress early can save your arborvitae from permanent damage.
Yellowing needles often indicate overwatering or poor drainage. If you notice browning on the tips during the winter, it may be winter burn, caused by cold winds drying out the foliage faster than the roots can pull moisture from frozen ground.
Keep an eye out for pests like bagworms. These insects create small, cone-shaped nests out of foliage; if you see them, remove them by hand immediately to prevent a full-scale infestation.
Landscape Design Considerations
Think about the mature width of the cultivar you choose. Planting them too close together restricts airflow, which invites diseases like tip blight.
For a dense screen, space your trees roughly three to five feet apart, measuring from center to center. This allows each tree to grow into a full, rounded shape while still overlapping its neighbor to form a solid wall.
Always call your local utility company before you dig. Striking a water or gas line is a dangerous, expensive mistake that ruins a perfectly good weekend project.
Frequently Asked Questions
What is the best time of year to plant arborvitae?
The best time to plant is in the early spring or mid-autumn. These cooler seasons allow the roots to establish before the stress of summer heat or winter freeze.
Do I need to fertilize my new arborvitae?
Avoid heavy chemical fertilizers during the first year. Instead, focus on high-quality compost mixed into the backfill to provide slow-release nutrients that won’t burn sensitive new roots.
How do I know if my arborvitae is getting enough water?
Check the soil moisture by sticking your finger two inches into the ground near the base. If it feels dry, it is time to water; if it feels soggy, hold off to prevent root rot.
Why is my arborvitae turning brown in the center?
Interior browning is often normal shedding of old needles as the tree grows. However, if the browning spreads to the outer branches, it may indicate a lack of light or a fungal issue.
Conclusion
Planting arborvitae is a rewarding project that provides lasting privacy and natural beauty to your outdoor space. By focusing on proper hole depth, soil health, and consistent watering, you ensure your trees remain vibrant for years.
Remember that gardening is a process of patience and observation. Watch your trees closely during their first year, and don’t hesitate to adjust your watering schedule as the seasons change.
Now that you have the knowledge, it is time to head to the nursery and pick out your trees. Your perfect, green privacy wall starts with that first hole in the ground.
