Understanding the Importance of Planting Depth
Planting depth is more than just sticking a tree in the ground; it’s a fundamental factor in its future health. Planting too deep can suffocate the roots, hindering oxygen uptake and leading to root rot. Conversely, planting too shallow exposes the roots to drying out, temperature fluctuations, and potential damage.
For Emerald Green Arborvitae, getting the depth right is particularly important. Their shallow root systems are sensitive, making them vulnerable to improper planting. A properly planted tree establishes itself quickly and grows vigorously, while an improperly planted one struggles, becoming susceptible to diseases and pests.
Why Depth Matters for Arborvitae
The correct planting depth directly impacts several key aspects of an arborvitae’s development:
- Root Development: Proper depth encourages healthy root growth, allowing the tree to absorb water and nutrients efficiently.
- Oxygen Availability: Planting too deep restricts oxygen flow to the roots, which can lead to root rot and eventual tree death.
- Stability: A tree planted at the correct depth is more stable and less likely to be blown over by wind.
- Disease Resistance: Healthy trees are more resistant to diseases and pest infestations.
- Overall Vigor: Correct planting contributes to the tree’s overall health and vitality, leading to a more beautiful and long-lived specimen.
Understanding these factors highlights why knowing how deep to plant emerald green arborvitae is not just a suggestion, but a necessity for successful arborvitae cultivation.
Consequences of Incorrect Planting Depth
Failing to plant your Emerald Green Arborvitae at the correct depth can lead to a host of problems. Recognizing these potential issues is crucial for proactive care.
- Root Rot: This is a common and often fatal consequence of planting too deep. It occurs when the roots are deprived of oxygen and become infected by fungal pathogens.
- Poor Growth: Trees that are planted too deep or too shallow often exhibit stunted growth and reduced vigor.
- Yellowing Foliage: Chlorosis, or yellowing of the leaves, can be a sign of stress caused by improper planting depth.
- Reduced Drought Tolerance: Improperly planted trees are less efficient at absorbing water, making them more susceptible to drought stress.
- Increased Susceptibility to Pests and Diseases: Stressed trees are more vulnerable to infestations and infections.
- Tree Death: In severe cases, incorrect planting depth can ultimately lead to the death of the tree.
Avoiding these issues starts with knowing how deep to plant emerald green arborvitae.
Determining the Correct Planting Depth
The ideal planting depth for Emerald Green Arborvitae is crucial for its survival and growth. This section will guide you through the process of determining the correct depth, ensuring your trees thrive.
The Root Flare: Your Guide
The root flare is the most important indicator of planting depth. It’s the point where the trunk widens and transitions into the root system. This flare should be visible at or slightly above the soil surface after planting. The root flare is where the trunk meets the roots. This area should not be buried.
Before planting, carefully examine your Emerald Green Arborvitae. Locate the root flare. In some cases, nursery trees may have soil piled up around the base of the trunk, obscuring the root flare. Gently remove any excess soil to expose it.
Measuring the Depth
Once you’ve identified the root flare, you can determine the correct planting depth. The goal is to have the root flare level with, or slightly above, the surrounding soil.
- Container-Grown Trees: For container-grown trees, the root ball should be placed in the planting hole so that the top of the root ball is level with the existing soil grade.
- Balled and Burlapped (B&B) Trees: B&B trees should be planted with the top of the root ball slightly above the existing soil grade. This allows for settling.
Use a shovel or trowel to carefully measure the depth of the hole. The depth should match the height of the root ball, ensuring the root flare is at the appropriate level.
Specific Planting Depth Guidelines
The general rule is to plant Emerald Green Arborvitae so that the top of the root ball is level with, or slightly above, the existing soil grade. However, there are some nuances to consider:
- Slightly Above Grade: In heavy clay soils or areas with poor drainage, planting slightly above grade (1-2 inches) can help prevent root rot.
- Avoid Deep Planting: Never plant the tree deeper than it was in its original container or the nursery.
- Compaction: Be careful not to compact the soil around the root ball during backfilling.
Adhering to these guidelines ensures optimal growth and health for your trees.
Step-by-Step Planting Guide
Planting Emerald Green Arborvitae correctly involves several steps. Following this guide will help you create the ideal environment for your trees to thrive.
1. Site Selection and Preparation
Choose a location that receives at least 6 hours of sunlight daily, though they can tolerate partial shade. Emerald Green Arborvitae prefer well-draining soil. Before planting, test your soil’s drainage by digging a hole and filling it with water. If the water drains slowly, amend the soil with organic matter such as compost or well-rotted manure.

Consider the mature size of the trees when selecting a planting location. Emerald Green Arborvitae can grow to be 12-15 feet tall and 3-4 feet wide, so space them accordingly, or use the spacing recommended by the nursery. Ensure there are no underground utilities in the planting area.
2. Digging the Planting Hole
The planting hole should be wider than the root ball, but not necessarily deeper. Dig the hole twice as wide as the root ball to allow for root expansion. The depth should be the same as the height of the root ball, or slightly shallower, to accommodate the root flare.
Loosen the soil at the bottom and sides of the hole to encourage root growth. If you encounter compacted soil, use a garden fork to break it up. Avoid disturbing the soil directly beneath the root ball, as this can lead to settling.
3. Preparing the Arborvitae
Carefully remove the Emerald Green Arborvitae from its container. If the roots are circling, gently loosen them with your hands or a knife. For balled and burlapped trees, remove the burlap from the top of the root ball and cut away any twine.
Inspect the roots for any circling or girdling roots. Prune any damaged or circling roots to encourage healthy growth. Be gentle while handling the root ball to avoid damaging the delicate roots.
4. Planting the Arborvitae
Place the Emerald Green Arborvitae in the planting hole, ensuring the root flare is at or slightly above the soil surface. Backfill the hole with the original soil, amended with organic matter if needed. Gently tamp the soil around the root ball to eliminate air pockets.
Avoid burying the trunk or covering the root flare with soil. This is a common mistake that can lead to root rot. Make sure the tree is straight before filling the hole completely.
5. Watering and Mulching
Water the newly planted arborvitae thoroughly to settle the soil and provide moisture to the roots. Apply a 2-3 inch layer of mulch around the base of the tree, keeping it away from the trunk. Mulch helps retain moisture, suppress weeds, and regulate soil temperature.
Use an organic mulch like shredded bark or wood chips. Avoid using rocks or gravel as mulch. Water deeply and regularly, especially during the first growing season, to help the tree establish its roots.
6. Staking (if Necessary)
In windy areas, or if the tree is top-heavy, you may need to stake the Emerald Green Arborvitae for support. Use two stakes and flexible tree ties to secure the tree. The stakes should be positioned outside the root ball.
Ensure the ties are loose enough to allow for some movement, which helps the tree develop strong roots. Remove the stakes and ties after a year or when the tree is well-established.
Aftercare and Maintenance
Proper aftercare is crucial for the long-term health and vitality of your Emerald Green Arborvitae. Regular maintenance ensures your trees thrive.
