How to Fertilize Arborvitae for Optimal Growth and Health
How to Fertilize Arborvitae?
To fertilize arborvitae, start by determining if the tree requires fertilizer.
Mature arborvitae trees planted alone usually do not need fertilizer, but if they are competing for nutrients or appear unhealthy, fertilizing may be necessary.
Use slow-release granular fertilizer with at least 50 percent nitrogen.
Apply the fertilizer evenly over the root zone and water it well afterwards.
Fertilize arborvitae during the growing season, with the first feeding before new growth begins and at intervals recommended on the fertilizer container.
Stop fertilizing one month before the first frost.
Newly planted arborvitae should not be fertilized, as it can damage the shallow root system.
Conduct a soil test to determine the pH and type of fertilizer needed.
Follow the instructions on the fertilizer label, and be sure to wear protective gloves and follow proper storage guidelines.

Did You Know?
1. Did you know that arborvitae, also known as the “tree of life,” is native to Eastern North America and was used by indigenous people for medicinal purposes?
2. In addition to being a popular landscaping plant, arborvitae has also been traditionally used in making canoes by Native American tribes due to its lightweight and water-resistant wood.
3. Arborvitae is a plant with deep cultural significance in China, where it is believed to bring good luck and symbolize longevity and friendship.
4. To help fertilize your arborvitae, try using a combination of organic matter such as compost or aged manure, alongside slow-release fertilizers that are high in nitrogen, phosphorus, and potassium.
5. When planting arborvitae, it is important to make sure they are properly spaced to allow sufficient air circulation, as overcrowding can lead to increased susceptibility to diseases and pests.
Arborvitae Trees And Nutrient Competition
In backyard environments where various plants compete for nutrients, arborvitae trees may require additional fertilization to ensure their optimal growth and health. These evergreen trees, known for their elegant and dense foliage, can often face competition from other plants, leading to nutrient deficiencies. However, it is important to note that mature arborvitae trees planted in isolation may not require fertilizer as they can access sufficient nutrients from the soil.
Fertilization Needs Of Mature Arborvitae Trees
Mature and established arborvitae trees may not need fertilization if they are healthy and not competing for nutrients. These trees can grow up to 60 feet tall and have a strong root system that can extract nutrients from the soil. Instead of relying on fertilizers, it is recommended to focus on maintaining a nutrient-rich soil during the planting process. A well-balanced soil composition will provide the necessary elements for growth, eliminating the need for additional fertilization.

Signs Of Unhealthy Arborvitae And The Need For Fertilization
If your arborvitae trees are struggling and showing signs of nutrient deficiency or general unhealthiness, fertilization may be necessary to revitalize their growth. Key signs to look out for include discolored or pale foliage, stunted growth, or the presence of dead or dying branches. Before proceeding with fertilization, it is crucial to identify the cause of the problem. Potential underlying issues to consider include poor drainage, insufficient watering, or pest infestation.
Recommended Fertilizer Type And Composition
When fertilizing arborvitae trees, selecting the appropriate fertilizer is crucial. Slow-release granular fertilizers are highly recommended for these evergreens because they provide a steady supply of nutrients over a longer period of time. Look for a fertilizer that contains at least 50 percent nitrogen, as this nutrient is essential for healthy foliage growth. Moreover, it is important to choose a fertilizer that is specifically designed for evergreen trees, as their nutrient requirements are different from those of acid-loving plants.
Proper Application Of Fertilizer For Arborvitae
To ensure the best results for your arborvitae trees, proper application of fertilizer is crucial:
- Distribute the granular fertilizer evenly over the root zone, which is the area underneath the canopy of the tree.
- Avoid applying the fertilizer directly against the trunk or foliage.
- Water the soil thoroughly after applying the fertilizer to help dissolve the granules and release nutrients.
- This watering also prevents the risk of root burn caused by concentrated fertilizer.
- Follow the instructions on the fertilizer label, as application rates may vary depending on the brand and concentration.
Remember, applying the fertilizer correctly and following the instructions provided are essential for optimal results.
Timing And Frequency Of Arborvitae Fertilization
Timing and frequency are key factors to consider when fertilizing arborvitae trees. The ideal time to fertilize is during the growing season, with the first feeding taking place before new growth begins. Follow the intervals recommended on the fertilizer container for subsequent applications.
To avoid subjecting the trees to frost damage, it is advisable to stop fertilization one month before the first frost in your region.
Remember that newly planted arborvitae trees should not be fertilized immediately, as this could harm their shallow root system. Instead, focus on providing them with nutrient-rich soil during the planting process.
Only once the trees are established and mature can you consider fertilizing to promote faster growth and stronger branches.
In conclusion, fertilizing arborvitae trees can be necessary to ensure their optimal growth and health, particularly in backyard environments where competition for nutrients is high. It is important to observe the trees’ appearance and address any signs of nutrient deficiencies or poor health. When applying fertilizer, choose a slow-release granular type with a suitable nitrogen content, and follow the instructions on the label for proper application. By fertilizing at the right time and frequency, you can support the growth and vitality of your arborvitae trees for years to come.

Frequently Asked Questions
How do you increase arborvitae growth?
To increase arborvitae growth, attention must be given to fertilizer. Although arborvitaes can flourish without fertilizer, promoting more vibrant foliage or expedited growth can be achieved by applying a nitrogen-rich, slow-release fertilizer annually in the spring. This strategic approach provides the necessary nutrients for the arborvitaes to thrive and reach their full potential. By stimulating their growth with the appropriate fertilizer, arborvitaes can transform into even more impressive and majestic additions to any landscape.
How do you revive an arborvitae tree?
Reviving an arborvitae tree can be a challenging task as there are limited options to encourage its recovery from browning. Patience is key, as you must wait and observe if the plant bounces back. However, if a significant portion of your arborvitae has died, it is unlikely to recover, and the best course of action might be to replace it with a new tree.
What is the best fertilizer to use on evergreen trees?
To ensure optimal growth and health of evergreen trees, the best fertilizer to use would be one with a balanced macronutrient ratio such as 10-8-15. This means that the fertilizer contains 10 percent nitrogen, 8 percent phosphorous, and 15 percent potassium. Nitrogen promotes lush foliage and vigorous growth, phosphorus stimulates root development and overall plant strength, and potassium boosts disease resistance and assists with water regulation. By providing these essential nutrients in a balanced form, the evergreen trees will receive the necessary elements for healthy growth and maintain their green foliage all year round.
How fast do arborvitae grow?
The growth rate of arborvitae, specifically the Emerald Green variety, is known to be relatively slow. On average, they grow less than a foot per year, with an annual growth rate of about 6-9 inches once they are fully established. It can take around 10-15 years for them to reach their mature height of 10 to 15 feet, while their spread at maturity is typically between 3-4 feet.
