Choosing the perfect arborvitae for your landscaping project requires understanding its mature size. A common question is: How tall is a 7-gallon arborvitae? The answer isn't a single number, as the height depends significantly on the type of arborvitae and its growing conditions. This guide will help you understand the typical size and factors influencing the growth of a 7-gallon arborvitae.
Understanding 7-Gallon Container Size
A 7-gallon container indicates the size of the root ball, not the plant's height. While a larger container generally suggests a more mature plant, it doesn't provide a precise height measurement. A 7-gallon arborvitae is likely between 2 and 4 feet tall, but this is just a rough estimate.
Factors Affecting Arborvitae Height
Several factors dramatically influence the height of your 7-gallon arborvitae:
-
Arborvitae Variety: Different arborvitae cultivars exhibit vastly different growth habits. Some, like the Emerald Green arborvitae, are known for their columnar shape and relatively slow growth, while others can be much taller and faster-growing. Researching the specific cultivar is crucial for accurate height prediction.
-
Growing Conditions: Sunlight, soil type, watering, and fertilization all play a role. Arborvitae thrive in full sun to partial shade with well-drained soil. Consistent watering and proper fertilization will encourage healthy growth. Neglecting these factors can result in stunted growth.
-
Planting Time and Technique: Planting your arborvitae at the right time of year and using proper planting techniques contributes to healthy establishment and faster growth.
Estimating Height Based on Common Arborvitae Varieties
Let's examine some popular 7-gallon arborvitae varieties and their potential heights:
1. Emerald Green Arborvitae
A 7-gallon Emerald Green is likely to be 2-3 feet tall, with a slow growth rate adding only a few inches per year. These are popular for hedges and screens due to their compact form.
2. Techny Arborvitae
Techny arborvitae, known for its wider, denser growth, might be slightly shorter or wider at 7 gallons, perhaps 2-3 feet tall, but eventually developing a more significant spread than the Emerald Green.
3. Columnar Arborvitae (e.g., 'Columnaris')
Columnar varieties grow taller and narrower than other types. A 7-gallon specimen could be 3-4 feet tall, maintaining a narrow profile.
Tips for Healthy Arborvitae Growth
To maximize your arborvitae's growth potential and ensure it reaches its expected height, consider these tips:
- Choose the right variety: Select a cultivar appropriate for your climate and desired size.
- Plant in well-drained soil: Avoid soggy conditions that can lead to root rot.
- Water regularly: Especially during dry spells, consistent watering is key.
- Fertilize annually: A balanced fertilizer will promote healthy growth.
- Prune as needed: Pruning can maintain shape and remove dead or damaged branches.
Remember: The height of a 7-gallon arborvitae is only a starting point. The ultimate size depends on the variety, your care, and growing conditions. Always check the specific cultivar information for more accurate height projections. By understanding these factors, you can choose and care for your arborvitae to achieve the desired size and beauty in your landscape.
