The Hetz Midget Arborvitae (Thuja occidentalis ‘Hetz Midget’) is a popular dwarf evergreen shrub known for its compact, rounded form and dense foliage. It provides year-round greenery, making it a versatile choice for various landscaping designs. Its appeal stems from its manageable size and classic evergreen appearance.
Hetz Midget Growth Characteristics
The Hetz Midget Arborvitae is a slow-growing evergreen, adding only a few inches annually. This slow growth rate means it requires minimal pruning to maintain its shape.
At maturity, it usually reaches 3 to 4 feet tall and 4 to 5 feet wide, though some sources indicate 2 to 3 feet. Its natural rounded habit generally maintains a neat form without significant intervention.
Influences on Growth
Sunlight exposure affects growth; it thrives in full sun (6+ hours daily) but tolerates partial shade. Full sun promotes denser foliage, though afternoon shade is beneficial in hotter climates to prevent stress.
Soil type and moisture are also important. It adapts to a range of soils but prefers moist, well-drained conditions. It tolerates various soil pH levels, from slightly acidic to neutral, and can grow in clay soils if well-draining. Consistent moisture is preferred; it does not tolerate excessively dry or windy sites. It is hardy in USDA zones 2-7 or 3-8, withstanding a wide range of winter temperatures.
Cultivating Healthy Growth
Proper planting techniques are important for establishing a healthy Hetz Midget Arborvitae. When planting, dig a hole twice as wide as the root ball and the same depth, ensuring the top of the root ball is level with the surrounding soil. Amending the native soil with compost can improve establishment, and mulching helps protect roots and retain moisture.
Water regularly, especially for young plants and during dry periods, to keep the soil consistently moist but not waterlogged. Water at the base of the plant to reduce the risk of fungal issues. While Hetz Midget Arborvitae generally does not require extensive fertilization, a balanced, slow-release fertilizer can be applied in early spring to encourage robust growth. Pruning is typically minimal due to its natural globe shape; light shearing can be done in late winter or early spring to maintain its form, but avoid cutting into older, bare wood.
Ideal Uses for Hetz Midget Arborvitae
The Hetz Midget Arborvitae’s compact size and slow growth rate make it well-suited for various landscape applications. Its rounded form is ideal for foundation plantings, providing a neat evergreen presence near structures. It is also a good choice for low hedges or borders, defining garden spaces without frequent trimming.
Its manageable dimensions allow for use in rock gardens, small spaces, and container gardening. In containers, it adds year-round texture to patios or entryways. Its low maintenance contributes to its appeal as a versatile plant for many garden designs.
