Hose Watering Schedule (Good Drainage):
- Average temperature under 20°C: Water 1-2 times per week for approximately 2 minutes per tree in the morning.

Watering Disclaimer: Soil drainage greatly impacts watering needs. Adjust frequency based on soil moisture. Consistency is key; refrain from watering if soil remains moist. After the first season, reduce watering significantly, relying on natural rainfall once roots are established.
Pruning
Pruning plays a crucial role in maintaining the health and appearance of Emerald Green Arborvitae. Here's what you need to know:
- Transplant Shock: It's normal to observe brown patches a couple of weeks after transplanting. Simply prune off these affected areas to encourage new growth.
- Fall Maintenance: During fall, you may notice some brown internal foliage. This is part of the natural evergreen cycle as the tree prepares for new growth.
- Hedge Formation: To convert individual trees into a cohesive hedge, pruning is essential. Trim the tops of the trees to encourage lateral growth, resulting in a denser, wider hedge. Start by pruning the tops slightly shorter than desired height, gradually trimming until desired width is achieved. Regular trimming maintains the hedge's shape and density.
Winter Care
Emerald Green Arborvitae is hardy in cold climates, but a few precautions can help them thrive during winter:
- Burlap Protection (Optional): While not mandatory, wrapping trees in burlap can provide additional protection against harsh winter conditions, particularly for younger or newly planted specimens.
- Snow Load: Shake off heavy snow accumulation to prevent branches from bending or breaking under the weight.
Spring Maintenance
Spring is a critical time to promote healthy growth and vibrant foliage:
- Fertilization: Apply a high-nitrogen fertilizer in early spring to encourage lush green growth. Choose a fertilizer with a high first number (nitrogen content) to support vigorous foliage development. Water thoroughly after fertilizing to prevent root burn.
- Mulching: Apply a layer of organic mulch around the base of each tree to retain moisture, suppress weeds, and regulate soil temperature.
