Watering frequency and duration for newly planted Green Giant arborvitae (Thuja standishii × plicata 'Green Giant') using drip irrigation will depend on various factors such as soil type, weather conditions, and the establishment of the plants. Here's a general guideline:
1. **Initial Watering:** Immediately after planting, thoroughly water the arborvitae to settle the soil around the roots. This initial watering helps eliminate air pockets and ensures good soil-to-root contact.
2. **Establishment Period (First Year):** During the first growing season, typically the first year after planting, it's crucial to keep the soil consistently moist but not waterlogged. Depending on your soil type and weather conditions, you may need to water every 2-3 days initially.
3. **Monitoring Soil Moisture:** Regularly monitor the soil moisture around the root zone of the arborvitae. Use a soil moisture meter or simply dig a small hole near the root ball to check soil moisture levels. The soil should be moist but not soggy.
4. **Adjusting Frequency:** As the plants establish and roots penetrate deeper into the soil, you can gradually reduce the frequency of watering. However, continue to monitor soil moisture and adjust watering as needed, especially during hot and dry periods.
5. **Duration of Watering:** When irrigating with drip irrigation, it's important to ensure that the water penetrates deep into the soil to encourage deep root growth. This may require watering for a longer duration but less frequently compared to shallow, frequent watering.
6. **Mulching:** Applying a layer of mulch around the base of the arborvitae helps retain soil moisture, regulate soil temperature, and suppress weed growth. Mulching can reduce the frequency of watering needed.
7. **Winter Watering:** In colder climates, continue to monitor soil moisture during the winter months, especially if there's insufficient rainfall or if the ground freezes and prevents moisture uptake. Watering during winter can help prevent desiccation of the plants.
8. **Observation:** Keep an eye on the health of the arborvitae. Signs of overwatering include yellowing or wilting foliage, while signs of underwatering include dry, brown foliage. Adjust your watering regimen accordingly based on the observed health of the plants.
Always consider local conditions and any specific recommendations from your nursery or gardening experts. Each garden and landscape can have unique requirements, so it's essential to adapt watering practices accordingly.
