Emerald cedars (Thuja occidentalis 'Smaragd') are a popular choice for homeowners in Ontario looking to create privacy screens, windbreaks, or add greenery to their landscapes. These evergreen beauties thrive in the Ontario climate but require consistent and proper watering to establish healthy roots and maintain their lush appearance. In this detailed guide, we will discuss the essential aspects of watering emerald cedars in Ontario, taking into account soil conditions, temperature, and drainage factors. Let's dive in and ensure your emerald cedars flourish!
Understanding the Importance of Proper Watering:
After planting emerald cedars, the first summer is a critical period when consistent watering is essential. This initial phase allows the young trees to establish their roots firmly in the soil, setting the stage for a long and healthy life. Even though emerald cedars can eventually rely on general rainfall once established, regular watering remains a good practice to ensure their vitality.
Soil Considerations:
The soil conditions in Ontario can vary significantly, which means your watering schedule should be tailored to your specific situation. Emerald cedars do not tolerate standing water well, so if you notice poor drainage, adjustments may be necessary to improve it. Proper soil drainage is vital to prevent root rot and other moisture-related issues.
Watering Schedule Based on Soil Drainage:
-
Drip Line Water Schedule (Good Drainage in the Soil):
- Average Temperature under 20°C: Water 1-2 times per week for approximately 2-3 hours in the morning.
- Average Temperature between 20-25°C: Water every other day for approximately 2-3 hours in the morning.
- Average Temperature over 25°C: Water every day for approximately 2-3 hours in the morning.
-
Hose Watering Schedule (Good Drainage in the Soil):
- Average Temperature under 20°C: Water 1-2 times per week for approximately 2 minutes per tree in the morning.
- Average Temperature between 20-25°C: Water every other day for approximately 2 minutes per tree in the morning.
- Average Temperature over 25°C: Water every day for approximately 2 minutes per tree in the morning.
Watering Disclaimer:
It's crucial to emphasize that your watering frequency may need adjustment depending on your soil drainage. To determine when your emerald cedars need watering, regularly check the soil's moisture level. If the soil remains moist, refrain from watering on that day. Consistent watering is the key to your tree's health and vitality.
Tips for Successful Watering:
-
Mulch: Applying a layer of mulch around the base of your emerald cedars helps retain moisture, regulate soil temperature, and prevent weed growth. Aim for a 2-3 inch layer of organic mulch, such as wood chips or bark.
-
Watering Technique: When watering, aim to soak the soil around the drip line of the tree. This encourages deep root growth and resilience against drought conditions.
-
Morning Watering: It's best to water your emerald cedars in the morning to allow time for the foliage to dry during the day. Wet foliage at night can increase the risk of diseases.
Maintaining a consistent and appropriate watering schedule is crucial for the health and longevity of your emerald cedars in Ontario. By understanding the soil conditions, considering temperature variations, and monitoring soil moisture, you can ensure your cedars thrive and provide the beauty and privacy you desire in your landscape. Follow these guidelines, and your emerald cedars will be a stunning addition to your outdoor space for years to come.
