Understanding the causes of arborvitae browning is just the first step toward preventing it. Regular inspection, maintenance, and care can go a long way in keeping your arborvitae healthy and beautiful.
Watering Techniques To Keep Your Arborvitae Healthy
Arborvitae, also known as white cedar, is a popular evergreen tree. It’s prized for its stunning foliage and its ability to provide a natural screen and privacy to gardens and yards. However, this tree is susceptible to turning brown, causing worry and stress for plant lovers.
We will focus on the watering techniques that can help keep your arborvitae healthy.
Deep Watering Vs. Light Watering
When it comes to watering your arborvitae, the method of watering is critical to its overall health. Deep watering and light watering are two methods that you can use to keep your arborvitae healthy.
Deep Watering
Deep watering is essential for the roots to grow healthy and strong. The process involves slowly and thoroughly watering the root zone of the arborvitae, allowing the water to penetrate deep into the soil. Here are a few things to remember:
- Water the tree slowly and deeply at least once per week.
- Ensure the water reaches at least 6 inches deep into the soil.
- Use a soaker hose or drip irrigation system to ensure deep watering.
Light Watering
Light watering is a process that involves watering the top layer of the soil around the tree. The method is suitable for newly planted trees. However, it’s not the best option for mature arborvitae. Here are a few things to remember:
- Water the tree in the early morning or evening to avoid water evaporation.
- Water the tree every other day for the first two weeks after planting.

When To Water
The timing of watering your arborvitae is critical to its growth and overall health. It’s always best to water your arborvitae early in the morning to maximize water absorption and reduce water loss through evaporation. Avoid watering the tree during the hottest part of the day, especially during summer.
Watering during this time can lead to fungal disease development.
How Much To Water
Overwatering and underwatering can both have adverse effects on your arborvitae. So, how much water does your tree need? The answer to this question is; it depends on the age and size of your tree. Use these guidelines to determine how much water your tree needs:
- Newly planted trees require 1-2 inches of water each week.
- During hot weather, increase the amount of water to 3-4 inches each week.
- Mature trees require 1 inch of water per week.
- For every inch of rain received during a week, reduce the amount of water you provide the tree by 1/3 inch.
Keeping your arborvitae healthy doesn’t have to be a complicated process. By using these watering techniques, you can help your tree grow healthy and strong. Remember to monitor your tree regularly for signs of browning, as this could indicate a more severe problem.

Identifying Early Signs Of Browning In Your Arborvitae
Arborvitae Are Turning Brown
Arborvitae, also known as white cedar, are popular evergreen shrubs and trees in North America. These plants are well-known for their beautiful foliage, which adds color and texture to any landscape. However, brown foliage can be alarming for homeowners with arborvitae in their gardens.
In this blog post, we aim to explain the early signs of browning in your arborvitae and how to identify and fix them.
Yellowing/Bronzing Of Foliage
Yellowing or bronzing of arborvitae foliage is an early sign of trouble. There are a few reasons why this may occur; some being:
- Overwatering the plants can cause the roots to rot, and the tree will lose its ability to absorb nutrients properly.
- Pests like spider mites, mites, and bagworms can disfigure the shrub, causing the foliage to turn yellow or bronze.
- The shrub is battling drought-like conditions and needs more water.
If yellowing or bronzing foliage is noticed, prune any affected branches or thirsty areas if it’s due to drought. Make sure to water the shrubs at the base of the plant. Further damage can be prevented by using an insecticide spray or miticide, depending on the presence of pests or mites.
