Instructions How Far Apart to Plant Arborvitae Green Giant

Green Giant Arborvitae is popular because of their large size at maturity, attractive pyramidal forms, and slow growth rates. In addition, these evergreens are relatively low-maintenance plants that require little pruning to develop into a well-shaped specimen. Here we have provided some steps on how far apart to plant arborvitae green giant.

Step 1: Prepare The Planting Site

Remove organic matter, rocks, debris, and weeds from the planting site, till the soil to a depth of 8 to 10 inches in preparation for transplanting large plants like Arborvitae into the area. Early spring or fall is when you should perform this task.

Step 2: Remove Existing Vegetation

Remove existing vegetation by cutting the plants off at ground level or using a weed killer on unwanted grasses and weeds. A glyphosate-based herbicide is best for this application and will not harm desired plants like Arborvitae.

Step 3: Apply Fertilizer.

Apply a slow-release fertilizer with an adequate amount of nitrogen, phosphorus, and potassium at the rate of 1 pound per 100 square feet. Arborvitae green giant requires an application of 2 to 3 pounds of actual nitrogen each year for proper growth. This can be added in split applications throughout the growing season (early spring or late summer).

Step 4: Water

Water the land immediately after preparation is completed. This will encourage rooting into the soil and will help to reduce transplant shock. Water regularly for six weeks after planting to establish the root system in your yard.

Step 5: Mulch

Apply approximately 2 inches of mulch around trees, but keep it at least 4-inches away from the trunk of Arborvitae. This will help to retain moisture and keep weeds from growing around your plants.

Step 6: Regular Watering

Water trees regularly but do not over-water. Arborvitae green giant is a drought-resistant plant, and it takes water about one month to penetrate the soil to the roots of the tree. The amount of time needed to water arborvitae depends on weather and soil conditions.

They do not need to be watered every day, but weekly watering is required in some circumstances. Although deep watering once a week will benefit the plant, leaving the leaves wet overnight can result in fungal growth that could cause damage or even kill the tree.

Step 7: Trimming

After several years, make sure to trim back Arborvitae green giant once in a while because overgrown plants are challenging to maintain. In addition, overgrown Arborvitae is more susceptible to disease or further damage from harsh weather conditions.

Although these trees do not require much pruning, cutting the outer branches will help expose the tree to sunlight which will help it grow fuller.

Step 8: Pruning

Trimming and pruning is essential to caring for an arborvitae green giant. Ensure to prune in late winter or early spring since this is the only time the plant’s sap is not flowing. Never remove more than one-third of a tree in any year because it can weaken or even kill the tree.

Once you have mastered arborvitae pruning, there are several different ways to shape these plants and make them more appealing in your yard.

Step 9: Prune Branches

Remove any lower branches growing downward and cut the tips of the components to create a narrow, pyramidal shape. This is probably the most common way to prune arborvitae green giant because it creates a dense canopy with clean lines and makes attractive hedges.

Step 10: Topping

Topping an arborvitae green giant is not recommended because it can damage or kill the plant. You should never cut more than one-third of the tree in any given year, and you should not allow lower branches to grow unless you plan to prune them later on. Topping weakens trees, so try to do as little pruning as possible to maintain the health of your Arborvitae.
