    Fast facts about thuja Green Giant

    Growth habit:  --- If watering and fertilizing are maintained, Green Giant thuja can grow 3 ft or more each year, eventually reaching over 50-60 feet tall with a base measuring between 12-20' .  There are few trees that can grow that fast and still withstand high winds, heavy ice and snow loads.

    Hardiness and drought tolerance:   --- Once established, Green Giant thuja can withstand periods of drought, even thriving in the intense heat and humidity of Atlanta, Georgia. Best grown in zones 5-8.  

    Soil, water, light needs:   --- Thujas are highly adaptable, will grow in a wide range of soil conditions, and thrive in both sandy, and heavy clay garden soils. They need evenly moist soil, but cannot tolerate wet, soggy or water logged areas. Those living in warmer, southern planting zones, or those who have very sandy soils that tend to dry out quickly may choose to mulch in order to cool the soil, preserve moisture, and feed the trees. If you choose to mulch, never use more than 3 inches of mulch, keep mulch a few inches away from trunk to prevent rot, and never use plastic over the roots. Thuja love sun, and thrive best in full sun, but will grow in light shade, though the foliage will not be as dense, and the tree will not grow as tall.

    Pest & diseases info : --- Very robust and resistant to pests and diseases. Even bagworms leave it alone.  Deer generally leave it alone, but are known to nibble in areas where other browse is not available. No plant is deer proof if deer are plentiful and hungry. If you have problem with deer nibbling, you might want to purchase a product called Plantskydd, one of the most effective deer repellents we know of.  This will prevent the deer from continuing to feed.  Wait until spring to see if new growth breaks out. If not, you might need to replace the trees.

    How does it compare to other evergreens?  --- Green Giant arborvitae is more drought tolerant than Leyland cypress, and less prone to pests and disease than many other evergreens. Its disease resistance, adaptability, and dense foliage, make a great choice over other evergreens like hemlock and spruce in the North

    Pruning and shearing:--- If left unpruned, thuja Green Giant will form a graceful pyramidal shape 40 - 60 ft. tall, and foliage that stays dense all the way to the ground. Once established, they respond wonderfully to pruning in early summer (after they've had their spring flush). You can use a hedge sheer or trim by hand, but trimming by hand, particularly when cutting back the main leader, and the competing verticals will look more natural. The leaders on the young Green Giants tend to grow quickly, outpacing the main body of the tree, and can leave it looking leggy, so trimming back the leader by one third in late spring or early summer will encourage the plant to be more uniform and bushy. If you choose to shear your thuja into a hedge shape you'll be doing this 2-3 times from spring to midsummer. Prune off dead and broken growth with a hand pruners, then shear only the new growth back by about half. Make sure to water and fertilize to help the plant recover from shearing.

    Fertilizing:--- Like most evergreens, thuja do not need to be fertilized at planting time. Fertilizing each spring, once established is all that is needed. We use Osmocote Slow-Release Fertilizer, available at any good garden center. Top dress in spring as new growth is emerging; April 15, or "tax day" is a good reminder for annually fertilizing. This will feed your thuja for weeks & is needed only once per year.

    When to plant:

    Thuja can be planted in early spring or in fall, six to eight weeks before hard cold and frost set in, when the weather is cool.   You can continue to plant in early summer if you are in a northern climate, and weather remains cool. The most important thing is going into winter is that thuja are well hydrated. The cold isn’t the problem, lack of water is.  This is called winter burn.  Winter winds dry out the evergreen leaves so the outer few inches turn brown. In April, we recommend taking your hedge trimmers and removing the brown.  Thujas will put out new growth and be fine by the end of May. We’ve heard of mixed results with burlap.  If you elect to use them, avoid using any anti-desiccants. Never fertilize in fall, as it stimulates new growth that is more tender, and susceptible to winter damage.

    Planting - how to

    1. Once you have identified your planting location,
    2. Dig a hole twice as large & deep as your root ball
    3. Refer to spacing information below
    4. Fill in hole with organic matter. This helps to get your plants off to a good start.
    5. Remove thuja from plastic container and lightly loosen the roots. Place in the hole with fresh soil and tap down the soil so plant is set firm and there is no gaps in the soil. Make sure the top of the root ball is flush with the soil line – not above or below it.
    6. Provide up to an inch of water a week for newly planted thujas.

    Plant spacing

    Thujas can be planted in single or staggered rows. Depending on desired effect, space Thuja 5-8 feet apart

    Single row spacing

     XXXXXXX --- Thuja Green Giant spaced 5 feet apart in a single row

    Staggered row spacing

    For extra privacy or noise abatement, plant Thuja not in one straight line but a double row alternating the placement as in this diagram planting 10 feet apart.  It is tempting to go closer to get very fast coverage, but since Thujas can grow three feet a year try to be a little more patient. You’ll be rewarded because mature plants will be spaced perfectly.

    Planting FAQ

    Can I plant near old hardwoods? If you can keep them adequately moist during their first 1-2 years of establishment, you'll be fine. They would need a good soaking every week during the spring & hot summer months

    How close to a building can I plant?  You should plant at least 8 feet away from any building structure

    Is Thuja salt tolerant?  No, Thuja is salt sensitive. It can however, withstand heavy ice or snow loads.

    I just planted my Thujas in spring and have not seen any summer growth, why?  Plants are busy “putting their roots down” so to speak.  The good stuff is happening beneath the soil, where the plants are establishing themselves in their new environment.  Depending on conditions, you might see growth spurts by fall, or definitely by the following year.

    Need something shorter?  Consider Thuja Emerald which grows only 7-8 feet tall. Leyland cypress, thuja Wintergreen are other excellent hedge plants.  Other considerations (not evergreen) include ornamental grasses, burning bush, or hydrangeas.

    Soil: Best grown in moist, fertile, well-drained soils. Tolerates somewhat wide range of soils and some dry conditions. Poorly drained and wet sites should be avoided, and it is very salt-sensitive.
    Light: Full sun (6 hrs direct light daily), Partial sun/shade (4-6 hrs light daily)
    Water: Keep moist. Water 1 inch a week. Appreciates well-drained soil.
    Spacing: 3 - 5 ft
    Fertilizing: Top dress in spring with a slow release, balanced fertilizer.
    Winterizing: Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder zones. Tolerates wind once established and withstands heavy ice or snow. Darkens or bronzes slightly in the winter. Note -- The oldest, interior branchlets on an arborvitae normally turn brown and fall off in autumn. This aging process is different from drought stress, which on arborvitae appears on the tree outside the interior foliage as an abnormal yellowing or browning, known as flagging. This discoloration may not appear until a season or two after the drought stress was most severe.
    Maintenance & pruning: Requires little or no pruning but can be sheared easily if necessary. When pruning is necessary, it is recommended to only trim back the new growth of the current season, other than to remove any die back.

    I have to say the plants are fantastic! I was kind of leary, because others advertise quart plants and their idea of quart plants is not mine. But these plants were gorgeous, and well worth the money. I will tell my friends about you and will order again.
