Is Now a Good Time to Plant?

Yes! Fall is one of the best times to plant!

Landscaping experts often recommend planting in fall instead of waiting until spring. Here’s why:

  • Cooler weather puts less stress on newly planted trees and shrubs.
  • Fall soil is still warm, which helps roots grow and get established.
  • Cooler temperatures mean less water is lost through the leaves, making it easier for plants to stay hydrated.
  • Even after top growth slows for winter, roots continue developing below ground.
  • Fall weather often brings more rain and less heat, making new plants easier to care for.
  • By spring, your plants already have a head start. Their established roots can support strong new leaves, branches, and flowers.
  • Trees planted in spring must establish their roots while also dealing with rising temperatures and summer heat.

Plant this fall, and your trees can spend the cooler months getting settled instead of waiting until spring to get started!

Planting your Thuja Green Giant Trees

Planting Guide for Thuja Green Giant

Choosing the Right Spot and Preparing the Soil:
The Thuja Green Giant performs best in full sun but also adapts well to partial shade, needing at least 4-6 hours of sunlight daily. It can grow in various soil types, yet it thrives in well-drained soil with a pH between 6.0-8.0. If your soil is heavy clay or overly compacted, mix in some organic compost to improve drainage. Avoid spots prone to standing water, as they can hinder root health.

Planting Your Thuja Green Giant:
Dig a hole that’s slightly shallower than the height of the root ball and about twice its width. This approach allows room for the roots to spread, with the root ball positioned slightly above ground level to avoid excess moisture pooling. Once positioned, backfill with soil, gently pressing down to remove any air pockets. Water deeply to help the soil settle. For privacy screens, plant each tree 5-8 feet apart for optimal growth.

Mulching Tips:
Spread a 2-3 inch layer of organic mulch, such as wood chips or bark, around the base of the tree. This layer helps retain soil moisture, regulates temperature, and minimizes weed growth. Keep mulch a few inches away from the trunk to reduce rot risk.

Care and Maintenance

Watering Needs:
In the first year, water your Thuja deeply every 5-7 days, especially during dry spells. Once established, these trees are drought-tolerant, though a deep watering every 10-14 days during prolonged dry periods will help maintain health.

Fertilizing:
Apply a balanced, slow-release fertilizer (such as a 10-10-10 formula) annually in early spring to support growth. Follow the product’s dosage recommendations based on tree size, and avoid over-fertilizing, which can encourage weak, excessive growth.

Pest and Disease Monitoring:
Though generally pest-resistant, Thuja Green Giants can occasionally attract spider mites, bagworms, or aphids. Regularly inspect the foliage and treat any pests with insecticidal soap or neem oil. Good air circulation around the tree can also help prevent fungal diseases.

Long-Term Care and Seasonal Tips

Pruning:
Thuja Green Giants require little pruning but can be shaped if needed. Light pruning in late winter or early spring helps maintain their size and encourages denser foliage. Avoid cutting back to old wood, as new growth won’t regenerate from these areas.

Winter Care and Extreme Conditions:
These trees withstand many climates but may need additional care in severe winter conditions. In snowy areas, loosely tie branches with twine to prevent damage from snow buildup. Thuja Green Giants are also naturally wind-resistant, making them effective windbreaks.

Preventing Root Issues:
To avoid root rot, ensure the soil drains well, and avoid overwatering. If fungal problems develop, trim affected areas and increase air circulation around the tree base.

By following these guidelines, your Thuja Green Giant will grow into a thriving, lush evergreen, perfect for adding privacy, acting as a windbreak, or enhancing your landscape with its greenery.

Beware- Not all Thujas are the Same!

Be sure to get Superior trees, grown by experts.

Better Roots Make Stronger Trees: Some nurseries send you "bare root" trees to save on shipping. Even worse, others have started digging them right out of the ground before shipping. This causes major transplant shock and long-term damage. We send you Thuja Green Giants in large, soil-filled containers- ensuring a well-developed root system that will explode with growth!

Healthy Plants: We've seen other nurseries grow tall Thujas in tiny pots to save on shipping. This leads to a "root bound" tree, where the roots have outgrown their pot- they cannot absorb water and nutrients. They quickly dry out during shipment, leading to an unhealthy tree.

Developed by arborists to be the perfect privacy tree. It quickly became a favorite across the country for its fast growth rate, drought tolerance and disease resistance. It practically thrives on neglect!

  •  The fastest growing evergreen you can find (up to 3-5 ft. per year)
  • Requires almost no maintenance- just plant it and forget it. No pruning and no spraying chemicals. Just add water!
  • Thrives in sandy soil, clay, or anything between. Even tolerates partial shade!
  •  Tough Trees: They withstand snow, ice, & deer!

Not all plants are created equal

The Difference Is in the Roots

Every plant we ship has grown in a nursery container with its roots protected, so it arrives healthy, established and ready to thrive in your yard.

Nationwide Plants compared with Other Nurseries
Nationwide Plants Other Nurseries
How it's grown Nationwide Plants: Grown in a nursery container, roots protected the whole time Other Nurseries: Pulled or dug from the field, tearing fragile roots
How it arrives Nationwide Plants: Arrives in its pot with soil intact Other Nurseries: Arrives bare root, exposed and drying out
Before shipping Nationwide Plants: Growing naturally until it ships Other Nurseries: Held dormant in a cooler, then shocked by a hot shipping box
Root health Nationwide Plants: Strong, well-developed roots with room to grow Other Nurseries: Crammed into a small pot until it's root bound
Height Nationwide Plants: Measured from the top of the soil Other Nurseries: Often includes the pot and roots
After planting Nationwide Plants: Settles in quickly with less transplant shock Other Nurseries: Arrives stressed and can take years to recover, if it does

The height you see is the height you plant.

We measure every plant from the top of the soil, not the bottom of the pot. Many nurseries include the pot and roots, so a "5–6 ft." tree from them might stand only 4 ft. tall once it's planted.

Comparisons reflect common practices across the online plant industry, not any single company.

Honest Measurements: Some nurseries measure trees including the pot and roots, so their "5-6 ft." tree may only be about three feet when planted. We measure all trees from the soil line, ensuring your tree reaches the promised height after planting.

From our nursery to your door

How We Ship Your Plants

Every order is hand-selected, watered and carefully packed so it arrives healthy and ready to plant. Here's what happens after you place your order.

  1. Step 1: Hand-Picked for You

    Our team selects the best plant available for your order. For privacy trees, that's the tallest and fullest. For fruit trees, it's the best branched.

    Why it matters: Many online nurseries ship whatever is next in the row.

  2. Step 2: A Deep Drink Before the Trip

    Every plant gets a thorough watering right before it's packed, so it starts the journey fully hydrated.

  3. Step 3: Roots Sealed In

    We wrap the pot and roots in plastic to lock in moisture, so your plant has water to drink all the way to your door.

    Why it matters: Bare-root plants are often shipped with their roots exposed and drying out.

  4. Step 4: Braced for the Ride

    Cardboard inserts are secured inside every box to hold your plant in place, so it won't slide, tip or get damaged in transit.

  5. Step 5: Shipped Only by FedEx

    We ship your trees exclusively with FedEx. We've found they deliver the fastest and handle live plants the most gently.

And if anything goes wrong, every plant is backed by our 1 Year Warranty.

Healthy Roots Make a Huge Difference

  • Never buy bare-root plants. These trees are starved of nutrients, and have a low survival rate.
  • Beware of nurseries cut corners by growing in small pots. These "rootbound" plants are weak, struggle to absorb nutrients, and die quickly after planting.
  • Some nurseries try to sell oversized plants, but chop off vital roots so they can cram the rootball into a narrow box to save on shipping!

Different Privacy Rows

Plant in a Row (straight line) to save space.

Row Planting Spacing Guide for Green Giant Thuja

How far apart do I plant my trees?

Plant as close as 5 feet apart for fastest privacy. Your trees will quickly grow into a dense, green wall, and reach a max height of 25 feet.

Plant as far apart as 10 feet if you're patient. Your trees will grow taller, but will take longer to block out unwanted sights.

Quality and Assurance with Nationwide Plants

Unlike bare-root options that carry a higher risk, Nationwide Plants offers potted, well-rooted Thuja trees that are prepared for immediate growth. Our trees are typically one to two years older than competitor Thujas, meaning they’re ready to establish themselves and grow quickly after planting.

Why Propagation Matters: Be cautious of seed-grown Thujas, which may not provide the same dense growth. Our Thuja Green Giants are meticulously selected hybrids, bred for resilience, fast growth, and full evergreen privacy.

Beautiful, Natural Privacy

Perfect for larger yards, the Thuja Green Giant reaches up to 30-50 feet in height and 10-15 feet in spread, forming a lush, green wall that adds privacy and aesthetic appeal. Its dense foliage also helps reduce noise, creating a tranquil space.

Year-Round Beauty: This evergreen keeps its deep green color through winter, enhancing your landscape every season.

Planting and Care Tips

For a seamless privacy hedge, plant 5-6 feet apart, or for a staggered, thicker screen, use an 8-10 feet spacing. The Thuja Green Giant is adaptable to various soil types, requires consistent watering while establishing, and performs best in full sun or partial shade.

The Nationwide Plants Difference

Frequently Asked Questions about the Thuja Green Giant Trees

How fast do Thuja Green Giant trees grow?

Thuja Green Giant trees are among the fastest-growing evergreens, growing 3 to 5 feet per year once established. Planting larger, well-rooted potted trees, like the soil-potted Thuja Green Giants from Nationwide Plants, helps them establish faster and form a full privacy screen sooner.

How tall and wide do Thuja Green Giants get?

At maturity, Thuja Green Giant trees reach 30 to 50 feet tall and 12 to 15 feet wide. Their dense, upright, pyramidal shape makes them ideal for tall privacy screens, windbreaks, and noise barriers in medium to large yards.

How far apart should I plant Thuja Green Giants for a privacy screen?

For a dense privacy hedge, plant Thuja Green Giants 5 to 6 feet apart in a single row. For a thicker, staggered privacy screen, use two offset rows with trees spaced 8 to 10 feet apart. Closer spacing creates privacy faster; wider spacing gives each tree more room to fill out.

What growing zones do Thuja Green Giants grow in?

Thuja Green Giant trees grow best in USDA hardiness zones 5 through 8. They tolerate cold winters, snow, ice, and summer heat, making them a reliable evergreen privacy tree across much of the United States.

How much sun does a Thuja Green Giant need?

Thuja Green Giants grow best in full sun but also tolerate partial shade. Plant them where they receive at least 4 to 6 hours of direct sunlight per day for the fastest growth and densest foliage.

How often should I water a newly planted Thuja Green Giant?

Water newly planted Thuja Green Giants deeply every 5 to 7 days during the first year, and more often during hot, dry weather. Once established, they are drought tolerant and only need a deep watering every 10 to 14 days during extended dry periods. Always plant in well-drained soil to prevent root rot.

What type of soil do Thuja Green Giants need?

Thuja Green Giants adapt to sandy soil, clay soil, and everything in between. They thrive in well-drained soil with a pH between 6.0 and 8.0. In heavy clay or compacted soil, mix in organic compost to improve drainage, and avoid areas where water pools.

Are Thuja Green Giants deer resistant?

Yes. Thuja Green Giant trees are deer resistant and much less likely to be browsed by deer than Emerald Green Arborvitae and other American arborvitae varieties. No plant is completely deer-proof when food is scarce, but Green Giants are one of the best low-maintenance privacy trees for areas with deer.

Do Thuja Green Giants stay green in winter?

Yes. Thuja Green Giant is an evergreen tree that keeps its rich green color through winter, providing year-round privacy. In areas with heavy snow, loosely tying the branches with twine can help prevent snow and ice damage.

Should I buy potted or bare root Thuja Green Giant trees?

Potted Thuja Green Giants are the better choice. Bare root trees ship without soil protecting the roots, which increases the risk of transplant shock and slow growth. Nationwide Plants ships well-rooted Thuja Green Giants in soil-filled containers, measured from the soil line up, so they are ready to establish quickly after planting.
