How To Make Green Giant Arborvitae Grow Fast

To make green giant arborvitae grow fast, you need to provide the right soil, sunlight, water, and nutrients from the very start.
 
If you want to make green giant arborvitae grow fast, it’s totally doable with a solid plan and a little patience.
 
Green giant arborvitae is famous for its rapid growth rate, often adding three to five feet per year once established.
 
But getting a green giant arborvitae to grow fast isn’t just about planting it and hoping for the best.
 
You need to set it up for success by choosing the ideal location, prepping the soil properly, and sticking to a consistent care routine.
 
In this post, we’ll break down exactly how to make green giant arborvitae grow fast, what conditions they love most, and the common pitfalls that slow them down.
 
Let’s dig in and get your green giants thriving.
 

How to Make Green Giant Arborvitae Grow Fast

The best way to make green giant arborvitae grow fast is to focus on the fundamentals that fuel rapid green giant arborvitae growth.
 
These evergreens are naturally vigorous, but they still need the right environment to hit their full speed.
 

1. Pick a Sunny, Well-Draining Spot

Green giant arborvitae grow fastest when they receive at least six to eight hours of direct sunlight daily.
 
Full sun is ideal for fast green giant arborvitae growth, though they’ll tolerate partial shade.
 
The soil should drain well because soggy roots can stunt growth and even kill the tree.
 
If your soil is heavy clay, consider amending it with compost or planting on a slight mound to improve drainage.
 

2. Space Them Properly for Root Expansion

Crowded roots will slow everything down, so give each tree enough room to spread out.
 
To make green giant arborvitae grow fast, space them at least five to six feet apart for a privacy hedge.
 
If you’re planting individual specimens, give them eight to ten feet of space on all sides.
 
This allows the root system to establish quickly and support rapid top growth above ground.
 

3. Prep the Soil with Organic Matter

These trees aren’t super picky about soil type, but they do best in loamy, slightly acidic soil.
 
Mix in two to three inches of compost or aged manure into the planting area to boost organic matter.
 
Good soil prep helps green giant arborvitae grow fast by providing steady nutrition and improving moisture retention.
 
A soil test can tell you if you need to adjust the pH, which should ideally be between 6.0 and 7.5.
 

Essential Care Tips for Green Giant Arborvitae Fast Growth

Once your green giants are in the ground, consistent care is what keeps them accelerating.
 
These simple practices will help you make green giant arborvitae grow fast and stay healthy.
 

1. Water Deeply and Consistently the First Year

Deep watering encourages roots to grow deep, which supports faster green giant arborvitae growth above ground.
 
During the first growing season, water your trees once or twice a week with about ten gallons per tree.
 
The goal is to keep the root zone consistently moist, not soaked, especially during dry spells.
 
After the first year, established trees are more drought-tolerant but still benefit from regular watering during hot months.
 

2. Fertilize in Early Spring and Late Summer

A balanced, slow-release fertilizer like a 10-10-10 formula works wonders for green giant arborvitae fast growth.
 
Apply it in early spring just before new growth starts, and again in late summer to support root development.
 
Avoid high-nitrogen fertilizers in fall because they can trigger tender new growth that might get damaged by frost.
 
Follow the package rates carefully, as over-fertilizing can burn roots and actually slow growth.
 

3. Mulch Around the Base to Retain Moisture

Spread a two- to three-inch layer of organic mulch like wood chips or shredded bark around the drip line.
 
Mulch helps soil stay cool and moist, suppresses weeds, and slowly adds nutrients as it breaks down.
 
Keep the mulch a few inches away from the trunk to prevent rot and pest issues.
 
This simple step is a powerful way to make green giant arborvitae grow fast without extra effort.
 

Common Mistakes That Slow Green Giant Arborvitae Growth

Even with good intentions, some common errors can stop green giant arborvitae from growing as fast as they should.
 
Avoid these mistakes if you want to make green giant arborvitae grow fast.
 

1. Overwatering or Underwatering

Too much water leads to root rot, while too little water causes stress and stunted growth.
 
Check the soil moisture by sticking your finger a few inches into the ground near the root zone.
 
If it feels dry, water deeply if it feels soggy, hold off until it dries out a bit.
 

2. Planting at the Wrong Time

Spring and early fall are the best seasons to plant green giant arborvitae for fast growth.
 
Planting in the heat of summer or just before a hard freeze can shock the tree and slow establishment.
 
If you want to make green giant arborvitae grow fast, time your planting when temperatures are mild and rainfall is consistent.
 

3. Pruning Too Aggressively

Green giant arborvitae rarely need pruning, and heavy cutting can reduce their natural growth rate.
 
Only trim dead, broken, or diseased branches, and never remove more than a third of the foliage.
 
Let the tree keep its natural shape for maximum green giant arborvitae fast growth.
 

4. Ignoring Pests and Diseases

Bagworms, spider mites, and root rot can all slow down or stop growth entirely.
 
Inspect your trees regularly for signs of trouble like browning foliage, webbing, or sticky residue.
 
Early treatment helps you make green giant arborvitae grow fast by keeping the tree healthy and stress-free.
 

So, How to Make Green Giant Arborvitae Grow Fast

To make green giant arborvitae grow fast, you need to combine the right planting conditions with consistent care throughout the year.
 
Start by choosing a sunny spot with well-draining soil and give each tree enough room to spread its roots.
 
Water deeply during the first year, fertilize in spring and late summer, and mulch to hold in moisture.
 
Avoid common mistakes like overwatering, planting at the wrong time, or pruning too aggressively.
 
If you follow these steps, you’ll see impressive green giant arborvitae fast growth that turns your landscape into a lush, private retreat.
 
Now get out there and help those green giants reach their full potential.
