Ligustrum Waxleaf Privet – 20 Live Plants – Evergreen Privacy Hedge
This Ligustrum Waxleaf Privet stands out for its dense, glossy foliage and rapid growth, making it an excellent choice for quickly concealing an AC unit. Compared with the Thuja Green Giant options, it offers a more manageable height and easier pruning, though it may need more frequent watering and shearing to maintain shape. Its adaptability to various soil types and climates means it’s suitable for many gardens, but regular maintenance is necessary to keep it looking tidy. The plant’s fragrant white flowers add ornamental value, and its fast growth rate ensures swift coverage. However, it can grow quite tall without pruning and requires consistent watering until established. This pick makes the most sense for homeowners seeking a low-maintenance, dense hedge that can be shaped to fit smaller spaces.Pros:- Low-maintenance and easy to prune
- Dense foliage provides excellent privacy
- Thrives in various climates and soils
Cons:- Requires regular watering until established
- Can grow quite tall, needing frequent pruning

Waxleaf Privet – 30 Live Plants – Evergreen Privacy Hedge Shrub
This Waxleaf Privet is distinguished by its fast growth and versatile shaping potential, making it a strong candidate for quick concealment of an AC unit. Unlike the Ligustrum, it responds well to pruning for a more formal hedge or topiary, but it demands regular watering and mulching to thrive, especially during early growth. Its fragrant white blooms add ornamental interest, and it adapts to various landscape styles. While it’s less tolerant of drought once established, its rapid growth compensates for frequent watering needs. Compared with the Thuja Green Giant, it offers more flexibility in shaping but may require more ongoing care. This makes it suitable for homeowners who want a quick, customizable privacy barrier and are willing to maintain it regularly.Pros:- Fast-growing and easy to shape
- Produces attractive white fragrant blooms
- Responds well to pruning and shaping
Cons:- Requires regular watering and mulching
- Needs pruning 2-3 times annually to maintain shape
Best for: Gardeners seeking fast, easily shaped privacy options with ornamental appeal
Not ideal for: People with limited time for upkeep or those in drought-prone areas
- Sunlight Exposure:Full Sun
- Soil Type:Sandy Soil
- Moisture Needs:Regular Watering
- Item Weight:5 pounds
- Unit Count:30
- Number of Pieces:30
Our verdict“Best for those wanting a quick, shapable privacy hedge that can be tailored to their landscape style.”
Perfect Plants Thuja Green Giant Arborvitae, 1 Gallon, Privacy Trees
This Thuja Green Giant excels in quickly establishing tall privacy barriers, especially when compared with smaller plants like Podocarpus. Its dense, dark green foliage and pyramidal shape make it a classic choice for screening large areas, though its height of up to 60 feet can be a drawback in smaller yards. Once established, it requires minimal maintenance, but it demands space and pruning to keep it from outgrowing compact areas. Its adaptability to zones 5-9 and low-maintenance profile make it ideal for homeowners seeking instant privacy with minimal ongoing care, but it’s less suitable for those with limited space or seeking a shorter hedge.Pros:- Fast-growing—up to 3 feet per year
- Provides excellent, tall privacy
- Low maintenance once established
Cons:- Can grow very tall, requiring regular pruning
- Requires significant space for full maturity
Best for: Homeowners with large yards needing a fast-growing, tall privacy screen
Not ideal for: Small garden owners or those desiring a short, manageable hedge
- Size:1 Gallon
- Growth Rate:3-5 feet per year
- Mature Height:Up to 60 ft
- Mature Width:Up to 20 ft
- Zones:5-9
Our verdict“Ideal for large properties needing rapid, tall privacy, but unsuitable for small gardens due to its size.”
Perfect Plants Thuja Green Giant 3 Gallon Live Evergreen Tree for Landscaping & Privacy
This larger, 3-gallon Thuja Green Giant offers rapid growth of about 3 feet annually, making it suited for homeowners who want fast privacy in a single planting. It shares the same advantages as smaller Green Giants but provides a more mature look immediately. Its deer-resistant and drought-tolerant qualities add to its appeal, yet it cannot be shipped to California or Arizona, which limits availability. Its size—up to 40 feet tall—means it’s better suited for spacious yards or commercial landscapes, and it demands well-drained soil for optimal growth. Compared with the smaller 1-gallon version, this plant accelerates privacy establishment but requires more space and planning for proper placement.Pros:- Fast-growing—up to 3 feet annually
- Provides quick, tall privacy
- Deer-resistant and drought-tolerant
Cons:- Cannot be shipped to CA or AZ
- Requires well-drained soil for best results
Best for: Large yard owners wanting quick, tall privacy trees with minimal fuss
Not ideal for: Small garden enthusiasts or those in restricted zones where shipping is limited
- Growth Rate:3 feet per year
- Mature Size:40 feet tall, 20 feet wide
- Hardiness Zones:5-9
- Container Size:3 gallons
- Planting Time:Spring
Our verdict“A strong choice for large-scale privacy needs that prioritize fast growth and durability.”
Podocarpus Maki in 1 Gallon Pot – Evergreen Hedge Plant for Outdoor and Indoor Use
The Podocarpus Maki combines a refined, upright form with low maintenance needs, making it an attractive option for those seeking a neat barrier around an AC unit. Its dense, dark green foliage and upright habit create a polished appearance with minimal pruning, unlike the more flexible but less tidy Thuja Green Giant. It is drought-tolerant and resistant to pests, which reduces upkeep, but its height of 8-10 feet may be too large for tight spaces, and it requires full sun to partial shade for optimal growth. Compared with the Privets, it offers a more elegant, formal look but demands more sunlight and less adaptation to shady spots. This makes it ideal for homeowners wanting a clean, sophisticated hedge that requires minimal shaping.Pros:- Drought-tolerant and low maintenance
- Highly resistant to pests and diseases
- Polished columnar form requires minimal pruning
Cons:- Requires full sun to partial shade
- Grows up to 8-10 feet, which may be large for small gardens
Best for: Gardeners seeking a low-maintenance, elegant hedge in full sun to partial shade
Not ideal for: Those with shaded yards or limited space seeking a shorter or more flexible hedge
- Size:8–10 feet tall, 3–4 feet wide
- Growth habit:Upright, dense
- Foliage:Glossy dark green
- Zones:7–11
- Sunlight:Full sun to partial shade
- Maintenance:Low
Our verdict“Best suited for homeowners wanting a sleek, low-fuss hedge with a formal appearance in sunny locations.”
Thuja Green Giant | 10 Live Trees | Thuja standishii x plicata | Fast Growing Privacy Screen | Evergreen Landscape Plants for Borders
The Thuja Green Giant stands out as the top choice for those seeking a quick, reliable way to conceal an AC unit without constant upkeep. Compared with the Podocarpus Maki, which offers a more refined look, the Green Giant’s faster growth rate and dense foliage make it ideal for rapid screening. While it can grow quite large, requiring space and occasional pruning, its adaptability to various soils and low care needs make it suitable for most residential yards. However, the need for regular pruning to maintain a neat shape could be a downside for very low-maintenance gardeners. This pick makes the most sense for homeowners who need instant privacy with minimal fuss, but those with limited space should consider other options.
Pros:- Fast-growing, providing quick privacy coverage
- Evergreen foliage offers year-round concealment
- Easy to care for and adaptable to different soil types
Cons:- May require pruning to keep shape and prevent overgrowth
- Potentially large size that needs adequate space

- Species:Thuja standishii x plicata

Our verdict“This tree is perfect for those who prioritize rapid screening and low maintenance, provided there is enough space for its growth.”
How We Picked
I evaluated each plant based on growth speed, evergreen durability, maintenance requirements, and overall aesthetic appeal. Cost and availability also played a role, as well as how well each plant could fit into typical yard spaces around AC units. The ranking favors plants that balance privacy with ease of care, ensuring readers can find options suitable for both novice and experienced gardeners. Plants that grow quickly but demand high maintenance were placed lower, while those offering reliable year-round coverage with manageable upkeep ranked higher.Factors to Consider When Choosing Best Plants For Hiding AC Units
Choosing the best plants for hiding an AC unit requires considering several factors that influence long-term satisfaction and ease of care. The right plant should provide sufficient coverage, fit your climate, and match your maintenance capacity. Avoid common pitfalls like selecting overly large plants that outgrow your space or choosing species that require intensive upkeep. Here are key factors to weigh before making a decision.Growth Speed and Size
Fast-growing plants like Thuja Green Giant can quickly provide privacy, often within a single season, but they may need regular trimming to maintain desired shape and height. Conversely, slow growers save on maintenance but take longer to offer coverage, which might leave your AC exposed temporarily. Consider your patience and the available space—overly large plants can outgrow narrow spaces, while undersized plants may need years to fully hide your unit. Matching growth rate to your timeline and yard size is essential.
Evergreen vs. Deciduous
Evergreen plants maintain their foliage year-round, ensuring your AC remains concealed through all seasons. Deciduous options lose leaves in winter, which could temporarily expose your unit but often require less pruning and are typically less expensive. If year-round privacy is a priority, evergreen varieties like Privets or Thuja are better choices. However, deciduous plants might be suitable if you prefer a seasonal change or want to save on initial costs.
Maintenance and Care
Some plants, such as Privets, need regular pruning to keep their shape and height, especially in tight spaces. Others like Podocarpus Maki are relatively low-maintenance but may require occasional trimming and watering. Consider your gardening experience and willingness to care for the plants—choosing a low-maintenance species can reduce ongoing effort and expense. Also, check if the plant’s care needs match your local climate to avoid disappointment.
Climate Compatibility
Not all plants thrive in every climate—some are better suited for warmer zones, while others tolerate cold weather. Assess your USDA hardiness zone and choose accordingly; for instance, Thuja Green Giant performs well in a wide range of climates, making it versatile. Ignoring climate compatibility can lead to poor growth or plant failure, which defeats the purpose of a quick privacy solution.
Aesthetic Considerations
The visual impact matters—consider the plant’s foliage color, texture, and overall shape. Some plants like Privets offer dense, uniform coverage, creating a sleek privacy wall, while others like Podocarpus have a softer, more natural look. Think about how the plant will integrate into your landscaping style and whether you prefer a formal hedge or a more relaxed appearance.
Frequently Asked Questions
How tall should my plants be to effectively hide an AC unit?
The ideal height depends on your AC unit and yard layout, but generally, plants that reach 6 to 8 feet are sufficient for most standard units. Taller plants provide quicker coverage but may require more space and maintenance. If your yard is narrow, choose plants that grow vertically without spreading too wide, ensuring they don’t encroach on walkways or structures. Regular pruning can help maintain the height and shape to keep your AC hidden without overgrowth.
Can I plant these privacy plants in containers around my AC unit?
Many of these plants, like Podocarpus Maki, adapt well to container planting, which offers greater control over size and placement. Container planting can make maintenance easier and prevent overgrowth, especially in small yards or patios. However, container-grown plants may need more frequent watering and fertilizing, and selecting the right size container is crucial to support healthy growth. This approach is ideal for renters or those wanting flexibility in their landscape design.
Are there plants that can quickly recover if damaged or pruned excessively?
Fast-growing evergreens like Thuja Green Giant are resilient and tend to recover quickly from pruning or minor damage, making them suitable for areas where maintenance is frequent. Plants that can bounce back quickly reduce the risk of permanent damage and help maintain privacy. However, aggressive pruning should still be avoided to prevent stress or disease. Choosing hardy species helps ensure your privacy screen remains intact, even if you need to trim it regularly.
What’s the best way to plant these shrubs for quick coverage?
Planting these shrubs in clusters with proper spacing accelerates the formation of a dense hedge. Using high-quality soil and watering consistently in the first year supports healthy root development. Mulching around the base reduces weeds and retains moisture, helping plants establish faster. For instant privacy, consider planting more mature or larger specimens, which, although more expensive, provide immediate coverage and reduce waiting time.
How much maintenance should I expect to keep my plants looking good?
The level of maintenance varies: low-maintenance plants like Podocarpus Maki require minimal trimming once established, whereas Privets or Thuja Green Gaints need regular pruning to maintain shape and size. Expect to prune at least once or twice a year to keep plants healthy and looking tidy. Regular watering, fertilizing, and monitoring for pests are part of ongoing care. Proper initial planting and choosing the right species for your climate will reduce the amount of effort needed long-term.
