One of the most common questions landscapers ask is:
"How much should I charge to install plants?"
The answer starts with understanding how long it takes your crew to install plant material.
Many landscape contractors estimate planting jobs based on experience or intuition. While experience is valuable, using standardized production rates allows you to estimate jobs faster, price work more consistently, and improve profitability.
In this article, we'll show you a simple way to estimate plant installation labor using production units.
What Is a Plant Installation Unit?
A unit is simply a standard amount of labor assigned to a specific plant size.
For example:
1 unit = 1 hour
.50 unit = 30 minutes
.10 unit = 6 minutes
.05 unit = 3 minutes
To convert units into minutes, multiply by 60.
Example:
.05 × 60 = 3 minutes
This means a plant assigned a value of .05 units is expected to take approximately 3 minutes to install.
Using units creates consistency across estimates and helps contractors quickly calculate labor requirements.
Example Plant Installation Production Rates
The following production rates are examples and should be adjusted based on your crew, soil conditions, access, and project complexity.
Plant Size, Unit Value, Installation Time
4-inch Pot = .025 = 1.5 Minutes
1-Gallon = .05 = 3 Minutes
2-Gallon = .075 = 4.5 Minutes
5-Gallon = .10 = 6 Minutes
15-Gallon = .25 = 15 Minutes
24-Inch Box = .50 = 30 Minutes
Remember, these values are estimating tools. Your actual production rates may vary.
Example Landscape Installation
Let's assume a landscape plan includes:
20 One-Gallon Shrubs
10 Five-Gallon Shrubs
2 Fifteen-Gallon Accent Trees
Using the production rates above:
One-Gallon Shrubs
20 Plants × .05 Units = 1.00 Labor Hour
or
20 Plants × 3 Minutes = 60 Minutes
Five-Gallon Shrubs
10 Plants × .10 Units = 1.00 Labor Hour
or
10 Plants × 6 Minutes = 60 Minutes
Fifteen-Gallon Trees
2 Plants × .25 Units = .50 Labor Hours
or
2 Plants × 15 Minutes = 30 Minutes
Total Installation Time
One-Gallon Shrubs + Five-Gallon Shrubs + Fifteen-Gallon Shrubs = Total Time to Install
1.00 Hours + 1.00 Hours + .50 Hours = 2.50 Labor Hours
Your estimate would then use 2.50 labor hours to calculate labor costs.

Why Production Rates Matter
Production rates help landscapers:
Estimate jobs faster
Maintain consistent pricing
Improve profitability
Train estimators
Reduce guesswork
Rather than trying to determine labor from scratch every time, you can simply count plants and apply the appropriate unit values.
Don't Forget Material Markup
Installation labor is only part of the estimate.
Plant material should generally be marked up to account for:
Time spent sourcing material
Pickup and delivery
Warranty risk
Plant replacement
Inventory fluctuations
Administrative time
Many landscape companies use material markups between:
20%
30%
40%
The appropriate markup depends on your business model and market conditions.
Be Careful With Small Jobs
One of the biggest mistakes landscapers make is estimating only the installation time for small projects.
Imagine a customer wants:
Three 1-gallon shrubs
The installation time may only be:
3 Plants × 3 Minutes = 9 Minutes
However, your company still must:
Receive the call
Prepare the estimate
Purchase materials
Load the truck
Drive to the nursery
Deliver plants
Travel to the project
Complete cleanup
Return to the shop
The actual company time invested may be several hours.
Establish a Minimum Charge
Most successful landscape companies establish minimum charges for small projects.
Common examples include:
2-Hour Minimum
4-Hour Minimum
Half-Day Minimum
These minimums help recover costs associated with:
Truck expenses
Fuel
Equipment
Administrative time
Material procurement
Scheduling
Insurance
Travel time
Without minimum charges, many small projects become unprofitable even when the installation itself only takes a few minutes.
Turning Time Into Profit
Estimating plant installation is ultimately about turning production time into profitable work.
By assigning production units to plant sizes, landscapers can quickly determine labor requirements, build consistent estimates, and reduce the risk of underpricing projects.
The goal isn't simply to know how long planting takes.
The goal is to understand how labor, materials, travel, and minimum charges come together to create a profitable estimate.
The most successful landscape contractors don't guess at labor. They use systems and production rates that allow them to estimate confidently and consistently.
Because profitable landscape companies start with profitable estimates.
