Service type: design and hardscape installation command far more than routine mowing and maintenance.
Seasonality: landscaping is a highly seasonal business in most climates, off-season planning and snow removal can help smooth revenue (see the seasonal revenue planner).
Equipment ownership: contractors with their own commercial-grade equipment can take on larger jobs and price accordingly.
Property size and access: large properties and difficult-access sites justify a premium over small, easy-access yards.
Starting out vs. established
New independent landscaper typically land near the $25/hr end while building a client base and reputation. Once you have proof of results and repeat or referred clients, the $40/hr median becomes realistic. Specialists with a strong track record and reputation routinely reach $85/hr or more.
