How do we find employees for such a seasonal job?

Landscaping is a very seasonal industry here in Colorado, and because of this, our staffing needs vary greatly throughout the year. The United States Government provides a visa program to help staff seasonal companies when American workers are not available to fill the positions. The program gives H-2B visas to applicants from outside of the United States who are willing and able to work for a season in the U.S. and then return to their home country during the off season. We have been using this program for the past several years, and each year we bring back many of the same employees.

We value all of the cultures that are represented in our company, and believe that each employee’s background adds value to our company environment. We do advertise these positions to American workers before receiving any visas. We work hard to ensure that both English and Spanish speaking employees feel welcome and valued, and we staff several bilingual employees to ensure that the language barrier will not cause any issues for our customers or their projects. All employees receive benefits and are treated with kindness and respect, regardless of where they originate from.


Green Gives Back

At Green Landscape Solutions we are committed to helping build a strong and vibrant community, not only where we work but also where we live. We want our community and the people in it to prosper. For that reason, we are a dedicated and longtime supporter of the Sister Carmen Community Center, a family resource center that offers comprehensive assistance to individuals and families in the areas of nutrition, healthy living, advocacy and children’s services.

So...what do our clients have to say?


Very rarely do you find a landscaping company that consistently delivers in the areas of design, costing, installation, and maintenance. We found that in Green and are very happy to partner with them on all our projects.


Green Landscape Solutions did a great job with the design and installation of the landscaping for the front yard of our new home. We live in Colorado but designed a French Country inspired home and wanted a landscape to match. Tom created a design with flowering scrubs and trees that had the look we wanted but that would thrive in the Colorado climate. His team installed the features, including a stone staircase, in a reasonable time and did a great job.
