Summarize this article in one sentence.
In the early stages of your business, you will need to rely on small scale activities like fliers, or going door to door. Advertising using social media can also be a good, cheap way to get some early advertising through friends and other acquaintances. Utilize social media to find new customers. You can establish Facebook page showcasing your work, and use business networking sites like LinkedIn and Google Plus. Look for sites where people search for services, like Angie's List and Yelp, and encourage your customers to post reviews there. These can be local groups like the Chamber of Commerce, or larger trade organizations. Local business groups can keep you connected to local businesses that may need your landscaping expertise, or can provide additional services to your company. Regional and national trade organizations allow you to keep up to date with changes in the business, and can provide additional opportunities for education. Look for other kinds of design or installation you can do to expand your customer base. Continuing education courses that you take through maintaining your contractor license can be a good opportunity to learn new skills that your customers will want to take advantage of. One good niche to move into is "interior-scaping". There are opportunities available for businesses that can manage the greenery of indoor spaces, such as malls or office buildings. You will want to know the type of plants best suited to the environment and will be visually appealing with the building's design. There can be quite a bit of overlap in this kind of work with that of a more general interior decorator. To get bigger, you may consider branching out into more advanced projects through landscape architecture. If you don't have a bachelor's degree, you can get one in Landscape Architecture (BLA or BSLA). There are further programs for a Masters in Landscape Architecture (MLA), which will differ depending on your undergraduate degree. The American Society of Landscape Architecture has a listing of accredited schools, both in-person and online, where you can earn these degrees. There is an additional MA/MS in Landscape Architecture, but that degree is better suited for someone who wants to do research in the field, not be a professional. The toughest part about growing as a landscaping business is that you will not be able to do all of the design and landscaping work. Instead, you will need to rely on your employees to keep up the quality that attracted customers in the first place. Make sure your business has design and work processes in place for everyone to follow, and perhaps a designated management team to help carry them out. Find ways to keep the best employees. Landscaping and lawn care are high turnover businesses. You need to find ways to keep your best employees, as they provide additional skills that allow you to attract more customers, and may not be easily replaceable. Finding ways for them to stay with the company, while still having room to grow, will help maintain standards and quality.

Summary:
Advertise. Join business organizations. Add a new niche. Get a degree in landscape architecture. Develop processes to maintain quality.
