Write down the list of plant-care services you will offer.
Detail what each service entails, including the amount of time needed. For example, if you are offering plant maintenance in a home, write down how much time you expect each visit to take.
Estimate your overhead, including travel costs, phone service, materials and equipment.
Call other plant-care services in your area. Find out what they charge. This will help you determine how much you will charge.
Calculate your hourly wage, based on what you want to make and your overhead. Compare this with what other businesses are charging. If the figure for your services is lower than what your competitors are charging, you're ahead of the game. If it isn't, consider how you can lower your overhead or your hourly rate or how you can make your service better than the competition.
Consider adding other services to your plant-care business, like pet care or house cleaning. Adding other services can help you enhance your bottom line. This is especially true if the need for plant care is limited in your area, but there's demand for something else.
