Residential and commercial landscaping can be a profitable business. Lawns need routine maintenance to stay healthy and look vibrant, which is where a landscaping spray business comes in. Landscaping professionals apply pesticides and other chemicals to help keep a lawn looking its best. Many states, including Ohio, require any landscaper to be licensed before he can work on any properties due to the potentially hazardous nature of the chemicals used in landscaping spray.
