    Before we begin, let me introduce myself. I am a Landscape Horticulturist with the National Gardening Association. I have got 20 years of experience in landscape horticulture, landscape architecture, and design. We were found in the 1973. We're a non-profit leader in plant based education with a mission to promote home, school, and community gardening as a means to renew and sustain the essential connections between people, plants, and the environments.

    Greenhouses open up a whole new world for you. It can help you extend the growing season and you can start seeds early in the spring, and when the weather warms, you'll be ready to transplant into your own garden. That will also help you save money as well. So let's get started.
