Residential Horticulture

We offer classes, workshops, clinics, and other learning opportunities to help residents care for their lawns and landscapes in an environmentally friendly way. Because many people in Orange County come from other parts of the country, sharing research‑based information from the University of Florida helps them learn how to garden successfully in Florida’s unique climate.

Water Your Lawn Wisely – Daylight Savings Time

When Daylight Savings Time begins, check your irrigation system:

  • You may water up to twice a week.
  • Make sure your system is working correctly.
  • Apply ¾–1 inch of water per week.
  • Check that your rain sensor is working.

Lawns only use the water they need — the rest is wasted. Avoid overwatering.

Find more information on managing irrigation, see Lawn Irrigation.

Community Garden

Community gardens give people a place to grow vegetables when they do not have space at home. They help families save money, eat fresh food, and learn gardening skills. Many groups want to start community gardens, but they often need help understanding the steps involved. UF/IFAS Extension Orange County is here to guide you through the process.

What is a Community Garden?

A community garden is a shared piece of land where people work together to grow plants and share the harvest. These gardens have a long history, including Liberty Gardens in World War I and Victory Gardens in World War II.

How to Get Started

Starting a community garden works best when you have a group of people who are truly interested and ready to help. Before you begin:

  1. Make sure you have a committed group of gardeners.

  2. Learn what is involved in running a community garden. The Community Garden Start‑Up Guide from the American Community Gardening Association is a great place to begin.

Contact Us for Guidance

Ready to get started? Contact UF/IFAS Extension Orange County. Our team can help you navigate the process, answer questions, and plan for long-term success.

We offer guidance on site selection, soil preparation, plant choices, irrigation, and ongoing garden maintenance to help your community garden thrive.

Extension Agents and Master Gardener Volunteers may also be available to visit your site during key stages of development to provide additional support.
