Understanding sunlight exposure in gardening is vital for plant health and productivity. Terms like full sun, partial sun, and shade help gardeners choose suitable plants for their growing conditions. To provide clarity, we’ve adopted precise definitions from Penn State Extension to guide you in assessing sunlight exposure in your garden.

Full Sun:

  • Receives six or more hours of direct sunlight daily.
  • Sunlight may be continuous or split throughout the day.
  • Example: Four hours in the morning and three or four hours in the afternoon.

Partial Sun:

  • Gets four to six hours of direct sunlight daily.
  • Sunlight exposure typically occurs in either the morning or the afternoon.
  • Suitable for plants that thrive with intermittent sunlight exposure.

Partial Shade:

  • Receives two to four hours of direct sunlight daily.
  • Sunlight exposure often occurs during cooler parts of the morning or late afternoon.
  • Areas are sheltered from intense midday sun, ideal for plants requiring cooler light conditions.

Shade:

  • Gets less than two hours of direct sunlight daily.
  • Mostly experiences filtered light during daylight hours.
  • Suitable for plants that thrive without direct sun exposure and require protection from intense sunlight.

Understanding these definitions is crucial when selecting plants for your garden. Here’s a chart illustrating the sunlight requirements of various vegetables:
