Seed Starting and Planting Date Calculator for Cleveland, OH

Find the best dates for planting and transplanting vegetables and fruit in your garden! Our free planting calendar calculates the best time to start seeds indoors and outdoors, and when to plant young plants outside. Planting dates are based on frost dates, which are customized to your location and planting zone.

Frost dates are calculated from historical climate data and are a good way to know when it's "typical" to start planting in your area. However, they are not a replacement for good judgment! Obviously, you need to be aware of local weather during the gardening season and plant accordingly. Other factors that can influence your planting dates include soil temperature, altitude and slope of land, nearby waters, and day length. Also, it's recommended that you keep records of your garden's conditions each year to plan more accurately in the future.

On the chart below, please note:

  • "Start Seeds Indoors" tells you the optimal time to start vegetable and fruit seeds indoors. Learn how to start seeds indoors here
  • "Transplant Seedlings" tells you when it's likely safe to start planting young plants outdoors. This includes plants grown from seeds at home and plants bought from a nursery.
  • "Start Seeds Outdoors" tells you the optimal time to start vegetable and fruit seeds outdoors. Some seeds should be sown directly in the garden, rather than started indoors or transplanted.
  • When no dates appear in the chart, that starting method is not recommended for that particular vegetable.
  • The Frost Dates list the favorable planting dates based on your area's frost dates. This is the system that most gardeners follow.
  • The Moon Dates list the favorable planting dates based on your area's frost dates and Moon phases. Planting by the Moon is a more traditional technique, but many gardeners still swear by it today.
