Are you planting a garden this spring? Vegetable gardens are a great way to utilize space in your backyard. If you are new to vegetable gardening, you are probably wondering when you should start. Below, you will find a handy guide to help you understand when you should plant in your area of the country. When you start your plants, you can either start them indoors or use a cold frame greenhouse to start them outdoors. Cold frames act as a protective barrier, creating the perfect amount of sunlight and ventilation. This allows you to start your plants outdoors earlier than normal. Whether starting your gardening indoors or out, use the handy guide below to get started now!
Vegetable Growing Guide
You base when to start your plants (indoors or in a cold frame) on the date of the expected last frost in your growing zone. A “growing zone”, also known as a hardiness zone, is determined by the climatic conditions of the location where you live. It factors temperatures, rainfall, humidity, general soil conditions, and other factors to give your zone number. Your zone can also be used to help you determine which plants will thrive best where you live. The approximate date ranges for the last freeze in your zone is below.
- Zone 1 June 1 – June 30
- Zone 2 May 1 – May 31
- Zone 3 May 1 – May 31
- Zone 4 May 1 – May 31
- Zone 5 March 30 – April 30
- Zone 6 March 30 – April 30
- Zone 7 March 30 – April 30
