Easy Seed Sowing Schedule

The sowing instructions on seed packets tell us how many weeks before our average last frost date seeds should be started indoors. This can range from 3 to 12 weeks or more, depending on the plant type.

To keep it simple, I use this streamlined sowing system. The seeds are grouped by start times, in two-week intervals.

Sowing Groups

This includes veggies, herbs, fruits, perennials, and flowering annuals. You can print this chart with the free, printable seed sowing schedule (below).

Group 1: 12 weeks / 90 days before last frost
Group 2: 10 weeks / 75 days
Group 3: 8 weeks / 60 days
Group 4: 6 weeks / 45 days
Group 5: 4 weeks / 30 days

Here’s an example
My last frost is approximately May 15.

I start my slowest growing seeds (Group 1) in late February, 12 weeks before this. Then, every two weeks I start a new group until it’s outdoor planting time.

Seeds that do best with direct (outdoor) sowing go in after that. If I do not have a good spot in the garden for a plant, I put it in a container. That allows me to control both the soil and the light.
