Plant Seeds

The "Plant Seeds" column references the frost date. Vegetables with "Before" can planted as soon as the soil is workable and can handle frost just fine. Vegetables with "At" should be planted around your frost date and can handle a light frost. Vegetables with "After" should be planted after the frost date since a frost will kill them

Veg Spacing

The "Veg Spacing" column of the When to Plant Vegetable Seeds table tells you how far apart you should plant the seeds in each row.

Row Spacing

The "Row Spacing" column tells you how far apart your rows should be from each other.

Thin Spacing

The "Thin Spacing" column tells you how far apart to thin the seedling too when they come up. Most thining is done after the plants are around 2-3" tall or have grown 3 true leaves.

Time to Harvest

The "Time to Harvest" column of the When to Plant Vegetable Seeds table shows the average time from planting to harvesting for that type of vegetable.

Succession Planting

The "Succession Planting" column refers to whether or not you should succession plant that vegetable. Succession planting ensures that you have a continual harvest throughout the growing season.
