Whether to direct sow seeds or start them indoors begins with where you live.
Recommendations for USDA Hardiness Zones 3 to 11
Direct sowing involves planting seeds directly into your garden beds, raised planters, or outdoor containers rather than starting them indoors under grow lights or in a greenhouse. This method works best for plants that do not transplant well, have fast germination rates, or require minimal handling to thrive. Lots of hardy vegetables, herbs, and flowers grow best when directly sown because they establish stronger root systems without the stress of being moved.
Understanding which seeds are ideal for direct sowing will help you make the best decisions for your growing success. Choosing the right planting method will help your seeds have their best start.
Zone-specific Notes: Zones 3-5 have a larger range of seeds that should be started indoors based on the shorter growing season. Zones 6-11 can sow more seeds outdoors, as they have a longer growing season.
You can easily find your growing hardiness zone by searching: USDA Hardiness Zone and your zip code.
