How It Works
Select a vegetable from the list to see its recommended planting depth, spacing, and days to germination. A general rule is to plant seeds 2-3 times as deep as the seed is wide.
Formula
Planting Depth = 2-3x the seed diameter
Frequently Asked Questions
How deep should I plant seeds?
The general rule is to plant seeds at a depth of 2-3 times the seed diameter. Small seeds like lettuce and carrots need just 1/4 inch. Large seeds like beans and corn go 1-2 inches deep.
What happens if seeds are planted too deep?
Seeds planted too deep may exhaust their energy reserves before reaching the soil surface. They may fail to germinate or produce weak seedlings.
