Vegetable Seed Calculator

The basic formula is: Seeds per row = Row length ÷ Seed spacing distance. Then multiply by the number of rows to get total seeds needed. For example, a 20-foot row with 6-inch spacing needs 40 seeds (240 inches ÷ 6 inches = 40).

Direct sowing works well for crops like beans, carrots, and corn that don't transplant easily. Transplanting is better for crops like tomatoes, peppers, and broccoli that benefit from a head start indoors. Consider your climate, growing season length, and the specific crop requirements.

Seed spacing varies by crop type. Small seeds like lettuce need 2-4 inches, medium crops like beets need 4-6 inches, and large plants like tomatoes need 12-24 inches. Always check your seed packet for specific recommendations as varieties can differ.

Yes, it's wise to plant 10-25% more seeds than calculated to account for poor germination, pest damage, or failed seedlings. Fresh, high-quality seeds typically have better germination rates than older seeds.

Prepare soil by removing weeds, adding compost or fertilizer, and tilling to 6-8 inches deep. Create straight, level rows using string lines or a hoe. Ensure proper drainage and that soil temperature is appropriate for your chosen crop.

Yes, select 'Transplant' as your planting method. The spacing for transplants is typically wider than for direct-sown seeds since you're planting established seedlings rather than seeds that may not all germinate.

The calculator supports both systems - U.S. measurements use feet and inches, while metric uses meters and centimeters. Choose the system you're most comfortable with; the calculations will be accurate for either.

The calculator estimates total garden area based on your row length and number of rows, assuming standard row spacing. This helps you plan your garden layout and determine if you have adequate space for your planned plantings.
