Example Calculation
Brussels Sprouts Seedling Planting
Row length: 100 inches
Seedling spacing: 18 inches
Number of rows: 3
Calculation
Seedlings per row = floor(100 ÷ 18) = floor(5.56) = 5
Total seedlings = 5 × 3 = 15 Brussels sprouts seedlings
Garden dimensions = 8.3 ft × 3.5 ft = 29.1 sq ft

Understanding Vegetable Seed Spacing
Why Proper Spacing Matters
Proper spacing ensures each plant has adequate room for root development, air circulation, and access to sunlight and nutrients. Overcrowded plants compete for resources and are more susceptible to diseases.
Benefits of Correct Spacing:
- • Better air circulation reduces disease risk
- • Adequate nutrients for each plant
- • Easier cultivation and harvesting
- • Higher yields and better quality produce
Seeds vs. Seedlings
Direct Seeding
Planting seeds directly in the garden. Best for hardy vegetables like beans, corn, and carrots.
Transplanting
Starting seeds indoors and transplanting. Required for tender crops like tomatoes and peppers.
Garden Planning Tips
Succession Planting
Plant the same crop every 2-3 weeks for continuous harvest throughout the growing season.
Companion Planting
Plant compatible vegetables together to maximize space and improve growth conditions.
Row Orientation
Orient rows north-south when possible to ensure even sunlight exposure for all plants.
Transplanting Guidelines
Best Conditions for Transplanting
- • Cloudy or drizzly weather
- • Late afternoon to reduce stress
- • Soil temperature appropriate for the crop
- • After hardening off seedlings
Transplanting Tips
- • Prepare planting holes in advance
- • Keep root ball intact when possible
- • Water immediately after transplanting
- • Provide shade for first few days if needed
