Plant Spacing Guides
Get the spacing right for healthier plants and bigger harvests
Why Spacing Matters
Proper spacing ensures plants get enough:
- • Light - Crowded plants shade each other, reducing yields
- • Air circulation - Prevents fungal diseases
- • Water & nutrients - Roots don't have to compete
- • Room to grow - Plants reach full size and production

Spacing Methods
Row Planting
Traditional method with plants in rows. Good for large gardens and when you need to walk between rows or use machinery.
Square Foot Gardening
Divide beds into 1-foot squares. Each square gets a specific number of plants based on size. Maximizes space in raised beds.
Intensive/Block Planting
Plants spaced equidistantly in all directions (no rows). Creates living mulch, shades out weeds, and maximizes production per square foot.
Common Spacing Mistakes
Planting Too Close
Seedlings look tiny, but they grow! Overcrowding leads to stunted plants, poor air circulation, disease, and reduced yields. Always space for mature plant size.
Ignoring Variety Differences
A compact determinate tomato needs less space than an indeterminate variety. Check seed packets for variety-specific spacing recommendations.
Forgetting Vertical Growth
Trellised plants can be spaced closer together since they grow up, not out. Plan for your support system when determining spacing.
