# Raised Bed Vegetable Garden Layout: Maximum Yield Planning A well-planned raised bed vegetable garden can produce 2-3 times more food per square foot than traditional row gardening. The key is understanding spacing, companion planting, and succession strategies that keep your beds productive all season long. ## Why Raised Beds Produce More - **Intensive planting**: No wasted space between rows - **Better soil**: You control the growing medium - **Extended season**: Soil warms faster in spring - **Less compaction**: You never walk on growing soil - **Easier pest management**: Defined boundaries for covers and netting ## Standard Bed Dimensions | Size | Best For | Square Footage | |------|----------|----------------| | 4x4 ft | Beginners, children | 16 sq ft | | 4x8 ft | Most home gardens | 32 sq ft | | 4x12 ft | Serious growers | 48 sq ft | | 3x6 ft | Narrow spaces, accessibility | 18 sq ft | **Key rule**: Beds should be no wider than 4 feet so you can reach the center from either side. ## Soil Mix for Raised Beds The ideal raised bed soil mix (often called Mel's Mix): - **1/3 coarse vermiculite** (moisture retention) - **1/3 peat moss or coconut coir** (structure, water holding) - **1/3 blended compost** (nutrients, biology) ## Spacing Guide by Plant | Vegetable | Plants per sq ft | Depth | Days to Harvest | |-----------|-----------------|-------|-----------------| | Tomato | 1 per 2 sq ft | 1/4 inch | 60-85 | | Pepper | 1 | 1/4 inch | 60-90 | | Lettuce | 4 | 1/8 inch | 30-60 | | Carrot | 16 | 1/4 inch | 60-80 | | Radish | 16 | 1/2 inch | 25-35 | | Bush beans | 9 | 1 inch | 50-60 | | Spinach | 4-9 | 1/2 inch | 35-45 | | Cucumber | 1 per 2 sq ft | 1 inch | 50-70 | | Zucchini | 1 per 4 sq ft | 1 inch | 45-60 | | Garlic | 4-9 | 2 inch | 240 (overwinter) | ## Companion Planting Chart ### Good Companions | Plant | Friends | Why | |-------|---------|-----| | Tomato | Basil, carrot, parsley | Repels pests, improves flavor | | Pepper | Basil, carrot, onion | Shade and pest protection | | Bean | Corn, squash, carrot | Nitrogen fixation | | Lettuce | Radish, carrot, strawberry | Shade from taller plants | ### Bad Neighbors | Plant | Avoid | Why | |-------|-------|-----| | Tomato | Cabbage, fennel | Competition, allelopathy | | Bean | Onion, garlic | Inhibits growth | | Pepper | Fennel, kohlrabi | Stunts growth | | Cucumber | Potato, sage | Disease transfer | ## Succession Planting Strategy ### Spring (March-May) - Cool-season crops: lettuce, spinach, peas, radish - Start warm-season transplants indoors ### Summer (June-August) - Warm-season crops: tomato, pepper, beans, cucumber - Interplant quick crops between slower growers ### Fall (September-November) - Cool-season crops: kale, broccoli, garlic, arugula - Cover crops: clover, rye for soil improvement ## FAQ **Q: How deep should a raised bed be?** A: 12 inches minimum. 18 inches is ideal for deep-rooted crops like carrots and parsnips. **Q: Can I build raised beds on concrete?** A: Yes, but they need to be at least 18 inches deep with excellent drainage. ## Conclusion A well-planned raised bed layout transforms a small space into a productive food garden. Start with one 4x8 bed, follow the spacing and succession guidelines, and expand as your skills grow.
