How-to Guide
How to Plan a Vegetable Garden (Beginner's Guide)
The short answer
Start by picking the sunniest spot you have — at least 6 hours of direct sun is the single biggest factor in vegetable success — and start small (a 4×8 foot bed is plenty for a beginner; you can always expand). Then sketch your beds on paper before planting: mark where each crop goes based on its MATURE size, not the tiny transplant.
Place the tallest crops (corn, trellised tomatoes, pole beans) on the north side so they don't shade shorter ones, put full-sun fruiting crops in the brightest spots and shade-tolerant greens where it's a bit dimmer, and leave 18-24 inch paths so you can work without trampling plants.
The planning steps
- 1Find full sun — Pick a spot with 6+ hours of direct sun; watch where shadows fall through the day.
- 2Start small — A 4×8 ft bed (or ~100 sq ft) is manageable for a first garden — better to succeed small than be overwhelmed.
- 3Sketch it on paper — Draw the beds and place each crop by its mature size; this prevents overcrowding you can't undo later.
- 4Arrange by height and sun — Tall crops to the north; sun-lovers (tomato, pepper, squash) in the brightest spots; greens/roots tolerate part shade.
- 5Leave working paths — 18-24 inch paths so you can reach every plant without stepping on the soil.
✔ Grow what you'll actually eat, and use crop rotation and succession planting from the start — see those guides. GardenSays' planting-date and spacing tools give you the exact numbers per crop.
