| Crop | Recommended spacing (in) | Yield range (lb/plant) | Notes |
|---|---|---|---|
| Tomato | 18 | 6–15 | Staked/trellised. Yield varies by variety. |
| Carrot | 3 | 0.1–0.3 | Deep, loose soil is key. |
| Zucchini | 24 | 8–25 | Space-hungry plant. |
| Garlic | 6 | 0.1–0.2 | One clove becomes one bulb. |
| Lettuce | 8 | 0.25–0.75 | Perfect for intensive beds. |
| Cucumber | 12 | 2–6 | Assumes trellised slicing cucumber. |
| Bell Pepper | 18 | 1.5–5 | Needs heat for best yield. |
| Eggplant | 18 | 3–8 | Requires long warm season. |
| Kale | 12 | 1–3 | Harvest outer leaves continuously. |
| Bush Beans | 4 | 0.5–1.2 | Quick crop, great for soil. |
| Onion | 4 | 0.3–0.7 | Space for bulb expansion. |
| Broccoli | 18 | 1–2 | Main head + side shoots. |
| Cabbage | 15 | 2–5 | Heavy feeder, needs moisture. |
| Spinach | 4 | 0.1–0.3 | Cool season crop. |
| Radish | 2 | 0.05–0.1 | Fastest harvest (25–30 days). |
| Strawberry | 12 | 0.5–1.5 | Perennial; yield peaks in year 2. |
| Potato | 12 | 1.5–4 | Hilling increases yield. |
| Peas | 3 | 0.2–0.6 | Needs trellis support. |
| Beet | 4 | 0.2–0.5 | Roots and greens are edible. |
| Swiss Chard | 10 | 1–3 | Extremely heat tolerant. |

FAQs
Are the yield numbers guaranteed?
No—PlantYields shows ranges only. Variety, nutrition, pests, irrigation, and season length can change real harvest.
Does spacing assume perfect square planting?
Yes. Plant counts use a simple grid floor(length_in / spacing) × floor(width_in / spacing) so you don’t overpack.
What if I want intensive spacing?
Switch the calculator to Custom spacing and enter your own inches.
Can I use this for containers?
You can, but container depth and nutrition often reduce yield vs. in-ground or deep raised beds.
