Direct Sow vs Transplant
Which vegetables should you start indoors and which should go directly into the garden? A complete guide with a crop-by-crop breakdown.
Published November 15, 2025
The Core Rule
The decision of whether to transplant or direct sow comes down to one key question: Does this crop have a taproot that dislikes disturbance? Crops with taproots (carrots, beets, parsnips, turnips) should always be direct sown — transplanting damages the root and stunts the plant permanently. Crops that are fibrous-rooted (tomatoes, peppers, broccoli) handle transplanting well and benefit from the head start.
🏠 Always Transplant
Start indoors 6–10 weeks before last frost:
- • Tomato (7 wks)
- • Pepper (9 wks)
- • Eggplant (9 wks)
- • Onion (10 wks)
- • Leek (12 wks)
- • Celery (10 wks)
- • Broccoli (7 wks)
- • Cabbage (7 wks)
🌾 Always Direct Sow
Sow seeds directly where they'll grow:
- • Carrot
- • Radish
- • Beet
- • Parsnip
- • Turnip
- • Bush Bean / Pole Bean
- • Sweet Corn
- • Pea
- • Dill
- • Fennel
The In-Between Crops
Some crops can be transplanted OR direct sown. In short-season zones (3–5), it's better to transplant to extend the season. In long-season zones (7–11), direct sowing is often fine.
| Crop | Short Season (3–5) | Long Season (6–11) |
|---|---|---|
| Lettuce | Transplant (4–5 wks) | Direct sow outdoors |
| Cucumber | Transplant (3 wks) | Can direct sow |
| Squash | Transplant (3 wks) | Can direct sow |
| Swiss Chard | Transplant (4 wks) | Direct sow |
| Spinach | Direct sow ASAP | Direct sow |
| Melon | Transplant (4 wks) | Direct sow in warm soil |
