10 Fast-Growing Vegetables to Kickstart Your Prepper Garden

When you're just starting a prepper garden—or you’re looking to get productive in a hurry—fast-growing vegetables are essential. These crops provide quick harvests, are generally easy to grow, and help build momentum in your food-growing efforts. Many can also be succession sown, giving you multiple harvests in a single season.

Below is a table showing 10 of the best fast-growing vegetables for UK gardens, with how long they take from sowing to harvest, how quickly they grow, and a realistic yield from a typical raised bed (2.4m x 1.2m).

Vegetable Days to Harvest Growth Speed Yield (2.4m x 1.2m Bed)
Radishes 20–30 days Very Fast 3–4kg
Spinach 30–45 days Fast 2–3kg (cut-and-come-again)
Lettuce 30–50 days Fast 2–3kg (succession sown)
Spring Onions 60 days Medium 1.5–2kg
Pak Choi 45–60 days Fast 3–4kg
Turnips 50–60 days Fast 4–5kg (roots + greens)
Beetroot 50–70 days Medium 4–5kg (roots + tops)
Kohlrabi 45–60 days Fast 3–4kg
Chard 50–60 days Medium 3–4kg (cut-and-come-again)
French Beans 50–60 days Fast 2.5–3kg

Most of these crops can be sown in succession for multiple harvests through the growing season. Focus on leafy greens and root crops early on, then rotate in beans and beets for continued yield. These quick wins are perfect for keeping a survival garden productive while your slower crops mature.
