Growing fresh vegetables at home doesn't need to be a long-term commitment. Many gardeners don't realize that plenty of delicious veggies can go from seed to harvest in 30 to 45 days. This quick turnaround makes them perfect for impatient gardeners or anyone looking to maximize their growing season.
With these fast-maturing vegetables, you can enjoy homegrown produce in as little as a month. They're ideal for filling garden gaps, extending your harvest season, or getting kids excited about gardening with quick results.
1. Radishes (Raphanus sativus)
Radishes are the sprinters of the vegetable garden, often ready to harvest in just 21 to 30 days. These crisp, peppery roots come in a rainbow of colors from classic red to white, purple, and even watermelon-patterned varieties.
They're perfect for beginning gardeners because they germinate quickly and reliably. Sow radish seeds directly in the garden about 1/2 inch deep and 1 inch apart. Once seedlings emerge, thin them to 2 inches apart to give roots room to develop properly.
Radishes prefer cool weather and consistent moisture, making them ideal for spring and fall planting. For a continuous harvest, plant small batches every 7 to 10 days.
Radish Varieties for Quick Harvests
Cherry Belle radishes mature in just 22 days. They offer a classic round, red appearance with crisp white flesh. Their mild flavor makes them perfect for salads and garnishes.
French Breakfast radishes, ready in about 25 days, feature elongated roots with red tops and white tips. They offer a less pungent flavor that's delicious with butter and salt. Easter Egg radishes provide a colorful mix of white, purple, red, and pink varieties that mature in 25 to 30 days.
The mixed colors make harvesting fun for children and add visual interest to salads. White Icicle radishes mature in about 30 days with their distinctive long, white roots that have a milder flavor than red varieties.
2. Arugula (Eruca vesicaria)
Arugula delivers spicy, peppery leaves for baby greens in as little as 21 days. This Mediterranean green, also known as rocket, grows quickly and can be harvested multiple times by cutting leaves about an inch above the soil.
The plants will regrow for several harvests before needing replacement. Sow arugula seeds 1/4 inch deep in rows 6 inches apart, then thin seedlings 3 inches apart.
Arugula thrives in cool weather and partial shade, especially in warmer climates. Its shallow roots benefit from consistent moisture and a light layer of mulch, which keeps the soil cool and retains moisture.
Growing Arugula for Extended Harvests
For a continuous supply of arugula, sow small batches every two weeks throughout spring and again in late summer for fall harvests. The plant bolts (produces flowers and seeds) quickly in hot weather, which makes the leaves more bitter.
Provide afternoon shade in warmer regions to extend the harvest season. Wild arugula varieties like 'Sylvetta' grow more slowly but offer more intense flavor and better heat tolerance.
When very young, harvest leaves are just 1 to 2 inches tall for a milder flavor. As a bonus, allowing some plants to flower will attract beneficial pollinators and can self-seed for future crops.
3. Leaf Lettuce (Lactuca sativa)
Loose-leaf lettuce varieties can be harvested as baby greens in just 28 days or grown to full size in about 45 days. Unlike head lettuce, which takes longer to mature, leaf lettuce allows for "cut and come again" harvesting, where you snip outer leaves while the plant grows from the center.
Plant lettuce seeds 1/8 inch deep, either broadcast across a bed or in rows 12-18 inches apart. Once seedlings emerge, thin them to 6-8 inches apart. Lettuce grows best in cool weather with temperatures between 45-75°F, making it perfect for spring and fall gardens.
Lettuce Varieties That Mature Quickly
Black Seeded Simpson lettuce matures in about 40 days. Its bright green, crinkled leaves form loose, open heads. This heat-tolerant variety is forgiving for beginners and can be harvested earlier as baby greens.
Red Sails lettuce offers beautiful burgundy-tinged leaves in just 45 days, adding color to your garden and plate. Mesclun mix isn't a single variety but a blend of quick-growing lettuces and greens that can be harvested as early as 21 days for baby salads.
These mixes typically include lettuce, arugula, endive, and other leafy greens. Oakleaf varieties like 'Salad Bowl' mature in about 40 days and resist bolting longer than many other types.
4. Spinach (Spinacia oleracea)
Spinach can be harvested as baby leaves in 25 to 30 days or grown to full size in about 40 to 45 days. This nutrient-packed green grows best in cool weather and rich soil with plenty of organic matter.
The leaves have a sweet, mild flavor when young, becoming more robust as they mature. Sow spinach seeds 1/2 inch deep in rows 12 to 18 inches apart, then thin seedlings 3 to 5 inches apart.
Spinach appreciates consistent moisture and benefits from light shade in warmer climates. For best results, plant in early spring as soon as the soil can be worked, or in late summer for fall harvests.
Growing Spinach in Challenging Conditions
Spinach bolts quickly in hot weather and long daylight hours, turning bitter and developing a rigid stem. Plant heat-tolerant varieties like 'Space' or 'Tyee' for extended spring harvests.
Try growing spinach in partial shade in hot climates or use shade cloth to lower soil temperatures. For fall plantings, sow seeds about 6 to 8 weeks before the first expected frost.
Spinach can survive light frosts, which improve flavor by triggering the plant to convert starches to sugars. Some varieties can even overwinter in milder climates when provided with row cover protection.
5. Green Onions (Allium cepa)
Green onions, also called scallions, can be harvested just 30 days after planting when started from sets (small bulbs). They take about 45 days to reach a usable size when grown from seed.
These versatile onions add fresh flavor to countless dishes and require minimal garden space. Plant green onion sets about 1 inch deep and 2 to 3 inches apart in rows spaced 12 inches apart.
For seed starting, sow 1/4 inch deep and thin seedlings to the same spacing. Green onions prefer full sun and consistent moisture, but aren't fussy about soil as long as it drains well.
Creative Ways to Grow Green Onions
Green onions can be regrown from kitchen scraps by placing the white root ends in water or soil. If the water method is used, change the water every few days, and new green growth will appear within days.
This makes them free to grow once you've purchased your first bunch. To maximize garden space, try interplanting green onions between slower-growing vegetables.
Their slim profile means they don't take up much room, and their pungent smell may help deter some pests. Green onions make excellent companions for lettuce, radishes, and other quick-growing crops in containers.
6. Baby Carrots (Daucus carota)
Baby carrots can be harvested in just 30 to 40 days when grown for their tender, sweet immature roots. These aren't the "baby carrots" sold in stores (whittled-down full-size carrots), but genuine young carrots harvested at a smaller size for peak tenderness and flavor.
Sow carrot seeds 1/4 inch deep in rows 12 inches apart. Because carrot seeds are tiny, mix them with sand for more even distribution. Keep the soil consistently moist until germination, which can take 10 to 14 days. Once seedlings emerge, thin them to 1 to 2 inches apart for baby carrots.
Best Varieties for Baby Carrot Harvests
Paris Market carrots mature quickly at about 2 inches in diameter with a round shape, making them perfect for shallow soils or containers. Their sweet flavor and tender texture make them ideal for baby carrot harvests.
Little Finger carrots grow to about 3 to 4 inches long in just 40 days. They have a sweet flavor and a slender shape that doesn't require peeling. Romeo carrots are a round, golf ball-sized variety that matures in about 40 days.
Their shape makes them ideal for containers or shallow soil. Thumbelina carrots are another round variety that reaches harvest size in about 35 days and performs exceptionally well in heavy or rocky soil where longer varieties might struggle.
7. Baby Beets (Beta vulgaris)
Baby beets can be harvested in 40 to 45 days when grown for their tender roots and nutritious greens. At this young stage, beets are lovely and lack the earthiness that some people find challenging in fully mature beets.
The greens are also milder and more tender when harvested young. Sow beet seeds 1/2 inch deep in rows 12 to 18 inches apart. Each "seed" is a cluster containing several embryos, so thin seedlings are 2 to 3 inches apart once they emerge.
Beets prefer cool weather but will tolerate some heat if they receive consistent moisture and have well-drained soil.
Maximizing Your Beet Harvest
For a continuous harvest, sow beet seeds every 2 to 3 weeks throughout spring and again in late summer for fall crops. The thinnings from your beet rows don't need to be wasted; the young greens make excellent additions to salads or can be sautéed like spinach.
Beets grow well in containers at least 8 to 10 inches deep. Choose varieties bred explicitly for baby harvest, like Babybeat or Early Wonder. Keep beets well-watered but not waterlogged for the sweetest flavor, as stress can cause woodiness and bitter flavors even in young roots.
8. Bok Choy (Brassica rapa subsp. chinensis)
Baby bok choy reaches harvest size in 30 to 40 days, making it one of the quickest Asian greens to mature. This versatile vegetable features tender stems and leaves with a mild flavor that works well in stir-fries, soups, and salads.
The entire plant is harvested at once by cutting at the base. Sow bok choy seeds 1/4 inch deep in rows 18 inches apart, thinning seedlings to 6 inches apart for baby-sized heads.
Bok choy prefers cool weather and rich, well-drained soil with consistent moisture. It grows well in spring and fall gardens and can tolerate light frosts.
Bok Choy Growing Tips
Bok choy bolts quickly in hot weather or when stressed, so provide consistent moisture. Consider providing afternoon shade in warmer regions. For the tenderest harvest, pick bok choy when heads are compact and leaves are bright green before any flowering stems appear.
Mini varieties like 'Baby Bok Choy' or 'Shanghai Green' are bred explicitly for early harvest at 4 to 6 inches tall. These compact varieties work particularly well in containers or small garden spaces. For continuous harvests, sow small batches every two weeks during cool seasons.
9. Mustard Greens (Brassica juncea)
Mustard greens can be harvested as baby leaves in just 21 days or grown to full size in about 45 days. When young, these spicy, flavorful greens add a peppery kick to salads, and when mature, they can be cooked to mellow their bite.
The serrated or frilly leaves come in shades of green, red, and purple. Sow mustard seeds 1/4 inch deep in rows 12 to 18 inches apart, thinning seedlings to 6 inches apart for full-sized plants.
For baby greens, seeds can be broadcast more densely. Mustard greens prefer cool weather and rich, moist soil, but are generally adaptable and easy to grow.
Using Mustard Greens in Your Kitchen
Harvest mustard greens by cutting individual outer leaves as needed or harvesting the entire plant at once. Young leaves add a peppery bite to salad mixes, while larger leaves can be sautéed, steamed, or added to soups. The flavor mellows significantly with cooking.
Try growing different varieties for visual interest and flavor variation. Red Giant offers beautiful burgundy leaves, while Southern Giant Curled features intensely ruffled foliage. Japanese varieties like Mizuna have finely cut leaves with a milder flavor, perfect for salads.
10. Turnips (Brassica rapa subsp. rapa)
Baby turnips can be harvested in 30 to 40 days for their sweet, tender roots and nutritious greens. These early-harvested turnips lack the intense flavor that can develop in mature specimens, making them appealing even to those who usually avoid turnips.
The greens cook similarly to spinach and are packed with nutrients. Sow turnip seeds 1/2 inch deep in rows 12 to 18 inches apart, thinning seedlings to 3 to 4 inches apart for baby turnips.
Turnips prefer cool weather and consistent moisture in well-drained soil. They grow well in both spring and fall gardens and actually develop a sweeter flavor after light frosts.
Turnip Varieties for Fast Harvests
Tokyo Cross turnips mature in just 35 days, with snow-white roots that stay tender and sweet even as they size up. This hybrid variety won an All-America Selection award for its reliability and flavor.
Hakurei turnips, ready in about 38 days, are Japanese salad turnips with a lovely flavor that can be eaten raw like an apple. Purple Top White Globe turnips can be harvested young at about 40 days for tender roots, though they're often grown to full size.
Seven Top turnips are grown primarily for their abundant, tasty greens rather than roots and can be harvested in just 30 days from seeding.
