12 Fast-Growing Vegetables You Can Harvest in Just 30 Days

If you are eager to grow fresh, homegrown vegetables but do not want to wait months for a harvest, you are in luck! Some vegetables grow incredibly fast, allowing you to enjoy fresh produce in as little as 30 days. Whether you are a beginner gardener or looking for quick-growing crops to fill gaps in your garden, these vegetables will provide delicious and nutritious rewards in no time. Here are 12 fast-growing vegetables you can harvest within a month.

1. Radishes

Radishes are one of the fastest-growing vegetables, often ready for harvest in just 20 to 30 days. These crisp, peppery root vegetables thrive in cool weather and can be planted in both spring and fall. They require minimal care—just well-draining soil and regular watering to prevent them from turning bitter. You can also eat radish greens, making this a two-for-one crop that grows quickly and adds a fresh bite to salads.

2. Arugula

If you love peppery, nutrient-rich greens, arugula is an excellent choice for a speedy harvest. This leafy green germinates within a few days and is ready to pick in about three weeks. It thrives in cooler temperatures and does best in partial shade. Because it grows so fast, you can plant multiple batches throughout the season for a continuous supply. Arugula is perfect for salads, sandwiches, and homemade pesto.

3. Green Onions

Green onions, also called scallions, are among the easiest vegetables to grow and can be harvested in about 21 to 30 days. Unlike traditional onions, they do not require bulb development, which speeds up their growth. They can be grown in garden beds or even in small containers on a sunny windowsill. Simply snip the green tops for fresh garnish, and the plant will continue to grow, providing you with an ongoing harvest.

4. Spinach

Spinach is a nutrient-dense leafy green that matures quickly, with baby leaves ready for harvest in as little as 20 days. It thrives in cool temperatures and can be grown in both spring and fall. Regularly picking the outer leaves encourages continuous growth, giving you a steady supply of fresh greens. Packed with iron and vitamins, spinach is a fantastic addition to salads, smoothies, and stir-fries.

5. Lettuce

Leaf lettuce varieties, such as Romaine, Butterhead, and Loose-leaf, can be harvested in about 30 days, especially if you pick the outer leaves rather than waiting for a full head to develop. This cut-and-come-again method allows the plant to keep producing for weeks. Lettuce grows well in both garden beds and containers, making it perfect for small spaces. It is a staple for fresh salads, wraps, and sandwiches.

6. Mustard Greens

Mustard greens are an excellent choice for quick-growing leafy greens, ready to harvest in just 20 to 30 days. They have a slightly spicy, peppery flavor, adding a kick to salads and stir-fries. Mustard greens thrive in cooler temperatures and are highly resistant to pests. Regularly picking the young leaves encourages new growth, ensuring you have a continuous supply of fresh, nutrient-packed greens throughout the season.

7. Turnip Greens

While turnips themselves take longer to mature, their greens can be harvested in just three weeks. These leafy greens are packed with vitamins A, C, and K, and they can be used in salads, sautés, and soups. If you allow the plant to keep growing, you can enjoy the turnip roots later in the season. This makes turnips a dual-purpose crop that is perfect for quick harvesting and long-term yield.

8. Bok Choy

Bok choy, or baby bok choy, is a fast-growing leafy vegetable that can be harvested within 30 days. This Asian green is great for stir-fries, soups, and salads. It grows well in cool weather and partial shade, making it a versatile crop for different garden conditions. Picking outer leaves as needed allows the plant to keep producing, giving you a steady supply of fresh, crunchy greens.

9. Cress

Garden cress is one of the quickest-growing vegetables, often ready to harvest within just two weeks. This tiny, nutrient-packed green has a peppery taste and is perfect for garnishing salads, sandwiches, and soups. Cress thrives in both garden beds and containers and even grows well indoors on a windowsill. Because of its fast growth, you can plant multiple batches for a continuous supply throughout the season.

10. Kale Microgreens

Kale microgreens are baby versions of kale plants that can be harvested in as little as 10 to 14 days. They are loaded with vitamins and antioxidants, offering a nutritional powerhouse in a tiny package. Unlike full-grown kale, microgreens require very little space and can be grown indoors in trays or small containers. They are excellent for adding a fresh crunch to salads, sandwiches, and smoothies.

11. Swiss Chard

Swiss chard is a quick-growing leafy green that can be harvested as baby greens in about 25 to 30 days. The young leaves are tender and flavorful, perfect for salads and sautés. If you let the plant grow longer, it will produce large, colorful leaves that can be used like spinach. Swiss chard is easy to grow and thrives in both garden beds and containers, making it a great choice for small-space gardening.

12. Baby Carrots

While full-sized carrots take longer to mature, baby carrots can be harvested in just 30 days. These sweet, tender roots are perfect for snacking, roasting, or adding to salads. They grow best in loose, well-draining soil and need consistent moisture for even growth. If you are short on time and space, you can also grow baby carrots in deep containers on a patio or balcony.
