12 Veggies That Give Back: Plant Once, Harvest Forever!

Plant once, harvest forever: certain perennial vegetables offer a sustainable and cost-effective way to enjoy fresh produce year after year. Unlike annuals that require replanting each season, these resilient plants regrow from their roots, providing a continuous yield with minimal effort.

Many gardeners are increasingly drawn to the concept of “plant it and forget it” gardening, focusing on perennial vegetables that offer long-term harvests. These self-sufficient plants not only reduce the amount of time and resources spent on replanting but also contribute to a more sustainable and environmentally friendly garden. They create less soil disturbance, can improve soil health over time, and provide habitat for beneficial insects. These advantages make perennial vegetables a rewarding addition to any garden, whether you’re an experienced gardener or just starting out.

Here are twelve vegetables that can be planted once and harvested for years to come:

1. Asparagus: This springtime delicacy is a true perennial, capable of producing spears for 15 to 20 years or more. Asparagus requires a well-drained location with plenty of sunlight. When planting asparagus crowns, it’s essential to dig a trench about 6-12 inches deep and space the crowns about 12-18 inches apart. The first harvest typically occurs two to three years after planting, allowing the plants to establish a strong root system. Established asparagus beds need minimal maintenance, primarily consisting of weeding and fertilization in the spring. “Asparagus is a great option because it comes back year after year, offering a delicious and healthy harvest with minimal effort,” explains gardening expert Melinda Myers.

Detailed Asparagus Growing Guide:

• Site Selection: Asparagus thrives in full sun, needing at least 6-8 hours of direct sunlight each day. The soil must be well-draining; asparagus does not tolerate soggy conditions. A slightly acidic to neutral soil pH (6.0-7.0) is ideal. Before planting, conduct a soil test to determine pH and nutrient levels. Amend the soil with compost or well-rotted manure to improve drainage and fertility.
• Planting: Asparagus is typically planted using crowns, which are one-year-old dormant plants. Planting is best done in early spring or late fall. Dig trenches that are 6-12 inches deep and about 12-18 inches wide. Space the crowns 12-18 inches apart within the trench. Place the crowns with the buds facing upwards and cover them with 2-3 inches of soil. As the spears grow, gradually fill in the trench until it is level with the surrounding soil.
• Watering: Water newly planted crowns regularly to keep the soil moist but not waterlogged. Once established, asparagus is relatively drought-tolerant but will benefit from occasional deep watering during dry periods.
• Fertilizing: Asparagus is a heavy feeder and benefits from regular fertilization. Apply a balanced fertilizer (e.g., 10-10-10) in early spring before the spears emerge. Side-dress with compost or well-rotted manure throughout the growing season to provide additional nutrients.
• Weeding: Keep the asparagus bed free of weeds, as they can compete with the plants for nutrients and water. Mulch around the plants with organic materials like straw or wood chips to suppress weed growth and retain soil moisture.
• Harvesting: Do not harvest asparagus spears during the first two years after planting to allow the plants to establish a strong root system. In the third year, you can begin harvesting spears for a short period (about 2-3 weeks). In subsequent years, the harvest period can be extended to 6-8 weeks. Harvest spears when they are 6-8 inches tall and about as thick as a pencil. Cut or snap off the spears at ground level. Stop harvesting when the spears become thin, indicating that the plant needs to replenish its energy reserves.
• Maintenance: After the harvest season, allow the asparagus ferns to grow and develop. These ferns will photosynthesize and store energy in the roots for the following year’s growth. In late fall or early winter, after the ferns have turned brown and died back, cut them down to ground level.
• Pest and Disease Management: Asparagus is susceptible to a few pests and diseases, including asparagus beetles, aphids, and Fusarium crown and root rot. Monitor the plants regularly for signs of infestation or disease. Handpick asparagus beetles and their larvae. Use insecticidal soap to control aphids. Ensure good drainage to prevent Fusarium root rot. Plant disease-resistant varieties whenever possible.

2. Rhubarb: Known for its tart stalks often used in pies and jams, rhubarb thrives in cool climates. It prefers full sun to partial shade and well-drained soil. Planting rhubarb crowns involves digging a hole large enough to accommodate the root system, spacing plants about 3-4 feet apart. It’s crucial to avoid harvesting rhubarb in the first year to allow the plant to establish itself. Regular watering and fertilization will promote vigorous growth. “Rhubarb is incredibly hardy and can survive for decades with proper care,” notes Myers.

Detailed Rhubarb Growing Guide:

• Site Selection: Rhubarb needs a location with full sun to partial shade, ideally at least 6 hours of sunlight per day. It requires well-drained soil that is rich in organic matter. The soil pH should be slightly acidic to neutral (6.0-6.8). Avoid planting rhubarb in areas where water tends to collect, as this can lead to root rot.
• Planting: Rhubarb is typically planted using crowns, which are sections of the rootstock with buds (eyes). The best time to plant rhubarb is in early spring or late fall when the plant is dormant. Dig a hole that is about 2 feet wide and 2 feet deep. Mix compost or well-rotted manure into the soil removed from the hole. Place the rhubarb crown in the center of the hole, with the buds facing upwards and about 2 inches below the soil surface. Backfill the hole with the amended soil, gently firming it around the crown. Space rhubarb plants about 3-4 feet apart to allow for ample growth.
• Watering: Water newly planted rhubarb crowns thoroughly to settle the soil and encourage root growth. Keep the soil consistently moist but not waterlogged, especially during the first year. Once established, rhubarb is relatively drought-tolerant but benefits from regular watering during dry periods.
• Fertilizing: Rhubarb is a heavy feeder and benefits from regular fertilization. Apply a balanced fertilizer (e.g., 10-10-10) in early spring before the leaves emerge. Side-dress with compost or well-rotted manure throughout the growing season to provide additional nutrients. Avoid over-fertilizing with nitrogen, as this can promote leafy growth at the expense of stalk production.
• Weeding: Keep the rhubarb bed free of weeds, as they can compete with the plants for nutrients and water. Mulch around the plants with organic materials like straw or wood chips to suppress weed growth and retain soil moisture.
• Harvesting: Do not harvest rhubarb stalks during the first year after planting to allow the plant to establish a strong root system. In the second year, you can begin harvesting a few stalks in the spring. In subsequent years, the harvest period can be extended to 4-8 weeks. Harvest stalks when they are 12-18 inches long and at least 1 inch thick. To harvest, grasp the stalk near the base and pull it away from the plant with a gentle twisting motion. Avoid cutting the stalks, as this can leave an open wound that is susceptible to disease. Remove the leaves from the harvested stalks, as they contain oxalic acid and are toxic. Only the stalks are edible. Stop harvesting when the stalks become thin, indicating that the plant needs to replenish its energy reserves.
• Maintenance: Remove any flower stalks that appear, as they divert energy away from stalk production. In late fall or early winter, after the leaves have died back, cut them down to ground level. Apply a layer of compost or well-rotted manure around the base of the plant to provide winter protection and nutrients.
• Pest and Disease Management: Rhubarb is relatively pest- and disease-resistant. However, it can be susceptible to crown rot if the soil is poorly drained. Ensure good drainage and avoid overwatering to prevent this disease. Rhubarb curculio, a type of weevil, can also attack rhubarb. Handpick the weevils and their larvae to control infestations.

3. Artichokes: Though technically a thistle, artichokes are prized for their edible flower buds. These perennials thrive in mild climates with long growing seasons. Plant artichoke starts in well-drained, fertile soil, providing ample space for their large size. Regular watering and fertilization are essential for optimal bud production. Artichokes require protection from frost in colder regions. “Artichokes add a unique ornamental and culinary element to the garden,” says Myers.

Detailed Artichoke Growing Guide:

• Site Selection: Artichokes require a location with full sun, needing at least 6-8 hours of direct sunlight each day. They thrive in mild climates with long growing seasons. The soil must be well-drained and fertile, with a slightly acidic to neutral pH (6.0-7.0). Amend the soil with compost or well-rotted manure before planting to improve drainage and fertility.
• Planting: Artichokes are typically grown from seeds or transplants. Starting from seeds can be challenging, as artichokes require a long growing season. Transplants are a more reliable option, especially in cooler climates. Plant artichoke transplants in the spring after the last frost. Dig a hole that is large enough to accommodate the root ball. Space plants about 4-6 feet apart to allow for ample growth. Water thoroughly after planting to settle the soil and encourage root growth.
• Watering: Artichokes need consistent moisture, especially during bud formation. Water regularly to keep the soil evenly moist but not waterlogged. Avoid overhead watering, as this can promote fungal diseases. Use drip irrigation or a soaker hose to water the plants at the base.
• Fertilizing: Artichokes are heavy feeders and benefit from regular fertilization. Apply a balanced fertilizer (e.g., 10-10-10) in early spring before the buds begin to form. Side-dress with compost or well-rotted manure throughout the growing season to provide additional nutrients.
• Weeding: Keep the artichoke bed free of weeds, as they can compete with the plants for nutrients and water. Mulch around the plants with organic materials like straw or wood chips to suppress weed growth and retain soil moisture.
• Harvesting: Artichokes are typically harvested when the buds are still tight and the bracts (leaves) are closed. The size of the bud is not always an indicator of maturity, so it’s important to check the bracts. Harvest buds when they are about 3-4 inches in diameter and the bracts are tightly closed. Cut the stem about 2-3 inches below the base of the bud.
• Maintenance: After harvesting, cut the stem back to the ground to encourage new growth. In colder climates, artichokes require winter protection. Cut the plant back to the ground in the fall and cover it with a thick layer of mulch, straw, or leaves to insulate the roots.
• Pest and Disease Management: Artichokes can be susceptible to a few pests and diseases, including aphids, artichoke plume moths, and powdery mildew. Monitor the plants regularly for signs of infestation or disease. Use insecticidal soap to control aphids. Remove and destroy any infected plant parts to prevent the spread of powdery mildew.

4. Egyptian Walking Onions: These unique onions propagate themselves by toppling over, with bulbets at the top of their stalks that root and form new plants. They are extremely hardy and require minimal care, thriving in a variety of soil conditions. Plant the bulbets in the fall or spring, spacing them about 6-8 inches apart. Both the bulbs and the green stalks can be used in cooking. “Egyptian walking onions are a novelty item that also provides a reliable source of onions,” says Myers.

Detailed Egyptian Walking Onions Growing Guide:

• Site Selection: Egyptian walking onions are very adaptable and can grow in full sun to partial shade. They are not too picky about soil type but prefer well-drained soil.
• Planting: Plant the bulbets (small bulbs at the top of the stalks) in the fall or spring. Plant them about 1 inch deep and 6-8 inches apart. The top of the bulbet should be just below the soil surface.
• Watering: Water regularly after planting to establish the roots. Once established, they are relatively drought-tolerant.
• Fertilizing: They are not heavy feeders, but a side dressing of compost in the spring can be beneficial.
• Maintenance: The unique characteristic of these onions is that the top-heavy stalks with bulbets will eventually fall over, and the bulbets will root, creating new plants. This is how they “walk.” You can harvest the bulbets for planting or culinary use. The underground bulbs can also be harvested like regular onions.
• Pest and Disease Management: They are relatively pest and disease-free.

5. Garlic: While technically a bulb, garlic is often grown as an annual, but some varieties can persist for several years if left undisturbed. Plant garlic cloves in the fall, spacing them about 6 inches apart. Garlic prefers well-drained soil and full sun. Harvest the bulbs in the summer when the leaves begin to yellow. “Garlic is a kitchen staple that is easy to grow and store,” Myers states.

Detailed Garlic Growing Guide:

• Site Selection: Garlic needs a location with full sun, requiring at least 6 hours of direct sunlight each day. It thrives in well-drained soil that is rich in organic matter. The soil pH should be between 6.0 and 7.0. Avoid planting garlic in areas where water tends to collect, as this can lead to bulb rot.
• Planting: Garlic is typically planted in the fall, about 4-6 weeks before the ground freezes. This allows the cloves to develop roots before winter. Separate the garlic bulb into individual cloves. Select the largest and healthiest cloves for planting. Plant the cloves about 2 inches deep and 6 inches apart, with the pointed end facing up. Space rows of garlic about 12 inches apart.
• Watering: Water the garlic bed thoroughly after planting to settle the soil and encourage root growth. Keep the soil consistently moist but not waterlogged, especially during the fall and spring. Reduce watering as the bulbs begin to mature in the summer.
• Fertilizing: Garlic is a heavy feeder and benefits from regular fertilization. Apply a balanced fertilizer (e.g., 10-10-10) in early spring when the shoots begin to emerge. Side-dress with compost or well-rotted manure throughout the growing season to provide additional nutrients.
• Weeding: Keep the garlic bed free of weeds, as they can compete with the plants for nutrients and water. Mulch around the plants with organic materials like straw or wood chips to suppress weed growth and retain soil moisture.
• Harvesting: Garlic is typically harvested in the summer when the leaves begin to turn yellow and fall over. This usually occurs about 8-9 months after planting. Carefully dig up the garlic bulbs, being careful not to damage them. Cure the garlic bulbs by allowing them to dry in a well-ventilated area for 2-3 weeks.
• Maintenance: Remove any flower stalks (scapes) that appear, as they divert energy away from bulb development. In colder climates, garlic benefits from winter protection. Mulch around the plants with a thick layer of straw or leaves to insulate the soil and prevent freezing.
• Pest and Disease Management: Garlic is relatively pest- and disease-resistant. However, it can be susceptible to white rot, a fungal disease that affects the roots and bulbs. Ensure good drainage and avoid overwatering to prevent this disease. Garlic can also be affected by onion maggots, which can damage the bulbs. Use row covers to protect the plants from these pests.

6. Horseradish: Known for its pungent root, horseradish is a hardy perennial that can become invasive if not contained. Plant horseradish roots in well-drained soil, ideally in a location where it can be easily managed. Harvest the roots in the fall or early spring. “Horseradish adds a zesty kick to sauces and condiments,” Myers notes.
