What to Plant in Raised Beds: 20 Best Vegetables & Herbs

Why Raised Beds Are Perfect for Growing Almost Anything

One of the most exciting moments in gardening is deciding what to plant in your new raised bed. The good news? Raised beds are incredibly versatile. With better drainage, warmer soil, and improved soil quality, you can grow vegetables, herbs, and flowers that might struggle in traditional ground-level gardens.

Whether you're a complete beginner or an experienced gardener upgrading to raised beds, this guide will help you choose the 20 best plants that thrive in elevated gardens. We'll cover everything from classic favorites like tomatoes to unexpected winners like sunflowers, plus practical tips on spacing, timing, and companion planting.

Top 10 Vegetables for Raised Beds

1. Tomatoes (Solanum lycopersicum)

Why they love raised beds: Tomatoes thrive in the warm, well-drained soil that raised beds provide. The improved drainage prevents root rot, while the ability to control soil quality means you can give them the rich, nutrient-dense environment they crave.

Spacing: Plant 45-60 cm apart for determinate varieties, 60-90 cm for indeterminate (vining) types. Add sturdy stakes or cages at planting time.

When to plant: After last frost (mid-May in Central Europe, zones 6-7). Start indoors 6-8 weeks earlier for a head start.

Pro tip: GridGarden's 60cm depth beds are ideal for deep-rooted tomatoes. Use our configurator to plan a dedicated tomato bed with proper spacing.

2. Peppers (Capsicum annuum)

Why they love raised beds: Peppers are heat lovers, and raised beds warm up faster in spring. The excellent drainage prevents waterlogged roots, which peppers absolutely hate.

Spacing: 30-45 cm apart. They're compact, making them perfect for smaller beds.

When to plant: Same as tomatoes—wait until soil warms to at least 15°C (late May in cooler climates).

3. Lettuce (Lactuca sativa)

Why it loves raised beds: Lettuce has shallow roots, making it perfect for raised beds. The controlled environment means you can succession plant every 2 weeks for continuous harvests.

Spacing: 15-30 cm apart depending on variety (leaf lettuce can be closer, head lettuce needs more room).

When to plant: Early spring (March-April) and again in late summer (August) for fall harvest. Lettuce bolts in heat, so avoid midsummer planting.

4. Radishes (Raphanus sativus)

Why they love raised beds: The loose, rock-free soil of raised beds allows radishes to develop perfectly round roots. They're also one of the fastest vegetables—harvest in just 3-4 weeks.

Spacing: 5-8 cm apart. Perfect for succession planting or filling gaps between slower-growing crops.

When to plant: Early spring through early summer, then again in fall. Avoid the hottest months.

5. Carrots (Daucus carota)

Why they love raised beds: Carrots need deep, loose soil free of rocks and clumps. Raised beds filled with quality soil produce straight, beautiful carrots instead of forked, stunted roots.

Spacing: Thin to 5-8 cm apart after germination. Crowded carrots won't develop properly.

When to plant: Early spring (March-April) for summer harvest, or mid-summer for fall/winter storage carrots.

Pro tip: Choose a GridGarden bed at least 30 cm deep for standard carrots, or 40-60 cm for long varieties.

6. Zucchini/Courgette (Cucurbita pepo)

Why it loves raised beds: Zucchini is a heavy feeder that benefits from the nutrient-rich soil you can provide in raised beds. The improved drainage also helps prevent powdery mildew.

Spacing: 90-120 cm apart—these plants get BIG. One or two plants will feed a family all summer.

When to plant: After last frost (mid-May). Direct seed or transplant started indoors.

7. Bush Beans (Phaseolus vulgaris)

Why they love raised beds: Bush beans don't require support and thrive in the warm soil of raised beds. They're also nitrogen-fixers, improving your soil for the next crop.

Spacing: 10-15 cm apart in rows 45 cm apart. Compact enough for smaller beds.

When to plant: After soil warms (mid-May onwards). Make succession plantings every 2-3 weeks until mid-July for continuous harvest.

8. Peas (Pisum sativum)

Why they love raised beds: Peas are cool-season crops that benefit from the early soil warming in raised beds. They're also nitrogen-fixers like beans.

Spacing: 5-8 cm apart along a trellis or support. Even "bush" peas benefit from some support.

When to plant: Very early spring (March-early April) as soon as soil can be worked. Plant again in late summer for fall crop.

9. Spinach (Spinacia oleracea)

Why it loves raised beds: Spinach appreciates the excellent drainage and nutrient-rich soil. It's also shallow-rooted, making it perfect for interplanting with taller crops.

Spacing: 8-10 cm apart for baby leaves, 15 cm for full-sized plants.

When to plant: Early spring (March-April) and late summer (August-September). Bolts quickly in heat.

10. Kale (Brassica oleracea var. sabellica)

Why it loves raised beds: Kale is a heavy feeder that benefits from rich soil. It's also cold-hardy, often improving in flavor after frost—perfect for extending your raised bed season.

Spacing: 30-45 cm apart. Kale gets bushy, so give it room.

When to plant: Spring (April-May) or mid-summer (July) for fall/winter harvest. Fall-planted kale is sweeter.

Top 5 Herbs for Raised Beds

1. Basil (Ocimum basilicum)

Why it loves raised beds: Basil is a heat-loving annual that thrives in the warm, well-drained conditions of raised beds. Perfect companion for tomatoes and peppers.

Spacing: 20-30 cm apart. Pinch regularly to encourage bushiness and prevent flowering.

When to plant: After last frost (mid-May). Extremely frost-sensitive.

2. Parsley (Petroselinum crispum)

Why it loves raised beds: Parsley has a long taproot that appreciates deep, loose soil. It's a biennial that can overwinter in milder climates.

Spacing: 15-20 cm apart. Slow to germinate (2-3 weeks), so be patient.

When to plant: Early spring (March-April) or late summer.

3. Dill (Anethum graveolens)

Why it loves raised beds: Dill's taproot needs loose soil, and raised beds provide perfect drainage. It attracts beneficial insects and is a host plant for swallowtail butterflies.

Spacing: 20-30 cm apart. Succession plant every 3-4 weeks for continuous harvest.

When to plant: Spring through early summer (April-June). Goes to seed quickly in heat.

4. Chives (Allium schoenoprasum)

Why they love raised beds: Chives are perennial herbs that come back year after year. Their purple flowers are edible and attract pollinators. They're also mild pest deterrents for other crops.

Spacing: 20 cm apart. Clumps will expand over time—divide every 3-4 years.

When to plant: Spring (March-May) or fall (September). Once established, they're maintenance-free.

5. Mint (Mentha spp.)

Why it loves raised beds: Mint thrives in moist conditions but needs good drainage to prevent root rot. However—IMPORTANT WARNING—mint spreads aggressively through underground runners.

Spacing: 30-45 cm apart, but plant in a buried container to prevent it from taking over your entire bed. Use a large pot with drainage holes, sink it into the bed, and trim off any runners that escape.

When to plant: Spring (April-May). Perennial in zones 5-9.

Pro tip: Consider dedicating a small GridGarden bed exclusively to mint if you use it frequently—just accept it will dominate the space.

Top 5 Flowers for Companion Planting

1. Marigolds (Tagetes spp.)

Why plant them: Marigolds deter aphids, whiteflies, and root nematodes. Their pungent scent confuses pests looking for vegetables. Plus, they're cheerful and bloom all summer.

Spacing: 20-30 cm apart along bed edges or interspersed between vegetables.

When to plant: After last frost (May). Direct seed or transplant.

2. Nasturtiums (Tropaeolum majus)

Why plant them: Nasturtiums are "trap crops" that attract aphids away from vegetables. Both flowers and leaves are edible with a peppery flavor. They're also beautiful trailing over bed edges.

Spacing: 20-30 cm apart. Can be trained to climb or allowed to sprawl.

When to plant: After last frost (May). Self-seeds readily.

3. Lavender (Lavandula angustifolia)

Why plant it: Lavender attracts pollinators and repels moths, fleas, and mosquitoes. It's drought-tolerant once established and provides lovely cut flowers.

Spacing: 45-60 cm apart. Needs excellent drainage—perfect for raised beds.

When to plant: Spring (April-May) or fall (September). Perennial in zones 5-9.

Pro tip: Plant lavender on the sunny side of taller crops, or dedicate a corner of your bed to perennial herbs.

4. Calendula (Calendula officinalis)

Why plant it: Calendula attracts beneficial insects, particularly hoverflies whose larvae eat aphids. The flowers are edible and have medicinal properties. They bloom prolifically and self-seed.

Spacing: 20-30 cm apart.

When to plant: Early spring (March-April) or fall (September). Tolerates light frost.

5. Sunflowers (Helianthus annuus)

Why plant them: Compact sunflower varieties attract pollinators and provide height and structure. They also make excellent cut flowers and provide seeds for birds (and you).

Spacing: 30-45 cm apart for compact varieties. Choose dwarf varieties (60-120 cm tall) for raised beds rather than giants.

When to plant: After last frost (May). Succession plant every 2-3 weeks for continuous blooms.

Planning Your Raised Bed Layout

The beauty of raised beds is that you can plan exactly what goes where. Here are some proven layouts:

4x8 ft (120x240 cm) bed: Plant tomatoes down the center with basil and marigolds on either side. This classic combination maximizes space while providing companion planting benefits.

3x6 ft (90x180 cm) bed: Perfect for a salad garden. Plant lettuce and spinach on the shady side, radishes for quick harvests, and chives for perennial production.

4x4 ft (120x120 cm) bed: Ideal for square-foot gardening. Divide into 1-foot (30 cm) squares and plant different crops in each square based on spacing requirements.

Pro tip: Use GridGarden's 3D configurator to design beds sized specifically for your chosen crops. You can visualize different shapes and depths before ordering, ensuring your plants have exactly the space they need to thrive.

Key Takeaways for Raised Bed Planting Success

• Start with quality soil: Fill beds with a mix of compost, peat moss or coco coir, and vermiculite or perlite (1:1:1 ratio).
• Consider depth: Most vegetables need 20-30 cm depth, root crops like carrots need 30-40 cm, and tomatoes thrive with 40-60 cm.
• Practice crop rotation: Don't plant the same family in the same spot year after year. Rotate between heavy feeders (tomatoes, peppers), legumes (beans, peas), and light feeders (herbs, lettuce).
• Succession plant: For continuous harvests of quick crops like lettuce, radishes, and beans, plant small amounts every 2-3 weeks.
• Mix flowers with vegetables: Companion planting with marigolds, nasturtiums, and calendula improves pollination and pest control naturally.
• Match crops to climate: Cool-season crops (peas, spinach, lettuce) go in early spring and fall. Warm-season crops (tomatoes, peppers, basil) wait until after last frost.
• Don't crowd plants: Proper spacing ensures good air circulation, reducing disease risk and allowing each plant to reach its full potential.

Key Takeaways

• Intensive spacing doubles yield — Plant lettuce 6" apart (vs 12" traditional), bush beans 4" apart (vs 6"), using raised bed soil quality to support density
• Tomatoes are space hogs — Each indeterminate tomato needs 4 sq ft (2×2 grid); determinate varieties need 2-3 sq ft; cherry tomatoes produce 200+ fruits per plant
• Succession planting extends harvest — Plant lettuce, radishes, and beans every 14 days from spring to fall for continuous production instead of one-time glut
• Vertical growing triples space — Pole beans, peas, cucumbers, and indeterminate tomatoes on trellises yield 3x more per square foot than bush varieties
• Cool-season crops bookend summer — Plant lettuce, spinach, peas, radishes in early spring and again in late summer; they bolt in heat but thrive in 50-70°F weather
• Avoid space wasters — Corn, pumpkins, and melons need 6-9 sq ft per plant; grow these in-ground unless you have multiple large beds
• Herbs fill gaps profitably — Basil, parsley, cilantro fit in 6-12" spaces between larger plants and provide continuous harvests worth €3-5 per plant weekly
• Root depth varies widely — Lettuce and radishes thrive in 6" soil; tomatoes and carrots need 12"+; plan bed depth accordingly or grow shallow-rooted crops in shorter beds
