Best (& Worst) Plants for Raised Bed Gardening

Raised beds work wonderfully for many garden plants, but they’re less idea for others.

Raised bed gardening offers numerous benefits, including improved drainage, better soil quality, and easier maintenance. However, not all crops are equally suited for these contained spaces. Some plants thrive in the unique conditions of raised beds, while others struggle due to their specific needs or growth habits. To help you make the most of your raised bed setup, we’ve compiled a guide to the best and worst plants for raised bed gardens.

Raised beds provide a cozy, contained space that many plants love, but they also present unique challenges. The well-draining soil and controlled environment can be a boon for certain crops, while others may find these conditions limiting. Understanding which plants flourish in raised beds and which ones are better suited for traditional garden plots is key to a successful and productive garden.

Best Plants for Raised Beds

Raised beds are ideal for a variety of crops that appreciate the well-draining, nutrient-rich soil and controlled environment. Here are some of the best plants to grow in raised beds:

Bush Beans are compact and fast-growing, enriching the soil with nitrogen. They mature in about 50 to 60 days and can be planted multiple times in a season.

Carrots and other root vegetables such as radishes and beets thrive in raised beds due to the loose, rock-free soil. Varieties like ‘Nantes’ and ‘Danvers 126’ are recommended for carrots.

Cucumbers prefer the warm soil of raised beds and can be grown with or without trellises. Bush varieties are ideal for compact spaces.

Garlic does likes light, fertile soil and doesn’t compete well with weeds, making it ideal for raised beds. Even in zone 4 Vermont, we have no issues overwintering garlic in raised beds and harvesting huge crops the following year.

Herbs such as basil, chives, and lavender thrive in raised beds due to their preference for nutrient-rich but well-draining conditions.

Leafy Greens like lettuce, spinach, and kale are ideal for raised beds. They grow quickly and can be harvested in as little as 20 to 30 days, making them perfect for succession planting.

Onions benefit from loose soil that prevents rot and promotes healthy bulb formation. They prefer well-draining conditions to prevent moisture accumulation.

Peppers, both bell and hot varieties, thrive in the warm conditions of raised beds. They benefit from well-draining soil that prevents root rot.

Pole Beans, when trellised, provide a vertical element to the garden that saves space while maximizing productivity.

Strawberries spread quickly and can be kept safe from pests in raised beds. They make a great ground cover and can be harvested early in the season. We grow multiple types of strawberries, including pineberries and alpine strawberries, along with normal heirlooms in our raised beds.

Tomatoes, especially determinate varieties, love the warm soil of raised beds. They are compact and bushy, making them well-suited to confined spaces.

Worst Plants for Raised Beds

While many crops flourish in raised beds, some plants struggle due to their growth habits or specific needs. Here are several crops you may want to avoid or reconsider before planting:

Artichokes (Globe Artichokes) require consistently moist soil conditions that raised beds often fail to maintain due to quicker drying out.

Asparagus, another perennial crop with deep roots requiring consistent moisture over time, usually prefers deeper amended soil than standard raised beds offer.

Fruit Trees, with their deep roots and large canopies, quickly outgrow even deep raised beds. Their extensive root systems make them better suited for traditional garden plots or orchards.

Jerusalem Artichokes (Sunchokes) spread aggressively underground and can quickly overcrowd limited raised bed space. Once planted, they’re difficult to eradicate if you decide you want to use the bed for something else.

Large Indeterminate Tomato Varieties can overwhelm raised bed structures due to their size and support requirements. Smaller determinate varieties are better suited for confined spaces.

Large Pumpkins and Winter Squash spread extensively with sprawling vines that quickly overtake raised bed space. These crops need substantial ground area to produce fruit without crowding out other plants.

Perennial Berry Bushes (Raspberries/Blackberries) grow vigorously with sprawling habits that quickly outgrow confined spaces like raised beds.

Rhubarb has a robust root system requiring significant depth and nutrient-rich soil over time, making it better suited for traditional garden plots than shallow raised beds.

Sweet Corn requires a lot of space to ensure proper pollination and healthy ears. Raised beds typically don’t offer enough room for effective pollination.

Watermelon, like pumpkins and squash, demands extensive horizontal space for its vines. Without sufficient room to grow freely, watermelon vines may become overcrowded and fail to produce sizable fruit.

Picking the right plants for your raised beds can really make your garden shine while avoiding those that struggle will save time and effort. By understanding which crops thrive in these unique conditions—and which ones don’t—you’ll set yourself up for a happier, healthier garden filled with productive plants!
