Perennial plants, the stalwarts of the garden, are those remarkable green companions that grace us with their presence year after year. Unlike annuals that complete their life cycle within a single growing season, perennials persist, returning to bless your garden with their beauty and bounty. In this guide, we'll delve into the world of perennial plants, exploring their enduring nature and providing insights into growing and enjoying varieties in your raised garden bed. The following content also has some reference value for raised garden beds.
Understanding Perennials: Garden Allies for the Long Haul
Perennial plants are those that live for more than two years, often regrowing from the same roots season after season. They are the backbone of sustainable gardening, providing reliable yields and enhancing the overall aesthetic of your garden. As these plants establish deeper root systems, they become more resilient, requiring less maintenance than their annual counterparts.
Perennial Plants for Your Raised Garden Bed
- Planting: Choose a sunny location with well-draining soil. Asparagus prefers a slightly acidic to neutral pH.
- Growing: Patience is key, as asparagus takes a couple of years to establish. Once established, it can produce for up to 20 years.
- Caring: Mulch around asparagus plants to retain soil moisture and suppress weeds.
- Harvesting: Harvest spears when they reach 6-8 inches in height, and cease harvesting in late spring to allow the fern-like foliage to grow.
- Planting: Choose a spot with well-draining soil that is sunny to slightly shaded. Rhubarb appreciates slightly acidic to neutral soil.
- Growing: Rhubarb is a hardy perennial, but it benefits from regular watering during dry spells.
- Caring: Remove flower stalks to redirect energy into leaf and stalk production. Mulch around the base to conserve moisture.
- Harvesting: Harvest mature stalks by pulling them away from the plant. Refrain from taking out more than one-third of the plant at once.
- Planting: Choose a sunny location with well-draining soil. Raised beds enhance drainage and make it easier to control runners.
- Growing: Provide ample sunlight and water regularly, especially during fruit development.
- Caring: Mulch around strawberry plants to prevent soil splashing on berries and deter weeds.
- Harvesting: Pick ripe strawberries when they are fully red, typically every 2-3 days during peak season.
- Planting: Consider growing mint in containers within the raised bed to control its invasive nature.
- Growing: Mint thrives in partial shade with consistently moist soil.
- Caring: Prune regularly to keep mint from becoming too leggy. Divide plants every 2-3 years.
- Harvesting: Harvest mint leaves regularly for culinary or medicinal use.
- Planting: Choose a sunny location with well-draining soil. Lavender prefers slightly alkaline soil.
- Growing: Water sparingly once established, as lavender is drought-tolerant.

- Planting: Select a sunny location with well-draining soil. Sage prefers slightly alkaline soil.
- Growing: Water sage sparingly once established, as it is drought-tolerant.
- Caring: Prune regularly to maintain a bushy shape. Replace plants every 3-4 years for optimal production.
- Harvesting: Harvest sage leaves as needed for culinary or medicinal use.
- Planting: Choose a sunny location with well-draining soil. Artichokes benefit from protection against strong winds.
- Growing: In colder climates, provide winter protection by mulching around the base.
- Caring: Prune dead or damaged leaves to promote air circulation. Divide plants every few years.
- Harvesting: Harvest artichokes when the buds are firm but not fully opened.
- Planting: Plant chives in well-draining soil in a sunny to partially shaded location.
- Growing: Water regularly to keep the soil consistently moist.
- Caring: Divide chive clumps every 2-3 years to maintain plant vigor.
- Harvesting: Snip chive leaves with scissors, leaving at least 2 inches of growth for regrowth.
- Planting: Choose a sunny location with well-draining soil. Oregano prefers slightly alkaline conditions.
- Growing: Water oregano moderately, allowing the soil to dry out between watering.
- Caring: Prune oregano regularly to encourage bushy growth. Divide plants every 3-4 years.
- Harvesting: Harvest oregano leaves just before the flowers open for the best flavor.
- Planting: Grow lemon balm in partial shade with well-draining soil.
- Growing: Water consistently to keep the soil evenly moist.
- Caring: Prune lemon balm regularly to control its spread. Divide plants every 2-3 years.
- Harvesting: Harvest lemon balm leaves for teas and culinary uses.
Tips for Planting, Growing, Caring, and Harvesting Perennials
- Choose an appropriate location with the right sunlight and soil conditions for each perennial.
- Follow spacing recommendations to avoid overcrowding and guarantee adequate air circulation.
- Water each perennial according to their specific needs. Some may prefer consistently moist soil, while others thrive in drier conditions.
- For healthy growth, use a balanced, all-purpose fertilizer in the spring.
- Mulch around the base of plants to retain moisture, suppress weeds, and regulate soil temperature.
- Prune as needed to keep shape, enhance bushy growth, and get rid of dead or damaged foliage.
- For ornamental perennials, harvesting may not be necessary. Enjoy the garden's blossoms and remove dead flowers for continued flowering.
- For edible perennials like lavender, rosemary, and others, harvest leaves, flowers, or stems as needed for culinary or medicinal purposes.
