Raised garden beds make growing vegetables, herbs and flowers easy and convenient. But after a season or two of planting, the soil in raised beds can become compacted and depleted of nutrients Refreshing your raised bed soil is essential to ensure ongoing garden success.
Follow these tips to reinvigorate your raised garden bed soil
1. Remove Dead Plant Material
Start by clearing out any spent plants, dropped leaves, stems and other debris. These can harbor pests and diseases. Remove anything that appears diseased and discard it (don’t compost).
2. Test the Soil
Get a soil test kit to analyze your raised bed’s pH and nutrient levels. This will reveal any deficiencies you need to correct Contact your local agricultural extension office for testing assistance
3. Work in Compost or Manure
Add one to two inches of compost, well-rotted manure, leaf mold, or some other type of organic material to the top of the soil. Then, use a spade or garden fork to mix the nutrients back into the top 4 to 6 inches of soil.
4. Add a Layer of Mulch
Top off amended beds with 1-2 inches of shredded leaves, straw, raw manure or other organic mulch. This will conserve moisture and further feed the soil as it breaks down.
5. Consider Cover Crops
Sow a cover crop like clover or rye in fall and turn under in spring before planting. As they decompose, cover crops infuse beds with organic matter.
6. Address Low Spots
Over time, raised bed soil settles. Fill any sunken spots with a mix of quality topsoil and compost. Level beds for even root development.
7. Fertilize Strategically
Use organic granular fertilizers at planting time to give beds a nutrient boost. Follow package rates carefully to avoid over-fertilizing.
Rotate Crops
When replanting raised beds, rotate annual vegetable families to different areas than the previous season. This prevents disease and nutrient deficiencies.
Don’t Overwork Soil
Avoid excessive digging that damages soil structure. Gently turn amendments into just the top few inches using a pitchfork or spade.
Why Refreshing Beds is Needed
Raised beds loose nutrients with each harvest. Eventually plants need an extra feed. Compacted or shrinking beds also deprive roots of the light, fluffy soil they love. Replenishing beds annually provides many benefits:
- Restores nutrients removed by plants
- Rebuilds depleted organic matter
- Reduces compaction and improves drainage
- Allows for crop rotation to prevent disease
- Encourages vigorous root development
- Discourages weeds due to rich soil
- Increases beneficial microbial activity
Basically, recharged soil equals healthier, more productive plants!
When to Refresh Raised Garden Beds
Anytime the beds are not occupied is a good time for a soil refresh:
- Fall – Prep beds after harvest and sow cover crops
- Late Winter – Turn in cover crops and amend soil
- Early Spring – Fertilize soil and allow time to absorb before planting
- Mid Summer – Amend open beds between spring and fall crops
Adjust timing based on your climate and planting schedule.
