What are raised garden beds and why should I use them?
Raised garden beds are garden plots that are elevated above the surrounding soil, often framed by wood, stone, or other materials. They provide a defined space for growing plants, offering better soil drainage, improved fertility, and extended growing seasons. By elevating the plants, raised beds can also help reduce soil compaction, making it easier for roots to grow and access nutrients.
Additionally, raised garden beds can add aesthetic appeal to your landscape. They make gardening more accessible for people who may have mobility issues since they can be built at different heights. The controlled environment allows for better pest management and can help deter weeds, which can lead to a more productive and healthier garden overall.
How often should I refresh my raised garden bed soil?
It is generally recommended to refresh the soil in your raised garden bed at least once a year, ideally in the spring before planting. This ensures that the soil remains nutrient-rich and maintains its structure, which is essential for healthy plant growth. However, the frequency can depend on what you are planting and how well the plants are performing.
If you notice your plants struggling or showing signs of nutrient deficiencies, it may be an indication that the soil needs to be refreshed more frequently.
