Raised Bed Gardening
Raised bed gardening is a method of growing plants in soil that is elevated above ground level, typically contained within a frame or structure. Raised beds offer superior drainage, warmer soil temperatures, reduced compaction, fewer weeds, and better ergonomics compared to in-ground gardening. They are suitable for vegetables, herbs, flowers, and small fruits, and can be adapted for any space from small patios to large backyards. Raised beds are particularly beneficial for areas with poor native soil, limited mobility gardeners, and urban environments. This topic covers materials selection, soil preparation, sizing, irrigation, pest management, planting strategies, season extension, and long-term soil maintenance for productive raised bed gardens.
