Advantages of Raised Bed Gardening
I would have to say the most important advantage is greatly reduced soil compacting. Plant roots need air. In an ordinary garden, you can’t avoid stepping in the garden bed occasionally when doing your everyday gardening. A properly designed raised bed garden allows you to do all you’re gardening from the garden path.
Plants can be spaced a little closer together in a raised bed because you don’t need places to step. This increases productivity per square foot of bed and reduces weeding when the plants begin to mature.
Note: Avoid the temptation to crowd your plants. You will still want to use generous plant spacing because your plants will grow much larger in raised beds.
Raised beds tend to drain away excess moisture better than ordinary garden beds. This is another advantage that helps the plant roots to breath. In areas that have saturated soil like Florida and many areas of the South, raised beds may be the only way you can grow many types of plants.
Soil conditions and types can be controlled more efficiently in a raised bed and they can be varied easily from bed to bed. Raised beds are the answer when topsoil is thin.
Water, fertilizer, compost, mulch, etc. can be applied more carefully because they only need to be applied to the garden beds.
Various studies have shown that raised garden beds produce 1.4 to 2 times as much vegetables and flowers per square foot as ordinary beds, due mainly to the above advantages. You can have a smaller and more manageable garden that produces more vegetables for your table.
