Fewer Weeds . High-plant population in the bed keeps weeds crowded out. Pathways can be covered in landscape fabric or mulch to choke out weeds. The need to frequently rototill the garden can be eliminated. Soil in raised beds can be worked earlier in the season and warms up earlier than traditional gardens.
Rainy weather is less of a hindrance to getting into the garden.
Better Pest Control . Raised bed gardens are easy to cover with insect screening fabric. Crops are easy to rotate from bed to bed preventing a buildup of pests. Plants are healthier and more resistant to insect and disease attack. Bed Dimensions A rectangular bed of soil 3 feet across and 25 feet long provides 75 square feet of space to grow vegetables.
