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. This dimension is practical for figuring fertilizer rates and spacings of transplants. Vegetables can easily be tended from either side of the bed. If more growing space is required, several beds of identical dimension are easier to manage than a longer single bed. In fact, several separate beds in the garden will make crop rotation and pest control easier.
