The first step to any successful vegetable garden is preparing the soil. Just because you have filled your raised bed with topsoil from your local nursery it does not mean the soil is nutrient rich and amended to a texture perfect for vegetables. Add compost to the soil to create a loam texture, which helps ensure the plants will grow healthy and strong, and grant you a full harvest.
Add a 2-inch layer of nursery compost to the top of the soil. Mix it in with a shovel all the way down to the bottom of the raised bed. Make sure the soil is about 2 inches below the top of the raised bed, removing some of the mixture if necessary. Rake the bed even.
Draw a line down the center of the raised bed, lengthwise, at the planting depth required for the particular vegetable seed you are planting. This information is found on the back of the seed packet. If your raised bed is wide enough to plant two rows of vegetables, then make two lines a foot from each side of the bed. Use your finger or a pencil to make this line
Drop the seeds down the indented line at the spacing required by the particular vegetable seed. Again, this information is found on the back side of the seed packet.
Push soil over the top of the seeded line, all the way down to the end.
Attach the spray nozzle to the hose. Gently spray the raised bed soil. The soil must be kept moist for the seeds to germinate. However, never water so much that the soil turns to mud. Check the soil often and spray again when it begins to dry.
