Here is the blueprint by Jonathan Leger which explains what you need to do to create a new kitchen garden.

How To Successfully Plan A Kitchen Garden
In contrast to ornamental gardens, kitchen gardens yield edible and possibly, medicinal crops. By opting to plant one, you can decrease your grocery bills in the long run and increase your self-reliance. Involve other members of the household according to their individual abilities. Communing with nature and enjoying freshly harvested foods is a pleasurable and rewarding activity.
You will need to determine the size and location of the plot. Look around your yard for a sunny area that is close to the kitchen door and a water source. While you may need to make accommodations regarding easy access to water or the kitchen, it is vital that your kitchen garden has direct sunlight at least eight hours per day.
Once you have chosen the location, you need to decide how you want to plant the crops. Are you considering using multiple containers, raised beds, frames for hanging gardens or other innovative planting methods? Perhaps a combination of these techniques best fulfills your ideal garden.

If you plan to use the soil already there, you will need to test it to find out how much sand and clay are in it. Additionally, you should check the pH levels in several locations. Rectify any troubles, preferably through organic methods. After all, you are investing your time and will ultimately ingest the crops you are tending. Doesn’t it make sense to avoid chemicals as much as possible?
Next comes deciding what crops you want to plant. Find out what zone you live in so you can quickly determine if a plant does well in your area and the specifics regarding planting season there. Your prior gardening experience also comes into play.
If you have minimal time logged in pulling weeds, watering, implementing pest control and fertilizer methods and other gardening activities, you may want to begin your first garden with plants that are known to be easy to grow in your community. You will gain practice, confidence and fresh fruits, vegetables and herbs.
Another consideration is how much you and other members of the household enjoy a particular food and your interests and abilities regarding long-term storage of your harvests. If your yield is greater than what you and your family can consume while still fresh, you will need to have plans for the excess.
In fact, you may even plan for that with your design and can then freeze, dehydrate or can the extra for use during the winter. Some regions of the country have mild enough winters that the garden can produce various edibles throughout the year.

Once you have an idea of the crops you want to grow, begin experimenting with how to lay them out. You can do this with software designed for garden planning or pull out some graph paper and a pencil. Take into account the path of the sun throughout the day and the height of the various plants.
Once you are satisfied with the layout of your kitchen garden, you can start your seeds or buy seedlings. Many gardening novices prefer to use seedlings to increase success and yield. Monitor the soil health, water levels, pH, and mulching to ensure your plants thrive while growing. Employ organic methods of pest control and fertilizer for a healthier garden.
You can continue to expand your garden each year, enjoying the additions to your annual harvest. Kitchen gardens are a practical addition to virtually every household. Start planning yours today and you will be on the path toward growing fantastic, natural fruits, herbs and vegetables for your culinary pleasures.
