The end of winter and early spring is a great time to plan for your vegetable garden. Whether you have an existing garden or you are planning a new garden space, these tips will help get you started. 
Look closely at the locations of the space. Throughout the course of a day, notice the features such as trees, shrubs, rocks, and the sun and how they all play in the space. Are there shade in some areas, ditches that may wet some spots, and do you get morning sun or the hot afternoon sun? All of these details will affect your garden in different ways. 
How is the soil? Getting a soil test done can be very helpful. It can help you understand the health and fertility of your soil to fix any nutrient issues. Your goal is to have a healthy soil environment with maximum plant growth. 
Plan out the irrigation for the vegetable beds. If you currently have an irrigation system make any adjustments that you need to make before planting seedlings or sowing seeds.
Sketch out your space. Draw the beds, pathways, gravel, arches, seating area, etc. 
Plan out what you are planting in each bed and the space it will take up in each bed. Understanding the spacing between the plants is helpful. Many websites can help you figure out the spacing for each type of flower and vegetable you will be planting.  
Shop for what you need. Once you have everything you need, you can get to work by building, fixing, planting, and lastly, “letting it grow.”
