Vegetable gardening specifically focuses on 4 points: soil, sunlight, water, and spacing! One of the most important necessities when planting vegetables, is the soil. The ideal soil is loose and crumbly. It should be able to hold water, but also be able to drain well. Secondly, Most vegetables need about 6-8 hours of direct sunlight per day. Sunlight is the key to growth, so make sure you are planting in a place that gets a lot of direct sunlight! Next, it is very important to create a watering schedule. Vegtables generally need 1-1.5 inches of water per week. It is important to not over water or under water them because that increases the risk of them dying. Tip: Morning watering is the best! Spacing is also very important. If you plant all the seeds right next to each other, chances are that none of the vegetables will make it through. However, if you space them apart properly, then everything should grow!
