As a new gardener, it can be difficult to know how far apart you should plant your seeds. In order to have them grow in ideal conditions, there needs to be a specific number of space between each crop. If they are planted too close together, it can cause them to grow improperly, so you want to make sure you study the different requirements necessary for growth. Luckily, the infographic, Square Foot Planting Guide, provides the number of plantings you can have per square foot. This is helpful so that as you are planting your next garden outside or in a grow tent, you can plan ahead. The infographic includes vegetables that vary from arugula to hot peppers and spinach.
