Part of any gardening project that deals with seeds also deals with seedlings. All seeds started indoors will need to be transplanted but knowing when and how is the trick.
The reason for transplanting is multifaceted. The first reason is that it gives one the chance to examine their seedlings. Separating those you will keep from those that you will not saves time, money and resources. It gives one the chance to start over, if need be. Without this personal connection with ones plants, the health and wealth of your seedlings may not be apparent.
Transplanting seedlings furthermore creates plants with stronger roots. They no longer have to compete with their brothers and sisters for food or space. It also allows the plant to absorb as much solar radiation as possible, which improves the effence of photosynthesis or the plant’s food making process. Plants that can make their food without competition produce stronger stems and leaves. This equates out to a healthier plant that can produce more and is less susceptible to pests and disease.
