After your seeds have germinated, it’s time to properly care and maintain your seedlings to ensure healthy growth and easier transplanting. Light, water, ventilation, fertilization, and thinning are 5 key steps we will talk about. In the video on "Containers and Potting Mix," we sowed broccoli seeds into 3 peat pots. In this video, see how these seeds have grown over the past few weeks. Which ones are doing well? Which one failed? What factors might have caused these results? What do plants need to survive? Light, water, air, soil. These are all questions you can ask your students as they watch their seedlings grow. Watch the video to explore these questions further.
