Like all plants, Common plantain requires essential nutrients for healthy growth. Key nutrients include nitrogen (N), phosphorus (P), and potassium (K), often referred to as NPK. Nitrogen promotes lush, green foliage, phosphorus supports root and flower development, and potassium strengthens the plant’s overall health and disease resistance. Additionally, trace elements like calcium, magnesium, and sulfur play crucial roles in maintaining plant health. Ensuring these nutrients are present in the soil will help your Common plantain thrive.
