GreenStix contains a perfect blend of micro & macronutrients to ensure that you have happy and thriving house plants. This product is the most convenient way to provide essential nutrients for your potted indoor/outdoor plants. These sticks have three macronutrients-Nitrogen (N) which is essential for leaf growth and lush green color, Phosphorous (P) to help develop strong roots, and promote flowering and potassium (K) to help develop strong stems and fight disease. These fertiliser sticks also have micronutrients such as molybdenum, zinc, iron, boron, manganese, and copper which help in plant growth processes like photosynthesis, pigment production, growth hormone production, etc. The nutrients are glued together by a special organic binder. This allows nutrients to be gradually released into the soil, depending on the amount of watering. Replenish the green stix every 45-60 days. It does not need any other fertilizer or vermicompost fertilizer after you use GreenStix.
