I have two small pothos plants purchased from one of the nearby nursery. The one I planted in soil in a mixture of organic manure, cow dung and garden soil directly by digging a small hole. And the another one I planted in a plastic jar filled with clear water. All this procedure I have done almost 1 month back, but still my plants in both cases are in the same stage of growth as they were on the day of purchase. I am taking well care, giving sunlight, proper cow dung and organic local manure but still they are not growing. Instead, they are on the way of dying. Please help and suggest me some helpful ways to make them grow and creep my bamboo wall of my room to ceiling.
All of the organic material you mention may have to much Nitrogen for you plant.
Here are some articles that will help you make corrections in the potting soil.
