I want to use only organic fertilizers on my garden. What should I use on my annuals to achieve the best blooms? What about my perennials?
All plants need a proper balance of nutrients to grow and flower well. The major nutrients, nitrogen, phosphorous and potash are required in the largest amounts by plants. Nitrogen is regarded as the most important element for healthy foliage production. Phosphorous is essential to strong root development and flowering. Potash strengthens stems and roots, contributes to disease resistance and winter hardiness. Many minor nutrients such as iron, manganese, zinc, etc. are equally important, but used by plants in much smaller amounts.
The point to remember is that a balance of nutrients is essential to good plant growth and flowering. There are many balanced, organic-based fertilizers on the market that would work well. They can be worked into beds when turning the soil in the spring and can be used monthly during the growing season. Foliage applications of liquid seaweed will help supply additional minor nutrients.
