Home Ask MG Organic fertilizers

PLEASE NOTE: In the autumn of 1995, we hatched the idea for a free, local gardening publication. The following spring, we published the first issue of Michigan Gardener magazine. Advertisers, readers, and distribution sites embraced our vision. Thus began an exciting journey of helping our local gardening community grow and prosper.
After 27 years, nearly 200 issues published, and millions of copies printed, we have decided it is time to end the publication of our Print Magazine and E-Newsletter.

Organic fertilizers

March 29, 2009   •   

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.
