Time to think about feeding those hungry rose shrubs. In my own yard, I have used bad things in the past (wont do that any longer) like systemic feeders with pesticide control included, top dressed with my own compost, epsom salt, Rose tone. But this year I am looking for a really good rose feeding program for both my own garden and two public gardens I am involved with and need to fertilize in good conscience. One public garden has a 25 yaard hedge of Knock Out roses that I planted about 6 years ago, and another garden has very old Fairy roses.
What are the forum readers using to fertilize roses organically?April 10, 2010 at 1:51 pm #29337
Hi thymely lilies,
I have about 30 roses and what I use is Dr. Earth and apply it about 3 times a year and use alfalfa meal twice a year. But like I said I only have 30 roses, so I’m not sure how cost would be for the Dr. Earth. I would also think about using compost tea. Also according to a Martha article she states for organic gardening, to use fish emulsion, cottonseed meal, processed kelp, or blood meal weekly.

Applying fertilizers, organic or inorganic must be dealt with caution. Although its organic, it does not mean applying too much of it will not damage our plants. We have to understand the basics of what are plants need on a case to case basis. Although we have a general purpose fertilizers, which consist of all the three nutrients needed for plant growth, we need to understand what kind of fertilizer to apply for a specific purpose. Like if our plants is on its growing stage, we must not apply a general purpose fertilizer, hence we must apply a nitrogen base fertilizer that is much need for plant growth. The three following chemical compounds may give you an idea of what plant nutrients are needed for specific plant development:
 Nitrogen – This is the main nutrient for new green growth. This is especially important for plants that are mostly all leaf such as grasses. As a result the ratio for lawn fertilizers has a higher 1st ratio number meaning more nitrogen in the mix.
 Phosphorus – This nutrient promotes good root development and strengthens the flower or plant. It also results in increased blooms on flowers so lots of phosphorus is great for bulbs and perennials. Fertilizers higher in phosphorus have a higher 2nd number in the ratio.
 Potassium – This builds strong and healthy plants & flowers and improves the overall health of the flora.
Based from that, you can plan your fertilizer application all year round. best of luck.
