The manure breaks down slowly and releases its nutrients overtime so that water soluble ingredients such as potassium are added to the soil gradually and not washed away by the first spell of heavy rain as they are with chemical fertilizers. Phosphate, all of which are required for growing healthy roses. Soil as it is packed with energy and contains phosphorous, nitrogen, potassium, Well rotted horse manure is particularly good for enriching

Leaf mould, well rotted horse manure, worm castings, grassĬlippings and compost are all good choices as they not only add nutrient butĪlso improve the soils structure and feed the soil’s ecology. Mulching as Fertilizer for Healthy RosesĪpplying mulch around the base of roses twice a year is the best way to maintain soil health and add nutrients to the ground organically.Īdding mulch to the rose bed is more about feeding the soil itself rather then directly feeding the plant, which in turn produces healthy, disease resistance roses. Organic, natural fertilizers such as alfalfa, fish emulsion, regular mulch and blood/bone meal are better for the environment as they, not only directly feed the rose but improve the long term health and fertility of the soil too. Natural, organic fertilizers act like a healthy balanced diet whereas chemical fertilizers are like multivitamins which provide a boost of nutrients but do nothing to stimulate the soil ecology and do not add to the long term fertility of the soil. Different organic fertilizers stimulate the soil ecology and provides all the nutrients roses need to grow strong and healthy with plentiful flowers. Therefore using a range of organic fertilizers on your rose bed delivers the best results.įor best results fertilizing roses organically you need a combination of fish emulsion, blood/bone meal and alfalfa applied every 4 weeks in the growing season and occasionally add Epsom salts to stimulate basal breaks. Roses are heavy feeders that require a broad spectrum of nutrients throughout the growing season to produce the best blooms.
