Overview
Roses use a large amount of nutrients, especially repeat-blooming varieties so that they require supplemental fertilizer for optimum growth. Rose plants need different amounts of nutrients depending on the soil in which they are planted. They require all the three primary nutrients contained in a complete fertilizer-Nitrogen, phosphorus and potassium.
There are two types of fertilizers that work effectively for roses, that is: Rapid-release fertilizers and Slow-release fertilizers. Rapid-release fertilizers are optimal for established rose plants experiencing immediate stress from lack of nutrients. They provide a quick boost of plant food in the short term, usually requiring reapplication every two weeks or so. On the other hand, Slow-release fertilizers are actually the best fertilizers to use on roses; they are generally applied as a top dressing around the bases of rose plants. The best examples of slow-release are organic formulations which generally release lower concentrations of nutrients over a longer period of time.
Experts usually recommend applying the first round of a quick-release fertilizer when new growth begins during the spring. The second round of fertilizer should be applied after flower buds first set and the third round in mid-July. When using a slow-release using a slow-release fertilizer, apply the product just once when new growth first starts. Apply the fertilizer evenly around the base of the plant and water immediately after to help the nutrients soak into the soil.
There are many fertilizer products specially formulated for Roses. This article provides information on 20 best, tried and tested environmentally friendly fertilizer formulations for roses. Choose one and use as per the direction.
