How To Choose The Best Fertilizers For Roses?

Spikes vs. Granules

  • Spikes
    • The easiest-fertilizer-to-use must be spikes. Since all the nutrients will be continuously released over time, at least 2 months and longer, all you have to do is to insert the fertilizer spikes around the drip line several times per year.
  • Granules
    • Granules are an easy-to-apply type. Just sprinkle the right amount of the product around the plant base to the drip line and water them with a watering can or a garden hose.

Organic Vs. Non-Organic Fertilizers

  • Each type of fertilizer has its own pros and cons, so your final decision between these two will largely depend on each user’s personal preference. While organic fertilizers not only provide the rose bushes with all the required nutrients but also assist in improving and maintaining the quality of the soil where they are rooted, non-organic fertilizers can meet your plants’ nutrient requirements but will do little to create the perfect environment for their optimal growth.
  • Though non-organic fertilizers are not organic in nature, they have a lot to offer. Some even contain several chemicals for protecting the rose bushes from both insects and diseases. To balance out the lack of minerals or synthetic soil-enriching chemicals, it is advisable to apply organic materials into the soil when you use non-organic products.

Fertilizer Analysis

  • A quick note here about the fertilizer analysis printed on any fertilizers for roses: the N - Nitrogen is for upper (bush/plant top new growth), P - Phosphorous is for lower (good for strong root growth and making seeds, flowers, and fruits) and K - potassium is for overall (good for strong stems as well as the entire plant or bush systems). All of these three primary nutrients are well mixed together to keep the rose bushes healthy and increase their productivity.
  • Each plant variety might need a specific level of these three elements, but roses tend to grow best with a roughly even NPK mixture.
