What Should I Feed My Roses With?

What Should I Feed My Roses With

To promote the optimum growth and health of roses, it is important to feed them with the right amount of flower food. This involves the application of plant chemicals and nutrients that will aid in the significant development of stalks, petals, and roots.

Examples of the nutritional ingredients that flowers need include nitrogen, phosphorus, and potassium (NPK).

  • Nitrogen – It is essential as it induces the healthy flourishment of leaves which, in return, would lead to the graceful blooming of rose petals.
  • Phosphorus – It is necessary to enhance the growth of roots and to increase the production of flowers.
  • Potassium – It is equally vital in helping the roses recover from extreme stress brought by plant pests, diseases, and unpredictable weather conditions.

Not only that, but roses also need other indispensable plant nutrients such as boron, copper, iron, magnesium, manganese, calcium, zinc, and sulfur. These plant ingredients must be applied in the correct dosage. An excessive or underwhelming application of fertilizers would cause the fast wilting of leaves, a lesser number of blooms, easy falling of stalks, and stunting of plant growth.

These rose fertilizers are either organic or synthetic in nature.

  • Organic sources: Compost tea, manure, alfalfa pellets, and fish emulsion.
  • Synthetic products: Made from a mixture of commercial and organic ingredients.

Which NPK Is Best for Roses?

One of the best NPK options for roses is the Organic Liquid Fertilizer for Flowers & Fruits from the brand PetraTools Solutions. It exclusively contains organic ingredients, namely corn, seaweed, and American Fish.

These ingredients play a big role in the nourishment of flowers and fruits, quick growth of beneficial microorganisms, and healthy condition of soils. Thus, it is safe to use around a wide variety of plants and herbs as it does not contain harmful or strong chemicals.

Other than that, it offers results in just seven days as its fast-acting formula can abruptly stimulate its controlled digestion process. This will lead to an easy breaking down of nutrients and their quick absorption to plants.

Choosing the Best Rose Fertilizer

Choosing the best fertilizer is a vital step in taking care of rose plants. In selecting the ideal plant food, it is important to consider the fertilizer with the perfect ratio of nitrogen, phosphorus, and potassium (NPK).

NPK are the main components of every rose fertilizer, so the amount of each of these ingredients must be carefully balanced. This is because the excess or lack of any of these substances will lead to lesser petal blooms, yellow discoloration of leaves, and slow plant growth.

It is also important to decide between organic and non-organic types of fertilizers. Those made from organic ingredients can sufficiently supply the rose plants with the needed nutrients while uplifting the quality of the soil. On the other hand, non-organic fertilizers can also provide the required nutritional value, but there is a lesser effect on the soil quality. 

What Is the Best Time to Fertilize Roses?

When a rose is newly planted, it is advisable to use only phosphorus, as it will induce the development of roots. Once the petals start to bloom, you can add other kinds of fertilizer to further strengthen their growth.

On the other hand, the time interval for the fertilization of established roses may depend upon the season.

  • From early to mid-spring, it is recommended to apply plant food when the new leaves start to sprout.
  • In the late summer to early fall, it is important to stop the application of fertilizers six to eight weeks before the average frost as it will cause damage to the new plant growths.
  • For the rest of the seasons, continue to put rose fertilizers every two to four weeks, especially during its growing period.
