The Rose Fertilizer Buying Guide

Fertilizer Grade

Before you decide to buy a good fertilizer for your rose bushes, you must understand why choosing the right one is so important. The fertilizer application is just as important for the rose as it is for any other plant in floriculture.

The feeding process dictates the quality and quantity of the roses that will be produced. The process also determines the look of the leaf color, stem strength, and longevity.

Fertilizers contain macronutrients and micronutrients, which are not easy for the plant to get directly from the soil. A good fertilizer is easily absorbed by plant cells.

Out of all the elements, the most important ones are deficient in the soil; nitrogen (N), phosphorus (P), and potassium (K). Nitrogen is essential in producing healthy leaves, phosphorus stimulates flowers and fruits, whereas potassium improves respiration and transpiration.

Fertilizer packages usually have a mixture of these elements; N-P-K. For example, if packaging shows 3:5:3, it means it has 3 parts nitrogen and potassium and 5 parts phosphorus. If you are looking for a fertilizer, which will improve root strength and flowering, then you should go for this one.

Apart from the above-mentioned elements, roses need calcium and iron. Calcium improves the resistance to pests and diseases by strengthening the cell walls. Iron works as a team with nitrogen to promote the healthy dark green color of the rose bush.

The product that has all the above-mentioned features is the Miracle-Gro Water Soluble Rose Plant Food!


Type of Fertilizers


Organic Fertilizer

Organic fertilizers are made of biodegradable materials and by-products of organic food. This type of fertilizer is made of natural ingredients including animal manure, dried blood, alfalfa meal, and cottonseed meal.

Gardeners who are concerned about burning their rose bushes can go for this type of fertilizer. Out of our extensive list, the fertilizer that is closest to being organic is the Dr. Earth Total Advantage Rose & Flower Fertilizer.


Inorganic Fertilizers

Organic fertilizers take time to break down, thereby, a considerable time has to pass before the elements become available to the plant. To speed up the process, synthetic or inorganic fertilizers are preferred.

Common inorganic fertilizers are ammonium nitrate, potassium sulfate, and ammonium phosphate. It is easy to differentiate between organic and inorganic fertilizer.

The winner for the best inorganic fertilizer is the BlueGold® Rose Blend (Rose Food).


Important Information About Best Fertilizers for Roses

The timing to fertilize your roses is very important. Many gardeners follow the basic method of fertilization. This is normally done on the blooms of the summer season, with the first dose of fertilizer applied by the end of winter.

The fertilizer added at this point is high in nitrogen. This promotes shoot and leaf growth. The next fertilization process is repeated in early spring.

When the buds start to peek out, a fertilizer high in phosphorus is added. This promotes bright flowers.

The next round of applications is done in the 6th week. This depends on the climate and the type of soil you are growing your rose bushes on.

The application of fertilizers is not hard at all since commercial ones have instructions on the process. Additionally, one must not apply them just because they feel like it. You must first assess the quality and fertility of the soil.


Fertility of the Soil

You must test your soil for its nutrients as well as the pH. Roses are known to grow best in soils with pH ranging between 6.5 and 6.9.

This makes the soil slightly acidic, which is important as fertilizers can add to the acidity. If this is not considered, the plant will have slow growth or difficulty absorbing important nutrients.

By testing your soil, you get a better know-how about the type of fertilizer you should use. Fertilizers come in different grades and the packaging can help you identify the right one for your rose bush.

By getting the right fertilizer you can amend your soil.


Deficiency of Nutrients

Normally it is easy to observe nutrient deficiencies by the appearance of the rose flower, specifically the leaves. If the leaves of the flowers are yellowing, it means they lack nitrogen.

Greyish leaves denote a lack of phosphorus while deficiency of potassium makes the margins of the leaves brown.

Depending on the symptoms observed, you should choose the recommended fertilizer. However, you must ensure that other reasons for the plant exhibiting this behavior do not exist. Sometimes, the plants are infested with pests so check for any signs of them.



Choosing the right fertilizer can make or break your entire journey of growing rose flowers. Since these flowers are marketable and have a strong history to them, you will find a lot of fertilizers that will cater to your gardening needs.

However, choosing the right one can be cumbersome. That’s why you must test your soil and read the label to add the missing pieces to the puzzle. Our list of 10 best fertilizers for roses should give you a good idea of what you should choose. Get started today!
