Roses are used in many different kinds of fertilizers.
Choosing the right one isn’t always easy but having the best plants and the most beautiful blooms is so critical.
Here’s what you need to know about picking the best rose fertilizer.
What Does Fertilizer Do for Roses?
All fertilizers are composed of three main nutrients and each has a special role to play in plant growth. They are:
Nitrogen (N).Nitrogen is an important component of plant proteins and contributes to dense, leafy growth. Roughly any process that occurs within the plant, including photosynthesis, new leaf growth, and pest protection, is important.
Phosphorus (P).This nutrient is involved in the metabolism of plants and is necessary to transmit energy. In addition to getting energy from the stem to the tips of the leaves, phosphorous is also required for the growth of root and flora, making it especially essential for roses.
Potassium (K).Potassium ‘s principal purpose is to help plants tolerate stress. It helps to control the pressure of water in and around individual plant cells and is important for root growth.
Nitrogen is a convenient way to look at it, phosphorus is for the roots and potassium is for the whole plant. The ratio of nitrogen to phosphorus to potassium (NPK) should be shown on the side of the box when purchasing any kind of fertilizer.
The needs of roses with fertilizers differ throughout the year. They need a much different NPK ration in the spring as they reach the end of their blooming season than they do in the fall.
Finding the right balance over the growing season makes roses strong and improves bloom quality.
Spring
There are rose varieties that can thrive in just about any of the United States’ planting zones defined on the basis of the low average temperature. Dormancy and length of blooming season vary depending on the area but preparation for blooming should begin in the spring regardless of area.
For spring, it is recommended to use high-nitrogen fertilizer. Follow the packaging instructions but, in general, around 1⁄3 cup per plant is fine. Add to the soil at the plant base and rinse it in. The best time to add fertilizer for new plants is after you see about six inches of production.
Nitrogen, as we mentioned, is essential for plant growth, and just about every function within the plant. That’s why loading the soil up with it in the spring is so necessary. Do a monthly application of high-nitrogen fertilizer for 2 months in a row, normally in March and April, for better results.

Summer
As spring turns to summer, the requirements of roses for fertilizer change. They are getting ready for rapid growth in spring and they need a lot of nitrogen. They are getting ready to bloom in summer and need a more structured routine.
In the summertime, the best form of rose fertilizer has an even NPK ratio. That supports the production, energy, and overall health of plants. For every four feet of height per plant, use about 1⁄2 cup. Apply thoroughly to the foundation and wash in. Perform this once a month, beginning in May through August, for better performance.

This makes it easy to fertilize everything at once while making sure your roses get everything they need for big, beautiful blooms.
Late Summer/Early Fall
When the summer comes to an end, your roses’ needs change once more. They are heading into their dormant period in most climates so they don’t need new growth.
The fertilization strategy is essentially the opposite of what it was in spring. That is, you should use nitrogen-free fertilizer. If nitrogen fertilizer is used, the plant may be prevented from dormant which could make it more vulnerable to the inevitable cold weather.
Ideal to have an NPK ratio of little to no nitrogen. Phosphorus and potassium will help next year’s roots grow strong and prepare the plant for cold winter.
Water-soluble fertilizer is best because it can travel to the roots easily through the soil. Perform one submission in September and one in October and then get ready for spring again before March.

Other Things to Consider
The type of fertilizer that is best for roses often has to do with the soil quality. In slightly acidic soil, roses grow best which can influence how effective any fertilizer is. If you have tried different fertilizers and find that nothing really works, then the next step is to get the soil checked.
Whether you want to use an organic or chemical fertilizer is another decision you need to make. Both are good and bad things.
Organic fertilizers are generally good for both plant and soil feeding but may require additional applications. Chemical fertilizers do not always have long-term effects on the soil but are often capable of preventing insect, fungal, and other plant diseases from damage.
Rotating chemical fertilizers is a smart idea, not only because they adapt the nutrients to the time of year, but also because chemical accumulation is less likely to occur. That could have long-term effects on the soil over time.
Organic fertilizers usually don’t cause a buildup of this kind because they’re just not as strong as chemical ones. Using a mixture of chemical and organic fertilizers is a good approach since you get all the benefits of each without having as many negative effects.
