What is the Best NPK Ratio for Roses?

To understand what is the best fertilizer for your roses you need to understand what is actually in the formula.  You may see a combination of numbers that looks like this: X-X-X.

This is the N-P-K ratio and it tells you the percentage of essential nutrients in the fertilizer: Nitrogen, Phosphate and Potassium.  The remaining percentage is filling material.  Understanding these numbers is the key to finding the right fertilizer for your roses to help them grow properly at the right times. 

The term ‘balanced’ is used a lot when it comes to rose fertilizer but this does not necessarily mean that these numbers are all equal.  Roses will use these nutrients at different stages in the growth cycle so the needs of your plant may change as it grows and blooms.  A ‘balanced’ rose fertilizer usually means that the mixture is roughly even in the amounts of these three elements.  However, usually a higher level of Phosphate is preferred. 

In addition to this, you will need to consider whether you plan to use an organic or non-organic fertilizers as this will change the percentage and strength of the different elements.  Organic fertilizers are the most natural and will provide your rose plant with the nutrients it needs, making them better in terms of N-P-K ratios.  Non-organic fertilizers aren’t great for actually fertilizing your plant but they are better at protecting the plant from the elements and different diseases.  Some fertilizers allow you to combine them with others so you may find that the perfect mix is a combination of organic and non-organic to provide your rose plant with adequate nutrients as well as proper protection.


When Should You Fertilize Your Roses?

The key to successfully growing an impressive rose bush is making sure that you fertilize it at the right time.  This can make all the different in terms of how well your roses grow because they need the right fertilizers at the right time and at different stages of growing to make sure they are properly supported.  This section of our guide will walk you through the proper feeding schedule for a rose plant so that you can create your own schedule based on the growth state of your plants. 

Fertilizing roses is a fairly simple job as they only need to be fertilized in the spring and early.  The key is never to fertilize in the later summer or in the autumn because this will promote new, softer growth which will be killed by frosts.  Fertilizing when its earlier allows your roses to absorb the nutrients and grow at the right time to be able to withstand the colder months to come.


How do You Fertilize Roses?

There are many ways that you can fertilize your roses.  This guide alone has three different ways to give your plants fertilizer to ensure that they get the best support when they need it.  Of course, there are pros and cons to each method of fertilization so it is important to understand what your roses need, when they need it, but also what method of fertilization suits you best.  The three different methods of fertilization will be discussed here so you can better understand which might be the right one for you and your roses.

Soil

A soil based fertilizer is a great option because it surrounds your rose plant with nutrients at all times and these nutrients are further released when the plant is watered.  This means that you don’t have to apply the fertilizer as often as you would a liquid, since the plant is constantly sitting in fertilized soil.

The main drawback to soil based fertilizer is that it is incredibly smelly since it is usually made from manure.  This can attract flies which can damage the plant should they produce larvae.  It is also more time consuming to apply since you will have to remove and replace the soil in order to attain the same level of fertilization.  However, you will not have to do this very often.

Granules

Granules are much more low-maintenance if you want a consistent supply of fertilizer for your roses.  They provide sustained and consistent fertilization and are usually slow release so that the roses are in a constant supply of nutrients.  They are also very easy to apply as you simply place them around the base of the plant or push them into the ground if they are in a spike, which is much less messy than soil or liquids can be.

The main drawback to granules is that they do not provide for an even coverage of nutrients.  They will only emanate from the area the fertilizer sits.  This means that Potassium may not successfully reach the plant roots very often as it needs water to mobilize.  They can also be very strong and this may harm the plant through burning.

Liquid

Liquid is another very easy option for rose fertilization as you simply add a small amount of the fertilizer to water when you plan to water your plants.  This provides your plants with an immediate and even supply of nutrients across the entire root base.  Moreover, the water allows potassium to mobilize properly which gives your plant everything it needs at once.

The main drawback to liquid fertilizers is that they will need to be applied quite regularly as they dissipate into the soil.  Although not as messy as soil fertilizers, this can still be an issue for those with busy schedules. Ultimately, your choice of fertilizer comes down to the right choice for the gardener, as different schedules and capabilities will guide your choice.
