Take a look at everything you need to know about rose fertilizer below, or skip ahead to the frequently asked questions.
Type Of Fertilizer
One of the most important factors to consider is which type of fertilizer you would like to use in your garden. There are three main types of fertilizer to choose from: liquid fertilizer, pellet fertilizer, and granular or powdered fertilizer.
Liquid fertilizer needs to be diluted before you can use it on your rose plants. You will need to add the correct measure to your watering can, then top it up with water. Make sure to give this a thorough stir before you then water your plants.
You should also ensure that you water the soil around the roots of the rose plant, and not the plant itself. Any fertilizer that gets on the leaves of your plant will burn it.
Pellet fertilizer is one of the easiest types to use, and therefore one of the most popular. All you need to do with these is sprinkle them onto your soil. These are usually more environmentally friendly than other types of fertilizer, and will release their nutrients into the soil slowly.
Granular and powdered fertilizers are similar to the two forms we’ve mentioned above. Granular fertilizers can be sprinkled directly onto the soil of your rose plants and will then need to be watered into the earth. Powdered fertilizers will need to be watered down before you can use them.
The best fertilizer for your needs will fully depend on which type of fertilizer you prefer to use with your roses.
Easy To Use
You will want to select a fertilizer that will be fairly easy for you to use. This will include an easy to follow set of instructions. There’s no point in opting for a fertilizer that is going to be too complicated for you to use, as this will make the process of fertilizing your plants more strenuous.
Think about several of the factors that we’ve mentioned on this list. Do you have a preferred type of fertilizer? Do you want a fertilizer that instantly releases nutrients that you might have to apply more than once?
All of these factors and more will culminate in deciding how easy your chosen fertilizer will be to use on a regular basis.
Instant Feeding VS Slow Release Fertilizer
Another important factor to consider is whether you should opt for an instant feeding or a slow release fertilizer. Both will have their advantages and disadvantages.
Instant feeding fertilizers will immediately release the nutrients your roses need into the soil. So your roses will get an instant feeding to encourage them to grow healthy blooms and a stronger root system.
However, these typically don’t last for very long. You will likely have to reapply the fertilizer every week or two in order to ensure that your roses get the nutrition they need.
A slow release fertilizer will gradually drip feed these nutrients into the soil over a period of a couple of months. How long the fertilizer is able to do this will vary from product to product.
So this will slowly give your roses a constant feeding, meaning you only have to apply this once or twice over the growing season. However, it does mean that it will take even longer for you to see results.
Organic VS Synthetic Fertilizer
One of the most important decisions you will have to make is whether to choose an organic fertilizer or a synthetic fertilizer. Both come with advantages and disadvantages.
Organic fertilizers are often the more preferred type of fertilizer. These will encourage happy and healthy blooms, and often yield better results.
They are also more environmentally friendly for your garden than their synthetic counterparts. However, this type of fertilizer is usually more of a slow release type. They can sometimes be more expensive depending on the product you choose.
Synthetic fertilizers are much cheaper to produce. They often also deliver much quicker results. They can also be cheaper, depending on the product you choose.
However, they can sometimes feature nasty chemicals which could be harmful to the environment. These can cause fertilizer pollution, especially if there’s a lot of fertilizer runoff.
Promotes Soil Health
It will also be a great idea to look for a fertilizer that works to promote the health of your soil. This will not only benefit your soil in general, but it will also be more beneficial for your roses. If your roses are planted in healthy soil, they will be much happier.
Look for a fertilizer that contains beneficial microbes. This will help to improve the health of your soil as well as encouraging healthy roses.
Frequently Asked Questions
When To Apply Rose Food
Knowing when to apply rose food to your plants will entirely depend on the roses you have in your garden. Most varieties will need feeding twice a year.
The first feeding time will typically be around spring. You should be able to tell when your roses need to be fertilized when the leaves are nearly completely open.
It’s also advised to mulch your soil after you have fed the roses, as this can further improve the quality of the soil, which will in turn encourage the roses to produce the best blooms.
Once the first flowers have finished blooming, you will have to apply a second feed. This can encourage your roses to produce more flowers, providing they are a variety that is able to produce flowers more than once a season.
Remember not to overfeed your roses, as this can cause your plants more issues than actually helping them. This will encourage them to produce more leaves than flowers, for one thing, so you won’t get the beautiful blooms that you’re after.
How do you apply rose food?
Knowing how to apply rose food to your plants will depend on the type of product that you opt for.
Powder and granular fertilizer will need to be sprinkled over the soil around your rose plants, which are then watered into the ground.
Most powder fertilizers need to be diluted before you apply them to your plants, otherwise you could burn them. It will be best to take a look at the packet instructions before you use this.
Liquid fertilizer will also need to be diluted before you can apply it to your plants. Simply measure out the correct amount of liquid fertilizer into a watering can, then fill this with water.
Give the fertilizer a good stir using a stick so that it spreads evenly through the water, then water your roses.
Don’t get the fertilizer on the leaves otherwise this will burn them. You should always apply the fertilizer to the soil around the roots of the plant, as this is where it is needed. You will find that liquid fertilizer works much quicker than pellet or granular fertilizer.
Pellet fertilizer is one of the most popular types of fertilizer for use with roses. These can be sprinkled around the roots of your roses on top of the soil.
They are also one of the more environmentally friendly types of fertilizer. These slowly release the nutrients into the soil, and can help improve the health of the soil itself as well as your plants.
Remember the golden rule – fertilizer is best applied to the top of the soil where your rose plant’s roots are located. If you do accidentally get fertilizer on the plant itself, make sure to wash this off so your plant doesn’t get burned.

What is the best time to fertilize roses?
It will be best to fertilize your roses during early to mid spring. The best way to know when you will need to fertilize your roses is when they start to sprout new leaves.
It’s important to remember that when you need to fertilize your roses may also depend on the cultivar that you have in your garden. This is because some varieties of roses actually flower twice a season.
If you have one of these roses in your garden, you will need to fertilize them once the first flowers have started to die off.
What happens if you over fertilize roses?
If you use too much fertilizer on your roses, it could actually damage them rather than encourage them to grow healthily. This can cause yellow or brown discoloration in the leaves as well as damage the root system itself.
If you leave any fertilizer on the plant itself, this will burn the leaves. You will also notice that your rose plants start to grow very slowly, and there won’t be the flourishing of blooms that you were expecting.
It should be fairly easy to see if you’ve over fertilized your roses. You will be able to spot a slight crust of the fertilizer on the surface.
It will also be quicker to spot these symptoms if you have used an instant release fertilizer. If you have used too much slow release fertilizer, you should notice the symptoms of over fertilization in a couple of weeks’ time.
