What Type of Soil Is Used for Roses?
Roses are beautiful and known for adding color and fragrance to gardens and lawns. However, these picturesque flower bushes have a reputation for being fussy and fragile. In order to get the most out of them, you will have to provide lots of attention and take special care of them. The topmost thing you must know regarding this is about the soil for roses.
Like most plants, roses also need specific conditions for optimal growth and a certain kind of soil. In fact, potting rose plants in their ideal soil mix can go a long way in terms of improving their performance. Since soil is so important for roses, in this post, we will discuss everything about what type of soil is used for roses and what the best potting soil for roses is. Let us get started!
What Kind of Soil Is Ideal for Roses?
Without wasting any time, let us first address the most crucial question of the post: “what type of soil is used for roses?” If any soil is well-drained, deep, and full of decayed organic matter (humus), roses can grow easily in it. However, when it comes to the best soil for roses, those that are composed of a medium to heavy loam percentage (minimum of 35cm) are the best.
Loamy soil types have the natural advantage of having nutrients and water retention. Also, they require little preparation. Therefore, when choosing soil for roses, look for a loam medium. This usually has nearly equal proportions of silt, clay, and sand. If the proportion of one of these is more or less, you can always use soil amendments to adjust them.
For instance, if you notice that the soil in your garden is more clayish, you need to give it an airy texture. For this, you can make use of organic matter like composted manures from cow, goat, or chicken, compost, peat moss, grass clippings, dried leaves, etc.
Alternatively, if you find that the soil is too sandy in texture, you need to make sure to use an amendment that will help it hold enough water. Again, for this, organic matter is the answer. Further, be it any kind of soil for roses, one thing that you can use for all is mulch. You only need to add it to the top layer of the soil, and you are good to go.
Do Roses Like Acidic or Alkaline Soil?
After the kind of soil that roses prefer for optimal growth, let us move on to the soil pH range for it. Does a rose plant like acidic or alkaline soil? If you are wondering the same, you are in the right place. Be it any kind of plant, pH plays a great role in their access to nutrients in the soil and various other things. When it comes to roses, they prefer a slightly acidic to neutral pH range (6.0 to 7.0).
While you take care of your roses, you need to ensure that the pH is in the ideal range. If it is off, no matter how much you take care of your rose bushes, you will never be able to obtain optimal results. Chances are, your roses are going to stay stressed. Luckily, you do not need to worry much about this.
The ideal pH range for roses as mentioned above is a soil pH that is very close to the ordinary garden soil – slightly acidic to neutral. This range can be obtained and maintained easily using some amendments, and regular soil testing. Another thing you must note here is that different species of roses need different pH ranges.
Therefore, you must always research the ideal pH range of your rose type. For instance, do you know what kind of soil and pH is best for knockout roses? These kinds of roses need soil that is perfectly balanced. It should neither be neither acidic nor alkaline. The pH range for them needs to be between 5.5 and 6.5.
How to Make Soil Acidic for Roses?
Now, you know what the ideal pH for roses is. However, what can you do if the pH is too high or low? How to make soil acidic for roses? Or how to make it less acidic? If you are looking for answers to these, we have them all. Let us begin with how you can make the soil for roses less acidic. In order to do so, the most common amendment you can use is lime.
By adding this to your soil, you can easily make it less acidic. The amount of this ground agricultural limestone that you need to use, again, depends on your soil’s type, initial pH range, and general soil makeup. If your soil has a high composition of clays in it, you will need to use more lime to lower the acidity of the soil.
Now, let us move on to how to lower the pH level, and make the soil acidic for roses. If you wish to do so, you can use aluminum sulfate or sulfur. The former is used when you need immediate results. While it can change the soil pH immediately, using sulfur needs patience. It will take longer as it needs the help of soil bacteria to change the soil pH range.
Further, as for how to apply any of these amendments, you need to be very careful. When you carry out a pH adjustment, use only small amounts first. Also, after each addition, you need to test the pH at that time. This way, you can easily obtain the desired pH range (6.0 to 7.0). Also, once you have the desired pH for the soil, you cannot ignore it completely. You will have to maintain it well.
What Soil Texture is the Most Suited for Roses?
If you are on the lookout for the best soil for roses, you need to ensure that it has a texture that can drain well yet hold enough moisture for the plant. As stated earlier in the post, loam soil is the best for this. Let us tell you why. Now, we know that this kind of soil is a mix of clay, silt, and sand. If you use only one of these as a soil base, you can never achieve the ideal soil texture.
A soil base that is only clay will hold water for sure. However, it will not be able to drain well. It will result in the roots becoming waterlogged and thus cause root rot. Further, if the soil base is only sandy, it is again a problem. In this case, the water will drain even before it is absorbed by the roots to function.
Thus, the perfect soil texture for roses is loose, loamy soil. If you are not starting out with this kind of soil, you will need to use certain soil amendments to make it of the desired quality. When using an area to plant roses, the first thing you ought to do is remove any large rocks and stones from there. Next, you need to determine the kind of soil there.
If it is clayey soil, the first thing you may want to do is add sand to it. However, do not do so to loosen the soil up as it will only result in turning your soil into a cement-like texture. Instead, you need to use organic matter for such soil. This can be in any form like composted manure, compost, leaf mold, etc.
Using organic matter in place of sand will not only help the soil with water drainage but also water retention. It is because as this organic matter decomposes, the soil that was earlier clayey is bound to loosen in texture. You can use the same method if your soil has too much sand in its composition.
How to Enrich Soil for Roses?
Now, we know what kind of soil texture and pH is needed for roses in general. However, what is the best soil for mini roses? Do they need soil that is different? What about the other rose species? While loamy soil is best for roses in general, every variety of them may have some unique requirements.
For instance, if you are planting mini roses, you can add peat moss to your well-draining, loamy soil. It will keep the soil light and assist in root growth. The peat moss that you have added here enriches the soil further. Depending on the kind of roses you are growing, you can use different soil amendments to enrich the soil further.
There are various fertilizers or special rose foods that you can add to the soil when planting roses. However, there is no fixed amendment that can enrich the soil for roses. After all, the soil you are using can be different from others. Thus, the best way to determine what the soil needs is to get a soil test.
You can also take your cue from the plants that are already growing in that soil. Depending on all this, look for mineral amendments that your soil needs. Of course, you can always use an all-in-one fertilizer. However, it will do the soil more harm than good, especially if the content of a certain soil mineral becomes toxic.
For instance, if your soil lacks phosphorus, look for a fertilizer that is specifically made for it. There is no use providing other minerals to the soil, as well. If you need an organic amendment, you can readily find phosphorus in the form of bonemeal. If the nitrogen content in the soil is replenished, you can add kelp or soy meal for nitrogen. Of course, organic matter works too.
Similarly, if your soil test indicates that it lacks sulfur and magnesium. For these two elements, you can readily use Epsom salt. Further, when you use any soil amendment to enrich, make sure to use it carefully. For instance, if you are using some salt as an amendment, use it with caution around leaves as it can burn them, especially on hot, sunny days.

How can Mulch Help Roses?
Earlier in the post, we mentioned that if you are looking for “what type of soil is used for roses,” loamy soil works best. However, be it any soil for roses, adding mulch to it is a great option while planting roses. Do you want to know why? Let us tell you. Once you know what the best soil for your rose type is, and have it ready, use it to plant your rose bush.
You have to spread this soil into the planting hole. Then, on the surface of the soil around the plant, you need to add a 2- to 3-inch layer of organic mulch. The purpose of this is as follows:
- Adding mulch on the surface of the soil around the plant will keep the roots cool.
- The organic mulch on the top layer can also help the soil retain moisture.
- Another great function of adding mulch on the surface of the soil is weed suppression.
While mulch can help roses to a great extent, make sure not to pile it against the stem. If this happens, it can lead to the rotting of the plant. Further, between too much mulch, gnawing rodents and insect pests can find cover and eventually harm the rose bushes.
How to Prepare Soil for Roses?
By now, we are sure you have your answer for what type of soil is used for roses. To sum it all up for you, roses grow the best in loamy soils as they have 50 percent air and water, and a perfect amalgamation of sand, silt clay, and organic material. Lastly, let us tell you how you can prepare your soil to reach these standards. Have a look:
Determine Your Soil Type
Firstly, you need to determine the type of soil you have in your garden. According to it, you can make amendments to get a loamy mix. For instance, if it is clay soil, you need to add lots of organic matter to it. Also, you can add gypsum to improve it and ensure good drainage. Further, if the soil is sandy, it also needs to be amended with organic material.
On the other hand, if the soil you have is very organic soil, you need to worry about regulating its pH level. Such soils generally offer both good drainage and moisture retention properties. The only problem is that they are highly acidic. For it, you can use lime, and readily increase the pH level of your soil.
Add Organic Matter and Aerate the Soil
Unless your soil is very organic in nature, you usually have to add plenty of organic material to it. For it, you can readily get compost from garden centers. Alternatively, you can also go for grass clippings and leaves as organic materials. Once you have added organic matter to your soil, you need to dig and aerate it. This is needed each season. If roses are already there in the soil, do this carefully without damaging the rose bush.
Keep a Regular Check on the Soil Texture and Ensure Proper Drainage
You also need to ensure that the soil is dry and friable always. For it, pick up a handful of soil in the palm of your hand. When you squeeze it, the soil should be too wet to stick together. Also, it should not be too dry to crumble too much. If the soil is too wet, you need to ensure proper drainage. For it, make sure your pots have drainage holes. For the ground, you can look for other amendments.
Maintain Soil the Ideal Soil pH Range and Add Soil Amendments
Another thing that you need to do is regulate and maintain a pH of around 6.5 (slightly acidic) for the optimal growth of roses. For raising the pH if the soil is too acidic, use lime. Similarly, if it is too alkaline, add garden sulfur.
Along with the pH, you also need to maintain the soil nutrients. A soil test is the best solution to determine what nutrients your soil needs. From NPK fertilizers to bone meal and blood meal, you can use any amendment depending on the test results.
If all of this seems like too much for you, you can always go the easy route. Instead of amending the soil, simply go for a bag of quality potting soil that is specially designed for roses. However, do keep in mind that this can be expensive, especially if you have a large rose garden.
Final Thoughts
So, this sums up all you need to know about what type of soil is used for roses. When selecting soil for your rose bushes, make sure that it has amazing water retention and drainage properties. Also, it should have all the nutrients needed by roses to thrive. Irrespective of whether you are making your own soil mix for roses or getting a pre-made one, these key points are sure to help you out. Happy gardening!
