When one brings up the topic of soil for roses, there are some definite concerns with the makeup of the soil that make them their best for growing rose bushes and having them perform well.

Rose Soil pH

We know that the soil pH is optimum at 6.5 on the pH scale (pH range 5.5 – 7.0). Sometimes the rose soil pH may be either too acidic or too alkaline, so what do we do to effect the desired change in the pH?

To make the soil less acidic, the common practice is to add some form of lime. Typically, ground agricultural limestone is used and the finer the particles the more rapidly it becomes effective. The amount of ground limestone to be used varies with the current soil makeup. Soils higher in clay will typically require more of the lime additive than those lower in clay.

To lower the pH level, aluminum sulfate and sulfur are typically used. The aluminum sulfate will quickly change the pH of the soil for roses where sulfur will take longer, as it requires the aid of the soil bacteria to make the change.

For any pH adjustment, apply the additives in small amounts and test the pH at least a couple of times before adding any more. Amendments to the soil will have some effect on the overall soil pH. We need to keep this in mind and keep an eye on the pH level. If the rose bushes start to change in their performance or even have an overall change in natural foliage coloration or natural shine, it could very well be an out-of-balance soil pH problem.

Preparing Soil for Rose Bushes

After considering the soil pH, we need to look at the beneficial micro-organisms in the soil. We must keep them healthy in order for the proper breakdowns of the elements that provide the food for our rose bushes to take up. Healthy micro-organisms will crowd out pathogens (the disease making bad guys…) in the soil by competitive exclusion. In the process of competitive exclusion, the beneficial micro-organisms reproduce themselves quicker than the bad ones and sometimes even feed upon them. Keeping the micro-organisms happy and healthy will usually involve adding organic materials/amendments to the soil. Some good amendments to use for rose soil preparation are:

  • Alfalfa meal – Alfalfa meal is a good source of nitrogen and is nicely balanced with phosphorus and potassium, plus it contains Triacontanol, a growth regulator and stimulant.
  • Kelp Meal – Kelp meal is a slow-release Potassium source providing over 70 chelated trace minerals, vitamins, amino acids, and growth-promoting hormones.
  • Compost – Compost is decomposed organic matter that increases microorganism activity and improves the overall quality of the soils.

These, along with some peat moss in them, are all wonderful soil-building amendments. There are some great organic composts on the market in bagged form; just be sure to flip the bag over to read what all is actually in that compost. You can also make your own compost fairly easily these days with the compost maker kits at local garden centers.

Roses prefer a rich loamy soil that drains well. They do not like to have their root systems in soggy wet soil, but cannot be allowed to dry out either. A nice, pliable, moist feel to the soil is what is desired.

Nature has a way of telling the gardener when the soils are good. If you have been successful at building rose garden soil, the earthworms come into the soil and are easily found there. The earthworms help aerate the soil, thus keeping the oxygen flowing through it and keeping the entire biological process in good balance, working like a well-oiled machine so to speak. The worms further enrich the soil with their castings (a nice name for their poo…). It is like getting free fertilizer for your roses and who does not like that!

Basically, a good soil makeup for roses is said to be: one-third clay, one-third coarse sand, and one-third decomposed organic matter. When mixed together, these will give you the right soil blend for providing the best of soil homes for your rose bush’s root systems. Once you have felt the texture of this properly blended soil, it should go through your hands and fingers, and you will easily recognize it from then on.

The Best Rose Fertilizers for Healthy and Vibrant Rose Plants

BobVila.com and its partners may earn a commission if you purchase a product through one of our links.

Like humans, roses require a healthy diet of nutrients to grow and perform well. However, just as popping too many vitamin pills causes humans to overdose on a good thing, excess use of chemical fertilizers causes soil to overdose on plant food and excrete polluting runoff.

To become fit and flourishing, both people and plants need nutrients from natural sources. The best rose fertilizers combine these nutrients with other essential elements to improve the condition of the soil, as well as feed the plants that grow in it. These recommendations can help you decide which type and brand of fertilizer might work best for your blooms.


Neutral pH

Roses prefer a soil with a neutral pH of about 7, but they can still survive in somewhat more alkaline soil. When the soil has a higher pH, however, they may suffer from micronutrient deficiencies, a problem that requires extra-rich soil, compost or fertilizer to correct. Before you plant rose bushes, perform a soil analysis with a soil test kit from a garden supply store. The test will tell you whether the soil is acidic or alkaline. If it's acidic, you can amend the soil with powdered limestone, wood ashes or oyster shells.


Rose Gardening Soil Preparation

People need healthy food to perform their best, and roses are no different. Roses flourish beautifully in the right conditions, and the proper balance of soil “ingredients” is important for growing rose bushes. While these flowers are not frail, caring for roses can mean a lot of preparation work before you get to enjoy their beauty. In fact, roses are plants that require a large amount of nutrients in the soil in order to grow large and colorful blooms. The most important thing you can do for you roses is to feed them right. Since roses gain their nourishment through the soil that they are planted in, this means that you should take extra care to make sure that the soil is prepared sufficiently to support healthy growth.

Here are some tips for proper rose gardening soil preparation.

The first step you need to take before planting is to dig up all the ground in your bed. You don’t want any hard soil left. By digging up the ground, you will have the ability to get the fertilizer well mixed into the soil and this will allow the nutrients to sink into all of the dirt. This means that no matter what direction the roots grow in, they will be able to reach food.

You want to make sure that the entire layer of nutrients reaches at least two to three feet. As your rose plant grows, its roots will reach deeper and deeper and this will make certain they are fed.

Your next step is to dig a one foot deep hole and lay the soil to the side. You can place it in your wheelbarrow or on a piece of plastic so that it can be re-added later. After digging the hole in the garden bed, the next step in rose gardening soil preparation is adding fertilizer. This can be in the form of compost, peat moss, or manure. You may want to consult a local greenery expert for advice on which fertilizers are available and useful in your area. Since climate can affect them, your fertilizer should be the one most potent in your area. Add around three inches of fertilizer directly into the hole you have dug in the bed. Start digging for another foot, mixing the fertilizer with the soil. This is the hole where you will place your rose plant, so you will want to make certain that the fertilizer and soil are mixed extremely well. After it has been mixed very thoroughly, it’s time to add the dirt from the hole back into the rose bed. Once the dirt has been replaced, add another three inches of the fertilizer over the top of the rose bed. To protect your roots and encourage their growth, also add some bone meal. There are also rose fertilizers especially designed for the soil of a rose bed, you may want add some now if you want. But the soil should be well prepared without it. After all these layers have been added, use a spade to mix them up a little more and rake the top of the roe bed smooth.

The next step of rose gardening soil preparation is the hardest one: waiting. You need to give the soil a few weeks to absorb all of the nutrients before planting your rose plant. This will ensure that your rose plant is being fed the minute it gets planted.

If you follow our rose gardening soil preparation tips, your garden will be ready for planting. And you rose garden is well on its way to success.
