Roses add color and fragrance to any garden, but to get the most out of these plants, you need to understand how to prepare soil for roses. The best soil to use when growing roses is loam. Loam is about 50 percent air and water with the balance being made up of sand, silt clay, and organic material. You'll need to learn about the soil you have and how to alter it to get the most out of your roses.

    • Clay soil will hold water but does not drain well. It is usually highly alkaline and will need a lot of organic matter added to it. Adding gypsum will improve clay soil and ensure good drainage.
    • Sandy soil will drain well but requires frequent watering. It will also need to be amended with organic material.
    • Very organic soil is usually highly acidic and will have both good drainage and moisture retention. You may need to add lime to increase the pH level.
    EXPERT TIP

    "The best thing you can do for any soil is to add about 20-30% of the best compost that you can get, and mix it into the top layer."

  2. You can buy compost from garden centers or use grass clippings and leaves from around your yard. Till them into the soil in the fall or in the spring as soon as you can work the ground. Preparing the soil in your rose garden in autumn allows the material to decompose all winter. [2]

  3. With new rose beds, use a roto-tiller or spade to turn the soil in fall and again in spring. If you have existing roses, turn the soil over near the rose bush and loosen the roots as much as possible, but be caution not to damage the rose bush. [3]
  4. Pick up a handful of soil and squeeze it. Soil that is too wet sticks together while soil that is too dry crumbles. [4]
  5. The water should drain out in around 15 minutes. If it takes much longer or drains too fast your may need to add more amendments.
  6. This is the soil usually found in woods and forests. [5]
    • Test your soil with a home kit or send it to a soil testing lab in your area.
    • You can raise the pH level by adding lime if the soil is too acidic. If it is too alkaline, add garden sulfur. If your roses grow poorly and have yellowing leaves, it may indicate that your soil is too alkaline.
  7. A balance of 1:2:1 is best.
    • Phosphorous helps roses bloom. Avoid too much Nitrogen as it will cause more foliage growth and fewer blooms.
    • Alfalfa pellets, epsom salts, fish emulsion or manure are also good additions to the soil and will help your roses flourish.
  8. This can be expensive if you are creating a large rose garden, but the soil is already amended and ready to help your roses grow to their best potential.
