Do Roses like Acidic Soil?

Roses prefer acidic soil. A pH between 6 and 7 is ideal, with a pH of 6.5 being the best. The soil should not be too acidic (lower than pH 6) or too alkaline (8 higher than pH 8) as the roots will have trouble absorbing nutrients and will most likely cause the rose to die.

Garden soil with regular mulch applications will be
Due to the fact that most organic matter is in the range of 6-7 acids
decomposed can be either pH neutral or slightly acidic, which is ideal for roses.

Soil can be very acidic or alkaline.
Therefore, it is not suitable for growing roses.

Check the soil pH before you plant roses in new areas of your garden.

How To Test Your Soil pH for Rose Growing

Roses can be costly so it’s a smart idea to buy them.
Before planting, determine the pH of your soil.

The best way to test the soil is to use a cheap kit.

A soil test kit is the best and most reliable way to determine whether you are getting the right type of soil.

A pH of 6-7 is ideal for rose planting.
If your soil is too alkaline (pH 7.5) or too acidic (pH 7.6), you should test it.
You will need to amend the soil (pH 6 and lower) before you plant.

Maintaining The Right Soil pH for Roses

Once your soil is at the ideal pH, it’s easy to maintain it. If you have a regular routine of mulching your rose beds, it will be easier.

Adding mulch to rose beds can have many benefits, including increasing fertility and improving drainage. It also retains water and cools the root system during the heat of summer.

But it is important to make sure that the compost has been properly rotted after it has been fully incorporated.
The perfect solution is to decompose it in a slightly acidic or neutral state.
Conditions for roses

To maintain roses’ optimal soil pH, mulch should be added to rose beds at least twice per year.

The first mulch application should be made at the beginning of

The second application should be made in September for the summer months.

to establish over winter.

Apply the mulch to the rose base in a 2-inch thick layer. However, you should keep it at least 6 inches from the rose canes.

If rosewood that is higher than ground is exposed for extended periods to moist material, it can cause wood rot. Allow some bear ground to be placed between the mulch and rose canes.

The mulch should not be buried in the ground. This could cause damage to the roots and disrupt the soil ecology.

Always spread mulch on the surface. Microbes and earthworms will naturally incorporate the mulch into the soil.

To maintain soil pH, I recommend that you use a mulch that is quick to decompose. This includes garden compost, leaf mold or horse manure. It will become part of the soil and can be used over the year to keep soil conditions in a good place.

I would not recommend using organic material that takes too long to decompose, such as pine needles or wood bark.

These types of mulches take longer to decompose and can be difficult to incorporate into the soil for years. They have less impact on maintaining the optimal pH of your roses.

How To Modify Alkaline Soil for Roses

If your garden soil is especially alkaline (if it has a pH of

  • Remove soil contaminating with ericaceous material.

Ericaceous soil is available at garden centres (and
amazon) and has an acidity around pH 5, which will help to rebalance.
Particularly alkaline soils.

It is rare to find soils with high alkalinity.
It is more common to find slightly alkaline soils with pH levels between 7.5-8.

If your soil falls within this range, the most effective treatment is possible

  • To add lots of organic matter to your rose
    You can lay it down and dig to a depth of 15 in.

You can add organic matter to the soil.
You can either manually dig it in or use a tiller, which requires less labour.

Once the garden compost has been fully rotted, it will either be pH neutral or slightly alkaline, which makes it ideal for roses.

Even acidic pin needles ,, which have a pH between 3-4) will once they are fully decomposed be at a neutral pH due to the ecology of soil.

Keep in mind the depth and origin of the rose’s root
So you can dig in your compost.
Or ericaceous compost up to a depth 15 in.

After you have applied the soil amendments, you need to test it regularly to ensure that the soil is within the right pH range for roses (between pH 6 and 7).

Give the soil time to settle before you test it. Continue testing the soil for three months to ensure it is in the right range to grow roses.

It is possible to convert an alkaline soil into slightly acidic soil by trial and error, as each garden is different.

As long you test your soil for any amendments and adjust your strategy accordingly, you will eventually have a balanced soil that is slightly acidic. This soil should be perfect for growing roses.

How To Amend Overly Acidic Soil for Roses

If you have determined the pH of your soil in your garden, it is
Below pH 6, you’ll need to adjust the soil to ensure that roots are healthy.
The roses can take up phosphates, potash, and nitrogen with ease.
For healthy growth and good flower displays, it is necessary.

Changing the pH of soil is a slow, continuous process.
This will mean that you’ll need to retest frequently.

There are two effective ways to increase soil pH.

  • If your soil pH is lower than 5, I suggest using garden lime to balance the soil’s acidity.

Garden lime can be purchased from Amazon and other well-stocked garden centres. In winter, garden lime should be applied to rose-planting areas.

Follow the manufacturer’s instructions. It is easy to accidentally overdose an area and then raise the pH too far beyond the alkalinity range (over pH 7).

If your soil pH is 5 or higher, then

is the best choice.

  • Add wood ash and compost to the rose-planting area. Then till or dug the compost into soil to a depth 15 in.

Woodash is naturally alkaline, so it can be used as a natural remedy for overly acidic soils. It is great to have ash from indoor fireplaces and bonfires, but it is best to avoid ash from charcoal or coal from barbecues. These substances can cause soil damage and may pose a threat to soil structure.

Garden compost can also be pH neutral (if slightly acidic), so it will help decrease acidity, add fertility, improve soil structure, and stimulate soil ecology. This will all promote healthy rose growth.

Mix 2 cups of wood-ash and compost together, then dig the mixture into the soil to a depth 15 in.

You must dig the amendments in the soil to the depth indicated. This will allow for the full maturity of the rose’s root system.

Leave the soil to ferment for at least a month before testing. I recommend that you test the soil once a month for 6-7 pH. Then, plant your roses.

Removing soil that is too acidic is not an exact science. It requires trial and error and constant testing for three months.

If you’re unsure, you can always add ordinary garden compost to balance your soil pH.


Key Takeaways

  • Roses thrive on slightly acidic soils. They can absorb the nutrients that they need to thrive, and they produce beautiful displays of flowers. You can make acidic soils more acidic by adding wood ash or compost. If the soil is too acidic, adding compost and ericaceous soil will help to balance it. This will produce a soil that is more neutral or slightly acidic.
  • Maintaining the pH of the soil so it is suitable for growing roses long term can be achieved with regular applications of mulch in the early spring and before winter although mulch can be applied at anytime of the year.
