If you want to produce thriving roses, you’ll need to grow them in the right soil conditions. So, will roses respond well to mushroom compost? 

Mushroom compost will be a good choice for roses. It is high in organic material, which provides the nutrients roses need to grow and bloom. It can be applied as a soil improvement, or used as a mulch. 

Roses can be a bit particular about the type of soil they are grown in. Keep reading to learn more about what conditions they need and whether mushroom compost will be able to provide it. 

What is Mushroom Compost? 

Let’s start by looking at what mushroom compost is and some of the characteristics that make it unique. 

There are a few ingredients that comprise mushroom compostOpens in a new tab.. These include: 

The exact mix of these ingredients will vary, depending on the company making the compost.  Generally, the compost will be steamed. This will kill any bacteria or weeds, so it’s safe to use in the garden. 

Benefits of Mushroom Compost

As you can imagine, one of the things that set this type of compost apart is the high amount of organic material it contains. This gives the garden plenty of nutrients. Even better, these will be slow to release. So, it will be able to support plant growth over the long term. 

Plus, it will be able to increase the amount of water that is being stored in the soil. This is a good way of preparing plants for drought conditions. It can also reduce the amount of time that you need to spend watering the plants. 

Another reason why mushroom compost has become so popular is that it protects the soil from the heat of summer. Plus, it will protect the nutrient-rich topsoil from erosion. 

It will have a pH level of 6.9Opens in a new tab.. This will benefit most plants. According to the University of Vermont, most plants need a pH of 5.5 to 7Opens in a new tab.. Because of this, mushroom compost will be suitable for most plants. 

Downsides of Mushroom Compost

One of the biggest downsides of mushroom compost is the high salt content. This can cause problems for some types of plants. For example, it might stop seeds from germinating. It might also cause some harm to saplings. It’s also best avoided for species that are sensitive to salty soil. 

Though this can be solved by allowing the compost to cure over the winter. This is a simple process. All you need to leave it sitting uncovered during the winter months. 

How Will Mushroom Compost Affect Roses?

While mushroom compost is primarily made to support the growth of mushrooms it can also be used on other plants. But will it be a good fit for your roses?  

Roses will love ground that is rich in organic matter. This is something that mushroom compost can deliver. It will give your plants the nutrients they need, releasing them over a long period for sustained growth.  

Even better, the mushroom compost will have the right pH level. Roses will need a pH of between six and 6.5Opens in a new tab.. Though they will be able to tolerate a little variation on either side. So, a pH of 6.9 shouldn’t cause any problems. 

As we’ll discuss, it can be especially helpful when dealing with poor soil conditions. In particular, it can help break up thick clay soil. Roses need to have soil that offers good drainage while being able to retain nutrients. This is something that mushroom compost can provide. 

However, high levels of salinity might damage your roses. This is a concern when using mushroom compost. But it will often take a while for it to present itself. 

The salt will damage the plants by pulling moisture from the soil. Over time, it can start to interfere with the photosynthesis process. If left untreated, this can kill your roses. There are a few signs that high salinity might be impacting your roses, they include:

  • Browning leaves. At first, this will start at the tips of the leaves. But as the soil continues to dry out, the browning will spread.  
  • Crust deposits. Sometimes, the salt levels can become so high that they form a crust on the soil. This can stop the water from getting through, accelerating the damage. 

If you are seeing these signs, your roses could be in trouble. They won’t be able to survive such high levels of salinity for long. The good news is that you might be able to solve this problem. The key is to flush the salt out of the soil. 

First, you’ll need to add some sulfur to the soil. This will dissolve the salt, so it will be easier to remove. Next, you’ll need to water deeply. You might need to add three to four gallonsOpens in a new tab.. Do this once or twice a week. Over time, the signs of high salt will fade and you can stop this process. 

Other Plants That Can Benefit from Mushroom Compost

While mushroom compost might be the ideal choice for roses, there are a few other plants that might benefit from this compost. These include: 

  • Trees and shrubs
  • Vegetable gardens
  • Herbs
  • Lawns that aren’t established
  • Helping improve seedling growth, as long as it’s been properly cured

It’s also common to use it as a soil amendment if you have poor soil conditions in your garden. It can be a good way of fixing clay soils that suffer from poor drainage. It will also attract earthworms and other beneficial insects to your garden. 

Tips For Using Mushroom Compost

Unless you are growing the roses from seed, there is no need to cure the compost first. There are a few steps to follow when adding mushroom compost to the soil. These are:

  1. Add compost. First, it’s important to spread the mushroom compost around your garden. You won’t need to use a lot to see an impact. To amend the soil, you’ll need to use a ratio of two parts soil to every one part compostOpens in a new tab.. 
  2. Mix it into the soil. You’ll need to combine the compost thoroughly. You can do this using a garden hoe. It should be noted that mushroom compost alone won’t be suitable for most plants, including roses. Because it is a heavy clay compost, there is a chance that it will cause root rot if not mixed with the soil properly. 
  3. Water and wait. It’s a good idea to give the compost a little time to settle into the soil. During this process, you need to give them plenty of water. After a week, it should be ready for you to plant roses. 

If the garden is already established, you can use mushroom compost like mulch. Simply sprinkle it over the roses. Remember to leave a little space around the stem of the bush. Then, give it some water. You’ll only need to use a few inches of mushroom compost. 

It’s best to add mushroom compost to the soil during the spring. This gives the roses the nutrients they need to grow and bloom throughout the growing season. Plus, it will provide some protection during the summer. While roses don’t mind the sun, the afternoon heat might cause some stress. 

Final Thoughts

Mushroom compost is known for being high in organic material. This will release plenty of nutrients while amending the soil pH to make them easy for the roses to absorb. Even better, it can be used to break up thick clay soil and protect roses from the summer heat. Because of this, mushroom compost is a favorite amongst rose gardeners.
