Do Blackberries & Raspberries Like Acidic Soil? (Explained)

Sharing is caring!

Are your blackberry and raspberry plants not thriving as naturally as they are supposed to? Are you wondering whether or not to change or acidify the soil to mold to the preferable ph level of soil for blackberry and raspberry plants?

Do blackberries & raspberries like acidic soil?

Blackberry and raspberry plants like acidic soil. Blackberry plants like soil that has 5.5-7.0 ph level and raspberry plants like soil with a ph of 5.5-6.5. Acidic soil is good for them that provides nutrients in the soil however, both plants don’t do well in highly acidic soil. 

Both blackberry and raspberry plants will grow to their full potential if the soil’s ph level is at their preferred level. On one hand, blackberry plants like mild or neutral acidic soil, and on the other hand, raspberry plants prefer the soil to be slightly acidic.

However, you need to be mindful of the fact that both of these plants don’t like soil that is highly acidic or has high alkaline in the soil. In addition, both these plants will do well if the acidic level of soil is between 5.8 to 6.4 ph. 

What is the best pH for blackberries and raspberries?

Both blackberries and raspberries really do well in soil that has a lower ph level which means they like to grow in acidic soil. 

In addition, blackberry plants like soil that contains 5.5 and 7.0 ph levels and raspberry plants like soil that has a ph level of 5.5 and 6.5. 

Can you use vinegar to acidify soil?

A very natural way to acidify your garden’s soil is by the usage of vinegar. Vinegar is known for its properties that help to lower the ph level of the soil. 

In addition, vinegar solution is also a quick fix-up of ph level of soil as all you need to do is to use 1 cup of vinegar in a gallon of water and then use a watering can to pour the solution in the soil. 

How do you acidify soil quickly? 

Not always soil’s ph level will be preferable to the plants you are trying to plant and you rather need to do some amendments to the soil. Therefore, when it comes to acidifying soil in your garden or lawn, you will need to lower the ph level. 

Additionally, there are some organic and chemical ingredients that work effectively to acidify the soil such as sulfur, elemental garden sulfur, mulch, ammonium sulfate, acid fertilizer, vinegar solution, and peat moss. 

Moreover, natural ingredients such as vinegar solution and mulch can give you quick results when it comes to quickly amending the soil.

However, when it comes to prolonging the amendment of the soil acidity, then organic ingredients won’t suffice but using chemical fertilizer or ingredients can result in a long-lasting change in soil acidity. 

How do you acidify the soil for blackberries?

Blackberries prefer soil that has 5.5-7.0 ph levels. In addition, not all soil will have the preferable ph level of blackberries therefore, it is important to be knowledgeable about the ways of acidifying the soil. 

Identify the Soil PH:

Identifying soil’s ph level is a must and it should be tested way before plantation so that you are aware of the soil’s ph level and can detect whether to decrease or to increase the soil ph level. 

Acidify the Soil:

There are so many ways with which you can acidify the soil. If you want to use a natural vinegar solution, then all you need to do is to add two tbsp of vinegar to a gallon of water. Additionally, you need to pour the solution into the soil.

Alternative Options:

You can use a myriad of different organic and chemical ingredients in the soil to acidify such as leaf mold, elemental garden sulfur, mulch, ammonium sulfate, acid fertilizer, and many more.

However, you need to be mindful of the fact that you may need to fix or amend the soil more than once.

How do I make my soil more acidic for raspberries?

Raspberries naturally prefer soil that is acidic. Even if the area where you want to plant raspberries are not acidic, you can still do some amendments to the soil to acidify it. 

Identify the PH Level:

One of the first things you need to do is to measure the ph level and only then you can move on to the process of amending the soil for plants. 

Adjust PH Level:

After testing, if the ph level is higher, then you must need to lower the ph level which will make the soil more preferable for raspberries. 

Additionally, to lower the ph level, you can use tea compost, peat moss, vinegar solution, sulfur, coffee grounds, and so on. However, you need to give time to the soil to absorb the elements properly. 

Maintain the PH Level:

After amending the ph level, you also need to keep maintaining the ph level. Additionally, you also need to make sure to regularly add natural and chemical elements so that the effect will remain intact. 

How to test soil ph level at home?

If you want to plant something in your garden soil, one of the most important things to detect in this case is to test the ph level. Knowing the ph level of soil can help you to make better judgments. 


To test the ph level of soil by yourself, you will need a trowel, white vinegar, baking soda, and you will also need some plastic containers.

Soil Sample:

The next thing you need to do is to take an appropriate amount of samples from the place that you want to know the ph of.

Additionally, rather than taking the soil sample from one area, you should have a blended sample if you want to know the ph level of a larger area.

Detect the Acidity:

Now, you need to add ½ cup of water to the soil container and you also need to add ½ cup of baking soda to the mixture. Consequently, if the mixture starts showing reactions meaning starts frizzing, then this is the indication of acidic soil.

Detect the Alkaline Soil:

To detect the presence of alkaline ph, you need to add ½ cup of water and ½ cup of vinegar to the sample soil. In addition, if the soil has very profound reactions meaning if the solution fizzes, it is a firm indication that the soil is alkaline soil.

What can you add to make the soil more acidic?

You need to lower the ph level of the soil to make it more acidic and to complete this whole process, you can use several elements in the soil to acidify.  


Vinegar can be used very effectively in the soil to make it more acidic. Additionally, you should not use vinegar directly on the plants rather the vinegar should be watered down. 

Adjustment of soil acidity by vinegar solution is a quick process however, you need to do this regularly otherwise the effect will wear off. 

Aluminum Sulfate:

With aluminum sulfate, you can easily and very effectively lower the ph level of the soil however, you need to be careful while working with aluminum sulfate. 

In addition, you need to use aluminum sulfate around the plants to make it work better. You also need to add aluminum sulfate one year before fixing the soil as aluminum sulfate takes time to work.

Coffee Grounds:

Another natural way to acidify the soil is by using coffee grounds. Coffee grounds are known for acidifying the soil very quickly.

Additionally, you have to use the coffee grounds directly in the soil for making it work more effectively. 

Peat Moss:

With the help of peat moss, you can keep the soil’s acidity intact for a long time. Moreover, peat moss is very easy to find and doesn’t take a lot of time to install. Moreover, peat moss is organic and naturally amends/acidifies the soil. 

Do raspberries like coffee grounds?

Raspberries definitely like coffee grounds. Raspberries like acidic soil and coffee grounds can provide that acidity in the soil. Additionally, coffee grounds also provide organic compost, nutrients, nitrogen, minerals, and so on. 

Usage of coffee grounds in raspberry plants will also attract the earthworms which will help to cultivate the land. 

Do blackberries & raspberries like alkaline soil?

Blackberries and raspberries don’t like alkaline soil. When any areas’ soil is alkaline soil, it means that the soil has a higher ph. In addition, blackberries and raspberries prefer acidic soil and they thrive in that soil and won’t grow to their full potential if planted in alkaline soil. 

Final thoughts:

To conclude, both raspberry and blackberry plants need slightly acidic soil to abundantly thrive. Consequently, the ph level for both of these plants should be in the range of 5.5 to 7.0. Any change from this ph range should be modified accordingly.
