How to Blur Background in Lightroom 
Getting a dreamy blur background that will help to focus on the subject is not a challenging task. But if you are new to Lightroom, it will be daunting then for you.
Today, we will make that difficult task simple by breaking down three simple methods of blurring the background in LR.
Here we go.
Method 1. Blur the Photo Background Using Brush Tool in Lightroom
Making background blur with the Brush tool is the most accurate way. Here how you can use this tool to get the blurry effect.
Begin with importing a photo on which you want to apply the blur effect.
To import an image, go to File > Import Photos and Videos. It will bring you to a browser where you can pick the picture you want to edit.
Once you select the picture, tap on the Import option.
After importing the photo into the Library Module, it’s time to head over to Develop Module. From here, you can find every editing tool to control your retouching workflows.
You can find several adjustment tools from the top side of the editing panel. Pick the Brush tool from the top of the list and tap on it to activate it.
At the bottom, you can find different customization options to control how the Brush will bring changes to your photo.
Now, it’s time to fine-tune your adjustment brush tool. Move the Size slider from left to right to get what size brush tip you want to get.
Then, customize the Feather slider by moving it right to left or the opposite. It helps you to alternate the hardness of the brush.
The playing part comes. Play with the brush tool and draw the background with it to change.
To see which part of the background you are painting, tick mark the Show Selected Mask Overlay box.
If you paint the background accidentally, don’t feel sorry. You can erase the part. To do so, go back to the brush panel and tap on the Erase tool.
Then, adjust its hardness and softness and brush over the area where you don’t want the blur effect.
Go back to the Brush panel again and find the Sharpness slider. Then, move it right to left to blur your background.
Method 2. Make Background Blur With Radial Filters
Radial Filter is another great tool to blur the photo background in Lightroom. Though you don’t get better control over it, you can do the task effortlessly.
Import the image you want to edit by going File > Import Photos and Videos.
Select the photo and click on the Import button to open it in the Library module.
Switch to Develop Module and pick the radial filter.
Create a selection by clicking on the middle of the subject and drag it outwards to make a circle.
You don’t need to be super precise in this case as you can fix it later.
Adjust the selection you made by clicking & dragging the edges. If you fail to make the circle around, probably you aren’t in the center of your subject.
So, move the center pin by dragging and place it in the center.
Then, move the Feather slider from right to left or the reverse to enlarge or lessen the changing area. To see what area of your image you are painting, check the Show Selected Mask Overlay box.
Back to the adjustment panel and find the sharpness slider. Then, move it from left to right to apply the blur effect.
Method 3. Blur Background Using Graduated Filters
Using Graduated Filter is one of my favorite tricks to blur a photo background. Here how you can achieve the desire blurry effect using this tool:
Open the picture you want to apply the blur effect.
To import a photo, head over to File > Import Photos and Videos.
Then, select the image and tap on the Import button.
Go to the Develop Module and choose the third tool (Graduated Filter) from the Adjustment Tools.
Note: You can’t see any slider on the screen as you can customize this directly.
Once you activate this tool by clicking on it, now tap on and drag the part of the image you wish to blur.
When you click on the image, you can see three lines. Drag them from the frame’s outside edge toward the center. The graduated filters may be vertical or horizontal.
Adjust the three lines. The closer the lines will be, the harder the blur effects you will get.
On the other hand, the more apart the lines from each other, the softer the blur effect you will achieve.
Finally, return to the Adjustment tools panel and use the Sharpness slider. Move it from left to right to make your photo background blur.
