What is fabric weed barrier?

If we take weed barrier fabric for example, it is usually a poly woven fabric which could stop the weeds from breaking through the fibers. 

On the other hand, it could allow the water to penetrate  through its surface. In addition to weed barrier fabric you could go with landscape fabric as well. 

How to build a weed barrier for your succulent gardens 

Take off all vegetation 

To start off, you could take off all vegetation including weeds, grass and the rest of other vegetation as well. 

You could utilize a garden hoe, shovel or any other tool to do this. continue digging until you spot the roots.

 it is important that you locate the roots unless chances are that they could spread when you use landscape fabric. 

When you are using a hoe, you need to do it much slower whilst bringing it down towards the ground and towards you. Whilst you do it, do it at an angle of 45 degrees.  

Instead of that, you have the option of killing those plants whilst using a non-selective or broad spectrum or even an herbicide. 

If you are using the herbicide, you need to use it depending on the instructions of the manufacturer. After that, give them some time and they would die in the meantime.

Clear and even the soil level

Go ahead with raking the area completely whilst using a steel garden rake. Here, you could take off any weeds which you could spot uprooted. 

Moreover, you could proceed with raking all the twigs and the rest of the other sharp elements. 

Get rid of all the loosened debris including the rocks so that you could make sure the soil surface is gentle and even. 

Lay the landscape fabric 

Make sure that you make the landscape fabric and the long dimension of the area tallies with each other and go hand in hand.

You could trim the material off the roll whilst using a sharp utility knife.  Consider that you require one row of fabric, then the best thing to do is to overlap them by 6 inches. 

If your fabric has sides that are contrary to each other, like one side is shiny and the other side is dull, you need to place it properly. 

if it is essential, you may temporarily weigh down the fabric whilst applying heavy substances such as stones etc. 

Staple it so that you could secure the fabric

Ensure that you have placed the fabric properly. After that, secure it with fabric staples whilst using a hammer or even a maul. 

Staple it every 10 feet in their edges and even on their interior areas. Further you may even cut their edges if it is essential too. 

You may plant through the landscape fabric if you wish too. If you wish to do so, ensure that you make an x shaped incision in the landscape fabric for each individual plant. 

You could use a scissor or knife to do this activity. Make the cut inwards from outside and make those incisions which would allow the root ball of the plants to fit perfectly.  

After you dig the hole, you could dump the soil into a tub instead of dumping it on the surrounding fabric. 

After that you could place the plants and fill the root ball of the plants with soil. Next, you could eliminate air pockets by tamping the soil mildly.

How do I kill weeds in my succulents?

Physical method (hand removing)

As you may understand, it becomes very unpleasant to spot weeds spreading across your succulent gardens. 

Further they would be absorbing the moisture from your succulents as well. However, it would be challenging for you to reach the weeds and to take them off also.

Having said that, removing the weeds manually would be the best option if you want to get rid of them whilst ensuring that you do not harm your succulents. 

You could use the appropriate and right tools to get rid of weeds whilst making sure that your succulent garden is weed free too. 

In addition to that, if you keep weeding on a constant basis, you could avoid them spreading to a greater level too. 

This is by far the safest way of getting rid of weeds from succulents and keeping them safe from invasive plants such as from weeds. 

Further you may use a pair of tongs to take whatever fragile succulents available prior to you take the weeds off. 

Apart from that, you may use a dandelion digger also to pull weeds which consist of longer roots as that will not cause any damage to the plants.

Chemical methods (herbicides)

If you wish to use chemical methods to get rid of weeds, you may use pre emergent herbicides which comprise dithiopyr. 

However, you could use them only if you wish to avoid the weeds seeds germinating. 

On the other hand, you may use post emergent herbicides such as glyphosate to eradicate weeds from succulent beds. You could further use it for cactus beds as well.

The reason for that is because they could damage only a specific set of plants and further, they have a minor residual effect as well. 

Be careful when applying these chemicals and always follow  the labelled instructions. 

Be extra cautious when you are applying these for succulents which have shallow roots as they would be extra responsive towards specific formulations.
