Will Muriatic Acid Kill A Tree

Need an alternative for herbicides to get rid of a pest-ridden or unwanted tree in the garden? 

Perhaps, it’s time to try muriatic acid. This aqueous and colorless solution of hydrogen chloride is a common household item that I often use to renew my swimming pool, clean concrete floors, and kill mold. 

But, the question remains — will muriatic acid kill a tree? Indeed, it can — with these four simple steps. 

How To Kill A Tree With Muriatic Acid

Step 1 

Before working with muriatic acid, you must always wear protective gear to prevent skin burns and other accidents. Now, read the instructions on the label and mix the acid with water according to the manufacturer’s recommendations. 

Step 2 

Using a shovel, dig a circle around the base of the tree. Ensure that the trench is deep enough and the roots are visible. 

Step 3 

Once the roots are exposed, you can pour the solution onto the roots. Since muriatic acid is a diluted form of hydrochloric acid, you may need to experiment with the ratios in the solution. 

That said, you may need a higher concentration of the acid, depending upon the species and maturity of the tree.  

Step 4 

Once the acid eats away the roots, you can ax down the tree at its base. Then, apply the solution onto the surface of the stump to ensure that the tree absorbs the acid. 

Safety Precautions 

While you can use muriatic acid to kill a tree, I recommend looking for safer alternatives first. In fact, there are plenty of herbicides on the market that are designed for that purpose. But, if you don’t have any other options, here are some essential things to remember before using this harsh chemical: 

1. Wear Protective Gear 

Always wear protective gear while handling muriatic acid. Apart from safety goggles, a face shield, rubber boots, and acid-resistant gloves, you must wear a long-sleeved shirt and long pants. 

Ensure that you immediately wash the affected area with water in case of any splashes. Also, consider keeping a neutralizing agent nearby. 

2. Keep Away From Children And Pets 

Always use muriatic acid in a well-ventilated area away from children and pets. On that note, you must carefully store any leftovers in places that are out of their reach. 

3. Always Dilute Muriatic Acid 

Muriatic acid should never be used in full strength, and you must always dilute it with water in a plastic bucket. Also, do not combine it with other chemical cleaning products.
