Can you use hydrochloric acid to kill tree's conifers?

Using hydrochloric acid to kill conifers is not recommended, as it can cause severe damage to the soil and surrounding ecosystem. While it may effectively harm the tree, the acid can also leach into the ground, affecting nearby plants and microorganisms. It's safer and more environmentally friendly to use targeted herbicides or other methods for tree removal. Always consider the ecological impact before using harsh chemicals.
