Why Weeds Are So Difficult to Control
Weeds are remarkably resilient because they have evolved to survive harsh conditions.
Many species:
Grow quickly
Produce thousands of seeds
Develop deep root systems
Tolerate drought
Spread underground
This means that simply removing the visible part of the plant is not always enough.
Some weeds can regrow repeatedly from roots hidden deep below the surface.
The Ingredients Behind This Homemade Spray
This popular mixture relies on four main ingredients:
White vinegar
Salt
Citric acid
Liquid dish soap
Each ingredient plays a specific role in damaging the weed.
The science behind each ingredient continues on the next page.
White Vinegar
White vinegar contains acetic acid.
When sprayed directly onto leaves, the acid damages plant tissues and removes moisture from the surface cells.
As a result, the weed begins to wilt and dry out.
Kitchen Salt
Salt is one of the most powerful components in the mixture.
