Vinegar and Your Plants

One thing to keep in mind when using vinegar for cleaning greenhouse is that you should be careful around your plants. Vinegar is known for being a natural herbicide, we have used it in our backyards as a means of controlling the weeds without harming the environment.

This is thanks to the acetic acid that you find in vinegar. While it is great to get rid of those annoying weeds, caution should be used when you use this in your greenhouse.

Vinegar works because when we spray it onto the weed, the waxy layer that protects the plant from water loss is stripped off. The weed then dries out and dies. However, if this happens to a plant you care about, desiccation causes that plant to die.

Therefore, be sure all fans are turned off and make sure no wind is blowing around so that vinegar that you spray doesn’t hit the plants you want to protect.

You might keep it concentrated by aiming your spray bottle through a paper cup with the bottom removed.
