Pounding nails in a lemon: the trick that will save your houseplants

Whether for skin, cleaning or cooking, lemon has proven itself time and time again. But did you know, dear readers, that it is also an excellent fertilizer for your houseplants? What if we told you that you only need to add a few nails to ensure its effectiveness? To pique your curiosity, we decided to share with you our simple trick on how to use this lemon and nail combination and breathe new life into your beautiful plants. It’s quite simple, just follow these steps:

  • First, take a lemon and roll it on a hard surface.
  • Next, get some nails and simply stick them into your citrus.
  • Let them sit in a dry place for 12 hours. (At this point, the nails will release their iron oxide, which will naturally transfer into the citrus.)
  • Time is up. Now remove the nails and squeeze the lemon juice.
  • All you need to do is to add the juice recovered to a quart of water.
  • Mix everything well, pour the solution into a spray bottle and spray your liquid on your houseplants (especially those that prefer acidic soil).

This iron oxide water is beneficial for plants that lack iron and do not grow in acidic soil. This water provides them with the sufficient amount of these minerals that they lack. No more yellow leaves caused by iron deficiency, among other things. And here we go! It is a very simple and effective way to rebalance the pH of your plants and give them new life. We can see your famous question coming: How is lemon beneficial to plants? Read on to understand!

What are the benefits of lemon juice for houseplants?

Lemon juice provides countless plant benefits, including:

  • Balance the pH of the soil: In fact, lemon juice is acidic, so it helps to lower the pH of the soil, especially if the soil is too alkaline.
  • Provide nutrients: Lemon juice is packed with nutrients like vitamin C, antioxidants, and minerals like calcium and potassium that are beneficial to plants.
  • Repel insects: Yes, lemon juice is considered a natural insecticide. Therefore, it is often used to repel harmful insects in a garden.
  • Eliminate bad odors: the deodorizing properties of lemon juice not only eliminate stubborn odors in the house, but also in the garden (vegetable garden, pond, animal urine, etc.).
  • Promote flowering: the citric acid in lemon juice can stimulate flowering and prevent root rot in some plants, including orchids.

Our lemon nail combination is not limited to this one application, think again! It can be used for other purposes, and this trick will shed some light on you (literally and figuratively).

How do you make a battery and start a fire with a lemon?

Did you know that you can start a bonfire with a simple lemon? However, it is completely TRUE! Do not underestimate this small citrus fruit! In fact, you can turn it into a battery, and it has enough energy to start a fire. We will show you how to do it safely!

  • First, start by rubbing the fruit between your hands to soften it a bit (this is necessary to help you insert the nails).
  • Then plant the nails about 0.5 inch apart.
  • Then form a row parallel to the first nails and drive zinc nails.

It is ready? Now, using a piece of wire, connect the first thumbtack to the second nail, then the second thumbtack to the third nail and so on. Finally, connect a piece of insulated electrical cable to the first nail and do the same for the other end with the last thumbtack. For clarity, the copper nail (top row far right) corresponds to the negative terminal and the thumbtack (bottom row far left) corresponds to the positive terminal. Your little lemon is now capable of producing about 0.9 volts of electricity, enough energy to start a fire. To test if the trick is working properly, all you need to do is place steel wool on a dry surface and add a dry fuel, such as toilet paper. Then all you need to do is touch the steel wool to both poles (plus and minus) to start your fire, and you’re done.


For your safety, dear readers, please note that it is imperative that this experiment be conducted in a safe place, away from flammable objects, to avoid fire hazards. Of course, your safety comes first, especially when it comes to handling fire! Basically, pounding nails into a lemon may seem strange at first, but it’s actually a fun and creative activity. Plus, it can have practical and useful applications for your home and garden. So why not give it a try?
