It will seem strange, but leaving a nail in the plants before being away for a long time is an effective trick. That’s what’s for.

Nails in the vase

When preparing to go on vacation, one of the common problems we face is how to keep our plants hydrated in our absence. Watering plants regularly may not be possible if we are away for a long period of time. That is why many are adopting an unusual but effective method – leaving a nail in plants as a do-it-yourself irrigation system.

Leave a nail in the plants to water them

To make this system, you will need a nail at least 10 cm long and a meter and a half of natural thread that is able to absorb water, such as wool, cotton or hemp thread. Also, get yourself a bottle, considering that a larger bottle will have a greater water release capacity and will last longer.

Nail in plants

Let’s start with the assembly of the system. Take the nail and the wire, leaving one end of the wire about 10 cm above the head of the nail. Then wrap the whole nail with the thread, leaving only 1-2 cm of free wire on the tip. Once you have completely wrapped the nail, make a knot to secure the thread. Now you will have two ends: one of 10 cm to leave above the head of the nail and the other longer.

Take the longest end of the wire and attach a counterweight to it, such as a longer nail or bolt. Tie the counterweight firmly to the wire. At this point, immerse the entire newly created system in water for a few minutes. The thread will absorb water and become soaked and wet.

After a few minutes, take the system out of the water and take the bottle. Then, fill the water bottle and insert the counterweight with the wire inside the bottle. Make sure that the nail goes into the ground inside the pot where the plant is located. In this way, the water will be distributed to the roots of the plants through the principle of capillarity.

How does that work? The principle of capillarity is based on the property of water to rise in small tubes, such as the blood vessels of plants. Through cohesion and adhesion forces, water moves against gravity, ensuring the irrigation of plants through capillary transport.

Watering plants

With this simple artisanal irrigation system, water will be gradually released to the roots of the plants, keeping them hydrated over time. The absorbent wire acts as a transport channel, transferring water from the bottle to the surrounding soil.

As the soil dries out, water will gradually be carried by the fibers of the wire, and it will fall into the soil drop by drop, providing constant and appropriate watering for the plants.

A nail in plants saves the holidays

This DIY irrigation method is affordable, environmentally friendly and can be a lifesaver for those who wish to travel without worrying about their beloved plants.

However, it is important to take into account the specific needs of the plants you want to irrigate in this way. Some plants, in fact, may require more or less water, so it is advisable to do some tests and carefully monitor the plants during our period of absence.

So, if you need a practical solution for watering plants during your holidays, why not try this creative and economical method?
