Are you wondering why some people bury coins in ZZ plant pots?—Here is the secret revealed of this surprising tradition!
Pennies and ZZ plants—What could be the connection? It turns out that there are a few perks to coins when used wisely for plants, especially copper coins. These coins have antifungal capabilities and a knack for warding off pests. Let’s dive deeper into these reasons why and how this tradition works for gardeners!
Growing Requirements of ZZ Plants
ZZ plants seem to enjoy thriving most in partial to deep shade and highly organic or sandy soil with good drainage. They have bulbous, fleshy rhizomes that give rise to glossy leaves that store water and make them drought-tolerant as well.
As a houseplant, well-drained potting soil is very important, and the watering cycle should be allowed to dry out between waterings because ZZ plants do not tolerate wet feet at all! Besides, the use of a balanced fertilizer once or twice a year helps maintain their health. Basically, this plant can be treated in much the same way as cacti and other succulent plants.
Why Some People Bury Coins in ZZ Plant Pots?
1. Works As A Natural Fungicide
Older pennies, particularly those minted before 1982 in the US, contain a higher copper content. When these pennies corrode, the copper ions slowly release into the soil which can be beneficial in preventing diseases like blight, root rot, or other fungal infections.
Additionally, the slow release of copper doesn’t even overwhelm your ZZ plants. It ensures that only a trace amount, is added to the soil. So, by strategically placing copper pennies near the base of your plants, you’ll see a reduction in fungal diseases without the need for harsh chemical fungicides.
2. Keeps Slug and Snails At Bay
The most common nuisances in our gardens—slugs and snails! But did you know that a copper coin can fix all this? There is scientific evidence that metals like copper and aluminum can ward off pests like these.
When these pests come in contact with copper, it causes a mild electrical shock-like reaction, which deters them from crossing over it. So, by burying pennies around the perimeter or placing them in a ring around susceptible plants, you create a defensive shield against these critters.
3. Improves Soil Quality and pH
ZZ plants generally require a suitable soil mix to reach optimum growth, and like many other plants, they rely on their rhizomes to store nutrients and water. On the other hand, these rhizomes are prone to rot if the soil becomes waterlogged or has an imbalanced pH range of (6.0 to 7.0).
Soil naturally contains copper, ranging from 2 to 100 parts per million (ppm). However, when it comes to potted soil, the quantity varies, and sometimes it is very low. This is where the role of pennies comes into play in balancing out the pH, increasing copper content, and improving soil porosity.
4. Boosts Plant Health
Copper (Cu) is one of the 8 essential micronutrients necessary for the development and growth of plants. Without adequate copper, plants fail to grow properly. It is required for many enzymatic and metabolic activities in chlorophyll production.
So, a coin in the pot of your ZZ plants will help balance the overall soil and plant health, promoting lush green growth and maintaining nutrient levels.
5. A Sign of Good Luck and Wealth
Ever heard of the saying, “A penny for good luck”? Well, some people take it literally! In many cultures, dropping a coin into a plant pot is thought to bring wealth and prosperity. The ZZ plant is already known as a lucky plant, and adding a penny just doubles the charm. Some believe it helps attract positive energy and abundance, making their home feel even more welcoming.
From acting as a natural pest deterrent and fungicide to enriching the soil, who would have thought that a penny could be of so much benefit to plants and soil? Tell us if you know of more interesting traditions and practices in your region.
